glesv2 not found

Mesa USED TO provide glesv2.pc files all the time, but now only does that when built without libglvnd support.

Mesa devs feel that whoever generates the driver/library should provide such files and I agree with them. This means that libglvnd devs need to provide them, but sofar they failed to do that.

https://aur.archlinux.org/packages/libglvnd-glesv2 is patched to provide all pkgconfig files for the drivers/libararies libglvnd builds, use that instead of stock libglvnd.

  • 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.

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.

  • issues
Simple issues can be dealth with through aur comments, but sometimes discussion is needed.
Use https://bbs.archlinux.org/viewtopic.php?id=212819 for that.
  • 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 , restart X .

run glxinfo to verify basic OpenGL functionality

build lib32-mesa-git

run glxinfo32 to verify basic OpenGL functionality for multilib programs

Read https://wiki.archlinux.org/index.php/Arch_User_Repository#Prerequisites , then check which groups bison and flex are members of.

dudemanguy commented on 2019-05-13 22:11

I think bison and flex should be added as dependencies.

Lone_Wolf commented on 2019-05-12 12:34

You do have a point that removing the _build folder should be done in prepare() to allow makepkg --noextract to work as intended.

I'll move that part of the code.

gulafaran commented on 2019-05-12 08:46

why is the pkgbuild doing "if [ -d _build ]; then rm -rf _build fi" in the build() function?

Want to change something and makepke -e? Welp, rebuild everything again! what's the point of having an incremental build system if we just nuke the build artefacts?

Lone_Wolf commented on 2019-04-28 00:02

Switched to llvm-lw-git and associated packages for llvm trunk master.

Instructions to use other llvm trunk versions will be posted soon.

Faalagorn commented on 2019-04-17 09:17

Nothing major, but I think you should also update lib32-mesa-git with latest PKGBUILD changes :)?

Lone_Wolf commented on 2019-04-12 20:46

Mesa-git now uses aur llvm-git exclusively.

If you wish to use an alternative llvm development implementation, edit the PKGBUILD.

Lone_Wolf commented on 2019-04-09 14:34

All 3 should provide the needed llvm / clang svn.

Lone_Wolf commented on 2019-04-07 16:34

Currently there are 3 possibilities for an llvm trunk version

Aur llvm-lw-git (multiple packages, tailored to my workflow)

Aur llvm-git

LordHeavy unofficial mesa-git repo

Thanks for the alert, both mpv & vlc have glslang as (indirect) dependency, so it's present on many systems.

Will add it this weekend.
