Hello there

I'm trying to start kmscon with the --hwaccel but I get this assertion : 

   /usr/bin/kmscon --listen --hwaccel --cdev-session --seats=seat1 &

I have 2 nvidia cards using the nouveau driver. everything works fine without the hwaccel. here's the debug output :

That's a mesa bug. kmscon doesn't use C++ or llvm directly ;) It's known and it is fixed in mesa-master. I don't know which versions are affected, sorry, but the next mesa release should include a fix.

vkravets commented 11 years ago

Great news! Thus I will wait the release of mesa to moving fully to kmskon...

Thanks a lot!

Ah ok, thx. I will try to compile a git version then

Thank you :+1:

EDIT: The bug has been corrected here.

The problem was caused by the llvm libs being static. Even with recent install of Mesa (with archlinux anyway) the package is still compiled with the static version of the lib. But I have rebuild the package with : 

   --with-llvm-shared-libs

Using --enable-opencl was asking for too much dependencies in the AUR packages. But now everything is working just fine (well kinda) with --hwaccel

Now that this trouble is out of the way, I can continue with the config of my setup :+1:
