removed obsolete options, build now works again.

building opencl clover is disabled for now, see https://gitlab.freedesktop.org/mesa/mesa/-/issues/11863

Those that need opencl should use rusticl instead. Note that rusticl at runtime is disabled by default, see https://docs.mesa3d.org/envvars.html#rusticl-environment-variables for info about enabling it.

Mesa and llvm are closely tied together. Everytime the llvm mesa is built against changes/updates , mesa needs to be rebuilt.

I expect anyone building mesa-git against one of the llvm trunk variants to be able to do that themselves, but atleast some of the people that built against repo llvm don't understand how to deal with such a rebuild.

The rest of this post is meant for those people.

  • Verify if latest PKGBUILD requirements match llvm repo versions.
  • If they don't , post to alert the maintainer of this.
  • DELAY the update of llvm/clang suite and their lib32- counterparts
  • Once the PKGBUILD does match, download it.

Option A - best one

  • run pacman -Syu to ensure your system is in sync with your mirrror server
  • build mesa-git in a clean chroot

see https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_clean_chroot for the official way or https://aur.archlinux.org/packages/clean-chroot-manager for an alternative method.

  • install the newly built mesa-git
  • run pacman -Syu
  • ready

Option B - 2nd best

  • revert to repo mesa
  • pacman -Syu
  • build mesa-git
  • switch from mesa to mesa-git
  • ready

  • choosing which llvm variant to build against

WARNING : aur helpers don't support this method at all. They check .SRCINFO and that doesn't include this variable so it will use the default which is hardcoded to build against repo llvm.

Why would I want to use llvm development versions ?

For full functionality and latest features mesa trunk master needs to be build against llvm trunk master.
If you build against stable llvm things MAY work, but you're likely to lack some features and face stability issues.

Mesa-git uses a custom environment variable MESA_WHICH_LLVM for flexibility.
It has 4 values.
1 : aur llvm-minimal-git
2 : aur llvm-git
3: llvm-git from LordHeavy' unofficial repo
4: llvm from extra repo

I use value 1 95% of the time and set this in ~/.bash_rc .
If MESA_WHICH_LLVM is unset or empty, the default value of 4 (extra llvm) is used.

  • main difference with stable repo package
[extra]mesa is a split package, but aur mesa-git isn't.
Basically with aur mesa-git you get everything in one package, while [extra]/mesa allows you to leave out some parts if you don't want/need them.
Having a single package reduces maintenance and makes switching from stable to mesa-git rather easy, though reverting back to stable can be tricky.
  • meson settings
Those who compare PKGBUILDs will notice I don't use arch-meson, but meson setup.
I disagree with some of the settings made by arch-meson (especially the buildtype and enabling LTO by default) and feel using meson setup is cleaner.
  • how to update

run pacman Syu update non-repo packages for llvm if you use them

build mesa-git, log out , update mesa-git and restart X .

run glxinfo -B to verify basic OpenGL functionality

build lib32-mesa-git

run glxinfo32 -B to verify basic OpenGL functionality for multilib programs

Can mesa-libgl added to the things the package provides? wine-gaming-nine needs it to build. (you can comment the dependency from wine gamings package build and it compiles just fine but still would be nicer not to do this workaround). TIA

@zfkerr :

So mesa-git plus wayland-git are not enough to run a wayland sesssion in gnome. Have you tried running a wayland session with another compositor like weston, plasma, sway to verify if this is a gnome-specific issue ?

@mirh

extra/mesa is a split package, my mesa-git isn't . For mesa-git to be able to replace extra/mesa several things are needed :

  • mesa-git has to provide/conflict all sub-packages
  • mesa-git has to provide/conflict/replace everything all those sub-pacakges provide/conflict/replaces

This results in a huge list. I looked closely at that list and realised it listed many remnants of previous mesa versions, specifically all *-dri packages and mesa-libgl no longer exist in repos and i removed them.

mirh commented on 2018-04-29 22:05 (UTC)

If this package replaces "official" mesa, why isn't it providing the same provides/conflicts/replaces directives?

@Lone_Wolf, I use AUR wayland-git, but GNOME Wayland still does not work anyway if mesa-git does not have this building option

--with-platforms=x11,drm,wayland \

@zfkerr, for wayland see the (updated) pinned comment.

The surfaceless platform was originally designed for chrome OS, but is said to have other usecases also. It was added to [extra] mesa 18.0.0, and this package tries to stay close to [extra] mesa.

zfkerr commented on 2018-04-26 08:44 (UTC)

@Lone_Wolf, you need a "wayland" building option so that Wayland sessions can work, because without this option it do not work.

 --with-platforms=x11,drm,wayland \

And what does the "surfaceless" option mean and why is it needed?

Lone_Wolf commented on 2018-04-24 14:19 (UTC)

  • @yans : that file is now provided by wayland-git. verify you have wayland-git (still) installed, then try firefox again.

  • If it still fails, which version is your wayland-git ? What output does starting firefox from CLI give?

Lone_Wolf commented on 2018-04-24 14:16 (UTC) (edited on 2018-04-24 14:19 (UTC) by Lone_Wolf) 

I've filed a bug report for the build failure with latest llvm-svn, see https://bugs.freedesktop.org/show_bug.cgi?id=106209 .

If you prefer not to wait until this is solved and don't need opencl support :
remove the 2 lines mentioned in the bug report.
