[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?

[date_time] Posix timespec support?
by Terry G 07 Jun '07

07 Jun '07

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?

[function] Bug in 1.34.0 with Sun Studio on Solaris
by Markus Bernhardt 06 Jun '07

06 Jun '07

Hi, I get the following warnings when using a boost::thread_specific_ptr<unsigned int> and compiling with Sun Studio 11 (with latest patches) or Sun Studio 12 on Solaris x86. Warning: Could not find source for boost::type_traits::ice_not<0>::value. "../../../build/debug/include/boost/function/function_template.hpp", line 407: Warning: Could not find source for boost::detail::function::function_allows_small_object_optimization<boost::detail::tss_adapter<unsigned>>::value. A similar warning is reported when I use boost::bind. Every comment is apreciated. Markus

[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

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.

[Graph] remove edges and reinsert them
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;

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
by Cory Nelson 05 Jun '07

05 Jun '07

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?

05 Jun '07

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

[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. I tried with gcc and VS8 and it works but for the VS71 compiler which we are working it fails. As mentioned in the documentation I included the headers of thread_safe_signals before the normal boost headers which are in fact 1_33_1 (same results with 1_34_0). The I picked up a sample project signal_test.cpp from boost/test/ and start to compile it but it fails with the following compiler hints: Kompilieren... signal_test.cpp ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(95) : error C2143: Syntaxfehler: Es fehlt ',' vor '&' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(109): Siehe Verweis auf Instanziierung der kompilierten Klassenvorlage 'boost::slot0<R,SlotFunction>' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(95) : error C2143: Syntaxfehler: Es fehlt ',' vor '&' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(109): Siehe Verweis auf Instanziierung der kompilierten Klassenvorlage 'boost::slot1<R,T1,SlotFunction>' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(95) : error C2143: Syntaxfehler: Es fehlt ',' vor '&' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(109): Siehe Verweis auf Instanziierung der kompilierten Klassenvorlage 'boost::slot2<R,T1,T2,SlotFunction>' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(95) : error C2143: Syntaxfehler: Es fehlt ',' vor '&' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(109): Siehe Verweis auf Instanziierung der kompilierten Klassenvorlage 'boost::slot3<R,T1,T2,T3,SlotFunction>' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(95) : error C2143: Syntaxfehler: Es fehlt ',' vor '&' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(109): Siehe Verweis auf Instanziierung der kompilierten Klassenvorlage 'boost::slot4<R,T1,T2,T3,T4,SlotFunction>' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(95) : error C2143: Syntaxfehler: Es fehlt ',' vor '&' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(109): Siehe Verweis auf Instanziierung der kompilierten Klassenvorlage 'boost::slot5<R,T1,T2,T3,T4,T5,SlotFunction>' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(95) : error C2143: Syntaxfehler: Es fehlt ',' vor '&' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(109): Siehe Verweis auf Instanziierung der kompilierten Klassenvorlage 'boost::slot6<R,T1,T2,T3,T4,T5,T6,SlotFunction>' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(95) : error C2143: Syntaxfehler: Es fehlt ',' vor '&' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(109): Siehe Verweis auf Instanziierung der kompilierten Klassenvorlage 'boost::slot7<R,T1,T2,T3,T4,T5,T6,T7,SlotFunction>' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(95) : error C2143: Syntaxfehler: Es fehlt ',' vor '&' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(109): Siehe Verweis auf Instanziierung der kompilierten Klassenvorlage 'boost::slot8<R,T1,T2,T3,T4,T5,T6,T7,T8,SlotFunction>' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(95) : error C2143: Syntaxfehler: Es fehlt ',' vor '&' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(109): Siehe Verweis auf Instanziierung der kompilierten Klassenvorlage 'boost::slot9<R,T1,T2,T3,T4,T5,T6,T7,T8,T9,SlotFunction>' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(95) : error C2143: Syntaxfehler: Es fehlt ',' vor '&' ...\thread_safe_signals\boost\thread_safe_signals\detail\slot_template.hpp(109): Siehe Verweis auf Instanziierung der kompilierten Klassenvorlage 'boost::slot10<R,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,SlotFunction>' The same error comes up with other example snippets like doc_view.cpp or something else.

[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.

[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.

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?

newbie ordering question for boost::multi_index::ordered_non_unique
by Kevin McMahon 01 Jun '07

01 Jun '07

I'd like to pop items in my data set ordered by a key, but if the key is identical then ordered in the order I inserted them. Is there a good way to do that? I guess I could make a composite key using an increasing id. -kevin

[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?
by Arno Schoedl 01 Jun '07

01 Jun '07

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

[bind] Convenience operator overloads
by Arno Schödl 01 Jun '07

01 Jun '07

Hello, are there any plans to provide more convenience operator overloads, such as operator! which is already implemented? I don't see any reason why not to overload all operators in that fashion.

[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
by Sudhir Parikh 01 Jun '07

01 Jun '07

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 } }

[Unit Test] default FPC_STRONG limtations when checking close to 0.
by Chris Fairles 01 Jun '07

01 Jun '07

After wondering why my BOOST_CHECK_CLOSE(some_number_close_to_zero, 0.0) hadn't been working, I found that the default comparison type is FPC_STRONG which means the ration between the abs val of the difference and BOTH values must be < tolerance but this doesn't turn out to be true (running through what safe_fpt_division outputs atm ... difference between 0.0{0} and 0.0 std::numeric_limits<double>::epsilon(){-2.2204460492503131e-16} exceeds 0.01% It should work using FPC_WEAK but I can't find a way through the test_tools to easily change this. I have three solutions at this time. 1) Use BOOST_CHECK_SMALL. However, I have code that loops through matrix indicies like: for (int j = 0; j < matrix.col; j++) for (int i = 0; i < matrix.row; i++) BOOST_CHECK_CLOSE(matrix(i,j), data(i,j), tolerance); I'm going to have to use an if statement for the special case where I'm testing against 0 and it doesn't use the tolerance anyway so the test is completely different. Theres another number to determine "how small" the number should be. 2) Use check_is_close explicitly and change the default comparison type to FPC_WEAK. This means going outside the nice auto-unit-test and test-tools framework which although I'm fine with, other programmers writing test cases on my team might not be. 3) Define my own macro to simplify solution 2. Something along the lines of: CHECK_IS_CLOSE_WEAK(x,y,t) { check_is_close(x ,y,t, FPC_WEAK); } Are there any other recommended solutions?
