macdeployqt - Missing dependancies when installing.

  • I created an application which runs in Qt creator.
    Using macdeployqt to make an installer; once installed on another Mac, I get the following error trying to execute the application :

    Library not loaded: @rpath/QtWidgets.framework/Versions/5/QtWidgets

    I really need to deploy this asap.

    Thank you.

    Hi and welcome to devnet,

    What version of Qt ?
    On what version of macOS ?
    What parameters did you pass to macdeployqt ?

  • I am using Qt v5.8 on OS X 10.11.6.

    I simply used :

    macdeployqt -dmg

    from the release directory.

    Thank you.

    Might be a silly question but do you have several version of Qt installed ? If so, which version of macdeployqt are you using ?

  • @SGaist No, I only have v5.8 and the macdeployqt that came with it.

    Thank you.

    Can you share your .pro file ?

    Can you show the result of otool -L on your application ?

    What does the Frameworks folder contain ?

    Also, what parameters are you passing to macdeployqt ?

  • i had a similar problem,
    in my case the deps were succesfully deployed to the qt but the application still could not find them,
    (they should be in

    if your issue is similar, you could try
    compiling with this flag, which will create an rpath to the frameworks folder

    QMAKE_LFLAGS += -Wl,-rpath,@executable_path/../Frameworks

    or to fix current version without recompile you could try editing current rpath

    install_name_tool -add_rpath "@executable_path/../Frameworks"

  • @chips-and-fish Thank you so much ! That fixed it.
    Although I am a bit surprised as the path to Framework is an artifact of macdeployqt; one would think it would automatically add it...
