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

the /src/intel is probably not what caused the build failure but just the job that ran the longest after the error occurred.

Post the build log somewhere public, see https://wiki.archlinux.org/title/List_of_applications#Without_a_dedicated_client for a few options.

Building in a clean chroot after having built llvm-minimal-git. Build fails:

[1026/2687] Compiling C object src/intel/perf/libintel_perf.a.p/meson-generated_.._intel_perf_metrics.c.o ninja: build stopped: subcommand failed. ==> ERROR: A failure occurred in build(). Aborting...

Will fail at lines 1020~1030 when at src/intel Not sure if if should be reported here or at mesa, please delete the comment if it is not appropriate here.

EDIT seems to be compiler issue. llvm-minimal-git-18.0.0_r475270.a93e76dd8778-1 fails but llvm-minimal-git-18.0.0_r474414.0528dbfe5c88-1 (compiled last week?) seems to be compiling.

The clang and llvm version on Arch Linux has been updated

I am experiencing segfaults with e.g. vkcube-wayland, and really any other vulkan + wayland client. Its segfaulting when trying to create the swapchain.

Anyone else experiencing this, or any ideas?

Yes it has been, but a lot of the code has since been updated by other commits.

Hi, I have a question. Does it contain the following commit?

I just ran into the missing glslangValidator build issue as well. If anyone else is building in a chroot and wants a quick fix to get the build moving again I've made an empty package that depends on glslang and creates the glslangValidator symlink using an install script.

https://gist.github.com/foundObjects/5fee314e27d7897212443da8d7db8b5b

I built the above into my aurutils repo then added a glslang-validator-symlink dependency to mesa-git's PKGBUILD and my clean chroot mesa-git builds are moving along nicely again.

https://github.com/KhronosGroup/glslang/pull/3283 https://bugs.archlinux.org/task/79212

Options :

  • Downgrade to glslang 12.2.0
  • create a symlink as described below
  • wait for arch devs to patch this
  • wait for upstream to fix this
