In the tests I've done on Windows Vista and MSVC++ 10 with -O2, executables built with release version of Boost Serialization are more than two times the size of executables built with Ebenezer Enterprises' approach. On Linux the stripped Boost executables are more than 4 times larger than their Ebenezer counterparts. http://webEbenezer.net/comparison.html Regards, Brian Wood http://www.webEbenezer.net (651) 251-9384 <http://frankrosenbloom.com>

[multi_array] compiling and changing an example
by sean farrow 25 Jan '10

25 Jan '10

Hi: I'm tryingto use boost::multi_array, I've included boost/multi_array.hpp in the file and have the following code: private: typedef boost::multi_array<double, 3> array_type; typedef array_type::index index; array_type test(boost::extents[3][4][2]); Commenting out the third line compiles fine, but leaving this in gives a c2061 error. It seems there is an issue with boost::extents, which header is this in? I don't have a using boost; earlier, should I have? I'm using visual c+ 2008. Any help apreciated. Sean.

[asio] Throwing an exception on timeout
by Pascal Kesseli 24 Jan '10

24 Jan '10

Hi folks While reading out a serial interface with boost asio, I used the following timeout protection: const boost::function<void(const error_code &)> SerialInterface::ON_TIMEOUT(if_then(_1 != error::operation_aborted, throw_exception(bind(constructor< SerialInterfaceTimeoutException> ())))); // ... void SerialInterface::read(void *buf, size_t size) throw(SerialInterfaceTimeoutException) { charTimeout.expires_from_now(maxCharDelay); charTimeout.async_wait(ON_TIMEOUT); // ... If a timeout occurs, the exception is thrown as expected. However, it is not handed any further from read, but instead the program terminates with a message concerning the exception. Is there any method having a throw() constraint in this async_wait chain? Thanks for any hint and best regards Pascal _________________________________________________________________ Personalisiere dein Messenger, inklusive persönliche Smileys ;-) Überrasche deine Freunde - wir zeigen dir wie's geht. http://rubrik.ch.msn.com/reportagen/personalisieren.aspx

[BGL] astar_search with VertexList=listS and bundled properties - binary '[' : no operator found
by liong＠gmx.ch 24 Jan '10

24 Jan '10

Hi all I'm stuck trying to get astar_search with VertexList=listS to compile properly with MS VC 2008SP1 or gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu9)gcc-4.4.1 using boost_1_41_0: I tried two approaches: The first is to have the vertex index as a member of the bundled vertex properties and the second is to have the vertex index as an exterior property map. Both approaches result in the same errors (with VC) and after reading a lot of docs, i'm even more confused and still cannot figure how to get rid of them. I'm new to BGL and and thankful for any suggestions.

[BoostCon 2010] Final Call for Participation
by Hartmut Kaiser 24 Jan '10

24 Jan '10

Please distribute! -------------------------------- 4th Annual Boost Conference 2010 -------------------------------- Aspen CO, USA, May 10-14, 2010, www.boostcon.com Final Call for Participation -------------------------------- Important dates: Proposal submissions Extended to January 3, 2010 Proposals decisions sent January 25, 2010 (tentative program available) Fully scheduled program available February 10, 2010 Session materials due April 15, 2010 -------------------------------- We invite you to submit session proposals to the 4th Annual Boost Conference: BoostCon 2010 (Aspen CO, USA, May 10-14, 2010). Traditionally the main face-to-face event for all things Boost (www.boost.org) BoostCon 2010 will present leading speakers from the whole C++ community. From using the Boost libraries to writing and maintaining them, from evangelizing to deploying Boost within your organization, from infrastructure and process to vision and mission, and the new C++ Standard, BoostCon brings together the sessions, the colleagues, and the inspiration to support your work with C++ and Boost in particular for the next year. To reflect the breadth of the Boost community, the conference includes sessions aimed at two constituencies: Boost end-users and hard-core Boost library and tool developers. The program fosters interaction and engagement within and across those two groups, with an emphasis on hands-on, participatory sessions. Session topics -------------- Topics of interest include, but are not restricted to, the following: * General tutorial sessions introducing one or more Boost libraries * In-depth sessions on using specific Boost libraries * Case studies on using Boost * Experts panels * Advanced sessions on implementation techniques used within Boost libraries * C++0x and how it will change life for users and library writers * Development workshops to extend or enhance existing Boost libraries * Workshops on design process * Infrastructure workshops such as Build tools, Website, Testing * Concepts and Generic Programming * Hardware and infrastructure presentations focused on how libraries can make better use of the technology * Other topics likely to be of great interest to Boost users and developers Interactive and collaborative sessions are encouraged, as this is the nature of both the on-line Boost community and the style of learning and participation that has proven most successful at such events. Sessions can be tutorial based, with an emphasis on interaction and participant involvement, or workshop based, whether hands-on programming or paper-based, discussion-driven collaborative work. Session formats --------------- Presentations Presentations focus on a practitioner's ideas and experience with anything relevant to Boost and Boost users. Panels Panels feature three or four people presenting their ideas and experiences relating to Boost's relevant, controversial, emerging, or unresolved issues. Panels may be conducted in several ways, such as comparative, analytic, or historic. Tutorials Tutorials are sessions at which instructors teach conference participants specific Boost-relevant skills. Workshops Workshops provide an active arena for advancements in Boost- relevant topics. Workshops provide the opportunity for experienced practitioners to develop new ideas about a topic of common interest and experience. Author's Corner Presentations These were introduced at BoostCon 2008, and were a great success. They are short (30 minute) sessions, focusing on tips on usage and design. In addition, we're looking to uncover the hidden design gems in Boost libraries. Tool Vendors Presentations We actively encourage tool vendors and ISP's to submit proposals for a special Tool Vendors Session Track aimed at products related to Boost and C++ (compilers, libraries, tools, etc.). Other formats may also be of interest. Don't hold back a proposal just because it doesn't fit into a pigeonhole. Submitting a proposal --------------------- Standard Sessions are 90 minutes. You may submit a proposal for fractions or multiples of 90-minutes. Fractional proposals will be grouped into 90 minute sessions covering related topics. Longer sessions, such as tutorials and classes, will be assigned 90 minute, three hour (i.e. half day), or six hour (i.e. full day) time slots. Please include: * The working title. * Type of session: presentation, panel, tutorial, workshop, authors corner, vendor track, other. * A paragraph or two describing the topic covered, suitable for the conference web site. * Proposed length: 10-20 minute short talks, 45 minutes, 90 minutes, half day, full day. * Alternate lengths, if you are willing to make adjustments: 10-20 minute short-talks, 45 minutes, 90 minutes, half-day, full day. * Audience: users, developers, both. * Level: basic, intermediate, advanced. * A biography, suitable for the conference web site. * Your contact information (will not be made public). Submission details ------------------ All submissions have to be done through the EasyChair conference management system: http://www.easychair.org/conferences/?conf=boostcon10. If you have not already registered at EasyChair, you will need to do so in order to submit your proposal. All submissions will go through a peer review process. Authors are invited (but are not required) to submit PDF versions of full papers of up to 10 pages in ACM conference proceedings format (see http://www.acm.org/sigs/publications/proceedings-templates) The full papers are not required unless you want them published in the proceedings. All accepted proposals will be made available in the Association for Computing Machinery (ACM) Digital Library (approval pending). Best papers, after further reviews, will be considered to be book chapters or journal articles in a renowned journal. The session materials go on the BoostCon website and will be available to attendees. For general information on the BoostCon 2010 paper submission or the scope of technical papers solicited, please refer to the conference website at www.boostcon.com. For any other questions about the submission process or paper format, please contact the Program Committee at boostcon10(a)easychair.com.

binary size:boost::serialization and boost::variant
by Tyler Littlefield 24 Jan '10

24 Jan '10

Hello, When working with the serialization my project's binary isn't overly bloated, until I add in the serialization. The debug size becomes about 13M with the size of the binary with symbols stripped being about 1.1M larger than before I included the variant.hpp. Is there any reason for this, or a way it can be solved? I'd rather not distribute a binary this large if I can help it. Thanks, Tyler Littlefield http://tds-solutions.net Twitter: sorressean

generate an n-deep runtime for loop
by Hicham Mouline 24 Jan '10

24 Jan '10

Hello, I have a fusion sequence of optionals, for e.g. fusion::vector< optional< variant< std::vector<double>, triplet<double>, pair<double>, double> >, optional< variant< std::vector<int>, triplet<int>, pair<int>, int> >, optional< variant< std::vector<double>, triplet<double>, pair<double>, double> > > The size of fusion::vector is variable. The optionals are never empty. In 1 possible instance of this fusion vector, we have these runtime values { 5.5, 10.1, 15.7, 30.9 //std::vector<double> v1 5:15:5 // triplet<int> range from 5 to 10 incrementing with 4 5.4 // double, value fixed at 5.4 } I wish to generate at runtime the following code (not always 3-deep for loops, the 3 would be known at compile time, but the bounds of the indices in the for loops are only known at runtime) for (size_t index1=0; index1< v1.size(); ++index1) { for (int index2=5; index2<=15; index2+=5) { for (double index3=5.4; index3<=5.4; ++index3) { // some code } } } is this possible? regards,

bjam library build problem in 1.41 for VS 2005?
by Jeff 24 Jan '10

24 Jan '10

After installing Boost 1.41, I am having some library file problems which I think were caused by not building boost correctly. I built boost using the following commands: bootstrap .\bjam When I link an application that uses Regex, this is what happens: LINK : fatal error LNK1104: cannot open file 'libboost_regex-vc80-mt-s-1_41.lib' Please note that I have included the stage\lib into my VS library include options. The problem is that that file does not exist but this one does: C:\boost_1_41_0\stage\lib\libboost_regex-vc80-mt.lib How do I get the *mt-s-1_41.lib versions to build? Thank you Running Visual Studio 2005, Windows XP

23 Jan '10

Hi all, I would like to build boost library 1.36.0 on the 64 bits linux machine. In fact, I install it, but when I run my code, I got the segmentation faults. So, I found the web site to solve this problem... http://old.nabble.com/How-to-build-32-bits-boost-library-on-a-64-bits-platf… At this site, they say I have to use "address-model=32 architecture=x86" arguments to bjam, but I do not know how can I use this arguments. Do I have to install the bjam separately? If someone knows that, please let me know. Thanks,

