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

Nice try :)

I'm available to maintain the package @Lone_Wolf

llvm trunk builds give another build failure wrt opencl , see https://gitlab.freedesktop.org/mesa/mesa/-/issues/4200

Lone_Wolf commented on 2021-01-20 23:25 (UTC) (edited on 2021-01-20 23:25 (UTC) by Lone_Wolf)

Confirmed, needed for all llvm trunk builds.

A temporary workaround is to disable building gallium-opencl .

rjahanbakhshi, please look into adding this commit.

Building against llvm-git requires: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/8543

Ignoring updates leads to partial updates which cause problems. It should only be done temporarily for a short period.

Some people had the same issue I had when trying to update their system 

error: failed to prepare transaction (could not satisfy dependencies)
:: installing lib32-llvm-libs (11.0.1-1) breaks dependency 'lib32-llvm-libs=11.0.0' required by lib32-mesa-git
:: installing llvm-libs (11.0.1-1) breaks dependency 'llvm-libs=11.0.0' required by mesa-git

To update your system anyway, you need to ignore those two package with the --ignore option :

sudo pacman -Syu --ignore=lib32-llvm-libs,llvm-libs

This ignore them temporary. You need to modify your .conf file to make it permanent.

@zangoku

You can work around this issue by installing official extra/mesa which consequently removes mesa-git, then update using pacman, and reinstall mesa-git after. 

sudo pacman -S mesa
sudo pacman -Syu
makepkg -sri

You could also use the clean chroot method. Please see the pinned comment above for the details. Here's the brief:

mkdir ~/chroot
CHROOT=$HOME/chroot
mkarchroot $CHROOT/root base-devel
arch-nspawn $CHROOT/root pacman -Syu
cd YOUR_MESA_GIT_DIR
makechrootpkg -c -r $CHROOT

Find the newly created mesa-git package by 

ls -t *.zst | head -n1

Install the created package and update the system 

sudo pacman -U mesa-git-xxx.pkg.tar.zst
sudo pacman -Syu

You can remove the created chroot directory to save the space if you want 

sudo rm -rf $CHROOT
