Hi All,
I've been building just the mesa source package locally now against stretch-backports since mesa 17.3.7 and the build process just works.
Since all the build dependencies are now in stretch-backports, what else needs to be done to get mesa into stretch-backports?
I note that Timo (?) created a branch in salsa which contains Jérémy's backport that was submitted to mentors, so that would probably want to be updated to 17.3.9 (which should hopefully hit testing in ~2 days).
One other thing:
The only thing that appears to be missing in stretch-backports is libclc-dev (>= 0.2.0+git20180312-1~). Currently stretch-backports has 0.2.0+git20171106-1~bpo9+1. Everything else seems to be there.
