This repository holds PKGBUILD files for the AsahiLinux Arch Linux Arm distribution. This will hold packages which are required to run Arch Linux Arm on Apple Silicon based computers, starting with patched Linux Kernel builds with hardware support.
To do this we can inspect their spec files:
# rpm-tools are required
sudo pacman -S rpm-tools
# For example, to get the Asahi Fedora 41 spec (you should of course use the latest Fedora Asahi one)
curl -O https://copr-dist-git.fedorainfracloud.org/cgit/@asahi/mesa/mesa.git/plain/mesa.spec?h=f41
# Usually you want the spec file for aarch64
rpmspec --target=aarch64 -D'autorelease 1' -D'changelog changelog' --parse mesa.spec | cat -s > mesa.spec.aarch64
# For the mesa x86_64 overlay you should also run:
rpmspec --target=x86_64 -D'autorelease 1' -D'changelog changelog' --parse mesa.spec | cat -s > mesa.spec.x86_64
# Same for mesa i386 overlay
rpmspec --target=i386 -D'autorelease 1' -D'changelog changelog' --parse mesa.spec | cat -s > mesa.spec.i386As you can see, you can override placeholders in the spec files via the -D flag.
Usually following placeholders are interesting (extracted from the mesa spec):
_arch
_isa
_datadir
_includedir
_libdir
_sysconfdir
Most of them should be set by correctly by --target anyway, but we may want to override specific ones if needed.
I recommend to grep a spec file to see if you could override others (here only looking for ones that start with underscore %{_):
grep '\%{_' file.spec
To make things easy we set up a update-spec-files.sh script in this repo which fetches and renders spec files of Fedora packages and saves them in a fedora-specs folder of a package in this repo.
