an init script already takes care of loading the modules, so the

and my program when execute sudo make run output this
[ error ] ofAppGLFWWindow: 65542: X11: Failed to open X display

X11... First line of:
http://elinux.org/BeagleBoardDebian#SGX_BeagleBone.2FBeagleBone_Black
Note, these are FBDEV only, no xorg/x11/etc...
We've never had x11 support for the am335x, and we NEVER will..
Rebuild qt5 with eglfs, there's a lots of guilds in this forum, that
works for opengl es...
How does one know if qt was build with eglfs. I thought that mine was
but I cannot seem to get xcb working at all. It is just not available as
an option when running code.
I dont have x11 support installed. Headless only.
