Typo in boost/graph/properties.hpp
by Janusz Piwowarski 20 Jun '04

Hello, I'm attaching patch, as in subject. Also, there isn't undefined variable x in boost/graph/graph_test.hpp (test_readable_vertex_property_graph and test_vertex_property_graph templates). I have no idea what it is. Regards, Janusz

Dear William E. Kempf, I installed the latest version of the boost-1.31.0 on Win xp pro with vc7.1 and tried to use the thread library. During the first build of several samples, MSVS(vc71) gave me a warning about the errors. However I ignored the errors and select option to proceed(the same result is in other case). It seems to me the samples work correctly in spite of errors and warning located below my message. I had no warning or errors on the next build of the same sample at all. Would you please tell me what is going on? And how do I fix it? Thanks Valery Salamakha VC71_ROOT\include\stdexcept(14): see declaration of 'std::logic_error' c:\Boost\include\boost-1_31\boost\thread\exceptions.hpp(28) : see declaration of 'boost::lock_error' c:\Boost\include\boost-1_31\boost\thread\thread.hpp(78): warning C4251: 'boost::thread_group::m_threads' : class 'std::list<_Ty>' needs to have dll-interface to be used by clients of class 'boost::thread_group' with [ _Ty=boost::thread * ] c:\Boost\include\boost-1_31\boost\thread\mutex.hpp(36): warning C4275: non dll-interface class 'boost::noncopyable' used as base for dll-interface class 'boost::mutex' c:\Boost\include\boost-1_31\boost\noncopyable.hpp(22) : see declaration of 'boost::noncopyable' c:\Boost\include\boost-1_31\boost\thread\mutex.hpp(35) : see declaration of 'boost::mutex' c:\Boost\include\boost-1_31\boost\thread\thread.hpp(38): warning C4275: non dll-interface class 'boost::noncopyable' used as base for dll-interface class 'boost::thread' c:\Boost\include\boost-1_31\boost\thread\thread.hpp(67): warning C4275: non dll-interface class 'boost::noncopyable' used as base for dll-interface class 'boost::thread_group' c:\Boost\include\boost-1_31\boost\noncopyable.hpp(22) : see declaration of 'boost::noncopyable' c:\Boost\include\boost-1_31\boost\thread\mutex.hpp(114): warning C4275: non dll-interface class 'boost::noncopyable' used as base for dll-interface class 'boost::timed_mutex' c:\Boost\include\boost-1_31\boost\noncopyable.hpp(22) : see declaration of 'boost::noncopyable' c:\Boost\include\boost-1_31\boost\thread\mutex.hpp(113) : see declaration of 'boost::timed_mutex' c:\Boost\include\boost-1_31\boost\thread\mutex.hpp(74): warning C4275: non dll-interface class 'boost::noncopyable' used as base for dll-interface class 'boost::try_mutex' c:\Boost\include\boost-1_31\boost\noncopyable.hpp(22) : see declaration of 'boost::noncopyable' c:\Boost\include\boost-1_31\boost\thread\mutex.hpp(73) : see declaration of 'boost::try_mutex' c:\Boost\include\boost-1_31\boost\thread\exceptions.hpp(29): warning C4275: non dll-interface class 'std::logic_error' used as base for dll-interface class 'boost::lock_error' c:\Boost\include\boost-1_31\boost\thread\exceptions.hpp(35): warning C4275: non dll-interface class 'std::runtime_error' used as base for dll-interface class 'boost::thread_resource_error' c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\stdexcept(136) : see declaration of 'std::runtime_error' c:\Boost\include\boost-1_31\boost\thread\exceptions.hpp(34) : see declaration of 'boost::thread_resource_error' __________________________________ Do you Yahoo!?

Where do you hit a problem? The problems arise in the interation with basic_string_impl and how to implement swap and functions that require constructing a string object. Both string_base and fixed_string must operate through basic_string_impl to allow basic_string operations. I suppose this should be done in a heirarchy similar to the current one, having swap virtual (you don't want to swap internal pointers!) and using the current system for the object construction functions, but it may be possible to have substr virtual, I'm not sure yet. I shall have a go at this and report back when I have a working implementation.

Another BoostBook/Doxygen bug?
by Angus Leeming 18 Jun '04

18 Jun '04

Is it possible to get the BoostBook/Doxygen documentation system to include my commentary? This is the header file #include <boost/child/detail/pipe_mode.hpp> namespace boost { namespace child { /// A stateless class providing constants and typenames. struct pipes_base { /// A type used to specify how to communciate with the child process. typedef detail::pipe_mode pipe_mode; /// Write to the child's standard input stream. static const pipe_mode child_stdin = pipe_mode(1); /// Read from the child's standard output stream. static const pipe_mode child_stdout = pipe_mode(2); /// Read from the child's standard error stream. static const pipe_mode child_stderr = pipe_mode(4); /// Redirect the child's stderr to its stdout. static const pipe_mode redirect_child_stderr = pipe_mode(8); /// No pipes are to be used. static const pipe_mode no_pipes = pipe_mode(16); }; } // namespace child } // namespace boost And below is the generated documentation. See how all the descriptions of the constants have dissappeared. Also see how the typedef has been 'modified'. Regards, Angus Struct pipes_base boost::child::pipes_base ? A stateless class providing constants and typenames. Synopsis struct pipes_base { // types typedef unspecified pipe_mode; // A type used to specify how to communciate with the child process. static const pipe_mode child_stdin; static const pipe_mode child_stdout; static const pipe_mode child_stderr; static const pipe_mode redirect_child_stderr; static const pipe_mode no_pipes; };

program_options with mingw

Hello, I attach a patch that allows use of program_options with mingw compiler. There isn't support for utf-8 conversion - maybe it is possible to convert without use of wstring? Regards, Janusz
