DLL problems



  • I've created a shared library using Qt Creator( added QtCore and QtGui support ) but when I try to use this dll( I create an instance of a class from that dll ) into another app I'm getting app.exe exited with code -1073741515 at runtime and I don't know what I'm doing wrong.

    I added in my app .pro file the path to the dll:
    LIBS += "E:\Sorin\TestingQt\GUIComponents-build-desktop\debug\GUIComponents.dll"



  • If I'm adding the .dll to my folder app it's working but when I'm specifying the path to it I'm getting the error form above :(



  • Hi,

    I don't think that in your executable the specified path of the DLL will be used. So you should store the DLL together with the executable, or copy it in a directory contained in your PATH environment variable.

    Tony.



  • yes, that's the problem, the exe file doesn't know were to look for my dll, LIBS += path is used only at compile time. Thanks!



  • If you're using Qt Creator, you can modify the PATH to use in the Run environment, adding the path to your DLLs there.
