[Actions Quiz] catkin_make error

Course Support ROS Basics In 5 Days (Python)

I got the following error during catkin_make:
Generating .msg files for action actions_quiz/CustomActionMsg /home/user/catkin_ws/src/actions_quiz/action/CustomActionMsg.action
CMake Error at /home/user/catkin_ws/build/actions_quiz/cmake/actions_quiz-genmsg.cmake:3 (message):
Could not find messages which
‘/home/user/catkin_ws/devel/share/actions_quiz/msg/CustomActionMsgAction.msg’
depends on. Did you forget to specify generate_messages(DEPENDENCIES …)?

Cannot locate message [Header] in package [std_msgs] with paths
[[’/home/user/catkin_ws/devel/share/std_msgs/cmake/…/msg’]]
Call Stack (most recent call first):
/opt/ros/noetic/share/genmsg/cmake/genmsg-extras.cmake:307 (include)
actions_quiz/CMakeLists.txt:71 (generate_messages)

However I should already included all necessary dependencies. Not sure what went wrong?

can you post your package.xml and CmakeList.txt, it looks like there is something missing there

The pasted code here seems to have some display issue, some code is somehow outside of screen display range. However it still includes the points I think…

This error shows that the message Header is not found. Try double checking your dependencies and remove your build and devel folders before compiling again, and then source your worskpace:

cd ~/catkin_ws
rm -rf build/ devel/
catkin_make
source devel/setup.bash
rospack profile

Anyone knows why it is necessary to do so? It’s very counter-intuitive. If there is a problem with a package, the initial catkin_make should have signaled an error not silently exit successfully.
I did as instructions suggested, catkin_make exited without error but rosmsg list | grep Custom was empty. Had to remove build/ and devel/ and rebuild for it to come up in rosmsg list

This happens if you had compiled your package before and you thereafter made changes to it.

Before re-compiling, you need to remove build and devel. Otherwise, your changes (or any errors introduced) might go unnoticed.

Thanks, but the build system itself should have managed any re-compilations if sources are changed like make and cmake do.

Well, the developers of catkin_make didn’t think that was super necessary.
You can get around that by creating a bash alias for catkin_make that does that.
