Janusz, I'm using version 3.1.0-1 of mingw (its basically the current release that you can download at www.mingw.org) THanks, Alex PS.

Newbie: What is the actual return type?
by Tim Rowe 20 Jun '04

20 Jun '04

In the Kevin Bacon example in the Boost::Graph documentation, we declare: typedef adjacency_list < vecS, vecS, undirectedS, property < vertex_name_t, std::string >, property < edge_name_t, std::string > > Graph; Graph g; and later declare and call: typedef property_map < Graph, vertex_name_t >::type actor_name_map_t; actor_name_map_t actor_name = get(vertex_name, g); What are we actually getting back here? I can see that we can index it (we do later), but is it just an array? Or a vector? Or what? I assume I am /supposed/ to know (not like Ada's "type foo is private"), so that I know what I can do with it! TIA, Tim Rowe

Hi, I have encountered similar problem that you solved after "some fiddling". Can you specify what exactly you did to successfully compile Boost.Python?

Hi All, I have a problem in compiling my very first example in BGL - quick_tour.cpp, using boost-1_31, VC 6.0 and native Microsoft stl. I've got the following error messages: c:\boost\include\boost-1_31\boost\graph\detail\adjacency_list.hpp(1055) : error C2244: 'bidirectional_graph_helper_with_property<Config>::remove_edge' : unable to resolve function overload c:\boost\include\boost-1_31\boost\graph\detail\adjacency_list.hpp(1057) : error C2954: template definitions cannot nest c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(45) : error C2143: syntax error : missing ';' before '<' c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(57) : see reference to class template instantiation 'is_incrementable_::impl<T>' being compiled c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(45) : error C2059: syntax error : '<' c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(57) : see reference to class template instantiation 'is_incrementable_::impl<T>' being compiled c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(45) : error C2039: 'type' : is not a member of '`global namespace'' c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(57) : see reference to class template instantiation 'is_incrementable_::impl<T>' being compiled c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(45) : error C2238: unexpected token(s) preceding ';' c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(57) : see reference to class template instantiation 'is_incrementable_::impl<T>' being compiled c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(52) : error C2653: 'mpl' : is not a class or namespace name c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(57) : see reference to class template instantiation 'is_incrementable_::impl<T>' being compiled c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(52) : error C2143: syntax error : missing ';' before '<' c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(57) : see reference to class template instantiation 'is_incrementable_::impl<T>' being compiled c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(52) : error C2059: syntax error : '<' c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(57) : see reference to class template instantiation 'is_incrementable_::impl<T>' being compiled c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(56) : error C2238: unexpected token(s) preceding ';' c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(57) : see reference to class template instantiation 'is_incrementable_::impl<T>' being compiled c:\boost\include\boost-1_31\boost\detail\is_incrementable.hpp(69) : fatal error C1903: unable to recover from previous error(s); stopping compilation My question is : May I use BGL 1_31 using VC6.0 with all restrictions of VC6.0 compiler? Thanks a lot for your advice, Kagan Boris.

INI File Parser?
by Duane Murphy 18 Jun '04

18 Jun '04

A while back, I noted that there was an INI file parser as part of boost. It was obscure, but I think it was in the program_options library. I note references to program_options searching the web site, but I'm not finding anything in the latest builds. I'm specifically interested in parsing INI files (I'm on a Macintosh) but the program_options library also seemed interesting. Is there anything available? What's the status of the program_options library? Thanks for any pointers, ...Duane

Newbie question -- graph library example

In the example examples/file_dependencies.cpp, I can't see what either of the typedefs for Color do: typedef property_map<Graph,vertex_color_t>::type Color; If I comment then out everything seems still to work. What are they there for? TIA, Regards, Tim

[Tuple] broken for gcc-3.4.0
by Jürgen Hunold 17 Jun '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi ! After updating my cvs snapshot at 12.15 , the tuple library is broken for gcc 3.4.0. My own program stopped compiling and when going to libs/tuple/test and running bjam I get: In file included from /ive/hunold/packages/boost/boost/tuple/tuple.hpp:38, from ../../../libs/tuple/test/tuple_test_bench.cpp:19: /ive/hunold/packages/boost/boost/tuple/detail/tuple_basic.hpp: In function `typename boost::tuples::access_traits<typename boost::tuples::element<N, boost::tuples::cons<HT, TT> >::type>::non_const_type boost::tuples::get(boost::tuples::cons<HT, TT>&)': /ive/hunold/packages/boost/boost/tuple/detail/tuple_basic.hpp:212: error: `get_class' undeclared (first use this function) (full output of failing tests attached) So I think this is really something which gcc 3.4.0 does no handle.

boost::filesystem::path corruption
by Stuart Bingë 17 Jun '04

17 Jun '04

Hello all, I've recently started using some of the Boost libraries, one of which being boost::filesystem. I have however encountered a problem while using the library, which as far as I can tell is a bug. I'm not sure if anyone is aware of this problem, or if is not an issue with the library itself but rather with my configuration - in either case a description of the problem follows: Whenever I instantiate a boost::filesystem::path object and try to print out a text representation of the path using a method such as .string(), the path itself is printed out, however it looks as though the string is not terminated properly as a whole bunch of trailing garbage appears after the path. The following sample program produces the problem for me: #include <iostream> #include <boost/filesystem/path.hpp> int main(int c, char** v) { boost::filesystem::path testpath("test/path"); std::cout << testpath.native_file_string() << std::endl; return 0; } When I run this code I get output similar to the following: test/pathpÿÿÿÿtest/ÿÿÿÿdataÿÿÿÿpath... etc (a whole bunch of other random stuff like days of the week & month, as well as garbage character strings) Can anyone shed some light on this for me? I'm running boost version 1.31.0 on Gentoo Linux x86 (kernel 2.6.5-gentoo-r1) with GCC version 3.3.2, for anyone who is interested. Regards, Stuart Bingë
