    Hi,

    I'm no longer able to load my Steam plugin with the way it worked in 5.15 on macOS. It does still work on Windows. I created a qml plugin that gets loaded on runtime that needs the libsteam_api.dylib. Previously placing the libsteam_api.dylib beside the plugin worked fine.

    // This fixed the plugin loading in 5.15
 m_mainWindowEngine->addPluginPath(QGuiApplication::instance()->applicationDirPath());
// Does also not work when adding: 
m_mainWindowEngine->addPluginPath(QGuiApplication::instance()->applicationDirPath() + "/Workshop");

    Now it ony works on macOS when placing the libsteam_api.dylib besides the .app file.

    "qrc:/ScreenPlay/qml/Workshop/SteamWorkshop.qml:6:1:

      Hi,

      Shouldn't that library be stored in the Frameworks sub folder and then its search path be set to @rpath/../Frameworks ?

        @SGaist thanks for the anweser, but none of that worked.

            m_mainWindowEngine->addPluginPath(QGuiApplication::instance()->applicationDirPath());
    m_mainWindowEngine->addPluginPath(QGuiApplication::instance()->applicationDirPath()+"/../Frameworks");
    m_mainWindowEngine->addPluginPath("@rpath/../Frameworks");
    m_mainWindowEngine->addImportPath("@rpath/../Frameworks");
    m_mainWindowEngine->addImportPath(QGuiApplication::instance()->applicationDirPath());
    m_mainWindowEngine->addImportPath(QGuiApplication::instance()->applicationDirPath()+"/../Frameworks");

    qInfo() << m_mainWindowEngine->pluginPathList();
    qInfo() << m_mainWindowEngine->importPathList();
    qInfo() <<  QGuiApplication::instance()->libraryPaths();

        printing:

        "QList(\"\", \"/Users/eli/Documents/build-ScreenPlay-ScreenPlay_Qt_6_2_1_clang_64bit-Release/bin/ScreenPlay.app/Contents/Frameworks\", \"/Users/eli/Documents/build-ScreenPlay-ScreenPlay_Qt_6_2_1_clang_64bit-Release/bin/ScreenPlay.app/Contents/MacOS\", \".\")"
"QList(\"/Users/eli/Documents/build-ScreenPlay-ScreenPlay_Qt_6_2_1_clang_64bit-Release/bin/ScreenPlay.app/Contents/Frameworks\", \"/Users/eli/Documents/build-ScreenPlay-ScreenPlay_Qt_6_2_1_clang_64bit-Release/bin/ScreenPlay.app/Contents/MacOS\", \"qrc:/qt-project.org/imports\", \"/Users/eli/Qt/6.2.1/macos/qml\")"
"QList(\"/Users/eli/Qt/6.2.1/macos/plugins\", \"/Users/eli/Documents/build-ScreenPlay-ScreenPlay_Qt_6_2_1_clang_64bit-Release/bin/ScreenPlay.app/Contents/MacOS\")"

        I now copied the files in every folder like:

        • /ScreenPlay.app/Contents/MacOS\
        • /ScreenPlay.app/Contents/MacOS\Workshop
        • /ScreenPlay.app/Contents/Framworks\Workshop

        It only works if I place the third party dylib besides ScreenPlay.app location. This is only since my upgrade to Qt 6.2

        Content of the Workshop folder:

        ScreenPlayWorkshop.qmltypes
libScreenPlayWorkshop.dylib
libScreenPlayWorkshopplugin.dylib
libsteam_api.dylib # <- Only works if this file is in the same folder as ScreenPlay.app
libScreenPlayWorkshopplugin.a
libSteamSDK.a
qmldir

        When loading the qml plugin:

        "qrc:/ScreenPlay/qml/Workshop/SteamWorkshop.qml:6:1: Die Bibliothek /Users/eli/Documents/build-ScreenPlay-ScreenPlay_Qt_6_2_1_clang_64bit-Release/bin/ScreenPlay.app/Contents/MacOS/Workshop/libScreenPlayWorkshopplugin.dylib kann nicht geladen werden: (dlopen(/Users/eli/Documents/build-ScreenPlay-ScreenPlay_Qt_6_2_1_clang_64bit-Release/bin/ScreenPlay.app/Contents/MacOS/Workshop/libScreenPlayWorkshopplugin.dylib, 0x0085): Library not loaded: @rpath/libScreenPlayWorkshop.dylib\n  Referenced from: /Users/eli/Documents/build-ScreenPlay-ScreenPlay_Qt_6_2_1_clang_64bit-Release/bin/ScreenPlay.app/Contents/MacOS/Workshop/libScreenPlayWorkshopplugin.dylib\n  Reason: tried: '/Users/eli/Documents/build-ScreenPlay-ScreenPlay_Qt_6_2_1_clang_64bit-Release/bin/libScreenPlayWorkshop.dylib' (no such file),

          Did you use macdeployqt on your app bundle ?

              @QKelteseth in the terminal, please navigate inside your bundle where the main executable resides (ScreenPlay.app/Contents/MacOS) and run otool -L <your_exe_name> - this will print you what shared libraries are linked to that executable and where do they are expected.

              You should run macdeployqt also when using qml (if in doubt run macdeployqt --help).

              if you need to adjust linked paths in your executable in the macOS folder of your bundle then the tool install_name_tool is your friend.

              For more information please re-read.

              Kind Regards,
              Artur

                @QKelteseth said in MacOS dylib plugin loading path changes from Qt 5.15 to Qt 6.2:

                @SGaist isn't macdeployqt only for qt libraries?

                It is to be used when you want to prepare your app bundle for deployment.

                  @artwaw @SGaist I think it works now if I place it in the root Frameworks folder. Using ottol on the lib printed:

                  Load command 12
          cmd LC_LOAD_DYLIB
      cmdsize 56
         name @loader_path/libsteam_api.dylib (offset 24)
   time stamp 2 Thu Jan  1 01:00:02 1970
      current version 1.0.0
compatibility version 1.0.0
Load command 13
          cmd LC_LOAD_DYLIB
      cmdsize 72
         name @rpath/QtQuick.framework/Versions/A/QtQuick (offset 24)
   time stamp 2 Thu Jan  1 01:00:02 1970
      current version 6.2.1
compatibility version 6.0.0
Load command 14

                  Thanks for your help! Have a great weekend <3
