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

Package depends on libcl, but this cant be found anywhere now.

aig commented on 2016-12-01 23:04 (UTC)

It seems that vulkan-icd-loader now depends on vulkan-driver, which gave me some conflicts with the regular updates of my arch system. If I remember correctly pacman wanted to replace mesa-vulkan-intel-git and mesa-vulkan-radeon-git with the regular packages from the extra repo to statisfy that dependency. Maybe you could take a look at my patch at http://pastebin.com/A1XSsJb2 With this change it seems to be working fine for me now.

FYI: PKGBUILD patch applied. Many thanks to Lone_Wolf and Kerberizer for their hard work :)

kerberizer commented on 2016-11-10 13:15 (UTC)

[IMPORTANT] Mesa again builds correctly with the latest {,lib32-}llvm-svn, so it's safe to update your LLVM packages. DON'T FORGET TO REBUILD MESA! NB: You might need this tiny patch to mesa-git's PKGBUILD, which I'm sure @Lone_Wolf will apply shortly. diff --git a/PKGBUILD b/PKGBUILD index 0a8836e..96d5c8d 100644 --- a/PKGBUILD +++ b/PKGBUILD @@ -168,7 +168,7 @@ package_mesa-vulkan-radeon-git() { conflicts=('vulkan-radeon') install -m755 -d ${pkgdir}/usr/share/vulkan/icd.d - mv -v ${srcdir}/fakeinstall/usr/share/vulkan/icd.d/radeon_icd.json ${pkgdir}/usr/share/vulkan/icd.d/ + mv -v ${srcdir}/fakeinstall/usr/share/vulkan/icd.d/radeon_icd.*.json ${pkgdir}/usr/share/vulkan/icd.d/ install -m755 -d ${pkgdir}/usr/lib mv -v ${srcdir}/fakeinstall/usr/lib/libvulkan_radeon.so ${pkgdir}/usr/lib/

@kerberizer thanks for the updates

[NOTICE] Update for the LLVM r286062 issue with Mesa is now in code review: https://patchwork.freedesktop.org/series/14932/ Edit: Updated the link.

kerberizer commented on 2016-11-07 14:47 (UTC)

[HEADS UP] LLVM r286062 breaks Mesa If you use llvm-svn with Mesa, particularly for the AMD open source driver, DO NOT upgrade LLVM to version >=r286062. Upgrading will not only break the existing driver, but will also prevent you from building Mesa altogether (in both cases there will be error messages related to missing LLVMAddFunctionAttr). If you have already upgraded to a version >=r286062, here are some possible solutions: 1. Don't restart X: everything should mostly keep running, since the older shared lib has already been loaded in memory. A fix for Mesa should emerge in the meantime, probably in a day or two at most. 2. Return to an older LLVM version: if you don't regularly clear /var/cache/pacman/pkg, you should be able to find there package versions earlier than r286062. 3. Switch to llvm/mesa from the official repositories. This may be somewhat tricky, depending on what exact packages you had installed. Try replacing as much as possible of the installed llvm-svn/mesa-git packages with their llvm/mesa counterparts. Remove the -svn/-git packages that don't have an equivalent 'provides' in the official repos. Of course, this might break some functionality for you. I'll also consider keeping older versions of the llvm-svn* packages in the binary repo as a backup. Ref: https://github.com/llvm-mirror/llvm/commit/4a6fc8bacf11d8066da72cf8481467167877ed16

@all : upstream changed naming of some files, this caused a build error. PKGBUILD now moves the correct files again. @gentoofu : commenting that line out would have solved the build error,but also break intel vulkan support.
