How to execute complex project on RPi Linux



  • I have a complex project where sub portions of the project are done as .so files with the directory structure like this

    MainDir
        build-dir
            MainProj
            sub1
            sub2
            sub3
            ...
        ProjectDir
            MainProj
            sub1
            sub2
            sub3
            ...
    

    In the .pro file for the main project the .so's are included with:
    INCLUDEPATH += $PWD/../sub1
    DEPENDPATH += $PWD/../sub1

    I can't figure out how to get the project to execute from the command line. If I change to the build directory for the main executable and try to run it there I get an error:
    ./MainProj: error while loading shared libraries: libSub1.so.1: cannot shared object file: No such file or directory
    I've tried executing from the directory that MainProj is built in, I tried copying the MainProj executable and all of the .so's to a single directory an I get the same error.
    Can anybody help me figure how to execute this project from the command line, it runs properly from inside Qt Creator.



  • I talked to some QT people at SigGraph and they suggested that I dump the environment variables which turned out to be a good suggestion. QtCreator builds a LD_LIBRARY_PATH variable that includes paths to all of the libraries for the sub projects.
