#+TITLE: Auto-build package repository for Arch Linux
|
|
* What is this?
|
This is a set of files to auto-build a personal repository for Arch.
|
It uses a chroot environment to build the packages, so that a build environment can be made on a server running a non-arch operating system.
|
|
* Set-up
|
Edit ~create_chroot.sh~ variables at the top to your details.
|
Run ~sudo create_chroot.sh~, and create the git repository in ~/build/repo~ when prompted, with a remote repository.
|
|
You may also want to set ~MAKEFLAGS="-j$(nproc)"~ within the chroot to enable parallel compilation.
|
For xz compression, add the ~--threads=0~ option to COMPRESSXZ such that it reads ~COMPRESSXZ=(xz -c -z - --threads=0)~.
|
ccache may be useful to decrease the times of git packages, due to the little changes.
|
|
* Usage
|
All scripts must be run as root.
|
To enter the chroot, use the ~enter_chroot.sh~ script.
|
To add a package from the AUR, use the ~add_package.sh~ script, with the git URL as the argument.
|
To build the packages use the ~build_packages.sh~ script, which will enter the chroot, and build the packages from the PKGBUILDs stored in ~/build/repo~.
|
|
The packages are built and put into the directory ~/build/repo/x86_64~, then pushed with git.
|
Only the latest packages are stored in ~/build/repo/x86_64~ to avoid multiple older versions building up.
|
|
To enable automatic building, create a cronjob for root, something of the sort of ~0 12 * * * /path/to/dir/build_packages.sh~ to build ever day at noon.
|
|
* To Dos
|
- Error catching for builds which fail.
|
- Create a universal variables file