Adding a thread to a Singleton class
by Stephen Torri 23 Jan '10

23 Jan '10

I would like to have a logging class, called Trace, that I can off load the string formatting of logging the status of my program to a separate thread. Right now my logging class is written as a singleton object. This code is located within a shared library and used extensively in it to write tracing information to a file. Right now all the string formatting occurs on the main thread which degrades performance. QUESTION #1: I was wondering if the way in which I am attempting to have a central point for logging information via a Singleton without passing around a variable is a practical solution to this problem? I followed the Singleton guideline from Boost cookbook ( http://www.boostcookbook.com/Recipe:/1235044 ) of how to implement my singleton. I was thinking that I could add a boost::thread to my logging class, called Trace, and use a queue to pass objects over to be logged. A boost::condition would be used to signal the boost::thread to wake up and lock the queue, copy the contents then start writing the string formatted to a file. Below is my initial code. I would appreciate comments on the design, ideas for better designs and suggestions. Stephen Torri ---------------- SINGLETON class ---------------------------- #ifndef SINGLETON_H #define SINGELTON_H #include <boost/utility.hpp> #include <boost/thread/once.hpp> #include <boost/scoped_ptr.hpp> namespace myproject { namespace trace { template <typename T> class Singleton : boost::noncopyable { public: static T& Instance() { boost::call_once ( init, m_flag ); return *m_obj; } static void init () { m_obj.reset ( new T () ); } protected: ~Singleton(){} Singleton(){} private: static boost::scoped_ptr<T> m_obj; static boost::once_flag m_flag; }; } // namespace trace } // namespace trace template <typename T> boost::scoped_ptr<T> myproject::trace::Singleton<T>::m_obj ( 0 ); template <typename T> boost::once_flag myproject::trace::Singleton<T>::m_flag = BOOST_ONCE_INIT; #endif // define SINGELTON_H ---------------- Trace class ----------------------- #ifndef myproject_TRACE_H #define myproject_TRACE_H #include <boost/cstdint.hpp> #include <boost/shared_ptr.hpp> #include <boost/thread/mutex.hpp> #include <boost/thread/condition_variable.hpp> #include <boost/thread/thread.hpp> #include <boost/utility.hpp> #include <vector> #include "Trace_State.h" namespace myproject { namespace trace { // // Turn Trace into a singleton class that contains a worker thread // - Wait for data // - If data exists then process // - Else wait // Add method for adding a ITraceable object.

[program_options] prompt for a password
by "Stanisław T. Findeisen" 23 Jan '10

23 Jan '10

[This question is about Boost.program_options library.] Sometimes you need a password option, but you don't want it specified as a program parameter (so that it won't be visible to other users via, for example, ps(1)). Is prompting for an option supported by Boost.program_options? STF http://eisenbits.homelinux.net/~stf/ OpenPGP: DFD9 0146 3794 9CF6 17EA D63F DBF5 8AA8 3B31 FE8A

[Asio] read_some throws exception with IOCP disabled
by Collin Dauphinee 22 Jan '10

22 Jan '10

I have a piece of code that works completely fine with IOCP enabled, but when I disable it via the BOOST_ASIO_DISABLE_IOCP define, any attempts to call socket.read_some will throw an exception. This exception states that "An operation was attempted on something that is not a socket." However, I am able to write to this socket without problems; no exception is thrown and the data is received by the server. I've also tried reading and writing with the native Windows socket. Any calls to send() will succeed, but calls to recv() will return the error given above. This includes a write, read, write sequence; the first write will succeed, the read will fail, the second write will succeed even though the read told me that the handle isn't a socket. Only synchronous operations are being done on this socket. It's connected normally, no strange options are set on it, etc; the code is more or less the same as that found in the synchronous TCP client examples. Any solutions or workarounds to this problem would be greatly appreciated. I need to have IOCP disabled, so re-enabling it isn't a solution.

[uBLAS] howto combine sparse AND symmetric?
by Tim Odenthal 22 Jan '10

22 Jan '10

Hi! I need to solve the classical linear equation A*x=b with x the unknown vector and A a very large, sparse and symmetrical matrix. I want to try the conjugate gradient iterative method to solve the problem (unless somebody knows a definitely much better one). Now I've seen that uBLAS provides the symmetric_adaptor class - should I use this one in combination with one of the sparse matrix classes? Does this reduce the memory usage as compared to only using a sparse matrix? Many thanks in advance Tim Odenthal

[1.42.0] Beta 1 available on Sourceforge
by Beman Dawes 22 Jan '10

22 Jan '10

1.42.0 beta 1 is now available. This release contains one new library and numerous bug fixes for existing libraries. For details, including download links, see http://beta.boost.org/users/news/version_1_42_0 The release can also be downloaded directly from SourceForge. See http://sourceforge.net/projects/boost/files/ There are a few known problems in the beta: * An odd 'simplesectsep' tag that doxygen creates which has turned up in the generated documentation, such as at http://tinyurl.com/ygbgkge. * Doxygen isn't expanding some of the macros in Boost.Accumulators. * A nasty bug in Spirit affecting copy construction of rules (rev. 50156) has been tracked down and fixed, but the fix was too late for the beta. These will be fixed in the final release. Please report any other problems by responding to this message on either the users or the main developers mailing lists. Thanks, --The Boost release team

[Boost] [Fusion] Help with tuple adapter
by Bill Nell 22 Jan '10

22 Jan '10

Hi all, I'm having some trouble getting the boost fusion tuple adapter working (the one that makes boost::tuples into conforming sequence types). I'm assuming that the adapted tuple should now be a legal MPL sequence but mpl::is_sequence yields false and consequently mpl::for_each doesn't work on the tuple type either. The following program is an illustration of what I am trying to do. I guess I must be missing something simple? Any help would be appreciated. Bill #include <iostream> #include <typeinfo> #include <boost/mpl/is_sequence.hpp> #include <boost/mpl/for_each.hpp> #include <boost/fusion/tuple.hpp> #include <boost/fusion/sequence.hpp> #include <boost/fusion/iterator.hpp> #include <boost/fusion/mpl.hpp> #include <boost/fusion/adapted/boost_tuple.hpp> struct helper { template <typename TT> void operator()(TT) { std::cout << typeid(TT).name() << std::endl; } }; int main() { typedef boost::fusion::tuple<int,char,double> FTUP; typedef boost::tuple<int,char,double> BTUP; // this works std::cout << boost::mpl::is_sequence<FTUP>::value << std::endl; std::cout << "fusion tuple\n"; boost::mpl::for_each<FTUP>(helper()); // this doesn't work std::cout << boost::mpl::is_sequence<BTUP>::value << std::endl; // the following lines won't compile because the BTUP is not a // sequence type. //std::cout << "boost tuple\n"; //mpl::for_each<BTUP>(helper()); return 0; }

[thread] NULL cleanup routine for thread_specific_pointer
by Jeremiah Willcock 21 Jan '10

21 Jan '10

There was a post in 2008 (http://lists.boost.org/boost-users/2008/05/36589.php) about using a NULL cleanup function for thread_specific_ptr, but no response to the issue. It appears that there is now a special case in the code for thread_specific_ptr to not call NULL cleanup functions; is this official (and thus can be relied upon)? I did not see it mentioned in the documentation. -- Jeremiah Willcock

When the schedule is recreated, the driver is not copied to the bus_schedule as the field is contained in the nested struct. When I replace the second macro with the first one, the example works.

Question about the boost::thread_group
by watsonsong 21 Jan '10

21 Jan '10

I want to use thread_group for multi-thread, and maybe using it like this: void thread2(); void thread1(boost::thread_group& tg) { // create an other thread in the thread_group tg.create_thread(thread2); // do some work for(;;) { //... } } void thread2() { // do some work for(;;) { //... } } int main() { boost::thread_group tg; tg.create_thread(boost::bind(thread1, boost::ref(tg))); tg.join_all(); return 0; } I am puzzling about the join_all() function. Whether is it safe to invoke boost::thread_group::create_thread in an other thread and the join_all will wait for all the tow thread? I saw the source code of thread_group. It used a std::list to keep thread objects, and used a shared_mutex for synchronization. It lock on create_thread and shared lock on join_all. Is that mean if it run on "tg.join_all()" in main thread before "tg.create_thread(thread2);" in thread1, the "tg.create_thread(thread2);" will lead to a dead-lock because the "tg.join_all()" wait for thread1 finish, and thread1 wait for "tg.join_all()" finish on "tg.create_thread(thread2);" If it is so, how can I implement such a function? Thank you. -- View this message in context: http://old.nabble.com/Question-about-the-boost%3A%3Athread_group-tp27220440… Sent from the Boost - Users mailing list archive at Nabble.com.

