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
Created attachment 374092 [details, diff] Add media-libs/raspberrypi-userland as an opengl implementation provider
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.
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.
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 ?
