Application with plugin crashes after calling macdeployqt.
-
Check your plugin with
otool -Lyou'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 Well, i finally managed to get an error, running the executable inside the .app directly from console:
"/Users/mac/Library/Application Support/laigter" objc[95815]: Class CaptureDelegate is implemented in both /Users/mac/laigter-1.8/laigter.app/Contents/Frameworks/libopencv_videoio.4.1.dylib (0x1046d1ae0) and /usr/local/opt/opencv/lib/libopencv_videoio.4.1.dylib (0x12745aae0).

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.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_toolfor that. That's what macdeployqt uses to do its job. -

something like:install_name_tool -change each_one_of_the_libs.dylib @rpath/../lib/each_of_the_libs.dylib libNormalBrush.dylibRight?
-
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_tooland 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.
-
What libraries are you using for that plugin ?
-
@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. -
Yes, that would be nice.
Just for the sake of testing (and to ensure I am not missing anything), Does it also crash if you keep the plugin within the bundle with the other plugins ?
