build issue on Buster

[SarahWicker]

hi I followed the steps to install the spinnaker driver on Debian, i installed the melodic version of ROS following this tutorial: https://www.instructables.com/id/ROS-Melodic-on-Raspberry-Pi-4-RPLIDAR/ (until the RPLIDAR part since didn't need it ^^')

in a workspace installed image_common(git repository), pointgrey_camera_driver(git repository but ask catkin to ignore pointgrey_camera_description and pointgrey_camera_driver) and finally flir_camera_driver(git repository) but i get an issue at the build:

does anyone know how to resolve this issue? best regards Sarah

Hi Sarah, you shouldn't need to ignore packages. Make sure all the dependencies are installed before trying to compile. The newest changes could help with melodic compilation as well.
