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

Could you please add Nouveau NVK to the PKGBUILD?

ZephyrCheez commented on 2024-03-08 22:53 (UTC)

Since NVK has been declared no longer experimental, it should be added to the PKGBUILD

yurikoles commented on 2024-03-08 09:07 (UTC)

Why don't you set gallium-drivers, vulkan-drivers, tools and video-codecs to all?

Do setting b_lto=false to meson enough to disable lto?

with the default makepkg.conf now enable lto by default.(pacman 6.0.2-9) 

OPTIONS=(strip docs !libtool !staticlibs emptydirs zipman purge debug lto)

It look like the package still build with lto enable.
meson still passed -flto=auto to compiler and lto1 is still ran.

Changing CFLAGS, CXXFLAGS, and RUSTFLAGS before building seem to fix it.

@Beiruty, those have the same cause as the other recent build failures : changes in intel drivers.

The build issues caused by changes in intel drivers are now solved for MESA_WHICH_LLVM 1, 3 and 4 (llvm-minimal-git , llvm from lordheavy unofficial repo and offical repo llvm )

MESA_WHICH_LLVM 2 (aur llvm-git) build is still broken, but I MAY have a solution for that without having to create new packages.

The good news is that once all 4 variants built again, only minor changes should be needed to add opencl clover & opencl rusticl support.

(A lot of the work required to built the intel drivers is also useful for clover & rusticl)

It's definite now it seems, in merge request !27645, the option to disable intel-clc has been removed, having a hard dependency for libclc in anv, crocus, iris.. https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27645/diffs?commit_id=dbdf546fd6562b56df6da4d79c4057e1e30e0755

If I build crocus on x86_64 without OpenCL and libclc I get: mesa/src/intel/shaders/meson.build:45:6: ERROR: Unknown variable "prog_intel_clc".

Which is sad, having Crocus as a backup is important to me, but I don't need OpenCL right now
