Build script for archlinux instructionset enabled repos.
|
|
All packages are build with -march=<cpu-set> and -O3. Some packages will not build with -O3, they will just be provided from the official repos as usual.
|
|
|
|
## Enable Repos
|
|
To enable these complement repos you need to add them above the regular repos in `/etc/pacman.conf`
|
|
|
|
### Example pacman.conf
|
|
|
|
```editorconfig
|
|
[core-znver2]
|
|
Server = https://alhp.harting.dev/$repo/os/$arch/
|
|
|
|
[extra-znver2]
|
|
Server = https://alhp.harting.dev/$repo/os/$arch/
|
|
|
|
[community-znver2]
|
|
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 znver2 with your cpu-set. More information about all available options on [this gcc page](https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html).
|
|
Currently alhp.harting.dev only builds for `znver2`, `ivybridge`, `sandybridge` and `skylake` (list is subject to change).
|
|
You can see all available repositories [here](https://alhp.harting.dev/).
|
|
|
|
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:
|
|
```
|
|
pacman -Sy
|
|
```
|
|
|
|
## Replace packages
|
|
Following command reinstalls all packages found in the repo **extra-znver2** that are already installed.
|
|
Replace `extra-znver2` with whatever repo you want to install.
|
|
|
|
```shell script
|
|
pacman -S $(pacman -Sl extra-znver2 | grep installed | cut -f 2 -d " " | perl -pe 's/\R/ /g;')
|
|
```
|
|
|
|
This is only needed once, new updates are coming from this new repo then, as usual. |
