Hello, To put it simply, upstream (OpenMW) has no plans to support GLESv2 at this time. Since OSG-3.4 for armhf is compiled only for GLESv2, this complicates things drastically and at this point I'm in over my head.
If we try to switch out <GL/gl.h> with <GLES2/gl2.h>, we clear up the above error but then it fails later because GLESv2 doesn't ship with support for other things defined in <GL/gl.h> that are required throughout the OpenMW code base. At this point I recommend disabling OpenMW for armhf until either OpenMW supports GLESv2 (likely not to happen soon) or OSG-3.4 (find a better solution[1]) supports plain old OpenGL again and not exclusively GLESv2 on armhf. I don't understand why we can't just use plain old OpenGL on armhf and it seems like OSG-3.4 armhf support is a bit of a hack. I had OpenMW running on Raspberry Pi 2 for example just last year. Any thoughts, suggestions or other workarounds?
