catkin_make errors

[r8drfn89]

I have done everything I can to install the ROS dependencies and now I am getting this error when trying to run catkin_make

~ /ros_catkin_ws/src $ catkin_make Base path: /home/astro-scout/ros_catkin_ws/src The specified source space "/home/astro-scout/ros_catkin_ws/src/src" does not exist

[deyouslamtec]

please run catkin_make in ~ /ros_catkin_ws

@deyouslamtec This is the error after running catkin_make in ~ros_catkin_ws

I even have the empy installed

@deyouslamtec I tried this catkin_make -DPYTHON_EXECUTABLE=/usr/bin/pyhton3 -DPYTHON_INCLUDE_DIR=/usr/include/python3.7m and it gave me this message.

So I tried doing what it recommended catkin_make_isolated -DPYTHON_EXECUTABLE=/usr/bin/pyhton3 -DPYTHON_INCLUDE_DIR=/usr/include/python3.7m and it gives this error

@deyouslamtec do you understand what is going on?

[deyouslamtec]

Can you tell me your device information and OS version？

@deyouslamtec I am currently using ubuntu 20.04 on the raspberry pi 4 armhf. I was able to get further in the catkin_make process than before but now I am facing other errors. Here is the output from the /home/ubuntu/ros_catkin_ws/build/CMakeFiles/CMakeError.log"

@deyouslamtec I got it to work by getting a new sd card and installing the 64bit version of Ubuntu 20.04 onto my raspi 4. Then I used http://wiki.ros.org/noetic/Installation/Ubuntu again, along with your video. It helped a lot and it now works. Thanks for all of your help.
