ubuntu 18.04 compilation problems

[Qyilin]

Hellow everyone his problem has been bothering me for too long, I felt powerless to solve it.

I tried compiling the environment:
gcc-7.2.0 (I have found people who say the same problem is solved in this version)
gcc-11.1.0 (This is the latest version I could find)
And I tried commands:
cd /home/swbot/slamware/slamros/segmap_ws/build/pcl_catkin
catkin build --get-env pcl_catkin | catkin env -si /usr/bin/make --jobserver-fds=6,7 -j
catkin build -std=gun++11 --get-env pcl_catkin | catkin env -si /usr/bin/make --jobserver-fds=6,7 -j

By the way I'm not going to use the GPU version, has anyone compared whether GPU is better or not, unfortunately, I didn't even pass the compiler
Any suggestions for that? Thanks a lot!
