Qt can't find platform plugins when loaded by JNI

wish of those help One solution would be to place your DLL/shared Qt C++ library under an accessible directory and add that directory name to Qt's library path:
code :
QApplication::addLibraryPath(<full path of your directory name>);
QApplication::addLibraryPath(QLatin1String("/tmp/qt5/plugins"));

around this issue So far, the best answer I've found is to use Google's "Pepper"

I hope this helps . I am aware of two approaches to installing Jenkins plugins over the remote API, given a textfile with a newline separated list of plugin shortNames, e.g. , You can GET this endpoint:
code :
http://my-jenkins:8080/updateCenter/api/json?tree=jobs[*]
{
   "_class":"hudson.model.UpdateCenter",
   "jobs":[
  {
     "_class":"hudson.model.UpdateCenter$ConnectionCheckJob",
     "errorMessage":null,
     "id":3,
     "type":"ConnectionCheckJob"
  },
  {
     "_class":"hudson.model.UpdateCenter$InstallationJob",
     "errorMessage":null,
     "id":1,
     "type":"InstallationJob",
     "name":"Xamarin Studio Tool Runner Plugin",
     "status":{
        "_class":"hudson.model.UpdateCenter$DownloadJob$SuccessButRequiresRestart"
     },
     "plugin":{

     }
  },
  {
     "_class":"hudson.model.UpdateCenter$InstallationJob",
     "errorMessage":null,
     "id":2,
     "type":"InstallationJob",
     "name":"PAM Authentication plugin",
     "status":{
        "_class":"hudson.model.UpdateCenter$DownloadJob$Pending"
     },
     "plugin":{

     }
  }
]}

around this issue There is a option you can pass to when you invoke it to create the executable for the main application: -rdynamic
code :
$ gcc -rdynamic -o app app.c -ldl

I wish did fix the issue. Re macdeployqt fails: it seems like, for the argument to macdeployqt you are passing the path to the executable instead of the path to the bundle. I.e. just pass .../MyProgram.app instead of .../MyProgram.app/Contents/MacOS/MyProgram.
(But I am also unable to get it find libqcocoa, in a sandboxed app. I may resort to linking that statically into my app.)

Does that help If the linuxfb plugin doesn't work, then possibly you didn't correctly configure the framebuffer device on your system. Maybe a directf layer is already running, so you may want to try the directfb plugin instead.
If you wish to avoid having to specify the platform option when you run the executable, you can pass the default one to configure when you build Qt.
