Hi, even after sourcing and all the path is included correctly, I get this error while I try to compile (few other projects compiles well from the same workspace directory that which includes rclcpp.hpp ) version-dashing on 18.04

/home/snvk/ros2_dashing/src/ros2_fr/src/fr_subscriber.cpp:2:10: fatal error: rclcpp/rclcpp.hpp: No such file or directory
 include "rclcpp/rclcpp.hpp"

compilation terminated.

gmake[2]: *** [CMakeFiles/subscriber.dir/src/fr_subscriber.cpp.o] Error 1
gmake[1]: *** [CMakeFiles/subscriber.dir/all] Error 2
gmake[1]: *** Waiting for unfinished jobs....
gmake: *** [all] Error 2

Failed   <<< ros2_fr    [ Exited with code 2 ]
Summary: 0 packages finished [3.39s]
  1 package failed: ros2_fr

  1 package had stderr output: ros2_fr

Thanks in advance

Could you show your CMakeLists.txt? Please remove all the boilerplate comments from it (lines starting with #) before you post it.

I don't see a problem with the CMakeLists.txt. Can you provide your package.xml as well?

The package.xml looks ok as well. But I just noticed that your compile error is for fr_subscriber.cpp. That isn't in your CMakeLists.txt. It only contains fr_publisher.cpp. Did you provide the wrong CMakeLists.txt? How does the fr_subscriber file get built?

This CMakeLists.txt looks OK as well.

However, the files you've posted don't all match with your error messages. The project in the error message is ros2_fr, the project in the CMakeLists.txt is fr_ros2 and the project in the package.xml is frgen_ros2

Please make them consistent, and check you've posted the right files.