[interprocess] shared map of string to string?
by Anthony Foiani 21 Jan '10

21 Jan '10

I'm using boost.interprocess to build a map from string to string that can be shared between multiple processes, with all read/write access protected by a mutex. I'm having a hard time making it work. Here's a cut-down version of the declaration: template < typename KeyType, typename ValueType, typename StoredKeyType = KeyType, typename StoredValueType = ValueType > class SharedMap : private boost::noncopyable { public: SharedMap( const std::string & shmName, const std::size_t shmSize, const std::size_t initBucketCount = 10 ); ~SharedMap(); void setOneValue( const KeyType & key, const ValueType & value ); bool getOneValue( const KeyType & key, ValueType & value ); void clear(); private: typedef std::pair< const StoredKeyType, StoredValueType > StoredPairType; typedef boost::interprocess::managed_shared_memory ShmManagerType; typedef boost::interprocess::allocator< StoredPairType, ShmManagerType::segment_manager > ShmAllocatorType; typedef boost::interprocess::interprocess_mutex ShmMutexType; typedef boost::interprocess::scoped_lock< ShmMutexType > ShmScopedLock; typedef boost::unordered_map< StoredKeyType, StoredValueType, boost::hash< StoredKeyType >, std::equal_to< StoredKeyType >, ShmAllocatorType > ShmMapType; std::string m_sShmName; ShmManagerType m_manager; ShmMutexType * m_pMutex; ShmMapType * m_pMap; }; // end class SharedMap typedef SharedMap< /* KeyType = */ std::string, /* ValueType = */ std::string, /* StoredKeyType = */ boost::interprocess::string, /* StoredValueType = */ boost::interprocess::string > SharedStringMap; And some important bits of the implementation: #define SHARED_MAP( ret_type ) \ template < \ typename KeyType, \ typename ValueType, \ typename StoredKeyType, \ typename StoredValueType \ > \ ret_type \ SharedMap< \ KeyType, \ ValueType, \ StoredKeyType, \ StoredValueType \ > SHARED_MAP()::SharedMap( const std::string & shmName, const std::size_t shmSize, const std::size_t initBucketCount /* = 10 */ ) : m_sShmName( shmName ), m_manager( boost::interprocess::open_or_create, shmName.c_str(), shmSize ), m_pMutex( m_manager.find_or_construct< ShmMutexType >( "mutex" )() ), m_pMap( m_manager.find_or_construct< ShmMapType >( "map" )( initBucketCount, boost::hash< StoredKeyType >(), std::equal_to< StoredKeyType >(), m_manager.get_allocator< StoredPairType >() ) ) { } SHARED_MAP()::~SharedMap() { try { m_pMutex->unlock(); } catch ( ... ) { } } SHARED_MAP( void )::clear() { ShmScopedLock lock( *m_pMutex ); m_pMap->clear(); } It works fine the first time I run the program, but on the second attempt I get a SIGSEGV when I try to clear the map. My test loop is basically: create or find map for each rep clear map insert values done GDB tells me that this error is originating here: Program received signal SIGSEGV, Segmentation fault. __libc_free (mem=0x8143a48) at malloc.c:3709 3709 if (chunk_is_mmapped(p)) /* release mmapped memory. */ (gdb) bt #0 __libc_free (mem=0x8143a48) at malloc.c:3709 #1 0x001efd12 in operator delete (ptr=<value optimized out>) at ../../../../libstdc++-v3/libsupc++/del_op.cc:44 #2 0x08053d49 in __gnu_cxx::new_allocator<char>::deallocate (this=0xb7fa4334, __p=0x8143a48 <Address 0x8143a48 out of bounds>) at /usr/lib/gcc/i686-redhat-linux/4.4.2/../../../../include/c++/4.4.2/ext/new_allocator.h:95 #3 0x0805e677 in boost::interprocess_container::containers_detail::basic_string_base<std::allocator<char> >::deallocate (this=0xb7fa4334, p=0x8143a48 <Address 0x8143a48 out of bounds>, n=24) at /usr/include/boost/interprocess/containers/container/string.hpp:309 #4 0x0805dac2 in boost::interprocess_container::containers_detail::basic_string_base<std::allocator<char> >::deallocate_block (this=0xb7fa4334) at /usr/include/boost/interprocess/containers/container/string.hpp:341 #5 0x0805d167 in boost::interprocess_container::containers_detail::basic_string_base<std::allocator<char> >::~basic_string_base (this=0xb7fa4334, __in_chrg=<value optimized out>) at /usr/include/boost/interprocess/containers/container/string.hpp:119 #6 0x0805bfe7 in {b::ic::string}::~basic_string (this=0xb7fa4334, __in_chrg=<value optimized out>) at /usr/include/boost/interprocess/containers/container/string.hpp:617 #7 0x0805d671 in std::pair<{b::ic::string} const, {b::ic::string} >::~pair (this=0xb7fa4334, __in_chrg=<value optimized out>) at /usr/lib/gcc/i686-redhat-linux/4.4.2/../../../../include/c++/4.4.2/bits/stl_pair.h:68 #8 0x08063636 in boost::unordered_detail::destroy<std::pair<{b::ic::string} const, {b::ic::string} > > (x=0xb7fa4334) at /usr/include/boost/unordered/detail/hash_table.hpp:233 #9 0x08062d55 in boost::unordered_detail::hash_table_data_unique_keys<ip::allocator<std::pair<{b::ic::string} const, {b::ic::string} >, ip::segment_manager<char, ip::rbtree_best_fit<ip::mutex_family, ip::offset_ptr<void>, 0u>, ip::iset_index> > >::allocators::destroy (this=0xb7f9f0d4, ptr=...) at /usr/include/boost/unordered/detail/hash_table_impl.hpp:133 #10 0x080619fc in boost::unordered_detail::hash_table_data_unique_keys<ip::allocator<std::pair<{b::ic::string} const, {b::ic::string} >, ip::segment_manager<char, ip::rbtree_best_fit<ip::mutex_family, ip::offset_ptr<void>, 0u>, ip::iset_index> > >::delete_to_bucket_end (this=0xb7f9f0d4, begin=...) at /usr/include/boost/unordered/detail/hash_table_impl.hpp:832 #11 0x0805fc63 in boost::unordered_detail::hash_table_data_unique_keys<ip::allocator<std::pair<{b::ic::string} const, {b::ic::string} >, ip::segment_manager<char, ip::rbtree_best_fit<ip::mutex_family, ip::offset_ptr<void>, 0u>, ip::iset_index> > >::clear_bucket ( this=0xb7f9f0d4, b=...) at /usr/include/boost/unordered/detail/hash_table_impl.hpp:867 #12 0x0805e2ff in boost::unordered_detail::hash_table_data_unique_keys<ip::allocator<std::pair<{b::ic::string} const, {b::ic::string} >, ip::segment_manager<char, ip::rbtree_best_fit<ip::mutex_family, ip::offset_ptr<void>, 0u>, ip::iset_index> > >::clear ( this=0xb7f9f0d4) at /usr/include/boost/unordered/detail/hash_table_impl.hpp:879 #13 0x0805d918 in boost::unordered_map<{b::ic::string}, {b::ic::string}, boost::hash<{b::ic::string} >, std::equal_to<{b::ic::string} >, ip::allocator<std::pair<{b::ic::string} const, {b::ic::string} >, ip::segment_manager<char, ip::rbtree_best_fit<ip::mutex_family, ip::offset_ptr<void>, 0u>, ip::iset_index> > >::clear (this=0xb7f9f0c4) at /usr/include/boost/unordered/unordered_map.hpp:271 #14 0x0805cdc3 in Tony::SharedMap<{std::string}, {std::string}, {b::ic::string}, {b::ic::string} >::clear (this=0xbffff40c) at SharedMap.cpp:203 #15 0x0804e3e4 in main (argc=1, argv=0xbffff744) at SharedMapTest.cpp:99 I've done the following substitutions: std::basic_string<char, std::char_traits<char>, std::allocator<char> > -> {std::string} boost::interprocess_container::basic_string<char, std::char_traits<char>, std::allocator<char> > -> {b::ic::string} ip:: -> ip:: Interestingly, it looks like the mutex survives program stops and starts just fine: if I try to run my test case a third time, it sits and waits on the mutex (which got locked just before the 'clear' crashed out in the 2nd invocation) Platform is GCC 4.4.2 (fedora rpm 4.4.2-20) with the RPM packages of boost (1.39.0-8). Any hints would be very much appreciated. I can get a full working test case up on the web, but I need to pull out some bits (especially from the test routine) that rely on other parts of my project. Alternately, if anyone knows of a freely-available implementation of this functionality (or, even better, one that stores std::strings directly instead of having to go to/from b::ip::strings, and maybe one that auto-sizes its shared memory pool)... I'd *definitely* like to hear about that. :) Thanks in advance! Regards, Tony

bimap<int, shared_ptr> question
by philip tucker 21 Jan '10

21 Jan '10

I want a bimap<int,shared_ptr> in which the rhs is ordered not by pointer, but by thing pointed to. Can you give me a simple example to follow? I know this is a naive question, but I have searched the docs long and hard for such an example. If one appears, I'd be interested in knowing where. Thanks in advance.

[chrono] v0.3.1 Support for wide characters
by vicente.botet 20 Jan '10

20 Jan '10

Hi, this new version includes: * Added support for wide characters on formatters. * Added chrono.hpp and stopwatches.hpp header files at the boost level. * Update of the doc taking care of preceding comments. Comments are welcome :) Best, Vicente ----- Original Message ----- From: "vicente.botet" <vicente.botet(a)wanadoo.fr> To: <boost(a)lists.boost.org>; <boost-users(a)lists.boost.org> Sent: Sunday, January 17, 2010 9:14 PM Subject: [chrono] v0.3 New Stopwatch Feature Hi, I'm pleased to announce the new version of the Boost.Chrono library. The implementaton is quite stable; the new interface could suffer of some modifications, renaming, ... as far as you submit some proposals. I would request a formal review soon and I will need a review manager. I know that review managers are hard to find, so if you are interested in the library, please the Review Wizards. The library can be downloaded from http://www.boostpro.com/vault/index.php?action=downloadfile&filename=chrono… and the documentation is online on the sandbox http://svn.boost.org/svn/boost/sandbox/chrono/libs/chrono/doc/html/index.ht…. I've tested it with gcc and MSVC. Previoous version of the library have been testted on Mac, but I'm not able to test this platform. Could someone check if there are some regressions on Mac? New Features: * Process cpu clocks * Independent process cpu clocks for real, user, system process CPU time * Global process cpu clock for real, user, system process CPU time * Stopwatch concept measuring elapsed time between different points in time associated to the operations start, stop, suspend and resume. * stopwatch is a model Stopwatch measuring the elapsed time between the start and the stop operations. * stopwatch_accumulator is a model Stopwatch allowing to accumulate several time samples and give the average, ... * Scoped helper classes allowing to pairwise start/stop operations, suspend/resume and resume/suspend a Stopwatch. * Stopwatch Formatter concept * stopwatch formatter "%ds\n" * stopwatch accumulator formatter "%c times, sum%ss, min%ms, max%Ms, mean%as\n" * time formatter "real %rs, cpu %cs (%p%), user %us, system %ss\n" * digital_time decomposition class separating days, hours,minutes,seconds, nanoseconds from any duration class (looking for a better name) * digital_time formatter "%d days(s) %h:%m:%s.%n\n" * stopwatch_reporter is a convenient generic class reporting elapsed time for the Stopwatch concept. * stopclock<Clock> shortcut stopwatch_reporter<stopwatch<Clcok>> * typeof registration for classes duration and time_point Depreceated Features: * The classes process_times, process_clock, process_timer, timer and run_timer are now deprecated as the preceding additions are more generic. However for backward compatibility they are preserved until inclusion of the library in Boost. Next follows the equivalences: timer<> ~ stopwatch<> process_timer ~ stopwatch<process_cpu_clock> run_timer ~ stopclock<> Bug Fixes * Try to correct warning C4251: 'boost::chrono::run_timer::m_format' : class 'std::basic_string<_Elem,_Traits,_Ax>' needs to have dll-interface to be used by clients of class 'boost::chrono::run_timer', by don't including inlines functions using the std::string m_format. For people that doesn't know it yet, Boost.Chrono library provides: * The C++0x Standard Library's common_type. * The C++0x Standard Library's compile-time rational arithmetic. * The C++0x Standard Library's time utilities, including: * Class template duration * Class template time_point * Clocks: * system_clock * monotonic_clock * high_resolution_clock * typeof registration for classes duration and time_point * Process clocks: * process_real_CPU_clocks, capturing real-CPU times. * process_user_CPU_clocks, capturing user-CPU times. * process_system_CPU_clocks, capturing system-CPU times. * process_cpu_clock, tuple-like class capturing at once real, user-CPU, and system-CPU times. * Stopwatches: * stopwatch, capturing elapsed Clock times. * stopwatch_accumulator, capturing cummulated elapsed Clock times. * scoped helper classes allowing to pairwise start/stop operations, suspend/resume and resume/suspend a Stopwatch. * Stopclocks or Stopwatch reporters: * stopwatch_reporter, convenient reporting of models of Stopwatch results. * stopclock<Clock> shortcut of stopwatch_reporter<stopwatch<Clock>> Best regards, _____________________ Vicente Juan Botet Escribá

