Hi
I am quite new with ros2, anyone here can help me with the following problem of compilation:

--- stderr: yak_ros
:0:1: error: macro names must be identifiers

Best regards

Could you provide some more info about your system and environment?

• Which version of CUDA are you using?
• Which OS are you using?
• Which version of ROS 2 are you using?

Try compiling with the CMake verbose flag enabled. In ROS1 you can do this with catkin build --verbose, and in ROS2 you can do it with colcon build --cmake-args " --verbose".

The last time I got an error like this I think it was because PCL 1.8 was creating badly-formatted CMake flags (I have notes somewhere but my offhand recollection is that it was creating -DAVIDSDK when it was supposed to be using -DDAVIDSDK). Look for COLLECT_GCC_OPTIONS in the verbose output and make sure the flags are correctly formatted. The solution at the time to that particular problem was to use PCL 1.9 instead.
