multi_index_container and templates
by Andrej van der Zee 13 Jun '07

13 Jun '07

Hi, I am trying to set up a multi_index_container-type with a template argument like this: template <typename event_type> struct mi_container { typedef typename mi::composite_key< event_type, mi::const_mem_fun<fields::field_ts, ts_type, &fields::field_ts::ts>, mi::const_mem_fun<fields::field_addr, addr_type, &fields::field_addr::addr>, mi::const_mem_fun<fields::field_port, port_type, &fields::field_port::port> > self_key_type; typedef typename mi::composite_key< event_type, mi::const_mem_fun<fields::field_ts, ts_type, &fields::field_ts::ts>, mi::const_mem_fun<fields::field_peer_addr, addr_type, &fields::field_peer_addr::peer_addr>, mi::const_mem_fun<fields::field_peer_port, port_type, &fields::field_peer_port::peer_port> > peer_key_type; typedef typename mi::multi_index_container< event_type, mi::indexed_by< mi::ordered_non_unique< mi::tag<self_key_tag>, self_key_type>, mi::ordered_non_unique< mi::tag<peer_key_tag>, peer_key_type> > > type; }; mi_container<ev_connect>::type connected; This gives me the following compile-error: main.cpp: In instantiation of mi_container<event::ev_connect>: main.cpp:78: instantiated from here main.cpp:57: error: invalid use of event::fields::field_ts::ts to form a pointer-to-member-function main.cpp:57: note: a qualified-id is required main.cpp:64: error: invalid use of event::fields::field_ts::ts to form a pointer-to-member-function main.cpp:64: note: a qualified-id is required main.cpp:75: error: invalid use of event::fields::field_ts::ts to form a pointer-to-member-function main.cpp:75: note: a qualified-id is required Probably I doing something silly. Note that if I remove the class template and directly specialize it, there is no problem at all. Can anybody help me out?

[asio] http-server example
by Daniel Albuschat 13 Jun '07

13 Jun '07

Hello there, I'm currently building my own, specialized http-server based on the http-server example. I experience crashes for certain types of replies. Here's something I really do not understand: In connection.cpp, after request_parser_.parse() finished and result == true, there is this line: boost::asio::async_write(socket_, reply_.to_buffers(), boost::bind(&connection::handle_write, shared_from_this(), boost::asio::placeholders::error)); It's the last user-code in the stacktrace of the crash that I frequently experience. What bothers me is the reply_.to_buffers() function. It looks like this: std::vector<boost::asio::const_buffer> reply::to_buffers() { std::vector<boost::asio::const_buffer> buffers; buffers.push_back(status_strings::to_buffer(status)); for (std::size_t i = 0; i < headers.size(); ++i) { header& h = headers[i]; buffers.push_back(boost::asio::buffer(h.name)); buffers.push_back(boost::asio::buffer(misc_strings::name_value_separator)); buffers.push_back(boost::asio::buffer(h.value)); buffers.push_back(boost::asio::buffer(misc_strings::crlf)); } buffers.push_back(boost::asio::buffer(misc_strings::crlf)); buffers.push_back(boost::asio::buffer(content)); return buffers; } How can this even work? It adds temporaries (the misc_strings are const char[]s) to a const_buffer-vector and reads them later. Even the references to h.name, etc. seem invalid to me, since the io is asynchronous and there's no guarantee that they don't change. IMHO the whole content needs to be COPIED to new buffers and then, after the async_write finished, deleted. Am I missing something? Was the author of this example not aware of the const_buffer's ownership policy (i.e. it is *not* owner of the data)? I've spent hours and hours in debugging now, but I just can't figure out where it goes wrong. You can see the stacktrace here: http://mandrill.fuxx0r.net/c++/paste:7702 Kind regards, Daniel Albuschat -- eat(this); // delicious suicide

[asio] file streaming
by Chris Fairles 13 Jun '07

13 Jun '07

I give up! I cannot for the life of me figure out buffers and streams. Any help is greatly appreciated. Here's what I have so far: filesize_ = fs::file_size(filepath_); std::ifstream file(filepath_.file_string().c_str(), std::ios::in ); file.seekg (file_offset_, std::ios::beg); //offset typically 0 unless resuming transfer //just trying this for fun boost::asio::ip::tcp::socket::send_buffer_size option; data_socket_.get_option(option); //tcp socket uint64_t size = option.value(); while (bytes_sent < filesize_) { //i test a file 21200678 bytes long. This tranfers anywhere from 21135097 to 21196000. bytes_sent += data_socket_.send(boost::asio::buffer(file.rdbuf(), std::min(size,filesize_-bytes_sent))); //this always transfers 21204202 bytes_sent += data_socket_.send(boost::asio::buffer(file.rdbuf(), size)); } data_socket_.close(); boost::asio::async_read_until(control_socket_, response_, "\r\n", boost::bind(&FTPClient::handleRead, this, boost::asio::placeholders::error)); write_some vs. send give same results. I've also tried something like: char buf[1024]; socket.write_some(buf, file.readsome(buf, 1024)); which deosnt read all the bytes. Sometimes if I check file.rdbuf()->in_avail(), it reports 0 using above method and bytes_sent stops growing about 99% of the way through. I tired setting the the socket linger option to true. No go. I tried making the data_socket a buffered_write_stream, same results. What am I doing wrong? Sometimes bytes_sent is exactly the file size, but the remote file size is slightly less. Maybe closing the socket stream too early? That sends an eof which the server responds to but it should arrive AFTER the data i would think... no clue. please help :) In the meantime, I'm going to go rip up some FSF ftp client code from source forge heh. Thanks Chris

math/statistics policy-interface feedback requested.
by John Maddock 13 Jun '07

13 Jun '07

Following the successful review of the math-toolkit of special functions and statistical distributions the main feature request was for a better way of customising the library: both for choosing between precision vs speed tradeoffs, and for determining how errors are best handled. I've been experimenting with various policy-based interfaced based on Boost.Parameter, and I think I now have something useable, so I'd like to know what people think: Policy Defaults ~~~~~~~~~~~~~~~ The library will use a sensible set of defaults (throw on domain errors and internal evaluation errors, favour accuracy over speed etc), which can be changed via the usual macro mechanism, so adding: #define BOOST_MATH_DOMAIN_ERROR_POLICY errno_on_error #define BOOST_MATH_OVERFLOW_ERROR_POLICY ignor_error to a user-config header would do what they say to the default policies. Add Hock Changes: ~~~~~~~~~~~~~~~~~ We can create an ad-hock policy change at the call site by using the make_policy function, for example: using namespace boost::math::policy; using namespace boost::math; quantile( poisson(100), 0.05, make_policy( // 5 dicimal digits precision only digits10<10>(), // don't internally promote double->long double for extra precision: promote_double<false>(), // return integer result, immediately below the "real" value: discrete_quantile<integer_below>() )); Which returns the lower 95% quantile (ie critical value) of a poisson distribution with rate parameter of 100 event's per unit time. The result is calculated using only 10 decimal digits internal precision, truncated to the largest integer that gives a CDF less than 0.05. Predefined Policies ~~~~~~~~~~~~~~~~~~~ Although ad-hock policies are useful for testing, I imagine most sites would want a few carefully controlled (and tested) policies. To achieve that you define a typedef of the policy class: using namespace boost::math::policy; typedef policy< // Set error handling: domain_error<throw_on_error>, pole_error<throw_on_error>, overflow_error<throw_on_error>, evaluation_error<throw_on_error>, denorm_error<ignor_error>, underflow_error<ignor_error>, // calculate to 8 decimal digits internally digits10<8>, // don't promote double->long double for accuracy promote_double<false>, // Integer quantiles return the "outside edge": // below the real value for lower critical values, // above it for upper critical values, so that the // area inside contains *at least* the requested coverage: discrete_quantile<integer_outside_edge> > fast_quantile_policy; static fast_quantile_policy fast_quantile; Then we can just use: quantile( poisson(100), 0.05, fast_quantile); In our actual code. Currently this policy interface is vapourware: I have enough of a prototype implemented to know that it's possible to achieve this syntax (this is revision #3 already !), but there's a lot of hairy meta-programming to convert that into something that the library's internals can make use of... so I'd like to know what folks think before I invest too much time messing about with MPL :-) The main disadvantage I've noticed at present, is that the mangled names of the policy class - and therefore all the special functions etc - are *very* long. This has an impact on error messages: in particular we currently use BOOST_CURRENT_FUNCTION to get a nice formatted name of a function that's about to throw, but with function names a couple of pages long I don't think that will be possible with this interface any more :-( Thanks in advance, John Maddock.

