I get some segfaults upon shutting down my OpenGL test application and in order to check wether the error is on my fault I noticed the OpenGLAppExample is outdated. It seems to be still using the old OpenGL Component/render API. Also, it does not even build if I generate the Linux Makefiles via Introjucer. Juce library headers aren't referenced/wrapped properly, it says e.g.
#elif defined (JUCER_LINUX_MAKE_6D53C8B4)
which should read
Same for all the other library components. I wonder how the paths can end up wrong since the headers are regenerated by the Introjucer...
Anyways there is the "OpenGL Application" project preset by now (and testing that shows the error is on my part, as expected). So I think the OpenGLAppExample should be removed from the project.
Now let's see what I'm doing wong...