[Boost][statechart] Any way to print events received by a state even discarded ones
by Babi Seal 20 Jan '10

20 Jan '10

Hi, I am struggling to figuring out when sometime I invoke process_event on a state-machine in a specific state I do not see the necessary transition taking place. I know I am in a specific state because I log everytime I enter a state. Post mortem also I use the custom_static_type_ptr and state_iterator code to print the state the machine is in and I am able to confirm that I am in that said state. I initially had defined a very straightforward state-machine and simple outer-state. And 9 out 10 times the simple event triggers the necessary transition but in a few instances I see no response/or transition. Is there some way to see if the event got silently discarded. Is it being queued to the state-machine, an exception event raised. I just want to understand what is happening. After the said event had occurred I print the state I expect to be in, print some member variables and things look ok so I am really at a loss for why the event would be just lost. Thanks - I really really appreciate any debugging guidance.

Boost uBLAS Sparse Matrices Question
by Eamonn Hynes 20 Jan '10

20 Jan '10

Greetings users, Anyone know how to convert a matrix<int> to a compressed_vector<int> using the boost/numeric/ublas/ library? Here is a code snippet: #include <boost/numeric/ublas/matrix.hpp> #include <boost/numeric/ublas/io.hpp> using namespace boost::numeric::ublas; using namespace std; #include <fstream> int A=2000; int D=2000; int main() { matrix<int> ADf(A,D); //Author-Document (full) fstream IN; IN.open("./eoh_ADf"); for(unsigned i=0;i<ADf.size1();++i) { for (unsigned j=0;j<ADf.size2();++j) { IN>>ADf(i,j); } } IN.close(); cout<<ADf<<endl; return 0; } I badly need to convert the matrix ADf into sparse form... Isn't there some function to convert ADf into ADs (AD sparse)? i.e. ADs=sparse(ADf)... Let's say ADf isn't a 2000x2000, but simply a 5x5: ADf=[[1,-1,0,-3,0],[-1,5,0,0,0],[0,0,4,6,4],[-3,0,6,7,0],[0,0,4,0,-5]] I want this converted to: values = [1 -1 -3 -2 5 4 6 4 -4 2 7 8 -5] columns = [1 2 4 1 2 3 4 5 1 3 4 2 5] rowIndex = [1 4 6 9 12 14] Any help that users can offer me would be much appreciated. Thanks in advance, Eamorr

uBlas and openMP?
by mik 20 Jan '10

20 Jan '10

Hi all, I'm working on a project using uBlas. I'm using dense vector and dense matrix, the dimensions of these structures are very big. So, I was thinking about the opportunity to modify some algorithms of uBlas using multi-thread programming. I've tried to do this using openMP. Below, you find my first attempt. This is a piece of the original code in vector_assign.hpp // Explicitly indexing template<template <class T1, class T2> class F, class V, class E> // BOOST_UBLAS_INLINE This function seems to be big. So we do not let the compiler inline it. void indexing_vector_assign (V &v, const vector_expression<E> &e) { typedef F<typename V::reference, typename E::value_type> functor_type; typedef typename V::size_type size_type; size_type size (BOOST_UBLAS_SAME (v.size (), e ().size ())); #ifndef BOOST_UBLAS_USE_DUFF_DEVICE for (size_type i = 0; i < size; ++ i) functor_type::apply (v (i), e () (i)); #else size_type i (0); DD (size, 2, r, (functor_type::apply (v (i), e () (i)), ++ i)); #endif } And I modified the inner for in this way: int i; #pragma omp parallel private(i) shared(v, e) { #pragma omp for for (i = 0; i < size; ++ i) functor_type::apply (v (i), e () (i)); } I tried the code and it run. Yes I know that it's better if I use the clause schedule in the pragma for, but the real question is: do you think that this code is enough general? Can I extend it with the operations? Thank you in advance Mirko --- Ad maiora semper.

Serialization of pointers ? --> loading not working ...
by Simon Ruffieux 20 Jan '10

20 Jan '10

Hello again ! I am continuing my structure serialization ... Seems I do not get something with pointers ... I have followed the "demo.cpp" example and tried to do the same as they are doing for pointers but I get an exception when trying to relaod my structure ! Hope someone can help me .... What I do: -Save a Particle structure. - this particle contains a SensoRreading class -this sensorReading has a pointer to a Sensor class (only containing a string) When I save(serialize) the particle, the file "out.txt" contains the following text: 22 serialization::archive 6 0 0 0 0 1.1000000000000001 4.4000000000000004 0 2.1000000000000001 8.4000000000000004 0 3 12.699999999999999 8.5 6 0 0 35 3 1 0 0 11 Sensor Name This seems correct to me ! But when I try to load it back in a particle using Particle p2 = Particle(); loadFromFile<text_iarchive>(p2, "out.txt"); It raises the follwoing error during compilation:

[spirit] boost 1.33.1, HP-UX ia64 & gcc-3.4.6 - doesn't work with optimization (-O2)
by Frank Bergemann 20 Jan '10

20 Jan '10

Hi, we have confirmation now from hp, that they could reproduce the problem (pls. see below). We here decided to switch to a newer gcc compiler version. And doing so we will also switch to a newer boost lib version. Actually we already tried the 1.41.0 with the old gcc-3.4.4. But for that there was a not backwards compatible change in boost::spirit impl. and API. So as we don't have time to adapt our application, i guess we need to use the 1.40.0? cheers, Frank ---- reply from hp ---------------------------------------------------------------------------- > I kindly would like to ask you for confirmation of the problem. > Because i want to exclude that the problem is just due to our system > set-up here. > I would highly appreciate if you could try to re-produce the problem > (see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42791) > and give us positive or negative confirmation.

[Serialization] Runtime error in load_pointer
by elizabeta petreska 19 Jan '10

19 Jan '10

Hello I do not have small working example, and can't reduce the problem to such. I know that is impossible to say what can be the problem from the following information, but still I 'll give it a try. I am getting runtime error in STL ( vector is out of range error ) when trying to load my shared pointer. The runtime error happens in basic_iarchive.cpp line line 431 : cobject_id_vector[i].bpis_ptr = bpis_ptr; I am using boost 1.41. Anyone has seen this error and maybe knows what can get to it. Thanks

Ease of use vs. stability
by Ruediger Berlich 19 Jan '10

19 Jan '10

Hi there, I am using a multitude of different Boost libraries in my code. Since that code is growing quickly, I am increasingly running into bugs which I (sometimes) consider to be on Boost's side. Allowing only selected Boost versions which are known to run fine with my code would allow me to keep that code simpler and thus less error-prone. As my main platform is Linux, however, which usually comes with a given version of Boost (currently often 1.39), my users would be forced to compile Boost themselves, which will mean that they are less likely to start using my code. If I generally allow all Boost versions above a given version, I have to work around known bugs in certain Boost versions, at the expense of code simplicity and thus stability. However, it will be easier for users to adopt my code. Which strategy did you pick for your code ? Kind Regards / Mit freundlichen Gruessen, Ruediger Berlich

[chrono] v0.3 New Stopwatch Feature
by vicente.botet 19 Jan '10

19 Jan '10

Hi, I'm pleased to announce the new version of the Boost.Chrono library. The implementaton is quite stable; the new interface could suffer of some modifications, renaming, ... as far as you submit some proposals. I would request a formal review soon and I will need a review manager. I know that review managers are hard to find, so if you are interested in the library, please the Review Wizards. The library can be downloaded from http://www.boostpro.com/vault/index.php?action=downloadfile&filename=chrono… and the documentation is online on the sandbox http://svn.boost.org/svn/boost/sandbox/chrono/libs/chrono/doc/html/index.ht…. I've tested it with gcc and MSVC. Previoous version of the library have been testted on Mac, but I'm not able to test this platform. Could someone check if there are some regressions on Mac? New Features: * Process cpu clocks * Independent process cpu clocks for real, user, system process CPU time * Global process cpu clock for real, user, system process CPU time * Stopwatch concept measuring elapsed time between different points in time associated to the operations start, stop, suspend and resume. * stopwatch is a model Stopwatch measuring the elapsed time between the start and the stop operations. * stopwatch_accumulator is a model Stopwatch allowing to accumulate several time samples and give the average, ... * Scoped helper classes allowing to pairwise start/stop operations, suspend/resume and resume/suspend a Stopwatch. * Stopwatch Formatter concept * stopwatch formatter "%ds\n" * stopwatch accumulator formatter "%c times, sum%ss, min%ms, max%Ms, mean%as\n" * time formatter "real %rs, cpu %cs (%p%), user %us, system %ss\n" * digital_time decomposition class separating days, hours,minutes,seconds, nanoseconds from any duration class (looking for a better name) * digital_time formatter "%d days(s) %h:%m:%s.%n\n" * stopwatch_reporter is a convenient generic class reporting elapsed time for the Stopwatch concept. * stopclock<Clock> shortcut stopwatch_reporter<stopwatch<Clcok>> * typeof registration for classes duration and time_point Depreceated Features: * The classes process_times, process_clock, process_timer, timer and run_timer are now deprecated as the preceding additions are more generic. However for backward compatibility they are preserved until inclusion of the library in Boost. Next follows the equivalences: timer<> ~ stopwatch<> process_timer ~ stopwatch<process_cpu_clock> run_timer ~ stopclock<> Bug Fixes * Try to correct warning C4251: 'boost::chrono::run_timer::m_format' : class 'std::basic_string<_Elem,_Traits,_Ax>' needs to have dll-interface to be used by clients of class 'boost::chrono::run_timer', by don't including inlines functions using the std::string m_format. For people that doesn't know it yet, Boost.Chrono library provides: * The C++0x Standard Library's common_type. * The C++0x Standard Library's compile-time rational arithmetic. * The C++0x Standard Library's time utilities, including: * Class template duration * Class template time_point * Clocks: * system_clock * monotonic_clock * high_resolution_clock * typeof registration for classes duration and time_point * Process clocks: * process_real_CPU_clocks, capturing real-CPU times. * process_user_CPU_clocks, capturing user-CPU times. * process_system_CPU_clocks, capturing system-CPU times. * process_cpu_clock, tuple-like class capturing at once real, user-CPU, and system-CPU times. * Stopwatches: * stopwatch, capturing elapsed Clock times. * stopwatch_accumulator, capturing cummulated elapsed Clock times. * scoped helper classes allowing to pairwise start/stop operations, suspend/resume and resume/suspend a Stopwatch. * Stopclocks or Stopwatch reporters: * stopwatch_reporter, convenient reporting of models of Stopwatch results. * stopclock<Clock> shortcut of stopwatch_reporter<stopwatch<Clock>> Best regards, _____________________ Vicente Juan Botet Escribá