multi_index and base class
by Andrej van der Zee 13 Jun '07

Hi, I'm trying to store these classes in a multi_index: struct Foo { int a; }; struct Bar :Foo { }; typedef multi_index_container< Bar, indexed_by< ordered_unique< member<Foo, int, &Bar::a> > > > Bar_container; Notice I have to use "Foo" in the "member<" line. However, even with this, when trying to do a search: Bar_container bar_container; int function() { Bar_container::nth_index<0>::type& a_index = bar_container.get<0>(); Bar_container::nth_index<0>::type::iterator i = a_index.find(5); if (i != a_index.end()) return -1; return 0; } I get this: /usr/include/boost/multi_index/member.hpp: In member function 'Type& boost::multi_index::detail::non_const_member_base<Class, Type, PtrToMember>::operator()(const ChainedPtr&) const [with ChainedPtr = Bar, Class = Foo, Type = int, Type Class::* PtrToMember = &Foo::a]': /usr/include/boost/multi_index/detail/ord_index_ops.hpp:65: instantiated from 'Node* boost::multi_index::detail::ordered_index_find(Node*, const KeyFromValue&, const CompatibleKey&, const CompatibleCompare&) [with Node = boost::multi_index::detail::ordered_index_node<boost::multi_index::detail::i ndex_node_base<Bar> >, KeyFromValue = boost::multi_index::member<Foo, int, &Foo::a>, CompatibleKey = int, CompatibleCompare = std::less<int>]' /usr/include/boost/multi_index/ordered_index.hpp:376: instantiated from 'boost::multi_index::detail::index_iterator<boost::multi_index::detail::orde red_index_node<typename SuperMeta::type::node_type> > boost::multi_index::detail::ordered_index<KeyFromValue, Compare, SuperMeta, TagList, Category>::find(const CompatibleKey&) const [with CompatibleKey = int, KeyFromValue = boost::multi_index::member<Foo, int, &Foo::a>, Compare = std::less<int>, SuperMeta = boost::multi_index::detail::nth_layer<1, Bar, boost::multi_index::indexed_by<boost::multi_index::ordered_unique<boost::mul ti_index::member<Foo, int, &Foo::a>, mpl_::na, mpl_::na>, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na, mpl_::na>, std::allocator<Bar> >, TagList = boost::mpl::vector0<mpl_::na>, Category = boost::multi_index::detail::ordered_unique_tag]' multitest2.cc:55: instantiated from here /usr/include/boost/multi_index/member.hpp:84: error: no match for 'operator*' in '*x' I've tried a few alternatives such as providing a custom compare function but I always get this error.

Surely there's a way to do this. Anyone know how ? Using gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21) and libboost 1.33.1.

Problems instantiating class Boost Python class
by Phil 13 Jun '07

13 Jun '07

Hi, I'm a newbie having some problems instantiating a class written in C++ in Python using Boost.Python. I can get a very simple example working when I expose a function outside of a class, that returns a string, but the below fails as shown, despite building. The enum in the same library however works fine. I've googled the error returned from Python and I get zero hits - has anyone get any idea what I'm doing wrong? I'm using Python 2.5, GCC 4.0.1 and Boost 1.33 on Mac OS X 10.4.9. I don't think it matters but I'm building the solution as a dynamic C++ bsd library in XCode and the changing the Mac OS X .dylib extention to .so as is required by Python. This all works for simpler examples and the enum in this example. Error: TypeError: __init__() should return None, not 'NoneType' Thanks, Phil. From header file example.h: enum payOffType { CALL, PUT }; class Option { public: //defaults to call Option( double strike, double expiry ); double getPutCallMultiplier(); private: double strike; double expiry; payOffType type; }; From cpp file example.cpp: Option::Option( double strike, double expiry ) : strike( strike ), expiry( expiry ), type( CALL ) { cout << "Option Contructor called"; } double Option::getPutCallMultiplier() { return ( type == CALL ) ? 1 : -1; } BOOST_PYTHON_MODULE(libphil_boost) { class_<Option>("Option", init<double, double>()) .def("getPutCallMultiplier", &Option::getPutCallMultiplier) ; enum_<payOffType>("payOffType") .value("CALL", CALL) .value("PUT", PUT) ; } Using Python on the resulting .so: $ python Python 2.5.1 (r251:54863, Jun 10 2007, 17:57:56) [GCC 4.0.1 (Apple Computer, Inc. build 5250)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import libphil_boost >>> p = libphil_boost.Option( 23, 23 ) Option Contructor calledTraceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: __init__() should return None, not 'NoneType' >>>

boost::pool issue
by v r 12 Jun '07

12 Jun '07

Hi, I have a main object that allocates many small objects via singleton_pool , and during its operation main obj uses up much memory so i want to release that memory before program termination, because main obj performs only support operations in my program. So upon main obj destruction i make a singleton_pool::purge_memory() call in main obj destructor, the memory is released and i should be quite happy,but when the main obj is constructed again the pool allocates twice as much memory as it used before, and it continues to double every time i construct/destruct the main object, so very soon my program hangs up. I wonder what have i done wrong? It seems like something is not reset on memory purge, or maybe it`s a bug? --------------------------------- Вы уже с Yahoo!?

[asio] Receiving non-UDP multicast frames?
by Eric Hill 12 Jun '07

12 Jun '07

I have been requested to write a tiny diagnostic application that will listen for Cisco Discovery Protocol (CDP) messages from Cisco switches on a workstation so that the workstation will "know" what switch port it is plugged into. I have found the following information with my limited google-foo: CDP Packet Format: http://www.cisco.com/univercd/cc/td/doc/product/lan/trsrb/frames.htm#xtocid… CDP Information: http://www.cisco.com/en/US/products/hw/switches/ps663/products_tech_note091… The latter link says that CDP uses a destination multicast address 01-00-0c-cc-cc-cc, HDLC protocol type 0x2000 on an Ethernet segment. This is where I get lost. Is that an Ethernet MAC broadcast, or a socket-based broadcast? Can I capture those CDP advertisements with asio? Eric

Binary 1.34 installer
by Luigi Ballabio 12 Jun '07

12 Jun '07

Hi all, I'm one of the developers of a project that requires a few Boost libraries. First of all, thanks to the people at Boost Consulting who made the binary installer available; we have a constant stream of new users asking for instructions on how to build Boost, and let's just say that since the installer was released for version 1.33.1, it streamlined our answers... we still had a few users we couldn't direct to this solution, though; namely, those behind a corporate firewall. Does the new installer for 1.34 work in this setting? I can't test it myself, as I'm not behind such a firewall. Thanks again, Luigi ---------------------------------------- Blessed is the man who, having nothing to say, abstains from giving wordy evidence of the fact. -- George Eliot

[Pool] pool_allocator with vector-of-vectors ??
by Williams, Alan B 12 Jun '07

12 Jun '07

I have a question about using the standard allocator interface in the boost.pool library. (I'm using boost 1.34.0 with g++ 3.4.3 on redhat linux, in case it matters.) I've successfully used boost::pool_allocator with individual std::vector objects, but I'm having trouble using it with a vector-of-vectors object, like this: std::vector<std::vector<int, boost::pool_allocator<int> > > myvec(1); myvec[0].push_back(99); The "push_back" line causes a seg-fault, which purify says is an array-bounds-write occurring in boost::simple_segregated_storage<unsigned long>::segregate. Am I misusing the pool_allocator? Thanks, Alan

[mpl] can't transform a map
by Yuval Ronen 12 Jun '07

12 Jun '07

I have the following code: #include <utility> #include <boost/mpl/map.hpp> #include <boost/mpl/transform.hpp> template <typename MplPair> struct make_ptr_pair1 { typedef std::pair<typename MplPair::first *, typename MplPair::second *> type; }; template <typename First, typename Second> struct make_ptr_pair2 { typedef std::pair<First *, Second *> type; }; int main(int argc, char *argv[]) { namespace mpl = boost::mpl; typedef mpl::map< mpl::pair<int, double> > my_map; //typedef mpl::transform< my_map, make_ptr_pair1<mpl::_1> >::type ptr_pair_seq1; //typedef mpl::transform< my_map, make_ptr_pair2<mpl::_1, mpl::_2> >::type ptr_pair_seq2; return 0; } If I uncomment any of the two mpl::transform lines in main(), the code doesn't compile (VC8). The point is to get a sequence of std::pairs out of the content of the mpl::map. Is there anything I'm doing wrong? Can mpl::transform be used for mpl::map? Maybe I can do it with fusion, but the above code seems to be something that's supposed to be working, isn't it? Yuval

MPL intersection of type sequences and compile-time performance
by Andrej van der Zee 12 Jun '07

12 Jun '07

Hi, Sorry if this already has been posted, but I have a problem with compile-time performance when trying to get the intersection of two type sequences. For example, when I do something like this: template<typename list1, typename list2> struct intersect { typedef typename boost::mpl::remove_if<list1, mpl::not_< mpl::contains<list2, mpl::_1> >::type type; }; typedef mpl::vector<a,b,...,z> l1; typedef mpl::vector<c,e,t,u,v> l2; typename intersect<list1,list2>::type my_intersection; Then for large type sequences compile-time becomes unacceptable (O(M*N)). Is there a better way to do this? Thanks, Andrej ___________________________________________________________ To help you stay safe and secure online, we've developed the all new Yahoo!

