Micro Ros Agent won't build under Kilted

[pitosalas]

realize that Kilted is not a supported platform. But I am hoping that jazzy micro ros agent is compatible. So I am asking for a workaround. I am willing to get my hands dirty :)

mkdir ~/uros_ws/src -p
cd ~/uros_ws/src
git clone -b $ROS_DISTRO https://github.com/micro-ROS/micro-ROS-Agent.git
git clone -b $ROS_DISTRO https://github.com/micro-ROS/micro_ros_msgs.git
cd ..
rosdep install --from-paths src --ignore-src -r -y
colcon build --symlink-install
cd ~
echo "source \$HOME/uros_ws/install/setup.bash" >> ~/.bashrc
source ~/.bashrc

Fails with this.

I attempted to temporarily set ROS_DISTRO to jazzy and that didn't work.

p.s. I followed an incorrect instruction earlier and started building ROS2 from source. I think I deleted all remnants of that attempt after aborting it. But it might have left something behind that is causing this problem..

@pitosalas I checked these before. And I just checked again on humble, jazzy, kilted and rolling. It works.

Please make sure you sourced the correct ROS env.

I use docker and distrobox to test various ROS distros in separated container.

Distrobox default to use podman. I prefer docker.

mkdir -p ~/.config/distrobox
cat < ~/.config/distrobox/distrobox.conf
container_manager="docker"
EOF

distrobox create --nvidia -i ubuntu:24.04 jazzy -H ~/box/jazzy
distrobox create --nvidia -i ubuntu:24.04 kilted -H ~/box/kilted

The --nvidia option will install nvidia packages. Add this only if you use nvidia graphic card.

My base desktop is Bluefin Linux, which is immutable. The core OS is not touched. All my works are in containers or VM.

@pitosalas You can use Ubuntu as the base and install distrobox.
