    I checked all the frameworks and plugins, nothing was referencing my local Qt on my system, that's why I think it's weird.

      Did you also check what

      @DYLD_PRINT_LIBRARIES=1./MyDirectory/Myapp.app/Contents/MacOS/Myapp@

      returns ?

        It seems macdeployqt tool didn't copy libqcorewlanbearer.dylib and libqgenericbearer.dylib files into the bundle, now I did that by hand and changed their dependency, but how to tell the app to use the .dylib files in the bundle

          You seem to also have the platforms plugins loaded from your installed Qt

            yeah,
            1) macdeployqt tool copied platforms plugins into the bundle,but my app still loaded them from my installed Qt
            2)macdeployqt tool didn’t copy libqcorewlanbearer.dylib and libqgenericbearer.dylib files into the bundle

            so it's qt's bug? how to fix it ? I have copied libqcorewlanbearer.dylib and libqgenericbearer.dylib files into the bundle by hand and changed their dependency, how to make my app load the .dylib files in the bundle ?

              I would go with otool on each and every library and verify that the dependencies all point to @executable_path/../Frameworks/THE_Qt_FRAMEWORK and also verify the library IDs

                Thanks for your advice, but the point is frameworks and executable flag don't reference the plugins directly , so how can i know which one is referencing the plugins? I think my app loads right frameworks but wrong plugins. and otool can get information of frameworks reference only

                  That's what DYLD_PRINT_LIBRARIES=1 helps you find, you can also guess a bit knowing what you are using in your software (image formats, printing, networking etc…)

                    well, let me describe it in this way,
                    all the plugins my app needs are in the bundle, but app still loads the plugins installed on my system at run-time. And thanks again for your patience.

                      for example, libqcorewlanbearer.dylib is in the bundle, the following is the "otool -L" information

                      but when I use "DYLD_PRINT_LIBRARIES=1", I find the app loaded a wrong libqcorewlanbearer.dylib and its dependencies.

                        Ok… There might be something funky with qt.conf's usage, I tried to start your application setting QT_PLUGIN_PATH to point to your bundle plugin path and it's working fine.

                        Have a look at the Mac Deployment Documentation, they explain how to add the path to the bundle plugin directory when starting your application, that should workaround your current problem

                          I have viewed the docment, and I think the content of my qt.conf file is right, it does point to my bundle plugin path. : (

                            I think it is (or at least I don't see any reason right now that it would not be)

                            That's why I suggested to use the addLibraryPath() technique in between

                              then I added the following code to main.cpp, didn't work at all.

                              QDir dir(QApplication::applicationDirPath());

                              qDebug()<<dir.absolutePath();

                                And if you use setLibraryPath ?

                                  Like this? it doesn't work either.

                                  QDir dir(QApplication::applicationDirPath());
                                  qDebug()<<dir.absolutePath();
                                  dir.cdUp();
                                  qDebug()<<dir.absolutePath();
                                  dir.cd("PlugIns");
                                  qDebug()<<dir.absolutePath();
                                  QApplication::setLibraryPaths(QStringList(dir.absolutePath()));

                                    And we shouldn't forget this, maybe it's a important clue.
                                    the macdeployqt tool even didn't copy the plugins into the bundle at the first time, I did this by hand. And later the app loaded them incorrectly no matter how I modify the Path in qt.conf file or in source code.

                                      In between, did you update to 5.2 since it's been officially released ?

                                          how do you set QT_PLUGIN_PATH ? show me plz.
                                          [quote author="SGaist" date="1387459417"]Ok… There might be something funky with qt.conf's usage, I tried to start your application setting QT_PLUGIN_PATH to point to your bundle plugin path and it's working fine.

                                          Have a look at the Mac Deployment Documentation, they explain how to add the path to the bundle plugin directory when starting your application, that should workaround your current problem[/quote]