Performing static_cast<shared_ptr<base>*> on a shared_ptr<derived>*. Any guarantees?
by Pete Bartlett 11 Jun '07

11 Jun '07

I have taken over some code that boils down to ///begin code #include <iostream> #include <boost/shared_ptr.hpp> struct base { int i; base(int i_):i(i_) {} }; struct derived : base { derived(int i): base(i) {} }; int main() { boost::shared_ptr<derived> pd(new derived(5)); void* ptr_to_pd = &pd; boost::shared_ptr<base>* ptr_to_pb = static_cast< boost::shared_ptr<base>* >(ptr_to_pd); std::cout << "\n" << (**ptr_to_pb).i ; //Prints 5 } ///End code Now shared_ptr<B> and shared_ptr<A> are unrelated types, so IIUC there is no guarantee that this will work. Is that right? I know from the shared_ptr documentation that I should refactor in the direction of dynamic_ptr_cast (though complications not shown in the code above make that harder that). However for the time being this code appears to be working. Is that just a fluke? I.e. I am relying on the author of boost::shared_ptr and/or my compiler creators not to do something such that it doesn't work. Is there the possibility that any memory could be deleted twice? Or I am worrying over nothing and in fact there is a reason why the above is safe? Many thanks for any advice you can provide, Peter Bartlett

I want to remove items where the shared_ptr use_count is 1. map<string, shared_ptr<data> > Fred; RemoveIf(Fred.begin(), Fred.end(), boost::bind(std::equal_to<long>(), 1, boost::bind(&map<string, shared_ptr<data> >::value_type::second::use_count, _1) ) However, I get a compile error on ::second not being a class or namespace. Anyone know how I should do this? I'm a beginner at boost::bind, so be gentle....

Re: [Boost-users] [bind] Help with functional compositionofshared_ptr::use_count in std::map

> map<string, shared_ptr<data> > Fred; > > RemoveIf(Fred.begin(), > Fred.end(), > boost::bind(&map<string, shared_ptr<data> > >::value_type::second::unique, _1) > ) James, remove_if requires an assignment operator on the operated type but the value_type of a map is defined as std::pair< const T1, T2 >. The const on the first type will cause any assignment to fail. In other words, you can't use remove_if on a map. That said, in order to fix your bind you would need two functors. The type passed to the bind is the value_type of the map which is by definition a pair. You need to first invoke a functor on the pair to extract the second member and then call the member unique on the resulting smart pointer. In order to do so you'll need to write your own extractor, because the STL does not provide a functor to obtain the "second" field from a pair (I haven't found one in boost either). template< class Pair > struct second_of : std::unary_function< Pair, typename Pair:second_type > { typename Pair::second_type opertator()( const Pair& the_pair ) const { return the_pair.second; } }; std::for_each( Fred.begin(), Fred.end(), boost::bind( boost::shared_ptr< data >::unique, boost::bind( second_of< std::map< std::string, boost::shared_ptr< data > >::value_type >(), _1 ) ) ); Note that you can call for_each as it does not require the assignment operator.

Problems with boost.thread

I have some problems with boost.thread (version 1_34) under gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-52).

[program options] & also an apology to the list...
by jono 10 Jun '07

10 Jun '07

...for my earlier grumpy email about program_options. i'm was wanting to pass some sequences to some options using boost::program_options. something like: [me@here ~]$program --opt1 1 2 3 4 --opt2 5 6 7 8 --opt3 xxx yyy zzz if i use desc.add_options("opt1", value< vector<string> >()->multitoken(), "...") i get all the tokens to the end of the line. can i make multitoken() stop eating tokens by recognizing a syntactic element; either an option specifier or a token it can't interpret as a required type? can i inherit from the value_semantic class to read multiple tokens maybe? this whole library is very interesting but subtle. i do better when i can read examples of working code. does anyone know a more extensive discussion of it besides the distibution docs? ...which are great by the way! cheers jono

Problem with boost::program_options
by Jonas Bösch 10 Jun '07

10 Jun '07

Hi, I'm having a problem with boost::program_options. I attached a stripped-down version of the code that demonstrates the problem. I have a number of positional arguments ( "ops" ), and one normal argument ( "input-file,i" ). Now, if i run the program ./op_test pos0 pos1 pos2 -i non_positional it interpretes the "non_positional" as further positional arg, and not as parameter belonging to -i. Any hints on how to solve this are greatly appreciated. I ran it on: Mac OS X 10.4 on a G5, with the latest XCode ( gcc 4.0.1 ) boost 1.34 Jonas

BGL: INTERNAL COMPILER ERROR in VC7.1
by Yariv Tal 10 Jun '07

10 Jun '07

This one was already posted by Nicholas Burlett awhile back (see http://lists.boost.org/MailArchives/boost-users/msg06534.php) but I have some new info that may help. The problem: ========= When compiling code that uses the boost.graph library the VC7.1 compiler shouts: c:\boost_1_32_0\boost\mpl\aux_\preprocessed\plain\apply_wrap.hpp(48) : fatal error C1001: INTERNAL COMPILER ERROR As Nicholas already noted, this seems to be due to some compiler problem with the boost.graph out_edge_iterators since it is caused by the following lines in my code: (FilteredGraphGenerator::FilteredGraph is a typedef of a boost::filtered_graph) typedef boost::graph_traits<FilteredGraphGenerator::FilteredGraph> ::out_edge_iterator oedge_iterator; oedge_iterator edgesItr, edgesEnd; boost::tie(edgesItr, edgesEnd) = boost::out_edges(itr->first, m_g.m_filteredGraph); while (edgesItr != edgesEnd) { // do anything! } In fact, it seems to be related to the operator!= between iterators (if the while loop is commented out it compiles). How ever, the error persists even after changing the operator!= to operator== : while (edgesItr == edgesEnd) { // do anything! } ========================================================================== Some findings: =========== * We used to use boost_1_30_0 and the code used to compile PERFECTLY. The problem only appeared after migrating to boost_1_32_0. * Calling directly to the "equal" function in iterator_core_access instead of the operator== works. typedef boost::graph_traits<FilteredGraphGenerator::FilteredGraph> ::out_edge_iterator oedge_iterator; oedge_iterator edgesItr, edgesEnd; boost::tie(edgesItr, edgesEnd) = boost::out_edges(itr->first,m_g.m_filteredGraph); while (boost::iterator_core_access::equal(edgesItr, edgesEnd, boost::mpl::true_())) { // do somthing } * The error message location is at the mpl::apply_wrap2 function. Any relation to the mpl::apply2 function used for declaring the operator== in the BOOST_ITERATOR_FACADE_INTEROP_HEAD macro? Have these functions changed since v1.30.0?

Failing with "Getting Started on Windows" program
by Robert Murphy 10 Jun '07

10 Jun '07

Hello, Following instructions on the "Getting Started on Windows" page, I installed boost using the BoostPro 1.34.0 Installer on XP Pro. I included the Boost.Regex binaries as directed, too. I'm running VS C++ 2005 Express. SDK is not installed. All directories are linked to as instructed to do so in the properties window. I tried building the 2nd program: e-mail checker one. However I get "LINK : fatal error LNK1104: cannot open file 'user32.lib'" as an error. 'user32.lib' is in the SDK My questions are: 1. Must I have the SDK installed to use boost for general unit testing of code I personally generate? 2. Do I have to have the SDK installed for the above program to run? Thank you. _________________________________________________________________ Dont miss your chance to WIN $10,000 and other great prizes from Microsoft Office Live http://clk.atdmt.com/MRT/go/aub0540003042mrt/direct/01/

interprocess
by Jan Stetka 09 Jun '07

09 Jun '07

Hi, Interprocess still has not been included in the documentation on the main site yet, wouldn't it be good to include it there as soon as possible as it would increase the usage of interprocess. The "quick guide for the impatient" on maps is very good and a welcome addition to the documentation. The documentation at http://ice.prohosting.com/newfunk/ boost/libs/interprocess/doc/html/interprocess/quick_guide.html #interprocess.quick_guide.qg_interprocess_map reads "Boost.Interprocess's map is The construction of map is a bit tricky, because" which could be an editing or typing mistake as it doesn't currently make much sense.

Non-trivial examples of Boost::Interprocess library usage
by Evan Torrie 09 Jun '07

09 Jun '07

Hi I'm new to Boost, and also new to Boost::Interprocess. I've been reading through the documentation for Boost::Interprocess, and have successfully written an application which creates a tree like structure in a managed_memory_mapped_file; saves it to disk, and then other processes can reopen that mmap'ed file and traverse the tree. However, I feel like I really am not making the best use of the library, and would like to get more experience by reading other example code from significant applications Does anyone have source code of a non-trivial application that exercises shared memory or memory-mapped files, storing objects with pointers to other objects (and strings) into the shared memory, deleting, updating, retrieving them etc. Specifically, say I'm trying to port an existing heap-based structure into shared memory. struct foo { int x, y; std::vector< std::string > keys; struct foo* left, right; } struct foo* root; What would this translate to in the boost::interprocess world? Is it possible to write templatized versions of these data structures that would work either with the existing std::allocator heap-based memory or with boost::interprocess stateful allocators without needing to create two versions of this data structure? One problem I've encountered is that default constructors for boost::interprocess::vector/string etc are not possible since they need to be constructed with a stateful allocator... so, does this mean that any constructor for object foo requires an allocator to be passed in which is then used in the initializer list to initialize these member containers? Sorry if this doesn't make sense - but any help would be appreciated. Thanks Evan. ----------------------------------------- E> evan.torrie(a)yahoo.com

