Description LABBE Corentin 2014-04-02 12:35:22 UTC

media-libs/raspberrypi-userland provides opengl implementation for the raspberry pi.
So virtual/opengl should depend on it

Reproducible: Always

Steps to Reproduce:
1. emerge anything with that depends on virual/opengl on a raspberrypi
2.
3.
Actual Results:  
emerge want media-libs/mesa to be installed even if media-libs/raspberrypi-userland is merged

Expected Results:  
emerge wont emerge media-libs/mesa

I'm not so sure about this, at least the current raspberrypi-userland in tree provides only libEGL and libGLES*. So anything which requires libGL would fail to build.

Comment 3 LABBE Corentin 2014-04-02 15:02:21 UTC

On raspberry pi, the only way to have some opengl is raspberrypi-userland.
So any source that fail to compile, will fail anyway.
But by adding raspberrypi-userland to virtual/opengl, this will allow some application to compile (xbmc is an example)

No. OpenGL is provided only by mesa. raspberrypi-userland provides libraries for accelerated OpenGL ES. It does not provide libGL.so which is absolutely required by OpenGL (non-ES) applications.

Do not confuse OpenGL with 3D acceleration.

Comment 5 LABBE Corentin 2014-04-02 19:17:26 UTC

I agree that raspberrypi-userland do not provide strictly the opengl library.
But I viewed virtual/opengl as a way to provide a depends on all opengl related stuff, like eselect-opengl is a way to switch between all opengl related library.

If you do not follow my interpretation, you can close this bug.
If so perhaps creating a virtual/gles is a better idea ?

Yes.
