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

@miguel-rangel,

I don't see the issue in a clean build environment.

miguel-rangel commented on 2022-06-05 06:33 (UTC) (edited on 2022-06-05 06:42 (UTC) by miguel-rangel)

I was getting the following error:

Running custom install script '/bin/python '.../mesa-git/src/mesa/bin/install_megadrivers.py rm: cannot remove '../mesa-git/pkg/mesa-git/usr/bin/mesa-overlay-control.py': No such file or directory ==> ERROR: A failure occurred in package(). Aborting... Its getting stuck because of this line in 163 of the PKGBUILD. This script is not in the directory. rm "${pkgdir}/usr/bin/mesa-overlay-control.py" when removed/commented out, the package should build

Hi @AkechiShiro,

Thanks for the report. Personally, I haven't seen this problem. But I removed lto flag for now until the bug is reported as fixed.

AkechiShiro commented on 2022-05-21 08:31 (UTC)

To this day, there are issue with the current version : 22.2.0_devel.154303.e8eb6d13a5d.d41d8cd98f00b204e9800998ecf8427e-1 a bug is affecting all chromiums/Electron apps, with graphical glitches showing up on an AMD Ryzen 7 3700U with an iGPU Radeon Vega RX 10.

It could be worked around by following the instruction given in this issue : https://gitlab.freedesktop.org/mesa/mesa/-/issues/6486

Namely, to compile mesa with this flag -D -n_lto=true removed.

@ilikerackmounts,

Thanks for the report. The patch is removed now.

ilikerackmounts commented on 2022-05-07 17:03 (UTC)

It appears the clover-compat patch no longer applies. Please remove that from the pkgbuild

Thank you @Lone_Wolf,

The following patches are applied.

Some changes are needed for this package.

https://github.com/llvm/llvm-project/commit/483efc9ad04dccd9f2163c84c2b6198ebb7049a6 leads to a build failure when building mesa trunk against llvm trunk versions.

see https://gitlab.freedesktop.org/mesa/mesa/-/issues/6359 for a workaround patcch.

https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/15258?commit_id=7ab05e3c3fe34ea7f8d7345b9229c163e42c3600 disabled several codes by default making hw acceleration almost useless.

use the new option video-codecs to re-enable them (see meson_options.txt ).
