MingW compilation errors
I have managed to build the boost libraries with b2 and the gcc toolset option. Alas, whenever I use a header which invokes such a library in Code::Blocks chained with MingW I get these errors: undefined reference to _Unwind_SiLj_Register undefined reference to _Unwind_SiLj_Unregister undefined reference to _Unwind_SiLj_Resume undefined reference to __gxx_personality_sj0 undefined reference to _WSACleanup@0 undefined reference to _WSAStartup@8 All but the last two repeatedly. I would really appreciate anyone who could point me out of this mess. Thanks!

It has probably to do with sjlj exceptions in g++. Personnaly I build my own mingw cross compiler (linux->windows) with the following option: --disable-sjlj-exceptions. Otherwise, I can get that sort of issues. But then, I build boost with the cross compiler on linux. The toolset is gcc, not mingw. I can still use the libraries on windows with CodeBlocks. My command line for b2 is: ./b2 --layout=system --user-config=user-config.jam link=static theading=multi runtime-link=shared target-os=windows threadapi=win32 variant=release install with user-config.jam containing: using gcc : : i686-pc-mingw32-g++ : <compileflags>-DBOOST_THREAD_USE_LIB ; Hope this can help you. Cheers, Frédéric

These errors suggest that the boost libraries were compiled with a different version of gcc than the code that is trying to use them. Check which gcc version you used to build the boost libraries, and make sure that Code::Blocks is configured to use the same gcc version.

These errors suggest that you need to link your program to the winsock32 library. On the command line you would do this by adding the flag "-lws2_32" to the linker command. I'm not familiar with Code::Blocks, but presumably there is a dialog somewhere where you can specify linker options. Regards, Nate
