otherwise packages get installed in /root/.local/lib/python3.7/site-packages

Haha, and that's why I don't run these scripts 😖.

What would be a better way to get reasonable compilation times? If you run it on default you can come back next working day to see the compilation result.

Ok, so my opinion is that if you're using Arch that's probably something you should figure out yourself (by googling and looking at the Arch Wiki).

Arch == no convenience allowed? 😝
At least Manjaor I actually find even more convenient than Ubuntu, it does similar stuff but right.

Yer not sure 🤔

Strange, I didn't have this problem.

The package maintainer screwed up something in the meantime. I didn't understand the process of how to contribute but I'll send him a message and we can take it out as soon as he fixed it.

Update: I commented on the AUR to hopefully get the ignition-cmake fix in such that we can skip the workaround in the future: https://aur.archlinux.org/packages/gazebo/#comment-711597
Describe problem solved by the proposed pull request
Gazebo is not an official package for Arch Linux but there's a community driven AUR https://aur.archlinux.org/packages/gazebo/ that can be installed with a helper program yay https://github.com/Jguer/yay which is an officially supported package.
Describe your preferred solution
I notices that running pip as sudo on Arch is not a good idea. It installs the python modules in a different location
/root/.local/lib/python3.7/site-packageswhich depending on your environment can be inaccessible later on.I made an
--gazebooption to the arch setup script that is disabled by default. If it's passed as parameter I install all the official libraries that PX4 needs to simulate with gazebo e.g. protobug, eigen... also yay which automatically builds gazebo from source using the AUR description. There's a small workaround necessary because apparently the AUR description contains one single error.Test data / coverage
Tested on fresh install Manjaro VM:
Disadvantage: It takes a couple of minutes to compile gazebo and all its dependencies.
