alhp
Build script for archlinux instructionset enabled repos. All packages are build with -march=<cpu-set> -O3. Some
packages will fail to build, they will just be provided from the official repos as usual.
Check your system for support
Important: Before you enable any of these repos, check if your system supports x86-64-v3. You can do that
with /lib/ld-linux-x86-64.so.2 --help. If you don't check beforehand you might be unable to boot your system anymore
and need to downgrade any package that you may have upgraded.
Example output snippet for a system supporting up to x86-64-v3:
Subdirectories of glibc-hwcaps directories, in priority order:
x86-64-v4
x86-64-v3 (supported, searched)
x86-64-v2 (supported, searched)
Enable Repos
To enable these complement repos you need to add them above the regular repos in /etc/pacman.conf
Example pacman.conf
[core-x86-64-v3]
Server = https://alhp.harting.dev/$repo/os/$arch/
[extra-x86-64-v3]
Server = https://alhp.harting.dev/$repo/os/$arch/
[community-x86-64-v3]
Server = https://alhp.harting.dev/$repo/os/$arch/
[core]
Include = /etc/pacman.d/mirrorlist
[extra]
Include = /etc/pacman.d/mirrorlist
[community]
Include = /etc/pacman.d/mirrorlist
Replace x86-64-v3 with your cpu-set. More information about all available options on this gcc page.
Currently, alhp.harting.dev only builds for x86-64-v3 (list is subject to change).
You can see all available repositories here.
After finished adding the repos to pacman.conf you need to import and sign the used pgp key:
Import:
pacman-key --keyserver keyserver.ubuntu.com --recv-keys 0D4D2FDAF45468F3DDF59BEDE3D0D2CD3952E298
Local sign:
pacman-key --lsign-key 0D4D2FDAF45468F3DDF59BEDE3D0D2CD3952E298
Update package database and upgrade:
pacman -Suy
Remove Repos
To disable ALHP remove all *-x86-64-v3 entries in /etc/pacman.conf.
After that you can refresh pacmans databases and downgrade all packages like:
pacman -Suuy
Package eligibility
Packages excluded from building besides all 'any' architecture packages are listed in issue #16.
