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

I installed this Mesa, now I cannot run a lot of apps (Left 4 Dead 2, Wine) because /usr/lib(32)/libxcb-dri3.so has some undefined symbols (xcb_get_reply_fds, ...). I even tried to compile (lib32-)libxcb-git and xcb-proto-git, but nothing has changed. I am on [testing] with everything up to date. By the way I have found that Mesa can be compiled with GCC without -flto only (clang fails).

Lone_Wolf commented on 2014-01-29 20:16 (UTC)

version numbering changed to be closer to other git packages. I've decided to go back to building against llvm-svn instead of stock llvm as preparation for adding opencl support. I've tested with aur llvm-svn and mesa-git repo llvm-svn succesfully. Once i've updated the lib32-mesa-r* pacakge, i'll look into adding opencl support.

Lone_Wolf commented on 2014-01-26 16:56 (UTC)

x89 : xorg-server-devel is a makedepend of this package and pulls in glproto/dri2proto/dri3proto etc . or do you mean those are needed at runtime also ?

Naypam commented on 2014-01-20 11:44 (UTC)

More deps: 'presentproto', dri3proto.

colinkeenan commented on 2013-12-24 17:50 (UTC)

Yes - I read it but reported anyway and then un-commented all the testing stuff in /etc/pacman.conf. It's building now.

Krejzi commented on 2013-12-24 17:41 (UTC)

Well, if you just cared enough to read what I wrote - the fix is in the very first sentence: ... there is now a version of libxcb in [testing] which has all the necessarry libraries. ...

colinkeenan commented on 2013-12-24 17:37 (UTC)

ERROR: Makepkg was unable to build mesa-git. So, here's the issue: checking for DRIGL... no configure: error: Package requirements (x11 xext xdamage xfixes x11-xcb xcb-glx >= 1.8.1 xcb-dri2 >= 1.8 xcb-dri3 xcb-present xcb-sync xshmfence >= 1.1 xxf86vm) were not met: No package 'xcb-dri3' found No package 'xcb-present' found

Krejzi commented on 2013-12-24 16:06 (UTC)

I've updated the package, enabled dri3 by default since there is now a version of libxcb in [testing] which has all the necessarry libraries. I have also added, but not built by default, a seperate package which can build libOpenCL library for Radeon hardware. Just uncomment mesa-libcl-git in the pkgname section, libclc-svn dependency and --enable-opencl configure switch in build section. libclc-svn is unfortunately not buildable with clang-3.3 which is currently in arch repos. clang-svn is required for that one. If there are any issues, please report.

Krejzi commented on 2013-12-09 20:22 (UTC)

oliv, thanks, but I've updated the PKGBUILD few hours before you posted. Also, a note. Please try to send a patch against PKGBUILD later, it's easier for me to see what's changed instead of having to look for it by myself. dif -Naur PKBUILD.old PKGBUILD should do the trick.
