for some reason eglCreateWindowSurface() fails now when running on OpenPandora when I build BetaBlockQuest, or anything using EGL.
on the OpenPandora it doesn't matter if I cross-build, if I build natively on OP in my debian chroot, or natively on OP using cdevtools1000,
I get the same result in all cases: "eglCreateWindowSurface() failed"
I've made a tiny EGL initialization test that creates a window then cycle the clear color to try to narrow down the issue.
on OP it just returns an error: EGL_BAD_NATIVE_WINDOW
on the PandaBoard it runs fine.
and from the EGL examples and documentation, it *should* work... and it does, just not on OP
so I can't update BetaBlockQuest
