Linux/QtCreator/static-dynamic lib linking



  • dear colleagues, i need help

    I've got really weird problem and don't know how to resolve it.

    I've made the static library. This library contains algorithms for working with gconf-client. Library works only with using *.so objects. I wrote full path to each of necessarily *.so files in *.pro file.

    @LIBS += /home/xray/LibraryLoader/liblibraryloader.a -ldl
    /usr/lib/libgconf2-4/2/libgconfbackend-evoldap.so
    /usr/lib/libgconf2-4/2/libgconfbackend-oldxml.so
    /usr/lib/libgconf2-4/2/libgconfbackend-xml.so@

    The program has successfully built but had problems with start.
    I've got this message:
    @/home/xray/testLibs-build-desktop/testLibs: error while loading shared libraries: libgconfbackend-evoldap.so: cannot open shared object file: No such file or directory@

    So, I've decided to set a variable LD_LIBRARY_PATH=/usr/lib/libgconf2-4/2/

    After that, I built the program again and then tried to start. I've got this:

    @Starting /home/xray/testLibs-build-desktop/testLibs...
    *** glibc detected *** /home/xray/testLibs-build-desktop/testLibs: malloc(): memory corruption: 0x09ab7900 ***

    The program has unexpectedly finished.
    /home/xray/testLibs-build-desktop/testLibs exited with code 0@

    When I'm trying to start program in debug mode and go step by step, I get the exception at this line of code:
    g_type_init(); // initialization of gconf api

    This is the first call of function located in *.so object. It seems to me that body of function located in *.so was not loaded.
    I will appreciate all useful advices.
    Thanks in advance.

    You might have better luck asking in a gnome forum about this: This seems a gconf related issue which is not widely used in the Qt camp:-)

    Does gconf support being build statically at all?



  • before using QT I compiled console application with this static library in NetBeans IDE. Program has started and implemented successfully. :)

    so... i should try to get luck somewhere else. thx)

    but still in hope)
