Arch Linux User Repository

I tried getting 2024.04.23 working with python_qt_binding without success (none of the backends built in a clean chroot), but after the upgrade to Python 3.12, none of them will build even in my host environment. This, combined with long build times and the faster update pace of Arch compared to ROS causing dependency issues, has led me to decide to disown this package.

On a relatively fresh Arch install, this fails at

Starting >>> qt_gui_cpp
--- stderr: qt_gui_cpp

Somehow without explicit git as dependency in clean chroot:

:: Synchronizing package databases...
 core downloading...
 extra downloading...
 arch4edu downloading...

 there is nothing to do

There some other missing dependency, without clean chroot you won't now which one. I managed to build it in clean chroot with

diff --git a/PKGBUILD b/PKGBUILD

@AchmadFathoni: git is a transitive dependency through ros2-arch-deps, and as such should be installed before downloading sources

Please add git as makedepends so it can be build in clean-chroot.
