Hi The Construct Team,
I am learning GTest Framework for ROS2 course. I am currently on Unit 3 - Test Subscribers and Publishers using Google Test.
In section 3.1, “Build and install”:
colcon build --packages-select distance_control - this command fails.
Expected Output: (as specified in the notes)
Starting >>> distance_control
Finished <<< distance_control [21.0s]
Summary: 1 package finished [21.6s]
(Current) Actual Output:
Starting >>> distance_control
Failed <<< distance_control [14.2s, exited with code 2]
Summary: 0 packages finished [14.3s]
1 package failed: distance_control
Copy-pasted all the provided codes from the notebook “as-is” without any modification, but the build fails. Also verified package and folder structures - they are fine.
Please help.
Thanks,
Girish
EDIT: Rebuilding with colcon build --packages-select distance_control --event-handlers console_cohesion+ produces the following message:
