Cannot compile on ROS melodic - RPI4

[phil123456]

Hi

I just try catkin_make and it fails to compile (I use ROS melodic on a RPI4)

any help appreciated

-- +++ processing catkin package: 'rplidar_ros'
-- ==> add_subdirectory(rplidar_ros)
-- Could NOT find sensor_msgs (missing: sensor_msgs_DIR)
-- Could not find the required component 'sensor_msgs'. The following CMake error indicates that you either need to install the package with the same name or change your environment so that it can be found.

  Add the installation prefix of "sensor_msgs" to CMAKE_PREFIX_PATH or set
  "sensor_msgs_DIR" to a directory containing one of the above files.  If
  "sensor_msgs" provides a separate development package or SDK, be sure it
  has been installed.

after a lot of digging and help from "Ros Answers"...

• I cloned manualy some packages
• I ended up using ros build tools
• I added a dependecy to std_srv package

Hi Phil,
I have been having problems with the catkin_make of rplidar_ros, too.
I have ROS Melodic, RosOnWindows. Been working fine for ~6 months.
I actually have the exact same problem as issue #91 .
No one has responded to that issue.
But, I saw that you had made it through your problem.
I read your conversation concerning adding the dependency for std_srvs, etc. (ROS answers)
So, I already modified my code to do that.
I was wondering what packages did you clone manually?
And how did you get past the node.cpp errors?
Here is the link to 91: #91

Any help would really be greatly appreciated. Thank you, Smitty

Having this same issue under ROS Noetic on Ubuntu 20.04. Would appreciate a response from the maintainers.

I solved this problem on my RPi4 by doing "git clone https://github.com/ros/common_msgs.git" into my ~/ros_catkin_ws/src/ros directory. Then I rebuilt everything by running catkin_make from ~/ros_catkin_ws
