    Hi guys

    I have written a code which needs some .so libs.
    My code is working perfectly on QT creator but when I am trying to run the same using the exe generated and required libs it is throwing this error

    error while loading shared labraries: libAECOSLib.so: cannot open shared object file: No such file or directory

    I tried couple of things like :

    QMAKE_LFLAGS += "-W1, -rpath,$$ORIGIN" in my pro file.
    but it is throwing error unrecognized command '-W1', '-rpath'

    I have included libs in this way :
    unix:!mac: LIBS += -L./IMI_Libraries/ -lARCOSLib

    when I am setting the path using terminal it is working

    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path to IMI Libraries

    But I want that it should be handled through pro file.

    How can I Solve this problem?

    Thanks
    Ashish

      You can write a shell script where you set LD_LIBRARY_PATH and then call your executable. Then use that script to start your app.

        Hi @jsulm
        Thanks for the help !!!

        Is there any solution if I want to set this path in .pro file itself. I mean how can I make my executable to search for libs in the same folder by adding some paths in .pro file so that I can just run my executable on any system without using shell script or without setting LD_LIBRARY_PATH in terminal.

          @ashajg You can use https://doc.qt.io/qt-5/qmake-variable-reference.html#qmake-rpathdir
