[humble-devel] build fails on rosdistro build farm: spinnaker download not working

[berndpfrommer]

Seems like the first rosdistro build has run against the humble-devel branch.
Here is a link where you can find the log files

It fails with the below error message when trying to download the spinnaker SDK.

The os_code_name is obtained by lsb_release -cs in DownloadSpinnaker.cmake. Apparently lsb_release either does not exist or return an empty string such that sys.argv[3] is undefined. Apparently lsb_release works just fine for the noetic-devel branch .
@fazzrazz, @tonybaltovski do you have any idea how to fix this?

After PR #116 has been merged, the log file now shows that lsb_release is not present.
Why not?

@berndpfrommer I am going to merge #119 to get this building and try to figure this out when I get more time.

[berndpfrommer]

@tonybaltovski sorry I have some newbie questions:

1. do you have to bloom release the package every time just to test if the modified code compiles on the ROS build farms?
2. along these lines: do you want me to do the bloom release (and do I even have the permissions to do so)? I am just learning the ropes with bloom etc as I'm moving my first ROS package (an event camera driver) into rosdistro.

Thanks,
Bernd

1. Generally no, usually if it builds on the CI it works on the buildfarm but something is up with this
2. Sure that would be great! I can help you too if needed.

The latest error is this. PR forthcoming...

@tonybaltovski With respect to pushing into the development branch, the flir_camera_driver repo behaves differently from another repository that I'm working with (ros-event-camera/metavision_driver). There, the ROS2 build farm polls my master branch once an hour and automatically rebuilds if new commits have arrived. That avoids opening a new rosdistro PR for every attempt to debug a build issue.
If you know how to get the flir_camera_driver repo to behave the same way, please let me know. Is the ROS2 build farm polling a different branch maybe?

Now the ffmpeg libraries are missing. Will be fixed in next PR

Now amd64 builds, but arm64 fails due to Spinnaker SDK binaries not being available for that platform.
