CMake Error: /catkin_ws/build/catkin/catkin_generated/version/package.cmake returned error code No such file or directory
I'm trying to do catkin_make with python3 on Arch Linux, but I get this error:
CMake Error at /opt/ros/melodic/share/catkin/cmake/safe_execute_process.cmake:11 (message):

returned error code No such file or directory

Can anyone please help me solving this issue, seems some part of catkin wasn't generated before.
can you check which of those files doesn't exist?
/home/oskar/workspace/catkin_ws/build/python3seems suspicious to me: do you have apython3binary in/home/oskar/workspace/catkin_ws/build?The file pacakge.cmake doesn't exist. And since
catkin_makenever finished successfully, there neither a py3 nor py2 binary in the folder. I always used this catkin flag:catkin_make --cmake-args -DPYTHON_EXECUTABLE=python3So this
/home/oskar/workspace/catkin_ws/build/python3exists?But
/home/oskar/workspace/catkin_ws/build/catkin/catkin_generated/version/package.cmakedoesn't?None of both files exist.
Then I would assume the immediate problem is
/home/oskar/workspace/catkin_ws/build/python3./home/oskar/workspace/catkin_ws/build/catkin/catkin_generated/version/package.cmakeis a later problem.Do you know which package is mandatory for the python executable?
I don't understand your question.
python3should probably be provided by your OS.The issue may be that for some reason, the CMake macros/functions are expecting a
python3binary/link to be present in thebuildspace. That may be perfectly normal for Catkin to do, I don't know. I doubt it though.So I'll do a little bit research tomorrow trough cmake's python linking. Thanks for your suggestions.