[integer] Request: long long (64 bits) support for int_t and uint_t
by Niels Dekker - mail address until 2007-11-30 08 Jun '07

08 Jun '07

I would like to have "long long" and "unsigned long long" supported by boost::int_t and boost::uint_t. E.g., on Win32, VC++, I would expect int_t<64>::least to get me a long long. Are there plans to add this kind of support? Otherwise, should I submit my request as a ticket to svn.boost.org/trac/boost ? It looks like "long long" support can be added quite easily, as I already did so on my local copy of boost/integer.hpp. -- Niels Dekker http://www.xs4all.nl/~nd/dekkerware Scientific programmer at LKEB, Leiden University Medical Center

boost::bind as composite
by Boris 08 Jun '07

08 Jun '07

Hi, I have two predicates f1 and f2 and I want to construct the predicate f4 = f1 && f2 using boost::bind. Unfortunately I observe a strange behaviour of boost::bind I can not explain. struct Test { int a; int b; }; Test t = { 1, 2 }; typedef boost::function< bool (Test const&) > Fn; Fn f1 = bind( &Test::a, _1 ) == 1; assert (f1( t )); // Ok Fn f2 = bind( &Test::b, _1 ) == 3; assert (!f2( t )); // ok Fn f3 = bind( std::logical_and< bool >(), bind( &Test::a, _1 ) == 1, bind( &Test::b, _1 ) == 3 ); assert (!f3( t )); // Ok Fn f4 = bind( std::logical_and< bool >(), f1, f2 ); assert (!f4( t )); // assertion failed Why does the predicate f4 behave different from f3? Thanks, Boris

[parameter] A few usage questions
by John Maddock 08 Jun '07

08 Jun '07

I have a few usage questions for the Boost.Parameter library: 1) If I want to have a function called "policy" that's declared using BOOST_PARAMETER_FUNCTION can I access the types of the arguments both from within the functions body and for the functions return type: BOOST_PARAMETER_FUNCTION( (return-type-computed-from-arguments), policy, tag, // 3. namespace of tag types (optional // optional parameters, with defaults (domain_error, *, throw_on_error) ) (deduced (optional (precision, *, boost::mpl::int_<53>()) ) ) ) { // what type are the arguments? } I realise I can do this with an argument pack, but then either my users will have to call the function with an extra set of parenthesis, or I will have to write a bunch of forwarding functions myself - which itself generates a "what the is the return type" problem. >From within the body of the BOOST_PARAMETER_FUNCTION generated function it appears that I can use the name "Args" to refer to the type of the argument pack, and maybe in the return type as well? But this isn't documented, so can I rely on it? 2) All the arguments I want to pass are actually going to end up being used in meta-programs: for symbolic values, I can make each one a unique enum type, and use the type of the argument (even though it's actually passed as a value) to generate my metacode. But I have one optional argument where I require the value to be an arbitrary compile time constant, the only interface I can come up with at present is something like: policy(_digits10 = mpl::int_<10>()); But I'd really like to be able to write: policy(_digits10 = 12); and have the "12" converted to mpl::int_<12> "by magic", but I can't think of any magic that could be applied here... anyone any ideas? Thanks, John.

[boost::variant] does 'incomplete<T>' still exist?
by jono 08 Jun '07

hi. i read a tutorial at http://electra.lbl.gov/stuff/variant/doc/tutorial.html which says a boost::variant type can be declared with an incomplete type in its typelist by using incomplete<T>. i'm using boost 1.33.1 & i can't find incomplete<T> anywhere. does it still exist? the tutorial is dated '14 February 2003'. can variants use incomplete types? i want to have a variant represent a type which has a variant member. can i do that? i'm working on a kind of envelope/letter idiom for dispatching operations on values. cheers jono

wave: preprocessing Visual C++ 2005 stl
by Ludovic Aubert 07 Jun '07

07 Jun '07

Hello boost wave users, I have written a sample program which uses boost wave and I am trying to run it on its own source code. The environnement (especially the stl) is Microsoft Visual C++ 2005. Since typically an include file like "vector" will be preprocessed many times (once for every compilation unit), I am saving all the preprocessed tokens in a map<string, map<tuple<int,int>,string> > token, so that token[path][make_tuple(line,col)] = value. Then for each path I am using a forward iterator to spit out all the values into a buffer. The major trouble I have is with the macros #define STD_BEGIN namespace std { #define STD_END } defined in the file "yvals.h" Somehow, STD_BEGIN and STD_END are replaced by blanks and I get "namespace std{}" at the end of the files instead. Looks like the line and col for these items are wrong ... I would like to know if someone has already successfully preprocessed the stl delivered with Visual C++ 2005. Thank you in advance for your reply Ludovic Aubert

Re: [Boost-users] port of GameDev SDL lib in Boost?
by Christian Henning 07 Jun '07

07 Jun '07

Fanzhe, I have been working on a sdl wrapper for boost::gil. It lets you draw on a canvas and react to event such as a timer event. I was thinking of outsourcing this portion so people can use just that. The good thing is the sdl is supporting almost the same platforms as boost does. The bad thing probably is the license sdl is using, LGPL. If you want I can give you a pointer for the code.

Uninitialized value p$m_value
by Paul 07 Jun '07

07 Jun '07

Hi, I'm trying to learn how to use the Boost Graph Library. Here is a very simple code example. #include <boost/graph/adjacency_list.hpp> #include <string> int main( void ) { using namespace std; using namespace boost; typedef adjacency_list< listS, vecS, directedS, // Vertex properties property< vertex_name_t, std::string >, // Edge properties property< edge_weight_t, int > > Graph; Graph graph; // Graph traits used to access graph's iterator types graph_traits< Graph >::vertex_descriptor a, b; a = add_vertex( graph ); b = add_vertex( graph ); graph_traits< Graph >::edge_descriptor ed; bool inserted; tie( ed, inserted ) = add_edge( a, b, graph ); // LINE 26 return 0; } When I compile this with g++ v4, I get on my Debian Etch system the warning for line 26: /usr/include/boost/graph/detail/adjacency_list.hpp:263: warning: 'p$m_value' is used uninitialized in this function Line 263 in adjacency_list.hpp looks as follows: inline stored_edge_property(Vertex target, const Property& p = Property()) : stored_edge<Vertex>(target), m_property(new Property(p)) { } What am I doing wrong and how can I fix that? Thank you. Regards, Paul

[filesystem] remove for directories
by Ovanes Markarian 07 Jun '07

07 Jun '07

Hello all! Is there any way to remove a directory using boost::filesystem? remove and remove_all throw an exception. Remove docs reference a POSIX remove(). There is written: [quote] If path does not name a directory, remove(path) shall be equivalent to unlink(path). If path names a directory, remove(path) shall be equivalent to rmdir(path). [/quote] Unfortunately remove does not behave so (on WinXP and Visual C++ 8). One more issue: the link to the POSIX remove() doc points to link() and not remove. With Kind Regards, Ovanes

Signal not disconnecting?
by Christian Mol 07 Jun '07

07 Jun '07

Hi, I'm using the signal library in my application. However if I call disconnect() on my connection object the connection is not removed. Is this default behaviour? I would like not having this behaviour because the signal is connected to a member function within an object that is actually deleted. Any ideas? Regards, Christian

BGL compile error
by gast128 07 Jun '07

07 Jun '07

Dear all, We want to (DLL) export a boost graph. Probably on (DLL) exporting, the compiler tries to generate code for every member function. However on VC++7.1 it gives then a problem with operator[]. This can be easily verified with the following case: void Foo() { boost::adjacency_list<> graph; graph[0]; } We use here Boost 1.33.0. Anyone an idea? Wkr, me

[preprocessor] usage problem
by Christopher Lux 07 Jun '07

07 Jun '07

hi, i want to do the following in a win32 project, which generates a dlls. commonly there is a macro defined like this: #ifdef DLL_BUILD #define __scm_export __declspec(dllexport) #else #define __scm_export __declspec(dllimport) #endif now i have several projects which generate dlls and depend on each other like: core_lib <- graphics_lib now to do this it is needed to differenciate between dll builds. lets say with a macro CORE_DLL_BUILD and GFX_DLL_BUILD. BUT i think this is hell ;) and thought of something like this: i would like to have one macro __scm_export(lib) which decides by the lib parameter which lib is build. i tried it the following way: (code broken out of context) #include <boost/preprocessor.hpp> #include <boost/preprocessor/detail/is_nullary.hpp> #if SCM_COMPILER == SCM_COMPILER_MSVC #define __scm_export(lib) export_(BOOST_PP_EXPAND(BOOST_PP_CAT(SCM_BUILD_LIBRARY_, lib))) #define export_(lib) BOOST_PP_IF(BOOST_PP_IS_NULLARY(lib), __declspec(dllexport), __declspec(dllimport)) #define __scm_private(lib) #else #pragma error "unsupported compiler" #endif this way i only have to define something like /DSCM_BUILD_LIBRARY_core=() for the core project and /DSCM_BUILD_LIBRARY_ogl=() for the graphics library and use __scm_export(ogl) and __scm_export(core) in the particular libraries. this works perfectly, BUT i am searching for a more elegant way to do this, because i do not like the definition of a unary macro for the projects. i would like more to define it this way: /DSCM_BUILD_LIBRARY=core and /DSCM_BUILD_LIBRARY=ogl for the libs. i experimented with BOOST_PP_IIF and so on, but the problem is if these macros are presented with an undefined macro (like when i use the one lib in the other) they do not use the false alternative and insert a lengthy macro. after a long night i came up with the BOOST_PP_IS_NULLARY workaround, but as is said i do not think is is a very good solution. dies anyone have suggestions how to solve this on a more elegant way?