fusion struct adapt macro, construct the struct from a fusion vector
by Hicham Mouline 19 Jan '10

19 Jan '10

Hello, I have a struct params { ... }; and I have adapted it as a fusion sequence. However I can't construct a params from a boost::fusion::vector<> with the same types. const params p( v ); // v is a fusion::vector with the same type const params p = v; // both failed to compile Do I need to actually write a specific ctor for params? Will it change the result of the adapt macro? Can I iterate with an algorithm over the vector at runtime to assign to p from v? with fusion::for_each() I couldn't write the functor that would let me assign to p. Regards,

[boost.asio] Flush serial port buffers?
by Pascal Kesseli 18 Jan '10

18 Jan '10

Hi everyone My program currently writes some characters to a device connected over the serial interface and subsequently changes the baud rate, followed by sending some more characters. The problem is that the first transfer does not seem to complete before the baud rate switch and thus is sent with the new baud rate, which is not supposed to happen. What I am looking for is something like a flush() before changing the baud rate. Using: boost::asio::write(*port, buffer(buf, size), transfer_all()); does not seem to work. Any suggestions?

Hi all, Were Boost MultiArray and Boost uBLAS designed to be used together? I.e. can I apply linear algebra operations to Boost MultiArrays and get Boost MultiArrays back? If this is impossible / impractical / inefficient, what's the right approach (conversion?). I would be very keen to know your thoughts on this. Many thanks for your help.

[boost][interval containers (itl)] New library release on sourceforge
by Joachim Faulhaber 18 Jan '10

18 Jan '10

Dear boost users, I have developed a library of interval containers called Interval Template Library (ITL). The library, initially developed in an software industrial context, was proposed at the boost developer's list in May 2008, refined according to boost standards, presented at boostcon09 and submitted for a formal review in September 2009. Hartmut Kaiser is now supporting the ITL as review manager. I have uploaded a new release of the core library of interval containers (itl), extensions (itl_xt) and a test tool (validate) for law based automated testings as itl_plus_3_2_1 at the itl's project site at sourceforge: http://sourceforge.net/projects/itl/ Interval_sets and interval_maps of the ITL proved to be very useful in many fields the most important of which is the date and time problem domain. * Interval_sets and interval_maps can be used like the sets or maps of elements. Yet they are much more space and time efficient when the elements occur in contiguous chunks. * Interval containers allow for intersection with interval_sets to work with segmentation. For instance you might want to intersect an interval container with a grid of months and then iterate over those months. * The ITL comes with a universal mechanism of aggregation, that allows to combine associated values in meaningful ways when intervals overlap on insertion. Aggregation results that are difficult to obtain by handwritten algorithms can be computed in an abstract and simple way. * itl::interval_bitset is a self compressing class to represent very large bitsets.

[math][special_functions] Why is cbrt(x) slower than pow(x, 1/3)?
by Tim Odenthal 18 Jan '10

18 Jan '10

Hi! For a (cell) simulation code I have to calculate lots of cubic roots in every timestep. So I tried to improve performance on my first guess, namely pow(x, 1/3) using boost::math::cbrt(). To my astonishment, this is much slower than the original code. I wrote a small test program to check this claim; compiling with g++ (Ubuntu 4.4.1-4ubuntu9) 4.4.1 (-O3) on a Intel Core i7 CPU I get the following timings (averaging the time over 10 trials): average time to compute 5000000 roots with pow(): 0.603 s. average time to compute 5000000 roots with boost::cbrt(): 1.087 s. average time to compute 5000000 roots with improved boost::cbrt(): 1.015 s. average time to compute 5000000 roots with exp(1/3*log()): 0.541 s. My "improved" version allows giving the boost::math::cbrt() method a first guess instead of taking just the value of the number whose root is to be calculated. Actually, the function I called in this instance 5000000 times does a bit more than just calculating the root; I want to calculate the radii of to spheres which overlap so, that their combined volume is equal to the volume of a "mother sphere": /** * @brief calculates the radius of a daughter cell during symmetric division, * assuming the volume of the mother cell is conserved. * * @param MotherRadius radius of mother cell before division * @param Overlap of the two daughter cells, i.e. radius of daughter - * distance from center of daughter to middle-plane of * both cells * * @return for positive overlap returns positive radius, for negative overlap * negative radius **/ double daughterRadiusfOver( double MotherRadius, double Overlap) { // r = 1/2 (2 sqrt(R^6-h^3 R^3)-h^3+2 R^3)^(1/3)+h^2/(2 (2 sqrt(R^6-h^3 R^3)- h^3+2 R^3)^(1/3)) double O3 = Overlap*Overlap*Overlap; double M3 = MotherRadius*MotherRadius*MotherRadius; double step1 = pow(-O3 + 2*sqrt(-O3*M3 + M3*M3) + 2*M3,1.0/3.0);//<-- CUBIC ROOT HERE!!! Change to: // double step1 = boost::math::cbrt(-O3 + 2*sqrt(-O3*M3 + M3*M3) + 2*M3); if ( Overlap < 0 ){ cerr << "Warning in daughterRadiusfOver: Negative overlap given!" <<endl; return -(step1 + Overlap*Overlap/step1)*0.5; } else { return (step1 + Overlap*Overlap/step1)*0.5; } } Why is boost::math::cbrt() no improvement for me - or am I using it the wrong way? For which cases might it be an improvement, or why is it in the library? It's funny, but I found that std::exp(1/3*std::log(x)) is so far the fastest way... Thanks in advance Tim

[filesystem] boost 1.41, hpux, gcc 440, compilation error solved
by Rui Pedro Fernandes 15 Jan '10

15 Jan '10

Hi, While trying to compile filesystem under HPUX because the WCHAR_MAX define value used was including a ')' character (because the value has a cast). The include file wchar.h defines the correct WCHAR_MAX if macro _INCLUDE_STDC__SOURCE_199901 is defined. I then solved the problem by changing the filesystem's Jamfile.v2 to add the lines: : requirements <host-os>hpux,<toolset>gcc:<define>_INCLUDE_STDC__SOURCE_199901 Don't know however if this is the best way to solve the issue... Thanks, Rui

[serialization] boost 1.33.1, HP-UX ia64 & gcc-3.4.4
by Frank Bergemann 15 Jan '10

15 Jan '10

Hi, for a porting job i needed to shift from OSF tru64 to HP-UX V3 ia64 (on both using gcc-3.4.4) There i have stream error exception for boost::serialization data import via XML. The exception is thrown here: include/boost/archive/impl/basic_xml_iarchive.ipp: template<class Archive> BOOST_ARCHIVE_OR_WARCHIVE_DECL(void) basic_xml_iarchive<Archive>::load_start(const char *name){ // if there's no name if(NULL == name) return; bool result = this->This()->gimpl->parse_start_tag(this->This()->get_is()); if(true != result){ boost::throw_exception( archive_exception(archive_exception::stream_error) ); } // don't check start tag at highest level ++depth; return; } I.e. it fails to parse the XML data via boost:spirit. I tried to debug with 'gdb', but was impossible for me at the level of boost::spirit parser implementation. Then i was remembering, that there are two sets of boost libs - one "normal" and a "debug" version. So i switched to the debug version - just to see, if i can better dig into the details with 'gdb' with it. And suddenly the problem was gone. I.e. my application works, if i link with libboost_serialization-gcc-d.a But it doesn't work, if i link with libboost_serialization-gcc.a I also tried to extract all the stuff from the boost::serialization, that is used by my application, into a little test program. Just to feed in the same XML string, that fails for my application. I wanted to see, that i can re-produce the problem - but for a minimum program. - for using that next to evaluate deeper. But - unfortunately - for my test programm it works (with both library versions, "debug" and "normal" one). So it is really hard to find the reason for the problem. I also checked about compiler support on the boost.org pages. And actually it was only boost lib 1.38.0, which mentions HP-UX IA64 together with gcc. But that was gcc-4.2.1 (i use 3.4.4.). Before 1.38.0, it was alway the HP native compiler (not gcc). After 1.38.0 HP-UX is not mentioned at all anymore. So i guess i am generally in bad conditions for my "constellation" (HP-UX ia64 V3, gcc-3.4.4, boost 1.33.1). What is the difference about "debug" lib image and "non-debug" lib image? Is it just optimization level for the compiler? Do you have any hint for me? It might be a problem of gcc-3.4.4 itself on hp-ux (i'll check). But it would be interesting to here, if s.o. else had the same problem(?!) - many thanks!

