catkin build hangs #98

Closed joeuser846 closed 2 years ago

joeuser846 commented 2 years ago

I'm trying to install this code under Ubuntu 20.04.4 LTS and ROS Noetic on a Raspberry Pi 4. When I get to the catkin build step the process always hangs at 84%. Any ideas? Thanks.

does you raspberrypi have internet connection? it need internet to install dependencies. or if it is memory usage problem, you can change the thread number with catkin build -j 2

Thanks for your good suggestion, but that didn't turn-out to be the problem. I decided to do 'catkin clean', 'catkin init', and 'catkin build' and that resulted in hanging at 84% for about 60 secs, but then it finished with two errors: 'testresources' missing and 'numpy' wrong version installed. I resolved those errors with:

sudo apt-get install -y python3-testresources

pip3 uninstall numpy pip3 install numpy==1.19.2

The 'catkin build' now completes.
