livox_ros_driver/CustomMsg.h

[yuchuxiang]

fatal error: livox_ros_driver/CustomMsg.h: No such file or directory #include <livox_ros_driver/CustomMsg.h>

缺少这个头文件是什么情况，在原程序包中也没找到这个livox_ros_driver/CustomMsg.h头文件，这个怎么解决？

你解决了这个问题没

在devel/include里面，不是源程序包的而是compile产生的

我也遇到了相同的问题，解决办法是删了build和devel文件夹，多编译几次

There is a dependency in the CMakeFile missing. Add this line to ensure the livox_ros_driver messages are compiled first. add_dependencies(r3live_LiDAR_front_end ${catkin_EXPORTED_TARGETS})

I did not understand what you said; However, I feel your answer related to my question. I installed r3live. I want to use it. When I type rostopic hz /livox/lidar, it says:

ERROR: Cannot load message class for [livox_ros_driver/CustomMsg]. Are your messages built?

Can you explain how can I fix that?

Thank You,

Hi @farhad-dalirani, This means that the livox_ros_driver/CustomMsg is not compiled. Have you compiled the livox_ros_driver? Have you sourced your ros_ws afterwards, e.g. source ~/catkin_ws/devel/setup.bash?

[farhad-dalirani]

Thank you, source ~/catkin_ws/devel/setup.bash did the job.

I used your method but encountered a new problem

CMake Error at CTLO/CMakeLists.txt:22 (add_dependencies): add_dependencies called with incorrect number of arguments

It seems like there are some issues with "add_dependencies" can you tell me the answer
