do you see the same error if you run "glxinfo":http://dri.freedesktop.org/wiki/glxinfo/ or glxgears
@
glxinfo
glxgears
@

under normal user: for both
libGL error: failed to load driver: i965
libGL error: Try again with LIBGL_DEBUG=verbose for more details.

under root:

its seems to run without errors.

I'll try it on monday when i'm on my workstation pc again :)

Sleicreider

bash-4.2$ id
uid=1000(username) gid=100(users) groups=100(users),18(video)

bash-4.2$ ls -l /dev/dri
total 0
crw-rw---- 1 root video 226, 0 Mar 24 08:32 card0
crw-rw---- 1 root video 226, 64 Mar 24 08:32 controlD64

I'm running out of ideas :-)
Maybe this last one

Do you have Mesa libraries installed?
What ldd on your app shows?
@
ldd yourapp | grep libGL
@

And one more.
When you start qtcreator does it show the same error as your app?
If you build any Qt examples and start them do they show the same error?

Sleicreider

bash-4.2$ ldd myapp | grep libGL
libGL.so.1 => /usr/lib64/libGL.so.1 (0x00007f79fab6b000)

somehow i get no error anymore, lol.
(i started the same project)

I also started an OpenGL example. no errors.
:)

idk what happened.

Glad to hear that issue is resolved.

Sleicreider

Could you put [SOLVED] in front of the title of your initial post.
