    Default xerces - undefined reference

    Hi, I'm using xerces with QT...I've installed xerces-c package (gentoo linux), but here are the problems while linking:

    Qt Code: 
    1. eleanor-laptop client # /sources/qt/bin/qmake && make && ./client
    2. g++ -Wl,-rpath,/sources/qt/lib -o client attach_file.o clientGui.o main.o sslClient.o moc_attach_file.o moc_clientGui.o moc_sslClient.o qrc_resources.o    -L/sources/qt//lib -lQtXml -L/sources/qt//lib -pthread -pthread -lQtGui -L/usr/X11R6/lib -pthread -lpng -lfreetype -lgobject-2.0 -lSM -lICE -pthread -pthread -lXrender -lfontconfig -lXext -lX11 -lQtNetwork -pthread -pthread -lQtCore -lz -lm -pthread -lgthread-2.0 -lrt -lglib-2.0 -ldl -lpthread

    Does anybody have any idea what am I missing here? The libraries are installed and the #include directives are processed (found) without a problem.

    You have to LINK Xerces libraries.

    Try to Insert
    Qt Code: 
    1. LIBS += -L<path_to_xercers_libs> -lxerces-c
    To copy to clipboard, switch view to plain text mode 
    in .pro file

    Thank you very much, it's working...

    Can you point me to a tutorial about this stuff, so I'll never make the same mistake again? (I'm only interested in how to pass libraries in qmake...I don't have problems with g++)

    I suggest you to read qmake documentation.
    In general you must use INCLUDEPATH and LIBS to set flags as "-I", "-L" and "-l"
