    What plugins are you using ?

    As for the crash report, you should get a dialog automatically after the crash.

    What happens if you call "open your_app.app" on the command line ?

      @SGaist It's a plugin i wrote myself for my application.
      I'm actually calling open <path_to_app> and nothing is printed out to the console.
      If i load the plugin, the application just closes.

        Start your application with the QT_DEBUG_PLUGINS environment variable set to 1. It will show you what is happening with your plugin.

              @SGaist Hi! yes, i can show all my code. In fact, both plugin and application are open source:

              https://github.com/azagaya/laigter
              https://github.com/azagaya/LaigterNormalBrushPlugin

              The revelant part of the app that loads the plugin, is on mainwindow.cpp:

              void MainWindow::on_actionLoadPlugins_triggered()
{
  QString appData =
    QStandardPaths::writableLocation(QStandardPaths::AppDataLocation);
  QDir dir(appData);
  dir.cd("plugins");
  const auto entryList = dir.entryList(QDir::Files);
  foreach (QDockWidget *dock, plugin_docks_list){
    plugin_docks_list.removeOne(dock);
    delete dock;
  }
  foreach (QAction *action, ui->pluginToolBar->actions()){
    if (action->text() == tr("Load Plugins") || (action->text() == tr("Install Plugin"))) continue;
    ui->pluginToolBar->removeAction(action);
  }
  for (const QString &fileName : entryList) {
    QPluginLoader pl(dir.absoluteFilePath(fileName));
    BrushInterface *b = qobject_cast<BrushInterface *>( pl.instance());
    qDebug() << pl.errorString();
    if(b != nullptr){
      ui->openGLPreviewWidget->currentBrush = b;
      b->setProcessor(&processor);
      QAction *action = new QAction(b->getIcon(),b->getName());
      action->setCheckable(true);
      QDockWidget *pluginDock = new QDockWidget(b->getName(),this);
      QWidget *pluginGui = b->loadGUI();

      addDockWidget(Qt::LeftDockWidgetArea,pluginDock);
      pluginDock->setFloating(true);
      pluginDock->setFeatures(QDockWidget::DockWidgetMovable | QDockWidget::DockWidgetFloatable);

      pluginDock->setWidget(pluginGui);

      pluginDock->setVisible(false);
      connect(action,SIGNAL(toggled(bool)),pluginDock,SLOT(setVisible(bool)));

      ui->pluginToolBar->addAction(action);

      plugin_docks_list.append(pluginDock);

    }
  }
}

              This is the first time i make plugins for my apps. I save then in the appdata location, and then load from there.

                  Your plugins path is a bit surprising. On macOS they should be in your app bundle but your are looking for them in your system. Is that really the case ?

                  Did you already check the Plug and Paint example ?

                    @SGaist Yes, i checked it while i was working on the plugin in linux. The thing is that i want users to be able to "install/remove" plugins, and that when they download a new release, that plugins remain. So i tried using the appdata location in the system, and worked both in linux and windows. I don't want to include every single plugin in the bundle, because may be some plugins are only meant for contributors/patreons/etc. Is this possible with mac?
                    Also, a friend of mine tried the app generated without using macdeployqt, and with all dependencies installed, and both the app and the plugin worked fine. The problem is that others users cannot use the app if i don't deploy with macdeployqt.

                      So, in mac i should try using like in plug & paint, and that the user reinstalls the plugins if they download a newer app, right? I could try that.

                        Check your plugin with otool -L you'll see that the libraries it depends on are searched into your application bundle. Hence they will fail to load if you moved them around.

                          @SGaist thanks! otool -l libNormalBrush.dylib gives me this output:
                          https://pastebin.com/9uk06Dqi
                          It doesn't seem to look for them in the application bundle, but on the system, right? So that's what making it crash? it doesn't find the libs?

                            @SGaist Well, i finally managed to get an error, running the executable inside the .app directly from console:

                            That error arrises just when i load the plugin into the application. So i what i understand here is that i must change where the plugin is looking for libs? Can i change that?

                              Yes, you can change that use install_name_tool for that. That's what macdeployqt uses to do its job.

                                @SGaist Thanks! i'll try it tonight. So just so just to be sure, i must change where the plugin libNormalBrush.dylib looks for the libs, and change them to rpath?
                                something like:

                                install_name_tool -change each_one_of_the_libs.dylib @rpath/../lib/each_of_the_libs.dylib libNormalBrush.dylib

                                Right?

                                  Check the Qt plugins to see where they are looking for. You also have to check where your OpenCV libraries are stored in the bundle.

                                    @SGaist Well, i tried with install_name_tool and changed the path correctly (i think) but it stills fails. I think the problem is this line:

                                    ERROR: something wrong with flag 'flagfile' in file '/tmp/gflags-20190105-77846-1pdnfpc/gflags-2.2.2/src/gflags.cc'.  One possibility: file '/tmp/gflags-20190105-77846-1pdnfpc/gflags-2.2.2/src/gflags.cc' is being linked both statically and dynamically into this executable.

                                    but i dont have a clue of what it means. I never had this problem before.

                                        @SGaist Appart from qt libs, i'm using a custom class included in the application. That class uses some opencv libs, so the plugin itself seems to be linking to them. This is what otool says:

                                          @SGaist That output from otool is previous i used install_name_tool to change the path. I looked inside the app and they are located in the same place where QtWidgets.framework and others are located, so i changed the path to @rpath
                                          I dont have the mac right now (its borrowed), but i can send you the updated otool output if needed.
