Peacock is a GUI interface in moose, which can help judge the input of model. One day, when I opened the software and found peacock, an error occurred and the error content was reported

libGL error: MESA-LOADER: failed to open r600: /home/zhaohaowang/miniconda3/envs/moose/lib/python3.7/site-packages/PyQt5/../../../libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /usr/lib/dri/r600_dri.so) (search paths /usr/lib/dri)

According to the statement on the Internet:

Similar problems

And

Matlab encountered this problem
found that the libstdc + + library of peacock did not match the system library

solve the problem

First, find the location of libstdc +

sudo find/-name "libstdc++.so.6*"

obtain

find: ‘/proc/83730/task/83730/net’: Invalid arguments
find: '/proc/83730/net': invalid parameter
find: '/run/user/1000/gvfs': insufficient permissions

Link lib/libstdc + +. So. 6 to the libstdc + + of peacock

ln -sf /usr/lib/libstdc++.so.6  /home/zhaohaowang/miniconda3/envs/moose/lib/python3.7/site-packages/PyQt5/../../../libstdc++.so.6

Then it can be spicy!
