Bootlin provides a large number of X86_64 Linux's toolchains targeting a large number of architectures for the glibc, musl and uClibc-ng.
Unfortunatly, Arch Linux is very limited in offering cross compiler binary packages.
aur-bootlin-toolchains is a repository to generate and maintain the PKGBUILD
files of the toolchains provided by Bootlin for the AUR repository.
Note: The toolchains exists in two versions (stable and bleeding edge), for three libc's (glibc, musl and uClibc-ng) and for not less 45 differents architectures. There are 207 toolchains to maintain as of version 2023.08-1. It is too many of them to spam the AUR repository with toolchains that would be used by no more than 5 developers. Therefore, the more relevant pre-built toolchains are going to be hosted on AUR; the others live somewhere on my laptop. It is not decided yet if the stable or the bleeding edge versions and which couples of libc/architecture will be pushed to AUR.
First, fetch the sources:
$ git clone git@github.com:gportay/aur-bootlin-toolchains.git
And go into the source tree:
$ cd aur-bootlin-toolchains/
Then, make the package for your favourite toolchain (aarch64-glibc-stable for
example):
$ makepkg -p PKGBUILD-aarch64-glibc-stable-toolchain

Finally, install the toolchain:
$ sudo pacman -U aarch64-glibc-stable-toolchain-2023.08-1-x86_64.pkg.tar.zst

The PATH variable will be updated on re-login. To immediately load it:
source /etc/profile.d/aarch64-glibc-stable-toolchain.sh
Important: Re-login to your user session, or source the profile script in every terminal to run the toolchain binaries without its absolute path:
$ source /etc/profile.d/aarch64-glibc-stable-toolchain.sh
Run the compiler:
$ aarch64-buildroot-linux-gnu-gcc --version
aarch64-buildroot-linux-gnu-gcc.br_real (Buildroot 2021.11-8547-g7e65a1a) 12.3.0

First, update RELEASE to the new release, reset EXTRA_RELEASE to empty, and
touch *.in files.
Then, update ARCH list of architecture to add (or remove) new toolchains, and
eventually set <arch>_<libc> or <arch>_<libc>_<version> to 0 to disable
variant if it is part of the new release.
Finally, add the changes git add PKGBUILD-* hooks.install-* profile.sh-*,
commit them git commit -m "Bump 2023.11" and tag it git tag "v2023.11-1".
Before doing anything else, the existing AUR repositories are submodules and they SHOULD be cloned:
$ git submodule update --init
After a bump, run:
$ make commit
Note: The git repository is created locally if it does not exist yet and it is not an existing AUR repository.
Eventually, make the packages:
$ make makepkg
Or, for AUR packages only:
$ git submodule foreach makepkg --force --clean --cleanbuild
In the very end, push the changes to AUR:
$ git submodule foreach git push
And commit the submodules changes:
$ git commit -m "Update submodules"
