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

Hello, I maintain mesa-git package and it provides intel-dri-git too. I cannot upload a real split package because of this. Would you care to merge this package into mesa-git? Thanks.

Lone_Wolf commented on 2014-03-27 11:41 (UTC)

- changed from libclc-git to libclc as dependency - moved libomxil-bellagio to optdepends - switched from classic osmesa to gallium osmesa - enabled gallium tests

anadon commented on 2014-03-26 19:21 (UTC)

Everything works on my system without a hitch.

Lone_Wolf commented on 2014-03-25 11:43 (UTC)

that is correct, jpapadopoulos. I checked the mesa-git/libclc-git packagebuild and it does provide libclc . http://pkgbuild.com/~lcarlier/mesa-git/sources/libclc-git/PKGBUILD I'll change the dependency from libclc-git to libclc in next version. Then all that's needed to use either libclc-svn or libclc-git is for libclc-svn maintainer to add provides=('libclc') to the liblcl-svn PKGBUILD.

jpapadopoulos commented on 2014-03-25 11:28 (UTC)

There is an issue with building this without the mesa-git repo as a libclc-git PKGBUILD does not exist in AUR. There is only this package using svn(Apparently they use both) https://aur.archlinux.org/packages/libclc-svn/

moved opencl related dependencies from depends to optdepends so they can be removed after building

Lone_Wolf commented on 2014-03-10 16:14 (UTC)

maybe you were thinking of this : OpenCL implementation from AMD is known as AMD APP SDK, formerly also known as AMD Stream SDK or ATi Stream. arch opencl wiki page has more info, but afaict AMD APP SDK allows the CPU to be used for opencl, NOT the graphics card.

lockheed commented on 2014-03-09 13:24 (UTC)

Thanks. But wasn't there something like "stream"? I read somewhere that thanks to it computations could be run on R600 cards.
