o suppress this warning ignore these packages in the workspace: --packages-ignore camera_calibration_parsers camera_info_manager --- stderr: camera_ros

I am not sure what wasn't found everything seems to be in the CMakeLists - but although libcamera is installed, it appears not to work.

Your installation of libcamera might be installed in a non-standard path or the libcamera.pc file might be missing, Note that the Ubuntu package (libcamera-dev) installs a camera.pc, while the upstream project installs a libcamera.pc. The ROS package is looking for the libcamera package and not the camera package.

With colcon-meson, you can now build the libcamera upstream repo as part of your workspace. If you install colcon-meson via pip and setup a workspace with libcamera (https://git.libcamera.org/libcamera/libcamera.git) and camera_ros, then this should work.

Otherwise, you can just globally install libcamera from https://git.libcamera.org/libcamera/libcamera.git and this should then also work.

Also, note that the libcamera API isn't stable yet and does change over time. I am rebasing and force-pushing my repo to adapt to these API changes and to incorporate other fixes. Expect the git repo and the code to break once in a while. I will change this once the API stabilises or too many people complain about breaking the git history :-)

Thanks. Since no one else has posted issues, I wasn't sure this repo was still active.

I also tried the raspicam2 node, but since I can't get raspistill working, I guess that's a non-starter. BTW I did get the Noetic raspicam_node working on ARM64 Ubuntu 20.04 on a PI 4.

The old API for interfacing with the camera on the Raspberry Pi is deprecated. So this will only work for older distributions. Eventually, you will have to switch to the libcamera stack.

Anyway, since you found a workaround, I am going to close this. If you still encounter issues with building the node due to libcamera dependency issues, just reopen this.
