Hi!

I solved this issue. (foxy)

First, there's no rosidl_get_typesupport_target function in foxy. So, visit here, and replace the function to the raw code in CMakeLists.txt . (You should delete PARENT_SCOPE parameter in the code)

Second, in my case, tf2_eigen and tf2_geometry_msgs are .h, not .hpp. So, rewrite lib name in src/include/lio_sam/utility.hpp.

Hi @godic97 , how do you

replace the function to the raw code in CMakeLists.txt .

I just pasted the code from the link, after this line rosidl_generate_interfaces(${PROJECT_NAME} "msg/CloudInfo.msg" "srv/SaveMap.srv" DEPENDENCIES std_msgs sensor_msgs) and got the files name error. Once I made colcon build I got

fatal error: lio_sam/msg/cloud_info.hpp: No such file or directory

    2 | #include "lio_sam/msg/cloud_info.hpp"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

So... I think I did something wrong
