catkin_build error in ubuntu 20.04

[euichan2000]

I'm attempting to build Noether on ubuntu 20.04. Here is my sequence to build Noether.

mkdir -p ~/path_ws/src
cd ~/path_ws/src
git clone [email protected]:ros-industrial/noether.git
cd path_ws
vcs import src < src/noether/dependencies.repos
rosdep install --from-paths src -iry
catkin build

then, this error message appears.

I have no idea to fix this error. Any suggestions? Thanks!!
