colcon build fails on Foxy #70

Closed lukeboi closed 3 years ago

lukeboi commented 3 years ago

Hi all, I've been working with this library on ROS2 Dashing/Ubuntu 18 and today updated to Ubuntu 20 with a fresh install of ROS2 Foxy. I cloned this repo and have been unable to get colcon build to succeed. Here are the steps I've been taking to reproduce the build failure. Please let me know if there's anything else I can provide or do to get this issue fixed.

Cheers, Luke

You need to use the foxy branch, not ros2

lukeboi commented 3 years ago

Thanks for the speedy reply! I've tried using the contents of both the foxy-devel branch and ros2 branch, I get the same error on both.

You probably have something cached wrong somewhere, I just verified (output of history in my terminal):

 2004  mkdir -p hi/src
 2005  cd hi/src/
 2006  git clone git@github.com:ros-drivers/ros2_ouster_drivers.git -b foxy-devel
 2007  cd ../
 2008  source /opt/ros/foxy/setup.bash 
 2009  colcon build

builds fine

This was indeed a cache-related issue. After recompiling and reinstalling pcl the packages build fine. Thanks!
