catkin build error

[lockedandloadad]

Hello. I had been searching for a px4 exploration package and found your repository.
Thank you for your resource!
But as I tried to build mavros_visp_ompl_exploration, the error occured when compiling px4_planner.
In file included from /catkin_ws/src/mavros_visp_ompl_exploration/px4_planner/src/fly_action_server_main.cpp:2:0:
catkin_ws/src/mavros_visp_ompl_exploration/px4_planner/include/px4_planner/fly_action_server.h:22:10: fatal error: qr_detector_pkg/qr_detection_msg.h: No such file or directory
#include <qr_detector_pkg/qr_detection_msg.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
make[2]: *** [CMakeFiles/fly_action_server.dir/src/fly_action_server_main.cpp.o] Error 1
make[1]: *** [CMakeFiles/fly_action_server.dir/all] Error 2
make: *** [all] Error 2

I am not familiar with programming in general and am new to ROS, so maybe I did something wrong.
But I hope to know if there should have been a qr_detection_msg.h file in qr_detector_pkg.

Hello, sorry for the late reply. This is a common problem with ROS packages, basically the compiler doesn’t generate first the msg file so when the main.cpp include the header file of the messages an error appears because the header file of the message still doesn’t exist. A common workaround for all these problems is to comment in the catkin make all the .cpp file, so the compiler is forced to generate the msg file. After that uncomment the .cpp file and compile another time, now everything should work. Best regards, Alessandro
