Re: [Buildroot] [PATCH v1 1/2] package/mesa3d: add config option for DRI3 support

[Michael Taubert <info@arachnodroid.de>]

Hi!

Got back to this topic this morning.

According to this line for V3D/VC4:

select BR2_PACKAGE_MESA3D_DRI3 if BR2_PACKAGE_XORG7

Mesa3D will be built with DRI3 support only if xorg is going to be used 
too. Though I'm actually using xorg, and can confirm that is compiling 
properly with X, I may have a switch to wayland anytime soon. Is xorg 
really required?

I must admit that the build did not complete, due to an error with 
libnss. So it's just what I got from the build logs.

Regards,
Michael
