when I did catkin_make,I got the bellow error. I made msg file. But it said that there is no message. How can I solve the peoblem?

CMake Error at /opt/ros/kinetic/share/catkin/cmake/assert.cmake:20 (message):
  Assertion failed: file
  '/home/robot/catkin_ws/src/ndt3d/msg/　　humansArray.msg' does not exist.

I wrote like bellow in CMakeList.txt

add_message_files(
  #DIRECTORY
 # msg
  FILES
  NDTResult.msg
  StampedArray.msg
  humansArray.msg
)

error:

Did you forget to specify generate_messages(DEPENDENCIES ...)?

If your custom message depends on other ROS messages (like geometry_msgs/Pose.msg ), you need to add them in your CMakeLists.txt as follows:

generate_messages(
  DEPENDENCIES geometry_msgs ...
)

It would be helpful if you post your humansArray.msg file.

Looks like you have just Pose instead of geometry_msgs/Pose in your humansArray.msg file. Please post it!

Inside humansArray.msg:

Header header Pose[] poses

float64[] id

I mistook inside msg file. I changed "Pose[]" to "float64[]". Then I could do catkin_make.

Thank you

Can I use Pose[] in my own msg?

Do you mean geometry_msgs/Pose?
