    Question Qt + boost + MinGW on Windows

    I'm trying to create a build environment which would include Qt 4.3 and boost 1.35.0 on both Linux and Windows, using Eclipse CDT as a common IDE on both platforms. On Linux things are quite straighforward, one just installs Eclipse CDT, the Qt-Eclipse integration plugin, and then everything compiles and links fine with the system supplied gcc and system installed boost libraries.

    But on Windows, I'm getting into issues. There I also downloaded Eclipse CDT, the Qt-Eclipse integration pluign, Qt itself, which in turn downloads a specific version of MinGW it likes. I can import and compile the source code samples that come with Qt with this setup.

    But I'm having trouble integration boost into the mix. I tried several approaches.

    Trying to link boost that was compiled for Visual C++

    First I downloaded the binary boost package compiled for Windows from Boost Consulting. It installs fine, and if I add the appropriate directory the include files are found. But, I can't link to any of the boost libraries provided, even if I supply the library path and the name of the library appropriately in the project file as:

    LIBS+= -Lc:\usr\boost\boost_1_35_0\lib -lboost_date_time-vc90-mt-1_35

    seemingly the symbols that are supposed to be in the library are not found by the MinGW linker:

    Qt Code: 
    1. g++ -enable-stdcall-fixup -Wl,-enable-auto-import
    2. -Wl,-enable-runtime-pseudo-reloc -Wl,-s -mthreads -Wl
    3. -Wl,-subsystem,windows -o release\hello_boost_opengl.exe
    4. release/BoostTime.o release/GlWidget.o release/main.o release/MainWindow.o
    5. release/moc_GlWidget.o release/moc_Mainwindow.o  -L"c:\usr\Qt\4.3.5\lib"
    6. -lopengl32 -lglu32 -lgdi32 -luser32 -lmingw32 -lqtmain
    7. -lboost_date_time-vc80-mt-1_35 -Lc:\usr\boost\boost_1_35_0\lib -lQtOpenGL4
    8. -lQtGui4 -lQtCore4
    9. release/BoostTime.o(.text$_ZN5boost9gregorian21to_simple_string_typeIcEESbIT_St11char_traitsIS2_ESaIS2_EERKNS0_4dateE[std::basic_string<char,

    12. const&)]+0x1b3):BoostTime.cpp: undefined reference to
    13. `boost::gregorian::greg_month::as_short_string() const'
    14. collect2: ld returned 1 exit status
    To copy to clipboard, switch view to plain text mode 

    Trying to use MinGW from nuwen.net

    As an alternative approach, I tried using the MinGW distribution from nuwen.net, which conveniently contains boost as it is. But it seems that one can't really link Qt against this MinGW distribution, as I get:

    Qt Code: 
    1. g++ -enable-stdcall-fixup -Wl,-enable-auto-import
    2. -Wl,-enable-runtime-pseudo-reloc -Wl,-s -mthreads -Wl
    3. -Wl,-subsystem,windows -o release\hello_boost_opengl.exe
    4. release/BoostTime.o release/GlWidget.o release/main.o release/MainWindow.o
    5. release/moc_GlWidget.o release/moc_Mainwindow.o  -L"c:\usr\Qt\4.3.5\lib"
    6. -lopengl32 -lglu32 -lgdi32 -luser32 -lmingw32 -lqtmain
    7. -lboost_date_time-vc80-mt-1_35 -Lc:\usr\boost\boost_1_35_0\lib -lQtOpenGL4
    8. -lQtGui4 -lQtCore4
    9. release/BoostTime.o:BoostTime.cpp:(.text$_ZN5boost9date_time14date_formatterINS_9gregorian4dateENS0_13simple_formatIcEEcE14date_to_stringES3_[boost::date_time::date_formatter<boost::gregorian::date,
    10. boost::date_time::simple_format<char>,
    11. char>::date_to_string(boost::gregorian::date)]+0x1f0): undefined reference
    12. to `boost::gregorian::greg_month::as_short_string() const'
    13. c:\usr\Qt\4.3.5\lib/libqtmain.a(qtmain_win.o):qtmain_win.cpp:(.text+0x26):
    14. undefined reference to `___gxx_personality_sj0'
    15. c:\usr\Qt\4.3.5\lib/libqtmain.a(qtmain_win.o):qtmain_win.cpp:(.text+0x39):
    16. undefined reference to `__Unwind_SjLj_Register'
    17. c:\usr\Qt\4.3.5\lib/libqtmain.a(qtmain_win.o):qtmain_win.cpp:(.text+0x255):
    18. undefined reference to `__Unwind_SjLj_Unregister'
    19. c:\usr\Qt\4.3.5\lib/libqtmain.a(qtmain_win.o):qtmain_win.cpp:(.text+0x32c):
    20. undefined reference to `__Unwind_SjLj_Resume'
    21. collect2: ld returned 1 exit status
    To copy to clipboard, switch view to plain text mode 


    maybe the next approach would be to use the MinGW version that is downloaded by Qt, get MSYS, and compile it manually. I wonder if there's a binary downloadable version of boost that can be used out of the box with Qt and MinGW

    All help is appreciated

    1. You can't mix msvc and mingw c++ libs - so your first approach doesn't work
    2. You can't also mix gcc3 and gcc4 which looks like your second problem

    So oyu have to compile boost by your own - but why do you want to use msys for this? bjam works on cmd.exe fine too.

    I wasn't sure about this, so thanks for the clarification

    ah, you mean that Qt itself was compiled againts gcc3, and now I'm trying to use gcc4, and therefore it doesn't work... but then again, I could try compiling Qt with gcc4. hm...

    I used an msys prompt because I'm more familiar with UNIX prompts

    but, actually trying to run bjam from a Windows Command Prompt give me errors (trying with MinGW that is downloaded and installed by Qt itself)

    The last time I tried the bjam monster (and was then happy that I only use cmake by myself) it worked fine. But it was some time ago...
    And yes - you can't link qt4/gcc3 against app/gcc4 and vice versa as the ABI changed there too afaik.
