I am using another package now and am looking for a new maintainer.

Lone_Wolf commented on 2020-04-23 12:26

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 me 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

  • 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.

AUR helpers like yay and pamac can't deal with such a dynamic choice. People who use those will have to accept the default of building mesa-git against stock repo packages.

  • issues
Simple issues can be dealth with through aur comments, but sometimes discussion is needed.
Use https://bbs.archlinux.org/viewtopic.php?id=212819 for that.
  • 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 , restart X .

run glxinfo to verify basic OpenGL functionality

build lib32-mesa-git

run glxinfo32 to verify basic OpenGL functionality for multilib programs

0001-clover-llvm13-use-FixedVectorType.patch is missing a semicolon in the #else clause.

Thanks for reporting the issue. It's been fixed now.

Nice try :)

TkG commented on 2021-02-17 14:06

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

Confirmed, needed for all llvm trunk builds.

A temporary workaround is to disable building gallium-opencl .

rjahanbakhshi, please look into adding this commit.

It can be downloaded as patchfile from https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/8543.patch

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