FAQ

1. My catkin_make complaints missing header files. What happened?

Few possible reasons.

• There is missing apt dependent package. Try to "google" what is missing and install it.
• Racing conditions due to multithreading cmake. Try to rebuild the workspace by deleting the devel and build folder. Use catkin_make -j1.

2. All cameras does not work in simulation. How to solve?

Remove the gazebo_ros_pkgs in learning_ros_external_pkgs_noetic. Recently the ros-noetic-gazebo-ros-pkgs apt deb package is up-to-date and that one from learning_ros_external_pkgs_noetic is outdated. You should rebuilt your workspace for safe. Take a break and it take a while.

rm -rf $HOME/5755_ws/src/learning_ros_external_pkgs_noetic/gazebo_ros_pkgs
rm -rf $HOME/5755_ws/devel
rm -rf $HOME/5755_ws/build
catkin_make -j1