How to use boost-build/bjam with only home directory acces?
by s seelenluft 15 Jan '10

15 Jan '10

Hi, I have successfully installed boost-build and bjam on a Linux workstation where I only had access to my home folder, but I have trouble replicating this on another. I put the boot-build folder at the top level of my home folder and created also a bin folder there into which I copied the content of boost-build folder and the bjam binary. I then added an environmental variable BOOSTROOT with the value '../' and set my jamroot file to <include>$BOOSTROOT. I can now start bjam from folders one level below the home folder. On a different Linux system this fails with the error: Unable to load Boost.Build: could not find "boost-build.jam" --------------------------------------------------------------- Attempted search from /afs/.../trunk-1 up to the root and in these directories from BOOST_BUILD_PATH and BOOST_ROOT: /usr/share/boost-build. Please consult the documentation at 'http://www.boost.org'. The boost-build.jam file sits in the same folder as bjam (~/bin) but on one system bjam finds it and on another it does not. The folder /usr/share/boost-build does not exist and I do not have the permission to create it. I've used boost-jam 3.1.13 on both systems (since it worked fine on one system, I was loth to change anything). This was the current version when I started the whole business. In short: Is there any way to tell bjam to use the local boost-build.jam file? Thanks. Markus

[karma] using attributes out of order
by Cory Nelson 15 Jan '10

Hello, I was fairly familiar with Spirit 1, but I'm now making my first foray into Spirit 2. I'm trying to write something with karma's attribute system. Say I've got a fusion adapted struct: struct s { int foo; double bar; std::string baz; }; The Spirit docs give plenty of examples like: int_ << double_ << string But I can't find any docs showing how to output the members in a different order, like: double_ << string << int_ Is there a recommended way to achieve this? Thanks! -- Cory Nelson

BoostJam sensitive to spaces in paths, in particular in TMP
by Bilokon, Paul 15 Jan '10

15 Jan '10

Hi all, Just found this, apparently a bug, in BoostJam. I'm using an admittedly old version of Boost, V1.36.0, in this particular instance. I'm using the latest BoostJam, V3.1.17. This occurs on Windows when the TMP environment variable contains spaces. In my case it was "C:\Documents and Settings\xxxxxxxxxxx\Local Settings\Temp" When you try to run something like C:\Programs\Win32\BoostJam\V3.1.17\bjam.exe --build-type=complete --toolset=msvc-90 --with-thread You get MkDir1-quick-fix-for-windows bin.v2\libs\thread 'C:\Documents' is not recognized as an internal or external command, operable program or batch file. if not exist "bin.v2\libs\thread\\" mkdir "bin.v2\libs\thread" ...failed MkDir1-quick-fix-for-windows bin.v2\libs\thread... This is fixed by set TMP=C:\temp I don't know if this merits a patch.

read_graphviz in 1.4x series
by Cyrus Hall 15 Jan '10

15 Jan '10

Ciao all- I've been happily using the boost graph library for a number of months now. Thanks to everyone who has contributed to this great piece of software. After upgrading from boost 1.38 to 1.40 in Ubuntu, read_graphviz now prints to std::cerr the graph it has just read. I downloaded to the source code to make sure this wasn't some cruft left over by the Ubuntu package managers, and it seems these print statements are in the main distribution package. This change seems to correspond with a complete rewrite of the scanning and parsing underlying read_graphviz, which seems to have happened between 1.39 and 1.40. 1.41 contains no changes from 1.40 in read_graphviz_new.cpp. The particular offending lines of code are in translate_results_to_graph in read_graphviz_new.cpp, starting at line 760. This is called directly from detail::graph::read_graphviz on line 796. I see no obvious way to toggle these print statements. But I also can't find other messages about this problem, so I'm guessing I'm just missing something. Is there someway I can get read of this debugging output? Cheers, Cyrus

Windows: Mixed .NET and native C++ with Boost
by Richwin, Dr. Matthias 15 Jan '10

15 Jan '10

Hi all, I try the following scenario: - a C++ library (my own code), unmanaged, makes use of boost (e.g. regex) - a C++ .NET application (windows forms based) planned as GUI (having used Borland C++ builder in the past, the windows forms approach looks quite appealing to me) - my C++ library header is included in the .Net form header file wrapped in a #pragma unmanaged/managed pair. I compiles and links well. For simple test purposes, I instantiate a class from my C++ library in the form constructor. Calling some unmanaged code from my library there creates a debug assertion: "Debug Assertion Failed!

[multiarray] problems passing views by reference
by Rhys Ulerich 14 Jan '10

14 Jan '10

Recently, Hanan Sadar asked about a multi_array fill implementation [1]. The standard std::fill_n(x.data(),x.num_elements(),v) answer only works when x is a boost::multi_array or boost::multi_array_ref but does not handle the general MultiArray concept. I decided to implement an arbitrary dimensional MultiArray fill capable of handling such views correctly. It's been absolutely miserable for reasons I don't understand but which resemble comments from James Amundson's recent thread [2]. Attached is my attempt with two exasperating lines marked by "Cannot use reference, why?". For a non-multi_array, non-multi_array_ref instance (i.e. a view) using a signature like template< class Array, class V > void operator()(Array x, const V &v); allows the code to compile and operate correctly. However, it incurs pass-by-value overhead. Using a signature like template< class Array, class V > void operator()(Array &x, const V &v); using pass-by-reference dies at compilation time. All of my attempts to use MultiArray's associated typedefs die, including hours of mucking with MultiArray::reference. What am I missing here? Why can't I pass a general MultiArray view type by reference? - Rhys [1] http://groups.google.com/group/boost-list/browse_thread/thread/829ebea7fef2… [2] http://groups.google.com/group/boost-list/browse_thread/thread/4531a7c35a58…

boost python macro hell

Probably OT, but I'm trying to generate modules programmatically. Each module with be generated using -DSIMCASE=n and will create a module called ldpc_n.so. I can't get this macro to work, this is my latest try: #define SIMCASE 10 #define NAME ldpc_ ## SIMCASE #define MODULE_START BOOST_PYTHON_MODULE (NAME) Later I have: MODULE_START { ... } Results in: In file included from ldpc_x.cc:12: ldpc.cc: In function 'void initldpc_SIMCASE()': ldpc.cc:100: error: 'init_module_ldpc_SIMCASE' was not declared in this scope Looks like 2 problems there: 1 is that 'SIMCASE' did not have it's #defined value substituted, second is that (as evidenced by the error) this interacted wierdly with the BOOST_PYTHON_MODULE macro.

hi everybody, i have an issue with my asio-client that wants to connect to an asio-server. when i set my server on a machine in our network to listening on a port (>1024) and then try to connect with my client via this port, i get a "Connection refused"-exception. this happens every time the server and client are located on different machines. if i try this on the same machine it works fine! also, if i try to connect via telnet from another machine it works! here's the client-setup-code snippet, maybe i missed a special config there?: tcp::resolver resolver( _io ); //_io is class-member tcp::resolver::query query( server, port ); //server and port are char-buffers tcp::resolver::iterator iter = resolver.resolve( query ); _socket = new tcp::socket( _io ); tcp::resolver::iterator end; // End marker. boost::system::error_code error = error::host_not_found; while (error && iter != end) { _socket->close(); _socket->connect(*iter++, error); } if (error) throw boost::system::system_error( error ); } catch( std::exception& e ) { cout << "NetClient Konstruktor: " << e.what() << endl; }

The setters are being called correctly, but the data is not getting through for some reason. It's like the data structure is being copied instead of referenced but I'm explicitely using references. Any idea what gives?

Building 1.41 for win64 with python
by Tom Kent 13 Jan '10

I googled around for this, but didn't find any answers. I'm building 64 bit libraries for visual studio on a 32 bit win XP box and getting the attached linker errors. I get similar results with visual studio 8 and 9. Any thoughts?

by victor 13 Jan '10

13 Jan '10

I call boost::asio::async_write, finally it call "bool enqueue_operation(Descriptor descriptor, Operation operation)" In this function , there is code as flow: while (current_op->next_) current_op = current_op->next_; My process execute it for ever. Using gdb to attach the prcocess, I find : 68 while (current_op->next_) (gdb) p current_op $8 = (class boost::asio::detail::reactor_op_queue<int>::op_base *) 0x93381c8 (gdb) p current_op->next_ $9 = (class boost::asio::detail::reactor_op_queue<int>::op_base *) 0x93381c8 current_op and current_op->next_ is the same address. how did it come true? I have no any clue. Anyone can offer some suggestion?

Newbie question: Serialization of an Array2D --> Cell** m_cells
by Simon Ruffieux 13 Jan '10

13 Jan '10

Hello ! I am trying to serialize a a complex structure. One of the "variable" is a 2D Array (Cell** m_cells ) declared with pointers. I need to keep this data structure as it is. I have read some stuff about multi array with boost but found nothing to serialize my Cell** m_cells. Maybe one of you has the solution .... Note1: using boost 1.41.0, g++ and ubuntu 9.04 .... Note2: As you may understand while reading the code, I have in fact an Array2D of PointAccumulator .... (Cell = PointAccumulator) The part of code that is not correct ..... * template <class Archive> void serialize(Archive& ar, const unsigned int version){ *ar & m_xsize & m_ysize &* m_cells; }* And raising this error: wheelchair@wheelchair-laptop:~/playerstage/boostTest$ g++ -I/usr/local/include/ -L/usr/local/lib/ simple2.cpp -o simple -lboost_serialization /usr/local/include/boost/serialization/access.hpp: In static member function ‘static void boost::serialization::access::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::text_iarchive, T = PointAccumulator*]’: /usr/local/include/boost/serialization/serialization.hpp:74: instantiated from ‘void boost::serialization::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::text_iarchive, T = PointAccumulator*]’ /usr/local/include/boost/serialization/serialization.hpp:133: instantiated from ‘void boost::serialization::serialize_adl(Archive&, T&, unsigned int) [with Archive = boost::archive::text_iarchive, T = PointAccumulator*]’ /usr/local/include/boost/archive/detail/iserializer.hpp:173: instantiated from ‘void boost::archive::detail::iserializer<Archive, T>::load_object_data(boost::archive::detail::basic_iarchive&, void*, unsigned int) const [with Archive = boost::archive::text_iarchive, T = PointAccumulator*]’ simple2.cpp:186: instantiated from here /usr/local/include/boost/serialization/access.hpp:109: error: request for member ‘serialize’ in ‘t’, which is of non-class type ‘PointAccumulator*’ /usr/local/include/boost/serialization/access.hpp: In static member function ‘static void boost::serialization::access::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::text_oarchive, T = PointAccumulator*]’: /usr/local/include/boost/serialization/serialization.hpp:74: instantiated from ‘void boost::serialization::serialize(Archive&, T&, unsigned int) [with Archive = boost::archive::text_oarchive, T = PointAccumulator*]’ /usr/local/include/boost/serialization/serialization.hpp:133: instantiated from ‘void boost::serialization::serialize_adl(Archive&, T&, unsigned int) [with Archive = boost::archive::text_oarchive, T = PointAccumulator*]’ /usr/local/include/boost/archive/detail/oserializer.hpp:139: instantiated from ‘void boost::archive::detail::oserializer<Archive, T>::save_object_data(boost::archive::detail::basic_oarchive&, const void*) const [with Archive = boost::archive::text_oarchive, T = PointAccumulator*]’ simple2.cpp:186: instantiated from here /usr/local/include/boost/serialization/access.hpp:109: error: request for member ‘serialize’ in ‘t’, which is of non-class type ‘PointAccumulator*’ Here is the code I use for my tests: #include <iostream> #include <iterator> #include <algorithm> #include <sstream> #include <fstream> #include <boost/archive/text_oarchive.hpp> #include <boost/archive/text_iarchive.hpp> using namespace std;

newbie question --> invalid application of ?sizeof? to incomplete type ?boost::STATIC_ASSERTION_FAILURE<false>?

