mesa-git-arch

A script to build mesa-git, lib32-mesa-git and xf86-video-amdgpu-git AUR packages in a clean chroot and add them to a local repository.

Usage

First, read over the script and make any modifications required for your use-case.

There are two files:

• min_mesa_git_aur_ccm.sh - clones AUR repositories, prepares local repository, launches the build script
• min_mesa_git_aur_ccm_build.sh - the build script. It exists as a separate file for conveniece. This way it can be run via sudo - making sure sudo password does not time out during a long build process.

In my use case:

$ git clone https://github.com/SirToffski/mesa-git-arch.git
$ cd mesa-git-arch
$ bash min_mesa_git_aur_ccm.sh

Requirements

The script uses clean-chroot-manager(1).

In addition, there are two separate makepkg.conf files used.

• /usr/share/devtools/makepkg-x86_64.conf is used to build:

  • python-sphinx-automodapi
  • llvm-minimal-git
  • lib32-llvm-minimal-git

• /home/$USER/makepkg-x86_64_O3.conf is used to build:

  • mesa-git
  • lib32-mesa-git
  • xf86-video-amdgpu-git

Using -O3 is not usually recommended; consider using -O2 instead.
