Package Maintenance

This repository allows PKGBUILDs to be maintained in the AUR for corresponding Skycoin github repos.

The old method of managing AUR packages

git clone ssh://[email protected]/$PACKAGE.git
updpkgsums
makepkg --printsrcinfo > .SRCINFO;
git add -f PKGBUILD .SRCINFO
git commit -m "commit message"
git push

with aurpublish and a containing github repository this becomes

# initial setup step, pull package from AUR
aurpublish -p $PACKAGE
#change some files
updpkgsums
makepkg --printsrcinfo > .SRCINFO;
git add -f PKGBUILD .SRCINFO
#add scripts, etc.
git commit -m "commit message"
#push to AUR
aurpublish $PACKAGE
#push to github
git push

Needed dependencies for maintainers: pacman-contrib (updpkgsums) & aurpublish

Testing builds

Packages are buildable with makepkg on arch linux, the task of handling build dependencies is fulfilled by the system package manager; pacman

From within any subdirectory containing a PKGBUILD (i.e. the desired repository or package to create)

makepkg -sf

Installing from AUR

The build and installation process is fully automated with the help of yay Here is an example of the installation process for the skycoin official release binaries:

The package was built and installed according to the functions defined in the PKGBUILD. For skycoin-bin, only the package() function is used. The source for the release is checked against its sha256sum.

Packaging Notes

basic limits-

  • makepkg cannot be run as root
  • no installing into a user's $HOME folder

Standardization and etiquitte-

  • don't rely on makepkg internal functions
  • declare additional variables with leading _underscore

Specific guidelines for skycoin packages-

  • The installation directory should be a subdirectory of /opt
  • Do not ever use inbuilt skywire updater with a package
  • Scripts are provided to enhance user experience and provide automation

Naming Conventions and build specifications / types

  • Binaries are statically compiled with musl now by default
  • -bin denotes a package which uses official release binaries.
  • without suffix, a package is built either from the source archive of the latest release or from the default branch if no source archive exists

Within the cloned AUR repository, a few variations of the PKGBUILD are sometimes included

  • deb.PKGBUILD build debian package
  • cc.deb.PKGBUILD build debian packages for all architectures
  • git.PKGBUILD build using cloned .git sources

Skywire packaging overview

The goal of the skywire AUR package is to have only one command between the running system without skywire and the running instance of skywire. Even without the existance of a hosted release package. The build / install is handled by yay and the configuration is defined in the skywire-autoconfig script which is called by the .install script at the point of installation.

deb.PKGBUILDS

Debian packages can now be natively created with archlinux packaging tools.

A typical example of building a debian package on archlinux

Fiirst, install the package with yay to the archlinux host system

yay -S skywire-bin

switch to the directory where the package was compiled in yay's cache and run makepkg on the deb.PKGBUILD

cd ~/.cache/yay/skywire-bin
makepkg -p deb.PKGBUILD

The debian package is produced.