Hello ! I am a newbie to Boost ... and trying to use it in order to serialize a complex data structure for one of my project. (the struct particle) You can see the nested data structure at the end of this file. I have started from the 'leafs' and yet trying to serialize a point which is a variable of a PointAccumulator. You can see the point.h file below. Here is the test code I am using to try to serialize it. Note that I read a few succinct tutorials and already succesfully compiled some simple examples. ... GMapping::point<int>p = GMapping::point<int>(); //saveIntoFile<text_oarchive>(particlesSaved[1].map.cell(1,1).acc, "outTest.txt"); saveIntoFile<text_oarchive>(p, "outTest.txt"); ... template <class T> void RobotController::saveIntoFile(GMapping::point<int>& p, const char* file){ std::ofstream ofile(file); T ar(ofile); ar << p; ofile.close(); } However when compiling; it raises the following error: ... /usr/include/boost/archive/detail/oserializer.hpp: In function ‘void boost::archive::save(Archive&, T&) [with Archive = boost::archive::text_oarchive, T = GMapping::point<int>]’: /usr/include/boost/archive/detail/common_oarchive.hpp:64: instantiated from ‘void boost::archive::detail::common_oarchive<Archive>::save_override(T&, int) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/basic_text_oarchive.hpp:75: instantiated from ‘void boost::archive::basic_text_oarchive<Archive>::save_override(T&, int) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/detail/interface_oarchive.hpp:64: instantiated from ‘Archive& boost::archive::detail::interface_oarchive<Archive>::operator<<(T&) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ RobotController.cpp:186: instantiated from ‘void RobotController::saveIntoFile(GMapping::point<int>, const char*) [with T = boost::archive::text_oarchive]’ RobotController.cpp:223: instantiated from here /usr/include/boost/archive/detail/oserializer.hpp:564: error: invalid application of ‘sizeof’ to incomplete type ‘boost::STATIC_ASSERTION_FAILURE<false>’ /usr/include/boost/archive/detail/common_oarchive.hpp:64: instantiated from ‘void boost::archive::detail::common_oarchive<Archive>::save_override(T&, int) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/basic_text_oarchive.hpp:75: instantiated from ‘void boost::archive::basic_text_oarchive<Archive>::save_override(T&, int) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ /usr/include/boost/archive/detail/interface_oarchive.hpp:64: instantiated from ‘Archive& boost::archive::detail::interface_oarchive<Archive>::operator<<(T&) [with T = GMapping::point<int>, Archive = boost::archive::text_oarchive]’ RobotController.cpp:186: instantiated from ‘void RobotController::saveIntoFile(GMapping::point<int>, const char*) [with T = boost::archive::text_oarchive]’ RobotController.cpp:223: instantiated from here /usr/include/boost/archive/detail/oserializer.hpp:564: error: invalid application of ‘sizeof’ to incomplete type ‘boost::STATIC_ASSERTION_FAILURE<false>’ make: *** [RobotController.o] Error 1 Anyone understands what is the error ?

Hi to all, i wrote a class (Influx), where i try to define there a boost::multi_arry occ_sign_change. Once i tried in Influx::Influx to write: occ_sign_change = vec::uint32_1d_t ( boost::extents[ num_elements ] ); i was able to compile, but at run time i got the following error: randum.rc3_64: /usr/include/boost/multi_array/multi_array_ref.hpp:487: boost::multi_array_ref<T, NumDims>& boost::multi_array_ref<T, NumDims>::operator=(const ConstMultiArray&) [with ConstMultiArray = boost::multi_array<unsigned int, 1ul, std::allocator<unsigned int> >, T = unsigned int, long unsigned int NumDims = 1ul]: Assertion `std::equal(other.shape(),other.shape()+this->num_dimensions(), this->shape())' failed. that is why i rewrote the above line as following: vec::uint32_1d_t occ_sign_change ( boost::extents[ num_elements ] ); but now, when i call for the size of occ_sign_change in Influx::Clean, i get that the size is zero. how could i solve this problem? regards #include <boost/random/uniform_01.hpp> #include <boost/random.hpp> #include "randum.rc3.hpp" namespace vec { typedef boost::multi_array< uint32_t , 1> uint32_1d_t; typedef boost::multi_array< uint32_t , 2> uint32_2d_t; typedef boost::multi_array< uint32_t , 3> uint32_3d_t; typedef boost::multi_array< uint32_t , 1> uint32_1d_t; typedef boost::multi_array< uint32_t , 2> uint32_2d_t; typedef boost::multi_array< double , 1> double_1d_t; typedef boost::multi_array< double , 2> double_2d_t; typedef uint32_1d_t::index index_t; } class Influx { public: Influx ( uint32_t num_elements , double p_, double kappa_ , vec::uint32_2d_t *Pointer_ , threshold_t threshold_ , uint32_t num_bits , uint16_t max_runs_ ); void Update (); void Validity ( const uint32_t i ); void Clean( uint32_t run ); boost::dynamic_bitset<> occupied; vec::uint32_1d_t occupied_counter; vec::uint32_1d_t num_neighbours; vec::uint32_1d_t occ_sign_change; private: std::vector< uint32_t > remove_node_v; vec::uint32_2d_t *Pointer; std::vector< uint32_t > num_neighbours_epoch; double p; double kappa; threshold_t threshold; uint16_t max_runs; uint32_t bits_mask; uint32_t complement_num; }; Influx::Influx ( uint32_t num_elements , double p_, double kappa_ , vec::uint32_2d_t *Pointer_ , threshold_t threshold_ , uint32_t num_bits , uint16_t max_runs_ ) { bits_mask = ( 1 << num_bits ) - 1; Pointer = Pointer_; p = p_; kappa = kappa_; threshold = threshold_; max_runs = max_runs_; complement_num = 0; num_neighbours_epoch = std::vector< uint32_t > ( num_elements , 0); occupied = boost::dynamic_bitset<> ( num_elements , 0 ); // all 0's by default vec::uint32_1d_t occupied_counter ( boost::extents[ num_elements ] ); vec::uint32_1d_t occ_sign_change ( boost::extents[ num_elements ] ); vec::uint32_1d_t num_neighbours ( boost::extents[ num_elements ] ); remove_node_v.reserve( num_elements ); std::fill_n( occupied_counter.begin() , occupied_counter.num_elements() , 0 ); std::fill_n( occ_sign_change.begin() , occ_sign_change.num_elements() , 0 ); std::fill_n( num_neighbours.origin() , num_neighbours.num_elements() , 0 ); } void Influx::Clean ( uint32_t run ) { for ( vec::uint32_1d_t::size_type i = 0 ; i < remove_node_v.size() ; i++ ) { occupied[ remove_node_v[i] ] = 0; if ( run >= max_runs ) { std::cout << "size occ_sign_change: " << occ_sign_change.size() << std::endl; occ_sign_change[ remove_node_v[i] ]++; } } remove_node_v.clear(); }

[asio] Why are the strands in the "HTTP Server 3" example necessary?
by Tacheon 12 Jan '10

12 Jan '10

In the HTTP Server 3 (http://tinyurl.com/yh95d2b) example of the asio documentation strands are used to synchronize the invocation of completion handlers? But why are they necessary here? As far as I get it, the handlers are invoked in strict sequential order for each distinct connection (http://tinyurl.com/ybohynd) Each connection has its own set of resources so synchronization shouldn't be necessary, should it? Thanks in advance, Boris

gil and OpenGL
by mailinglist＠squarepx.com 12 Jan '10

12 Jan '10

This is my first post in any mailinglist ever so i hope i am doing this right. I successfully integrated the boost::gil module into my code to load some images and process their content so that I can display it as a texture in OpenGL. My problem right now is the massive performance issue in retrieving the color information from the loaded image. I am looping through every row and column and retrieve the red, green, blue and alpha color with the get_color method and push those values to a char array. So I was wondering what the best approach would be to get the color information from the gil image into OpenGL or at least a char array. Thanks in advance.

