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

@rjahanbakhshi
I was trying to solve the issue of xorg-server-git looking for a package that provides mesa-libgl.
Right now, if mesa-git is installed, pacman either tries to install lib32-mesa or, if lib32-mesa-git is also present, prompts to replace mesa-git with the non -git variant.
I saw mesa-libgl in the non -git variant's provides list, and thought it was an issue with this package, but have since read Lone_Wolf's and yurikoles' comments, and am waiting for further developments :)

Then it seems you're in a good position to verify whether mesa-libgl is still needed for xorg-server-git and remove it as a depend if it isn't .

xorg-server-git co-maintainer here, actually our deps are set in accordance to official xorg-server package, which depends on both mesa and mesa-libgl.

rjahanbakhshi commented on 2021-10-22 11:53 (UTC)

@Lone_Wolf,

Thanks for the explanation. Makes sense. I will revert the changes.

@feral_hedgehog,

I'd like to know what problem you're trying to solve by adding mesa-libgl to the provides list.

Lone_Wolf commented on 2021-10-22 10:13 (UTC)

mesa-libgl stopped being a real package around 2018 and everything it did provide has since its removal been provided by mesa .

All packages that still depend on mesa-libgl should change to mesa.

Reza, please undo the change.

feral_hedgehog, xorg-server-git already depends on mesa. Please ask xorg-server-git maintainer to remove mesa-libgl from dependencies.

rjahanbakhshi commented on 2021-10-22 09:26 (UTC)

@feral_hedgehog

Since mesa has mesa-libgl in its provides list and no other packages have it as far as I can see, I guess there's no harm adding it to this package as well. I've updated this PKGBUILD and added mesa-libgl to the provides and conflicts lists.

feral_hedgehog commented on 2021-10-22 01:24 (UTC)

Hello!
Could you please add 'mesa-libgl' to the provides list? It's present in the (non -git) mesa package but missing here.
I've added it manually, and it appears that packages that require it (specifically xorg-server-git) work fine.
Thank you for this package!

Lone_Wolf commented on 2021-10-20 08:59 (UTC)

libffi has been updated and this requires a rebuild of all llvm trunk variants.

After that rebuild has finished you will need to rebuild this pacakge also .

NOTE :

I don't know if repo llvm will also need a rebuild. https://archlinux.org/packages/community/any/rebuild-detector/ can help to determine that.

rjahanbakhshi commented on 2021-10-13 22:50 (UTC)

Patch removed since it's already applied upstream.

Lone_Wolf commented on 2021-10-13 20:28 (UTC)

confirmed, my MR for it has been accepted into main. see https://gitlab.freedesktop.org/mesa/mesa/-/commit/ebfbb42e0e534b0b5c06c79b723a745a2224451d

For now just edit the PKGBUILD and comment out the 1 line in prepare() that starts with patch .
