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

Strunkenbold, I updated both mesa-git & lib32-mesa-git a few hours ago.

Make sure you have wayland 1.15 and lib32-wayland 1.15 installed, even if that means you have to remove old lib32-mesa-git (or lib32-mesa) with -Rdd . Once that's done, try the latest versions.

Strunkenbold commented on 2018-05-26 12:20 (UTC)

Without setting wayland, it fails to compile: No rule to make target „/unstable/linux-dmabuf/linux-dmabuf-unstable-v1.xml“

and with wayland set it complains: Fehler: Konnte den Vorgang nicht durchführen (In Konflikt stehende Dateien) lib32-mesa-git: /usr/lib32/libwayland-egl.so existiert im Dateisystem lib32-mesa-git: /usr/lib32/libwayland-egl.so.1 existiert im Dateisystem lib32-mesa-git: /usr/lib32/libwayland-egl.so.1.0.0 existiert im Dateisystem lib32-mesa-git: /usr/lib32/pkgconfig/wayland-egl.pc existiert im Dateisystem

So it looks like mesa still wants to install those files. Is this an arch problem or a mesa bug? Or is something wrong with my installation?

That's at the same place in the code, but a different error. It doesn't happen with llvm-svn 7.0.0svn_r333179-1 . Which llvm-svn version do you have, craftyguy ?

Edit : also no problems with llvm-svn-7.0.0svn_r333339-1 .

craftyguy commented on 2018-05-26 00:19 (UTC)

Still failing to compile: https://hastebin.com/wixuwomuna.rb

levisraju commented on 2018-05-24 04:28 (UTC)

The patch has been added to package and everything works fine now.

A new build failure, again opencl related. https://bugs.freedesktop.org/show_bug.cgi?id=106619

patch applied,build works again

C0rn3j commented on 2018-05-20 20:40 (UTC)

The OpenCL issue has been resolved, could you update the pinned message?

there's also this line in the PKGBUILD "# broken, see https://bugs.freedesktop.org/show_bug.cgi?id=106209"

yans commented on 2018-05-18 06:39 (UTC)

@Lone_Wolf wayland 1.15 official realesed. I will try to built fresh new mesa-git & company now, Hope it will works.

Lone_Wolf commented on 2018-05-13 11:20 (UTC)

opencl patch applied after checking the patchwork thread about it (lined in the upstream bug report) .

@Strunkenbold : mesa-libgl was removed from repos when we switched to libglvnd . wine-gaming-nine (and actually all repo wine packages) should switch to the new situation and depend on libgl or opengl-driver . libgl , provided by libglvnd, is probably best choice.