Hi, Using Visual Studio, it is possible to 'Ignore Specific Library' (Project Properties>Configuration Properties>Linker>Input>Ignore Specific Library). We have found this a useful feature in a project. Now we want to build the project using bjam, but we need to reproduce that linker behaviour. Is there any ignore <library> feature? Many thanks Simon

how to make Pool allocate one chunk buffer one time?
by zhangxiaowei 12 Jan '10

12 Jan '10

Hi, all I am doing one video processing software, which uses Boost::pool as the buffer manager. but every time pool allocates buffers, it malloc all needed memory at one time. for example, I create one pool object for 1024 B for one chunk, and 16 chunks at first. Pool malloc all the 1024 * 16 (16KB) at one time. this leads to memory allocation error for my application, because I need 8294400B (1920 * 1080 * 4, for one video frame) * 32, that is more than 256 MB. I use default new/delete, so new returns NULL for the third time in my case. but from memory monitor, there are still enough memory free. after tracing into new, I found this is from the Microsoft memory management design and memory fragments. is there any way to set Pool to allocate one chunk by another? for example, when I want one chunk, it allocates 8294400B. and for another time, it does another. so this should solve my issues for the memory usage. after checking the code of Pool, it is all based on contiguous memory. if pool cannot meet my requirement, is there any other option in BOOST? BTW, I am working on Windows 32 bits with MS Visual Studio 2005. Thank you for any comment.

utf8_codecvt_facet
by Patrick Horgan 11 Jan '10

11 Jan '10

utf8_codecvt is in libserialization and in libprogram_options--I thought it was moving to utility? Is there one supported spot? Is there any documentation that talks about what to include and link? The .hpp file is still in boost/detail, boost/archive/detail, boost/program_options,boost_filesystem/src, and libs/iostreams/test/detail. Guess it's not cleaned up yet? Or maybe people didn't want cross dependencies? Anyway I need to either use it or write one;) I'm not doing serialization or program_options (yet, who knows, just starting the project). I also need to be able to be able to deal with UTF-16, I don't suppose there's a codecvt facet for that, huh? Patrick

Using 'address-model-32_64' on Mac OS 10.6
by Dane Springmeyer 11 Jan '10

11 Jan '10

I've recently upgraded to a Mac with 64bit firmware and Snow Leopard. I've noticed all applications compiled with g++ now default to 64 bit libs (x86_64), including boost. Thanks by the way for the fixes to boost 1.41 that allow successful 3- way arch compilation on osx again! Now I'm trying to just build two- way arches. I'm now trying to compile boost (I happen to be using trunk), and am noticing that passing 'address-model-32_64' does not seem to have the effect I'd expect. If the flag is passed the only affect I notice is that the build directories include it 'address-model-32_64' in the path, but notably the '-arch -i386 -arch x86_64' flags are not properly added to the CXXFLAGS and LINKFLAGS. Therefore the compiled dynamic libraries are still single architecture, x86_64. Passing 'architecture=combined' does prompt these flags, but includes the 'arch ppc' flag as well which I don't want. So, is it a bug that using address-model alone does not work or am I am misunderstanding something? Thanks for any clarification. Cheers, Dane

Problem iterating over vertices (Property Map!?)
by Pedram Pedarsani 11 Jan '10

11 Jan '10

I am kind of new to C++ and also BGL, so it'll be great if you can help me with this problem! I'm iterating over all the vertices of my graph, and each time I iterate, I want to *mark* a vertex (which has some specific degree for example, or some other property that I can calculate), so as not to iterate over it the next time. I'll do this process until all vertices are marked, so no more iteration. For now, what I'm doing is putting the marked vertices in a separate list, and each time I iterate over all vertices again and I check whether each vertex is in the marked list (which is very inefficient). Could you please help me with an efficient way of doing this? I was thinking to use Property Map but I have no idea how! Any small piece of code will be appreciated. Thanks a lot!

BGL: shared_ptr as bundled properties > how to generate properties maps ???
by Damien Maupu 11 Jan '10

11 Jan '10

Dear all, I am using bundled properties when I define my graph. The bundled properties are smart pointers to my own class Edge and Vertex. I write something like: typedef boost::shared_ptr<Vertex> VertexPtr; typedef boost::shared_ptr<Edge> EdgePtr; typedef adjacency_list<vecS, vecS, directedS, VertexPtr, EdgePtr> Graph; Vertex and Edge being my own classes to store information on the vertices and the edges. For what I read in the doc, this is the correct, more modern way to do it. My problem is the following. I am trying to use the BGL algorithms and some of them require vertex/edge info to be provide as properties maps. From http://www.boost.org/doc/libs/1_41_0/libs/graph/doc/bundles.html I know it is possible to generate those maps from bundled properties. It works well if I don't use shared_ptr but cannot compile otherwise. When using shared_ptr, similarly to the doc, I wrote: typedef property_map<SearchGraph, float EdgePtr::*>::type WeightMap; WeightMap weightMap = get(&EdgePtr::m_cost, *_graph); m_cost being a public float member of my own class Edge. I have the following compilation error: 'm_cost' : is not a member of 'boost::shared_ptr<T>' Indeed it is not. My question is, I can let the shared_ptr access the member? In other world how to deal with bundled properties / properties maps and shared_ptr. Extra question, could 'm_cost' be a private member of my own class Edge? Thank you very much Sincerely, Damien

can serialize multi-class into a single Archive?
by pengdw 11 Jan '10

11 Jan '10

I want to serialize multiple class into a single file. that's: class object {}; ofstream ofs; ofs.open("data.txt"); boost::archive::text_oarchive oa(ofs); while (get_next_object(object_t obj)) { oa << obj; } It is ok when I use text_iarchive to read back these objects. Now I want to append some objects to a Archive, I need to reopen the data file "data.txt" with (ios_base::app | ios_base::out), and serialize some object to the new-opend Archive. then when I use text_iarchive to load, I got error messages. I checked some manuals, and use boost::archive::no_header to skip the archive headers like "22 serialization::archive" when appending objects. but still I got error messages when loading. can anyone tell me how to store and append objects to a single Archive, and load correctly. tks.

[repost][serialization] version handling in {save|load}_construct_data
by JOAQUIN M. LOPEZ MUÑOZ 11 Jan '10

11 Jan '10

Hello, allow me to repost this message from a couple of weeks ago: I've taken a look at how the version number is dealt with in Boost.Serialization collection serialization code: * The relevant code at saving time is: if(3 < ar.get_library_version()){ const unsigned int item_version = version< BOOST_DEDUCED_TYPENAME Container::value_type >::value; ar << BOOST_SERIALIZATION_NVP(item_version); } * At loading time, the equivalent code is: unsigned int item_version; ar >> BOOST_SERIALIZATION_NVP(count); if(3 < ar.get_library_version()) ar >> BOOST_SERIALIZATION_NVP(item_version); else item_version = 0; Can someone (aka Robert :-) ) shed some light on this bit? Why the version number has to be given such manual processing when this is not needed if, for instance, serializating values via the simple ar&value? I'm trying to do the equivalent thing in Boost.MultiIndex. Thank you, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

I'm afraid that does not entirely answer my question. I understand what the "if(3 < ar.get_library_version()){" guard is for. What puzzles is me is why you need to explicitly save the type serialization version number when this info is seemingly recovered in other contexts without any explicit user operation. Let me put it another way: consider a user defined type my_type with associated serialization code: template<class Archive> void serialize(Archive& ar,my_type & m,const unsigned int version) { ... } When serialize() is called internally by Boost.Serialization, version is correctly passed without the user explicitly saving this info as it happens in the code for collection serialization. Why this difference? Am i making myself clear as to what the root of my puzzlement is? Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

[BGL] dijkstra_shortest_paths with listS
by gast128 09 Jan '10

09 Jan '10

Hello all, BGL supports a lot of graph algorithms, and lots of stuff get default filled in when using vecS as container type of vertices. However things become pretty ugly when not using this container. Below I used a listS for both edges and vertices. Maybe it can help other people (and maybe somebody can cross check me). Note that some constructs could be bundled, but for clearity I explicitly wrote all things out. I use the graph from the BGL book as example (figure 13.3). void TestgraphDijkstra() { typedef boost::adjacency_list<boost::listS, boost::listS, boost::bidirectionalS, std::string> Graph; typedef boost::graph_traits<Graph>::vertex_descriptor VertexDescriptor; typedef boost::graph_traits<Graph>::edge_descriptor EdgeDescriptor; typedef int Weight; typedef std::map<EdgeDescriptor, Weight> WeightMap; typedef std::map<VertexDescriptor, size_t> VertexIndexMap; typedef std::map<VertexDescriptor, Weight> DistanceMap; typedef std::map<VertexDescriptor, VertexDescriptor> PredecessorMap; Graph graph; WeightMap mapWeigth; VertexIndexMap mapVertexIndex; DistanceMap mapDistance; PredecessorMap mapPredecessor; boost::associative_property_map<WeightMap> pmWeigth(mapWeigth); boost::associative_property_map<VertexIndexMap> pmVertexIndex (mapVertexIndex); boost::associative_property_map<DistanceMap> pmDistance(mapDistance); boost::associative_property_map<PredecessorMap> pmPredecessor (mapPredecessor); //build a graph according to figure 13.3 //add vertices const VertexDescriptor vA = boost::add_vertex(graph); const VertexDescriptor vB = boost::add_vertex(graph); const VertexDescriptor vC = boost::add_vertex(graph); const VertexDescriptor vD = boost::add_vertex(graph); const VertexDescriptor vE = boost::add_vertex(graph); //set vertex names graph[vA] = "A"; graph[vB] = "B"; graph[vC] = "C"; graph[vD] = "D"; graph[vE] = "E"; //add edges const EdgeDescriptor eAC = boost::add_edge(vA, vC, graph).first; const EdgeDescriptor eBB = boost::add_edge(vB, vB, graph).first; const EdgeDescriptor eBD = boost::add_edge(vB, vD, graph).first; const EdgeDescriptor eBE = boost::add_edge(vB, vE, graph).first; const EdgeDescriptor eCB = boost::add_edge(vC, vB, graph).first; const EdgeDescriptor eCD = boost::add_edge(vC, vD, graph).first; const EdgeDescriptor eDE = boost::add_edge(vD, vE, graph).first; const EdgeDescriptor eEB = boost::add_edge(vE, vB, graph).first; const EdgeDescriptor eEA = boost::add_edge(vE, vA, graph).first; //set edge weights boost::put(pmWeigth, eAC, 1); boost::put(pmWeigth, eBB, 2); boost::put(pmWeigth, eBD, 1); boost::put(pmWeigth, eBE, 2); boost::put(pmWeigth, eCB, 7); boost::put(pmWeigth, eCD, 3); boost::put(pmWeigth, eDE, 1); boost::put(pmWeigth, eEB, 1); boost::put(pmWeigth, eEA, 1); //build index map boost::put(pmVertexIndex, vA, 0); boost::put(pmVertexIndex, vB, 1); boost::put(pmVertexIndex, vC, 2); boost::put(pmVertexIndex, vD, 3); boost::put(pmVertexIndex, vE, 4); //note: color map not needed, because of index map? boost::dijkstra_shortest_paths(graph, vA, boost::weight_map (pmWeigth).vertex_index_map(pmVertexIndex).distance_map (pmDistance).predecessor_map(pmPredecessor)); for (DistanceMap::const_iterator itDist = mapDistance.begin(); itDist != mapDistance.end(); ++itDist) { //dump const VertexDescriptor v = itDist->first; const VertexDescriptor vPrev = mapPredecessor[v]; std::cout << "Distance(" << graph[v] << ") = " << itDist->second << ", " << "Parent(" << graph[v] << ") = " << graph[vPrev] << std::endl; } }
