    Phoronix: Mesa Eyeing The Removal Of Autotools Build Support In Favor Of Meson

    For those currently relying upon Autotools for building Mesa3D, the days are numbered and soon will likely need to shift over to their modern Meson build system support...

    Good, that should make things a bit easier. Debian will have to pick it up, it's still using autotools for Mesa build.

      Hope this doesn't happen with X.Org any time soon. The meson build is still broken on Arch Linux, and it seems nobody can replicate my issues (horrible performance, awful stuttering when tearfree is enabled on AMDGPU); I get by on building it with autotools for the time being.

        ....and there goes uber portable Mesa3D.

          If you want to try, you can try building the mesa PKGBUILD with setting `b_ndebug` set to to false https://git.archlinux.org/svntogit/p...kages/mesa#n40, that can cause quiet a bit of stuttering (I've experienced it myself).

            How have the build-times been for people who build mesa themselves? It seems there are some benefits, between 10-20% in the case of mesa on my machine:

            (18.2.0 and later are built using meson)

              How many cores do you use?

                Citing verbatim from https://mesa3d.org/meson.html


                The meson build is tested on on Linux, macOS, Cygwin and Haiku, it should work on FreeBSD, DragonflyBSD, NetBSD, and OpenBSD.


                Afaik FreeBSD has Meson in their repo, if it does not work it's their own issue. Afaik other BSDs don't focus on GUIs so even if it does not work it's no big loss.

                Seriously man, it's tested on Haiku.

                  Fill a bug report to Mesa maybe ?
