I suggest adding ignition-math-6 and ignition-cmake-2 as dependencies, as the same are installed if not present in the system and can conflict with the standalone installation needed by gazebo-classic

git is missing from makedepends.

For unknown reasons, qt_gui_cpp and rqt_gui_cpp failed to built on my system. Following https://github.com/ros2/ros2/issues/1139#issuecomment-1008367494 I appended '--packages-ignore qt_gui_cpp rqt_gui_cpp' to the colcon build command towards the end of the PKGBUILD file yielding the following line: 'colcon build --merge-install --packages-ignore qt_gui_cpp rqt_gui_cpp ${COLCON_EXTRA_ARGS}'

I am trying to install this package on a Raspberry Pi 4 running manjaro minimal. I get the following error;

==> ERROR: sip is not available for the 'aarch64' architecture.

Please help

@moonaru I just fixed ros2-humble.install. Thanks for reporting the issue.

This package follows the official instructions for building from the source, so it builds and installs all the packages from these repos. The document doesn't specify whether or not the .repos file corresponds to a metapackage like ros-humble-desktop, but eyeballing REP-2001 shows that the desktop metapackage is a close-but-not-perfect match.

Anyway, one needs to understand that the Arch support is very limited compared to Ubuntu. So all the packages beyond ros-desktop need to be built manually. This notably includes xacro, navigation2, turtlebot-*, gazebo-ros, etc. Some packages (like xacro) are straightforward to build, but others (like navigation2) require some head-scratching. To help with this, I once attempted to create an additional fat package for AUR that installs common ROS 2 packages. The package is available here but I've stopped working on it. You can still use it to find out about some gotchas in the way.

Hello, I have a question again. We were able to install the full package by typing ros-humble-desktop in Ubuntu. Can we do this on Arch?

Info: Yes, it is indeed installed in /opt/ros. I'm misremembering somewhere. This information is also available on the official website.

You specified in the ros2-humble.install file as follows:

source /opt/ros2/humble/setup.bash

It should be like this:

source /opt/ros/humble/setup.bash

@moonaru We had users reporting that /opt/ros2/ can break some scripts that assume /opt/ros/ installation path. So starting from humble we reverted to /opt/ros/ to make it consistent with official packages in other distros.

Also, I'm not sure if other python versions/packages would necessarily interfere with this package but thanks for the heads-up.

You set it as /opt/ros/humble in the installation script, but normally it should be /opt/ros2/humble.

Compilation is successful, but the conditions for a smooth compilation are:

1- Install the python-pyqt5-sip4 package from aur.

2- Uninstall python36, python37, python38, python39 and similar packages and install this package. After installing this package, you can install the python packages that you have removed. (Trying to compile using python36 when getting a package build.)
