A lot of ROS_NOBUILD
To learn ROS, I follow Learning ROS for Robotics Programming and use the sample code from GitHub.
( https://github.com/AaronMR/Learning_R... )
However,
I got a lot of ROS_NOBUILD when rosmake chapter2_tutorials. The packages with ROS_NOBUILD include catkin, cmake_modules, genmsg, rosclean, rosgraph, etc.
Does it mean rosmake fail to build chapter2_tutorials?
Thank you for taking time on my question.