Does date_time support POSIX timespec? I assume that timespec is standard POSIX. Is it not? If so, is it supported now, or how should it be supported. I'd be willing to help. terry

Operator overloading and enable_if
by Bill Buklis 07 Jun '07

07 Jun '07

For a template class I'd like to add * and -> operators for types that support it (mainly pointers). However, most instantiations of this class won't be pointers and therefore these operators won't be valid. I understand that enable_if can't directly support member functions. But, how can I do the equivalent of this? template< typename T > class Sample { T data; public: Sample( T& data ) : data(data) { } typename boost::enable_if< boost::is_pointer<T>, T >::type operator->() const { return(data); } typename boost::enable_if< boost::is_pointer<T>, typename boost::remove_pointer<T>::type >::type operator*() const { return(*data); } };

[mpl] Fusion/MPL examples
by Zeljko Vrba 06 Jun '07

06 Jun '07

The fusion library manual gives a single example and says "this is just the tip of the iceberg". I was wondering whether the slides/materials from the Boost Conference are available? I'm most interested in the lectures "Boost Metaprogramming Concepts and Frameworks" and "Fusion by example". I'm in the process of (slowly) reading THE "MPL book" (by Dave and Alexei), but I'm looking for more "down-to-earth" examples, rather than constructing small DSLs or creating optimized versions of swap. Synopses of the above lectures contain: "We'll also get a taste of high-level metaprogramming abstractions by using several Boost metaprogramming librariesMPL, Preprocessor, and the Fusion tuple library to solve real problems." "The emphasis for the examples will be on using Boost.Fusion in application code, rather than as infrastructure for library developers." I'm in the process of writing a recursive data structure with very similar operations at every level, but still with small behavioral variations. It seems like a perfect problem for metaprogramming, but I fail to map MPL's type manipulation routines to my down-to-earth problem. I was hoping to get some more insight in MPL from the materials for the abovementioned lectures. Get a new perspective and background to keep in mind while reading the MPL book. So, I kindly ask Dave Abrahams, Dan Marsden and Joel de Guzman to make their lecture materials available on-line, if possible. Thanks and best regards, Zeljko.

Re: [Boost-users] [serialization] Wrapper + make_nvp woes
by Dan Thill 06 Jun '07

06 Jun '07

Thank you for the fast reply, Robert. > Another idea is to cast your character array to a ... > character array - like static_cast< int [64] &>(my array address) > but that would require a constant size which might not work > for you. I'm not certain I quite understand this. Perhaps I didn't get my thoughts down coherently. I'm seeking to write my serialization like this (sorry I forgot to include this in my initial msg): char some_array[5] = "test"; .... ar & make_nvp("some_array", make_char_array(some_array, 5)); And obtain the following output: output.xml: ... <some_array>test</some_array> output.txt: .... 4 test .... --------------------------- My aforementioned make_char_array() works fine for text archives--just not when the result is composed with make_nvp(). > Finally you can use the blunt instrument approach. > > save(.... > std::string temp_string; > // copy data into temp_string > ar << temp_string > > load > .. do the opposite. Which is pretty much what my serialization wrapper is doing (this is in fact, what I wrote initially, before trying to make it a serialization wrapper). While I can certainly do the blunt approach, it will require me to split my serialization function :(

Linking problesm with boost/format.hpp
by ronnie_raj 06 Jun '07

06 Jun '07

Hello, I'm been developing an application on SUSE 9.3, gcc 3.3.5 and within my makefile I have the following for the CPPFLAGS "-g -O0" and the code complied and linked fine. I reached the end of the development and decided to up the optimisation so I changed the line to "-O2" and removed the "-g". When I got the linking stage I got the following error: /usr/lib/gcc-lib/i586-suse-linux/3.3.5/../../../../i586-suse-linux/bin/ld: `.gnu.linkonce.t._ZN5boost2io6detail22parse_printf_directiveIcSt11char_traitsIcESaIcEN9__gnu_cxx17__normal_iteratorIPKcSsEESt5ctypeIcEEEbRT2_RKSD_PNS1_11format_itemIT_T0_T1_EERKT3_jh' referenced in section `.rodata' of sg_gui_export_dialog.o: defined in discarded section `.gnu.linkonce.t._ZN5boost2io6detail22parse_printf_directiveIcSt11char_traitsIcESaIcEN9__gnu_cxx17__normal_iteratorIPKcSsEESt5ctypeIcEEEbRT2_RKSD_PNS1_11format_itemIT_T0_T1_EERKT3_jh' of sg_gui_export_dialog.o For what I can figure out its complaining about boost. I got the above error for 4 files and within all 4 files I use the "<boost/format.hpp>" library. I have used other boost libraries in other files but the linker didn't complain about them it was only the files where I used "format.hpp". I had a play around and if the CPPFLAGS line within the makefile and if it reads "-g -O2" then it links fine but if I don't have the "-g" it comes up with error above. Does anyone have any clue as to what I'm doing wrong?

[program_options] is this library actually useful
by jp＠day-one.com 06 Jun '07

06 Jun '07

hi, i hate rewriting getopts, but avaliable implimentations are always horrible, so there i was. then i decided to use boost::program_options .... all i want to do is something like..: translate --seq1 10 --seq2 10 13 --filter *.cpp *.hpp *.h where seq1 and seq2 can take any number of numbers between 0 and 255 anyway, if i use anything like desc.add_options ("seq1", po::value< std::vector<byte> >() -> multitoken() -> composing() -> notifier(seq1()), "byte sequence to find") it just returns all the tokens following the first option. is the library too stupid to stop eating tokens when it comes to another option? if so, what is its point? please... jono

boost:array lacks a statically-checked get()
by Benoit Hudson 06 Jun '07

06 Jun '07

Reading the archives, I see that the idea of adding a template <unsigned i> T get(); function to boost::array has been somewhat summarily rejected as unnecessary: http://lists.boost.org/boost-users/2005/08/12983.php et seq. And yet I'm finding myself wanting it repeatedly. Here are three places I've seen it crop up: (1) My current application is an arbitrary-dimensional geometry code. I want it to be a template argument what dimension we live in (2, 3, 4, ...). In d dimensions, a simplex has d+1 vertices on it, a point has d coordinates, and an face is a (d-1)-dimensional simplex that has d vertices. You can imagine the potential for off-by-one bugs (personally, I need not imagine). These get caught at runtime when using the array operator[], but I'd rather they be caught at compile time when possible. Therefore, when I'm feeling caffeinated, I write the appropriate BOOST_STATIC_ASSERT (which is of course itself sometimes off by one). (2) I've seen (and written) rather a lot of GUI, networking, and cross-language glue where a common idiom is to have an array of function pointers. Sometimes, the 'name' of the function is an integer read in at runtime. Sometimes, it is known at compile-time. Typically I've seen this implemented using an enum; calling function i is then functions[i](args), whereas calling function foo is functions[FOO](args). The former one can only be checked at run-time. The latter one should be checked at compile-time. It's fine for me to force me to write it as functions.get<FOO>(args) to get compile-time checking, but I do not want to be forced to change both entry FOO in the array, and every call to foo() elsewhere, if I change the name of the function (i.e. during debugging). When I've done this in the past, I've been living in C-land or C++ without boost, so the idea of compile-time checking didn't even occur to me (and, of course, bugs cropped up all the time). (3) Sometimes I don't need an array at all -- I just want a tuple with all values the same type. It's far handier to declare that type as array<foo, 4> than as tuple<foo, foo, foo, foo>. Also, we can now also use the uber-delicious BOOST_FOREACH on the array, which can't be done on the tuple. Summarizing: whenever a client wants to use both integers and names to access a field, array::get<> is useful and matches the boost philosophy of compile-time checking over runtime checking. The change is small in terms of LOC, and does not affect any code outside this one function (and, as far as I can determine, is even ABI-compatible with the prior array code). The runtime implication is nil. -- Benoît

[serialization] Wrapper + make_nvp woes
by Dan Thill 06 Jun '07

06 Jun '07

Greetings, I have a need to serialize plain old C character arrays as strings within the xml and text archive types. By default, these are serialized element by element. I've read the previous messages on the list on the perils of doing such (buffer overflows), and I hit across a somewhat acceptable solution using serialization wrappers. I'm new to all of this, so I based my implementation off of "nvp" and "binary_object" ------------------------------- struct char_array { char* const m_t; const std::size_t m_size; template<class Archive> void save(Archive & ar, const unsigned int /* file_version */) const { const std::string t(m_t); ar.operator<<(t); } template<class Archive> void load(Archive & ar, const unsigned int /* file_version */) const { std::string t; ar.operator>>(t); scASSERT_MSG(t.size() < m_size, "A corruption occurred"); strncpy(const_cast<char*>(m_t), t.c_str(), m_size); } BOOST_SERIALIZATION_SPLIT_MEMBER() explicit char_array( char* const t, std::size_t size) : m_t(t), m_size(size) {} char_array(const char_array & rhs) : m_t(rhs.m_t), m_size(rhs.m_size) {} }; ----------------------------------------------- The premise is simple, probably naive, and not too efficient: Convert each char[] to a std::string, and serialize that. Loading is just the reverse. However, I keep getting a compile time exception in the xml archive loading code. This is with Boost 1.33, VC8. 1>c:\Boost\include\boost-1_33_1\boost/archive/basic_xml_oarchive.hpp(86) : error C2027: use of undefined type 'boost::STATIC_ASSERTION_FAILURE<x>' 1> with 1> [ 1> x=false 1> ] 1> c:\Boost\include\boost-1_33_1\boost/archive/detail/interface_oarchive.hpp(78) : see reference to function template instantiation 'void boost::archive::basic_xml_oarchive<Archive>::save_override<T>(T &,int)' being compiled 1> with 1> [ 1> Archive=boost::archive::xml_oarchive, 1> T=const std::string 1> ] 1> d:\SDEV8\SOURCE\include\sc_s11n/char_array.h(49) : see reference to function template instantiation 'Archive &boost::archive::detail::interface_oarchive<Archive>::operator <<<const std::string>(T &)' being compiled 1> with 1> [ 1> Archive=boost::archive::xml_oarchive, 1> T=const std::string 1> ] It seems as if, after serializing the nvp object, it's expecting an nvp object around the std::string. Is there a way that I can call the default serialization for std::string from my char_array wrapper, without having it go through the normal xml specializations which require it to be part of an nvp? I'm new with this, so please be gentle. I've consumed almost the entire list archive and I can't come up with a fix. Thanks, Dan

[serialization]: text (xml) iarchive - format options for integers?
by Frank Bergemann 06 Jun '07

06 Jun '07

Hi, can i make xml_iarchive accept "0x11" instead of "17" for an int type data element? Or do i have to derive my own iarchive and implement that myself? \Frank _______________________________________________________________ SMS schreiben mit WEB.DE FreeMail - einfach, schnell und kostenguenstig.

by Dominik Heide 06 Jun '07

06 Jun '07

Hi there, I want to delete a vertex from a graph and later reinsert it again. I did this by removing all edges from that vertex and later adding the edges again. But the behavior of the program quite strange. First, I use a undirected adjacancy list typedef adjacency_list<vecS, vecS, undirectedS, no_property, no_property> Graph; When, use Graph g, gs; // set g typename graph_traits<GraphT>::vertex_iterator vi, ve, vii, vei; typename graph_traits<GraphT>::out_edge_iterator out_i, out_end, tmp; for( tie(vi, ve) = vertices(g); vi != ve; vi++) { gs = g; clear_vertex( *vi, g) // some code g = gs; } everything is fine. I don't want to save the whole graph since I only delete a couple of edges. Therefore, I did vector<typename graph_traits<GraphT>::vertex_descriptor> deletedEdges; typename vector<typename graph_traits<GraphT>::vertex_descriptor>::iterator dei; typename graph_traits<GraphT>::vertex_iterator vi, ve, vii, vei; typename graph_traits<GraphT>::out_edge_iterator out_i, out_end, tmp; ... for( tie(vi, ve) = vertices(g); vi != ve; vi++) { for( tie( out_i, out_end ) = out_edges( *vi, g); out_i != out_end; out_i++) { deletedEdges.push_back(target(*out_i, g)); } clear_vertex( *vi, g) // some code for(dei = deletedEdges.begin(); dei < deletedEdges.end(); ++dei) { add_edge( *vi, *dei, g); } } This code does not restore the graph completely. Although it looks the same the shortest paths are different to the ones with the above code. Is there something about clear_vertex() I don't know and therefore don't restore corectly? Any help appreachiated, Thank you, Dominik

[BGL] topological_sort compile error
by David A. Greene 05 Jun '07

05 Jun '07

Hi everyone, I'm having trouble with BGL's (Boost 1.33.1) topological sort. In my source code I have this simple call: std::vector<my_vertex> rev_topo_order; topological_sort(*t, std::back_inserter(rev_topo_order)); Here "t" is an iterator to a list of graphs declared like this: typedef boost::adjacency_list< boost::setS, // Out edge list type boost::listS, // Vertex list type boost::bidirectionalS, // Needed for DAG, topo sort my_property_bundle // Vertex properties > my_graph_type; The error trace below is mostly gobbledygook to me, but it looks like it's running into trouble with BGL's default bgl_named_params. The call chain runs through this curious bit of code: template <typename VertexListGraph, typename OutputIterator> void topological_sort(VertexListGraph& g, OutputIterator result) { topological_sort(g, result, bgl_named_params<int, buffer_param_t>(0)); // bogus } That looks...interesting to me. What's with the "bogus" comment? Any idea what's going on here? Any more information I can provide that would be helpful? The gmane archives show that Renaud Lepere ran into this problem in August '06 but I can't find any replies to his question. He gave a small example which I've confirmed reproduces the problem with g++ 4.1.2: #include <boost/graph/graph_traits.hpp> #include <boost/graph/adjacency_list.hpp> #include <boost/graph/depth_first_search.hpp> #include <boost/graph/visitors.hpp> #include <boost/graph/topological_sort.hpp> #include <iterator> typedef boost::adjacency_list<boost::vecS, boost::listS, boost::bidirectionalS, int, int > Graph; typedef boost::graph_traits<Graph>::vertex_descriptor Vertex; typedef std::vector< Vertex > Vertices; int main() { Graph g; Vertices vs; boost::topological_sort(g, back_inserter(vs)); } Thanks for any help you can give. -Dave ---------------------- Error trace ---------------------- ./boost-1_33_1/boost/property_map.hpp: In member

Newbie question: IPC
by Stew Paddaso 05 Jun '07

05 Jun '07

Does boost currently provide facilities for named pipes and/or shared memory between processes? I didn't see any reference to it after looking at this webpage: http://www.boost.org/libs/libraries.htm After doing a Google search, I noticed that the shmem library appears to have been accepted after review, but it is not listed on the page I referenced above. Thanks.

[boost.intrusive] Assertion failure with SunCC
by Zeljko Vrba 05 Jun '07

05 Jun '07

The following simple program crashes with assertion failure when compiled under Solaris 11 with SunCC: Sun C++ 5.8 Patch 121018-10 2007/02/21 Assertion failed: node_algorithms::unique(to_insert), file boost/boost/intrusive/list.hpp, line 168 I'm using the latest Boost.Intrusive from CVS (snapshot taken 2007-06-03). I have tracked the problem, but I don't know wheter it's the code or compiler problem; see below the code for cause. == Begin code // Program to demonstrate a bug with SunCC and member hooks. #include <boost/intrusive/list.hpp> struct klass { void *data_klass; boost::intrusive::list_member_hook<> hook_; typedef boost::intrusive::list< boost::intrusive::list_member_hook<>::value_traits< klass, &klass::hook_>, false> list; }; static klass Gd; static klass::list Gl; int main(void) { => Gl.push_back(Gd); return 0; } == End code When the program is started, the hook's prev_ and next_ members are initialized correctly to &Gd.hook_ (0x8062dd8). The member_value_traits instance is by dbx resolved to boost::intrusive::detail::member_value_traits< klass,boost::intrusive::list_member_hook< (boost::intrusive::linking_policy)1,void*>, klass::hook_>::to_node_ptr ^^^^^^^^^^^^ Corresponds to the template P parameter. The statement MemberHookType* result = &(value.*P); sets result to 0x8062dd4 (4 bytes off from the hooks address). Finally, in push_back method, the to_insert value receives 0x8062dd4 which equals &Gd (ie. it points to the start of the object) instead of &Gd.hook_. Should this be reported as a compiler bug? BTW, I'll try using base hooks as a workaround. (PS: the code works fine with gcc4.2)

lib folder?
by Mike Wyatt 05 Jun '07

05 Jun '07

I just installed MinGW and Boost. The boost_1_34_0 folder I extracted from the downloaded zip did not contain a "lib" folder, which is referred to in the Getting Started for Windows guide (http://www.boost.org/more/getting_started/windows.html) I've already built all the Boost libraries, so I'm guessing that I need to copy the lib folder from the new stage folder into the boost root. Is that correct? Also, I built bjam with the "mingw" toolset, and Boost with "gcc". Is that a problem? Here are the commands I ran: *Building bjam*: c:\Program Files\boost_1_34_0\tools\jam\src\build mingw *Building Boost*: c:\Program Files\boost_1_34_0\bjam --build-dir=build --toolset=gcc stage Does that make sense? Am I doing everything right, so far?

Boost 1.34 and VC++ x64

This was pretty straightforward for 1.33, but 1.34 using BB2 seems to have changed things a bit. There doesn't seem to be any documentation on compiling 1.34 for x64 with VC++ - can anyone offer some insight?

Hi, I am new to BOOST and to ACE. Pardon me if this question appears stupid for the seasones BOOST/ACE developers/users. From what little I know of the two frameworks, I am noticing many overlapping functionalities (shared memory, streams, threads). Is there some place/someone that can provide me a top level differences and situations that makes one framework more suited than the other. Any help or pointers is greatly appreciated. Thanks in advance. with best regards, dhruva -- Dhruva Krishnamurthy Contents reflect my personal views only!

Formatting and passing variable parameters.
by Prasanta K Chakravarty 05 Jun '07

05 Jun '07

Hi, 1) I have to generate unique id on the basis of file name and line no. For that I am using macros __FILE__ and __LINE__. But __FILE__ is giving full path with the file name and two double quotes at the begining and end(for example, "C:\Project\Test\log.cfg" ). I need to get the unique id in the format as <file name>_<line no>. For example if above is the file description and let line no is 11, then the unique id would be log_11. Please suggest. 2) I have to pass variable no of arguments in the macro. So, I want to use Boost PARAM macro. For example, if LIST is the macro name and I want to call it as LIST(MSG_ID, "good", 5, "failed", "50%", 10); Here parameters are of different types, only the fist parameter is fixed that is string type and always with same variable name. Other parameters will vary. Please help me out in making the macro with variable no. of parameters. Please suggest, Thanks Prasanta

[boost] [bimap] New Version
by Matias Capeletto 05 Jun '07

05 Jun '07

Hello boost, I have released a new version of the Boost.Bimap. The main attraction of this new release is the possibility to add information about each relation. I have been working very hard to ensure that Bimap works well with the others boost libraries. I have added new sections to the "Bimap and Boost" docs to show how to combine them. For example, from Bimap and Boost.Foreach: ------------------------------------------------------------------------------------------------------ typedef bimap< int, string > bm_type; bm_type bm; assign::insert( bm ) (1,"one") (2,"two") (3,"three"); BOOST_FOREACH( bm_type::right_const_reference p, bm.right ) { std::cout << p.first << " ---> " << p.second << std::endl; } ------------------------------------------------------------------------------------------------------ prints: ------------------------------------------------------------------------------------------------------ one ---> 1 three ---> 3 two ---> 2 ------------------------------------------------------------------------------------------------------ ================================================== I really need feedback! ================================================== If you are using this library please send me your comments (if you want by private email: matias <dot> capeletto <at> gmail <dot> com ) Library sources are in the vault: ---------------------------------------------------------------------------------------------------- http://tinyurl.com/2t8c87 Documentation can be viewed online here: ---------------------------------------------------------------------------------------------------- http://tinyurl.com/22sja5 Or can be downloaded from: ---------------------------------------------------------------------------------------------------- http://tinyurl.com/22jfdf Main changes ---------------------------------------------------------------------------------------------------- Lib: * Added support for information about the relations * Added range_type and const_range_type typedef to indexed views * Change the way you tag the collections. * hard implementation decision * Some small bug fixes Docs: * New relation and pair layout diagram * New section: Additional information * More examples in Bimap and Boost * New section: Bimap and Boost.Xpressive * New section: Bimap and Boost.Typeof * New section: Bimap and Boost.Foreach * Update the reference Comments are welcome Best regards Matias

[program_options] allow_unregistered() function for parse_environment
by Chris Weed 04 Jun '07

04 Jun '07

Hi, I would like to parse the environment variables on my system, but also allow unregistered options, similar to <http://www.boost.org/doc/html/program_options/howto.html#id1593176> with the command line parser. Is this possible? I can't seem to get it to work. Thanks, Chris

[multi_index] MSVC 8.0 visualizers for boost::multi_index_container
by Filip Konvička 04 Jun '07

04 Jun '07

Hello all, here is another version of MSVC 2005 visualizers for multi_index_container. Thanks to Joaquín for his invaluable support! This version supports sequenced, random_access, ordered and hashed indices. Hashed indices are visualized including the internal bucket structure, indicating empty bucket, single-item bucket and multiple-item bucket (see the example below). As in the previous version, contents of autoexp.dat.txt go into Microsoft Visual Studio 8\Common7\Packages\Debugger\autoexp.dat For your container to be visualized, you need to call the VISUALIZE_MULTI_INDEX_CONTAINER macro at the global namespace level (see the attached example, test2.cpp, and a screenshot of a test2.cpp debugging session, sample_hash.png). I strongly recommend using #define BOOST_MULTI_INDEX_LIMIT_INDEXED_BY_SIZE 5 #define BOOST_MULTI_INDEX_LIMIT_TAG_SIZE 3 #define BOOST_MULTI_INDEX_LIMIT_COMPOSITE_KEY_SIZE 5 in order to reduce symbol name lengths, because otherwise the resulting symbols are too long for the visualizer to work (this typically happens with more than 1 index in a multi_index_container). Also beware, using type hiding techniques described at http://boost.org/libs/multi_index/doc/compiler_specifics.html#type_hiding will cause visualizers to fail. Enjoy!

CGAL and the BGL
by Andreas Fabri 04 Jun '07

04 Jun '07

The CGAL Open Source Project is pleased to announce the release 3.3 of CGAL, the Computational Geometry Algorithms Library, a robust, easy-to-use, and efficient C++ software library of geometric data structures and algorithms. We don't post the full announcement here, because that would be off-topic, but we want to point out that CGAL comes with partial specializations of the boost::graph_traits for several CGAL data structures and overloaded versions of the global functions for graph traversal. This is done for the 2D triangulations, the 2D arrangements of curves, and the polyhdral surface, that is for data structures with vertices and edges. This allows for example to compute the Euclidean minimum spanning tree of a point set in the plane, by running the BGL minimum spanniung tree algorithms on a CGAL 2D Delaunay triangulation, without converting the latter to a BGL graph. For more iformation see http://www.cgal.org/Manual/3.3/doc_html/cgal_manual/packages.html#Pkg:BGL

[multi_index] MSVS 2005 visualizers?
by Filip Konvička 04 Jun '07

04 Jun '07

Hi, I just wanted to know if anyone succeeded creating a visualizer for multi_index containers. I'd love to spend some time doing that for the good of the community (and my own, of course :-)), but I could not find any data members for exploration in the debugger's watch window. Any suggestions? See the following blog for more info: http://www.virtualdub.org/blog/pivot/entry.php?id=120 Some info can be found in the autoexp.dat file directly - there are pre-defined visualizers for eg. std::map (which works nice). Thanks, Filip

[date_time] UNICODE and wcout problems
by Filip Konvička 04 Jun '07

04 Jun '07

Hi, in MSVC 8.0 _UNICODE build, after I send a ptime to wcout, I can no longer print "international" characters. When I use a temporary wostringstream for printing the ptime, everything is OK. Minimal repro see below (the "2" at the end is never printed). With some characters like the "š" in the example, the output is totally cut off; with others, like "á", the codepage is changed, so the characters are displayed incorrectly. Any suggestions? Thanks, Filip // _UNICODE must be defined; the "2" is never printed. #include <string> #include <iostream> #include <sstream> #include <locale.h> #include <boost/date_time/posix_time/posix_time.hpp> using boost::posix_time::ptime; using boost::date_time::not_a_date_time; int main() { wstring intl=L"\x161"; wostringstream ss; ss << ptime(not_a_date_time); wcout << ss.str() << endl; wcout << intl << endl; wcout << L"1" << endl; wcout << ptime(not_a_date_time) << endl; wcout << intl << endl; wcout << L"2" << endl; }

[thread_safe_signals] won't compile on VC71
by David Matz 04 Jun '07

04 Jun '07

Hello, I'm very impressed from Mr. Hess' work on thread safe signals for the boost library. In my opinion it's a great step to provide thread safe signals in a common library like boost and I like to use it as replacement for third party libs. Unfortunately I going in trouble when using the latest version of this module (thread_safe_signals-2007-03-19.tgz which is the same as out of the cvs). I can't get it compile on Microsoft VS71.

[interprocess]
by Aaron W. LaFramboise 03 Jun '07

03 Jun '07

I just got Boost.Interprocess working, and it's really an amazing library. Ion, it's obvious you've put a lot of time into this library, and the result is really nice. However, I've had these issues so far: (1) Is there a way to get a managed_shared_memory segment to tell me allocation statistics? What I'd like is something that can tell me. (a) Segment size (b) Allocated memory (c) Most importantly, free memory (2) It's been brought up before, but there seriously needs to be a way to grow managed shared memory segments. I understand that this is really tricky to implement, and probably just as tricky to use safely, but it's an important feature, in my opinion. I guess the main difficulties here are the potential change of base, and atomicity? (3) Regarding priv_open_or_create() in managed_open_or_create_impl.hpp, this implementation creates some small annoyances for me by throwing. I don't have any idea how to tell if POSIX O_CREAT actually created anything or not. However, I'm using Windows, and on Windows, you always can tell, as far as I know, both for file creation and named shared memory object creation. Would it be difficult to avoid throwing for the Windows case?

