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

Thanks, Faalagorn.

Working on adjusting to that.

AUR Helpers are NOT supported

I built and test with makepkg. Building with Devtools and Clean Chroot Manager should work fine also (I test them occasionally).

This package and lib32-mesa-git use a custom method to dynamically determine which llvm version is to be used. Several AUR helpers (atleast pamac and yay) have problems with that method.

Incase you try to build mesa-git with one of those AUR helpers

& ARE NOT USING THE DEFAULT SETTING OF MESA_WHICH_LLVM ,

run makepkg --printsrcinfo > .SRCINFO after downloading and BEFORE building.

That should help pamac and yay to handle my custom method.

Faalagorn commented on 2019-06-02 23:36 (UTC)

lordheavy finally switched from -svn to -git in the "mesa-git" unofficial repo, so the PKGBUILDs might require an update to reflect that :)

Lone_Wolf commented on 2019-05-30 18:39 (UTC)

That sounds like those aur helpers use .SRCINFO to determine needed dependencies instead of the PKGBUILD itself.

The way this PKGBUILD works is that the real makedeps & deps are determined at buildtime.

It seems there's an implicit assumption in SRCINFO : the information in it is static and doesn't change.

For mesa-git and lib32-mesa-git that assumption fails.

I'm going to create a thread in AUR Issues, Discussion & PKGBUILD Requests forum board to discuss this.

yurikoles commented on 2019-05-30 16:49 (UTC)

but AUR helpers, e.g. yay want to install llvm-minimal-git before mesa-git

Lone_Wolf commented on 2019-05-30 13:17 (UTC)

Changed how NINJAFLAGS is used, package should now build ok if it's not defined.

That's correct yurikoles.

makepkg --printsrcinfo does process the PKGBUILD, sees MESA_WHICH_LLVM is set to 1 on my system, writes llvm-minimal-git as makedep and llvm-libs-minimal-git as dep in .SRCINFO .

When the user runs makepkg, it will use their systems value of MESA_WHICH_LLVM . If they haven't set it, makepkg will use the default of 4 and use extra llvm / llvm-libs .

The end result is : action is needed to build mesa-git against any llvm trunk version.

yurikoles commented on 2019-05-30 11:16 (UTC)

@Lone_Wolf, there is llvm-minimal-git in makedepends in .SRCINFO.

artivision commented on 2019-05-29 11:26 (UTC)

Fail with /var/tmp/pamac-build-jojo/llvm-minimal-git/src/_build/ empty error.

Lone_Wolf commented on 2019-05-27 12:43 (UTC)

After thinking about NINJAFLAGS I now feel it's the user responsibility to ensure its value will work. The PKGBUILD no longer checks for validity of $NINJAFLAGS.

If unsure, don't use it.

Lone_Wolf commented on 2019-05-26 14:07 (UTC)

I'd prefer issues with diff files attached over pull requests or merge requests , but neither is currently possible within AUR.

CI sounds nice especially with 4 choices for dependencies, but those docker images would have to be updated atleast several times a week. Maybe if llvm-git & llvm-minimal-git were also included the extra work is worth it.

That suggests this shouldn't be a one-person initiative. How flexible are gitlab / github for setting up and managing a small collaboration ?

Gitlab seems to be a bit friendlier towards open source then github and gitlab source code is available. If all other things are equal, I'd prefer gitlab I think.

One question we should answer before doing anything is : What license will files be published under ? In my opinion PKGBUILD and related files are not original works, so don't have any copyright attached. No idea how to express that in a icense though.
