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

Yup wait a sec

That helps to understand the issue.

I checked and before b01524fff05eef66e8cd24f1c5aacefed4209f03 mesa-git included

usr/lib/pkgconfig/glesv1_cm.pc usr/lib/pkgconfig/glesv2.pc

After that commit those files are no longer present so pkgconfig is not aware the system has gles support. It's unclear to me whether those files should be provided by mesa or glvnd, but one of them has to.

This is not a mutter bug, but a mesa / glvnd miscommunication. Since mesa changed its behaviour I do think a mesa bug needs to be created. Could you create a mesa bug and post the link here and in the (hopefully) existing mutter bug report ?

Haxk20 commented on 2019-03-16 10:40 (UTC)

Dependency glesv2 found: NO (tried pkgconfig and cmake)

meson.build:149:2: ERROR: Dependency "glesv2" not found, tried pkgconfig and cmake

When i revert the patch that disabled gles2 build in mesa-git and i add the one line that deletes libGLESv2.so and gles1 so file then mutter builds without an issue.

Lone_Wolf commented on 2019-03-12 22:25 (UTC) 

       -D gles2=true \

How did you determine GLES2 isn't build ?

Haxk20 commented on 2019-03-12 17:38 (UTC)

Mutter fails to build when GLES2 isnt build. Reported it to mutter devs too. IDK on which side this should be fixed.

Lone_Wolf commented on 2019-03-09 12:15 (UTC)

confirmed and found the cause : https://cgit.freedesktop.org/mesa/mesa/commit/?id=b01524fff05eef66e8cd24f1c5aacefed4209f03

mesa now only builds those librarries when needed (i.e mesa build without glvnd support) so we don't need to remove them anymore.

I'll upload new versions for mesa-git and lib32-mesa-git soon.

PedroHLC commented on 2019-03-09 01:45 (UTC)

@Lone_Wolf thanks for the intel.

Currently builds are failing with:

Running custom install script '/usr/bin/python /home/main-builder/pkgwork/src/mesa/bin/install_megadrivers.py /home/main-builder/pkgwork/src/_build/src/gallium/targets/va/libgallium_drv_video.so lib/dri r600_drv_video.so radeonsi_drv_video.so nouveau_drv_video.so'
rm: cannot remove '/home/main-builder/pkgwork/pkg/mesa-git/usr/lib/libGLESv1_CM.so*': No such file or directory
rm: cannot remove '/home/main-builder/pkgwork/pkg/mesa-git/usr/lib/libGLESv2.so*': No such file or directory
==> ERROR: A failure occurred in package_mesa-git().

That's also similar to lib32. Could you take a look?

Also, you're doing a good work, thank you very much :)

mesa-libgl was an arch linux custom method to allow nvidia proprietary driver and mesa to be installed together. extra/mesa switched to libglvnd method in march 2017[1], my mesa-git switched a few months later.

Packages that still depend on mesa-libgl should switch. Possible options to depend on are libgl / libegl / libgles or opengl-driver .

PedroHLC commented on 2019-02-27 21:38 (UTC)

There are some packages that depend on "mesa-libgl" (the same for lib32-mesa-libgl) what should be made of those? Should mesa-git provides it, or the packages to depends on just "mesa"?
