Hi there, does anyone could say me how can I compile Boost.Filesystem with MinGW: Is something wrong with my b2-call see below, or is my project-config.jam buggy? ========================= import option ; using gcc ; using python : 2.7 # version : E:/Programme/Python27 # cmd-or-prefix : E:/Programme/Python27/include # includes : E:/Programme/Python27/libs # libraries ; using mpi : : <find-static-library>mpi <library-path>"E:/Programme/MPICH2/lib" <include>"E:/Programme/MPICH2/include" : "\"E:\\Programme\\MPICH2\\bin\\mpiexec\"" ; option.set keep-going : false ; ========================== g++ (GCC) 3.4.2 (mingw-special) Copyright (C) 2004 Free Software Foundation, Inc.

I got as error message for Boost.Filesystem: ./boost/filesystem/v3/config.hpp:49:5: #error Configuration not supported: Boost.Filesystem V3 and later requires std::wstring support That means Boost.Filesystem V2 should work? Can I compile it without other boost things? I run set BUILDPATH=G:/Downloads/Libraries/boost_1_47_0/ownbuild set INSTALLPATH=G:/Downloads/Libraries/boost_1_47_0/distrib b2 --prefix=%INSTALLPATH%/libs/boost-1.47.0/distrib ^ --toolset=gcc ^ --build-dir=%BUILDPATH% ^ --layout=versioned ^ --variant=debug,release ^ --runtime-link=static ^ --link=shared,static ^ --threading=multi ^ --without-mpi ^ --without-python stage >build.log 2>&1 And in build.log I found many errors after waiting some Minutes: ...failed updating 26 targets... ...skipped 30 targets... ...updated 842 targets... If I doesn't use the options --without-mpi --without-python than about 30 seconds later I got this output in build.log: ====================== G:/Downloads/Libraries/boost_1_47_0/tools/build/v2/build\virtual-target.jam:1079: in virtual-target.register-actual-name from module virtual-target error: Duplicate name of actual target: <pstage\lib>mpi.pyd error: previous virtual target { common%common.copy-mpi.pyd.PYTHON_EXTENSION { gcc%gcc.link.dll-mpi.pyd.PYTHON_EXTENSION { gcc%gcc.compile.c++-python\collectives.o.OBJ { python/collectives.cpp.CPP } } { [...] error: created from ./stage-proper error: added properties: <debug-symbols>off <define>NDEBUG <inlining>full <library>object(file-target)@4418 <library>object(file-target)@4420 <library>object(file-target)@4488 <library>object(file-target)@4490 <library>object(file-target)@4602 <library>object(file-target)@4604 <library>object(file-target)@4617 <library>object(file-target)@4619 <library>object(searched-lib-target)@4507 <optimization>speed <runtime-debugging>off <variant>release <xdll-path>/G:/Downloads/Libraries/boost_1_47_0/ownbuild/boost/bin.v2/libs/mpi/build/gcc-mingw-3.4.2/release/threading-multi <xdll-path>/G:/Downloads/Libraries/boost_1_47_0/ownbuild/boost/bin.v2/libs/python/build/gcc-mingw-3.4.2/release/threading-multi <xdll-path>/G:/Downloads/Libraries/boost_1_47_0/ownbuild/boost/bin.v2/libs/serialization/build/gcc-mingw-3.4.2/release/threading-multi error: removed properties: <debug-symbols>on <inlining>off <library>object(file-target)@2472 <library>object(file-target)@2474 <library>object(file-target)@2542 <library>object(file-target)@2544 <library>object(file-target)@2656 <library>object(file-target)@2658 <library>object(file-target)@2671 <library>object(file-target)@2673 <library>object(searched-lib-target)@2561 <optimization>off <runtime-debugging>on <variant>debug <xdll-path>/G:/Downloads/Libraries/boost_1_47_0/ownbuild/boost/bin.v2/libs/mpi/build/gcc-mingw-3.4.2/debug/threading-multi <xdll-path>/G:/Downloads/Libraries/boost_1_47_0/ownbuild/boost/bin.v2/libs/python/build/gcc-mingw-3.4.2/debug/threading-multi <xdll-path>/G:/Downloads/Libraries/boost_1_47_0/ownbuild/boost/bin.v2/libs/serialization/build/gcc-mingw-3.4.2/debug/threading-multi G:/Downloads/Libraries/boost_1_47_0/tools/build/v2/build\virtual-target.jam:490: in actualize-no-scanner from module object(file-target)@5073 G:/Downloads/Libraries/boost_1_47_0/tools/build/v2/build\virtual-target.jam:135: in object(file-target)@5073.actualize from module object(file-target)@5073 G:/Downloads/Libraries/boost_1_47_0/tools/build/v2\build-system.jam:749: in load from module build-system G:\Downloads\Libraries\boost_1_47_0\tools\build\v2/kernel\modules.jam:283: in import from module modules G:\Downloads\Libraries\boost_1_47_0\tools\build\v2\kernel\bootstrap.jam:142: in boost-build from module G:\Downloads\Libraries\boost_1_47_0\boost-build.jam:17: in module scope from module ============================== Please, can any one help me?
