Using Boost With QtCreator?



  • I have been able to use <boost/filesystem> in Visual studio no problem but have had trouble getting it to work in QtCreator.

    I first tried putting in my .Pro file

    INCLUDEPATH += C:\boost\include\boost-1_59
    LIBS += "-LC:\boost\boost_1_59_0\stage\lib"

    and get error
    C:\boost\include\boost-1_59\boost\system\error_code.hpp:221: error: undefined reference to `boost::system::generic_category()'

    C:\boost\include\boost-1_59\boost\system\error_code.hpp:222: error: undefined reference to `boost::system::generic_category()'

    C:\boost\include\boost-1_59\boost\system\error_code.hpp:223: error: undefined reference to `boost::system::system_category()'
    collect2.exe:-1: error: error: ld returned 1 exit status

    I looked around online and found some mention of problems like this but still couldn't get it to work.

    I tried changing the .pro file to have

    INCLUDEPATH += C:\boost\include\boost-1_59
    LIBS += "-LC:\boost\boost_1_59_0\stage\lib" -llibboost_filesystem-vc140-mt-1_59

    And still get the same errors

    Any help is appreciated

    You should not use the "lib" prefix and the version string is probably not needed as well (but try with that string if it doesn't work without), so it should be:
    LIBS += "-LC:\boost\boost_1_59_0\stage\lib" -lboost_filesystem

    One more thing to consider: Boost libraries must be built using the same compiler you use to build your project!

    So think I got it figured out. I went back and recompiled the libraries with MSVC 2010 which is what I am using with Qt.

    now my pro file looks like

    INCLUDEPATH += C:\boost\boost_1_59_0\boost-dir\include
    LIBS += -L"C:\boost\boost_1_59_0\boost-dir\lib" -lboost_filesystem-vc100-mt-1_59
    

    which builds fine. Posting this for future people stumbling down the same path.