[date_time] nanosec resolution compile problem
by Christopher Lux 02 Jun '07

02 Jun '07

Hi, i am trying to use date_time with nanosec resolution for the fractional seconds part. So i define BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG in my projects using date_time. Now i get the compiler warning below. I found out that the problem in the said function is that in boost/date_time/date_duration.hpp the struct duration_traits_adapted defines the int_type as long and not as int_64t. The warning is generated in the add_time_duration() funtion of the split_timedate_system class. So i imagine that this is a bigger issue, because if the durations get bigger than what a long can hold (what will happen fast with nanosec resolution) the problems will come. Can this be resolved with an small fix to the duration_traits_adapted struct or have there to be more fixes? Here the compiler warning (VS.net 2005 SP1) boost\boost/date_time/time_system_split.hpp(189) : warning C4244: 'initializing' : conversion from '__int64' to 'long', possible loss of data D:\_devel\schism_wc_x86\schism\projects\cmake\..\..\ext\inc\boost\boost/date_time/time_system_split.hpp(180) : while compiling class template member function 'boost::posix_time::simple_time_rep boost::date_time::split_timedate_system<config>::add_time_duration(const boost::posix_time::simple_time_rep &,boost::posix_time::time_duration)' with [ config=boost::posix_time::posix_time_system_config ] D:\_devel\schism_wc_x86\schism\projects\cmake\..\..\ext\inc\boost\boost/date_time/time.hpp(52) : see reference to class template instantiation 'boost::date_time::split_timedate_system<config>' being compiled with [ config=boost::posix_time::posix_time_system_config ] D:\_devel\schism_wc_x86\schism\projects\cmake\..\..\ext\inc\boost\boost/date_time/posix_time/ptime.hpp(32) : see reference to class template instantiation 'boost::date_time::base_time<T,time_system>' being compiled with [ T=boost::posix_time::ptime, time_system=boost::posix_time::posix_time_system ] -chris -- Christopher Lux | | Bauhaus University Weimar | Faculty of Media - Virtual Reality Systems Group

converting ptime to/from CLR (.NET) DateTime
by Jens Schluetter 02 Jun '07

02 Jun '07

Hi, I'm kinda stuck. I'm working on an inter op library to glue C++ code that uses ptime with C# code that uses (of course) the .NET DateTime format. Since the system needs the outmost performance I'm looking for a way to use binary conversion. Conversion from .NET to ptime is easy since there is a from_ftime<> conversion method, however the other direction is somewhat blocked since no ptime to FILE_TIME conversion exists. My current workaround is using ISO time strings but performance is somewhat dismal since there is a lot of string <> binary conversion. Does anyone know of a more straight forward (binary)way of converting? And just in case, using regular time_t as common denominator is not an option since at leas millisecond resolution is required. I'd be greatful for any recommendations/ideas. Cheers, Jens.

[BGL] boost::bind fails to compile when used with edge iterators in for_each

[iostreams] skip bug (repost)
by Phillip Seaver 01 Jun '07

01 Jun '07

I ran into a problem when using restrict on a file_source. The problem was that it decided that the stream wasn't seekable and called the version of skip that reads a character at a time until it gets to the requested offset, instead of just calling seek. The code was similar to this: namespace io = boost::iostreams; std::string filename; io::filtering_istream rstr(io::restrict(io::file_source(filename), 10, 100)); I've attached a patch that solved my problem. It was checking to see if the device was seekable (which means input_seekable and output_seekable), but since it was an input device, it was just input_seekable.

Problem with 1.34 Regex Package
by Jeffery Cavallaro 01 Jun '07

01 Jun '07

Hi, all! I am a bit of a newbie, so forgive if this has already been covered. The 1.34 regex package (or at least my build of it on FC6) appears to be broken. Please consider the following: #include <iostream> #include <iomanip> #include <boost/regex.hpp> int main(int argc, char *argv[]) { boost::regex rl("ab"); boost::regex ru("AB"); bool pass = regex_search("ab", rl); std::cout << std::boolalpha << pass << std::endl; pass = regex_search("AB", ru); std::cout << std::boolalpha << pass << std::endl; return EXIT_SUCCESS; } When built with 1.33 (as delivered with FC6), both tests return true. When built under 1.34 (downloaded and built), the uppercase test returns false. Yuck. Am I missing something?

[Boost.Test 1.34] Multiple instances of unit_test_log_t singleton
by Kolya 01 Jun '07

01 Jun '07

Hi, All! I am using Boost.Test library in my own application and I have included boost/test/unit_test.hpp in many my cpp-files. When I used boost version 1.33.1 all works fine. But in version 1.34 I have following compiler error: file1.obj : error LNK2005: "class unit_test_log_t::boost::unit_test_log_t & boost::unit_test::`anonymous namespace'::unit_test_log" (?unit_test_log@?A0xa35d3712@unit_test@boost@@3AAVunit_test_log_t@23@A) already defined in file2.obj After including boost/test/unit_test.hpp class unit_test_log has multiple instances. See boost/test/unit_test_log.hpp for details: BOOST_TEST_SINGLETON_INST( unit_test_log ) It means that following code will be included in many cpp-files! namespace { unit_test_log_t & inst = unit_test_log_t::instance(); } When I replace BOOST_TEST_SINGLETON_INST( unit_test_log ) in boost/test/unit_test_log.hpp with namespace {extern unit_test_log_t & unit_test_log;} and in one of my cpp-files add: namespace boost { namespace unit_test { BOOST_TEST_SINGLETON_INST( unit_test_log ) } } all works fine May be I do not understand something? Is there any legal workaround from this situation? I do not like touch boost core files by myself. Thank you! VC++ 7.1, boost 1.34, xp sp2.

Bind: more convenience operators?

Bind has operator! overloaded to allow convenient notting of bound functions. Is there a specific reason not to overload all other operators in a similar way, for example for defining an AND of two predicates f and g as boost::bind( f, _1 ) && boost::bind( g, _1 )? Arno

[TR1] Configuration macros
by Scott Meyers 01 Jun '07

01 Jun '07

I'm having trouble understanding the information at http://www.boost.org/doc/html/boost_tr1/config.html, and having already spent a fair amount of time running test programs and pouring over the output of the preprocessor for various compilers, I'm hoping that somebody in the know can just explain things to me. My goal is simple: use Boost.TR1 such that if my compiler ships with a library with support for whatever TR1 component I want to use, I'll get that native support. But if the library that ships with the compiler lacks support for the TR1 component I need, I want to fall back on the Boost implementation, if there is one. And I want to uniformly refer to TR1 components as if they are in the namespace std::tr1. My reading of the above-referenced page leads me to believe that this is the behavior I'm supposed to get by default. And it's consistent with the tests I've performed using VC8 and g++ 4.1. But then I read this: > The configuration macros used by each TR1 component are documented in each library section (and all together in the Boost.Config documentation), but defining BOOST_HAS_TR1 will turn on native TR1 support for everything (if your standard library has it), which can act as a convenient shortcut. This kind of suggests that I should define BOOST_HAS_TR1. Should I? So far I have not. And then I read this: > Boost.TR1 does not currently enable gcc's native TR1 implementation as this is currently in an early stage of development. However, you may choose to do so by defining BOOST_HAS_GCC_TR1. This pretty clearly suggests that I should define BOOST_HAS_GCC_TR1. Should I? So far, I have. I've also found that unless I define it like this, > #ifdef __GNUC__ > #define BOOST_HAS_GCC_TR1 > #endif compilation with VC8 fails, which I find kind of strange. Here's an error I get: > D:\C++\Boost\Current\boost/tr1/type_traits.hpp(11): fatal error C1083: Cannot open include file: 'type_traits': No such file or dire > ctory Why should defining BOOST_HAS_GCC_TR1 have any effect on a VC8 compilation? All clarification about the correct settings of TR1 configuration macros for at least VC8 and g++ 4.1 would be much appreciated. Thanks, Scott

[tokenizer] position of tokenizer
by Seweryn Habdank-Wojewódzki 01 Jun '07

01 Jun '07

Hi Is that possible to take actual position of the tokenizer in the parsed string? The question is motivated by such a case: 1. there is a line with data separated by e.g. "\t' sign 1 23 3.45 21 2093 494 3.4 2. important is only some of them let say from 2nd token to 5th token, but after parsing them I want to pass tokens from 6th to the end to the other string. Now I am iterating tokenizer to the end, and concatenate it. If I have had a position of tokenizer on the string I can simply create new substring with out iteration. Maybe there is other solution for that. Regards. -- |\/\/| Seweryn Habdank-Wojewódzki \/\/

Bind & Memory Leakage

BoundsChecker is reporting a memory leak for every 'bind' call. I am using the threadpool includes, v 0.2.3, with "libboost_thread-vc71-mt-gd-1_33_1.lib", MSVC 7.1. Any help is appreciated. The usage is similar to the following working example: void task(int param1) { // performs some task printf("%d : Param1 : %d\n", GetCurrentThreadId(), param1); Sleep(1000); } void foo() { boost::threadpool::pool tp(5); // Threadpool with 5 threads while (1) { for (int i = 0; i < 10; i++) { // Seems like there is memory allocation which is not // deallocated after returning from the function call. tp.schedule(boost::bind(task, i)); } tp.wait(); // wait to finish off the remaining tasks Sleep(5000); // sleep for 5 seconds } }
