Spectrum is not displaying

Hi, I am using Ccpnmr 3.1.0 and processing my data using NMRPipe. When I try to import, the spectrum is not displaying.
The following errors occurring when I open Ccpnmr.
libGL error: MESA-LOADER: failed to open iris: /home/nmrware/ccpnmr_new/ccpnmr3.1.0/miniconda/lib/python3.8/site-packages/PyQt5/…/…/…/libstdc++.so.6: version GLIBCXX_3.4.30' not found (required by /usr/lib64/dri/iris_dri.so) (search paths /usr/lib64/dri, suffix _dri) libGL error: failed to load driver: iris libGL error: MESA-LOADER: failed to open swrast: /home/nmrware/ccpnmr_new/ccpnmr3.1.0/miniconda/lib/python3.8/site-packages/PyQt5/../../../libstdc++.so.6: version GLIBCXX_3.4.30’ not found (required by /usr/lib64/dri/swrast_dri.so) (search paths /usr/lib64/dri, suffix _dri)
libGL error: failed to load driver: swrast

I am using Fedora 36 system and csh shell.
Any help? Thank you.

Hi Madhan,

which of our Linux versions are you using? In principle the CentOS7 one ought to be the best one.

In general, it looks like you might have to install opengl (again) on your system.

Hi Vicky,
Thanks for the reply. I have rectified the OpenGL installation issue. But I got the following error.

File “/home/nmrware/ccpnmr_new/ccpnmr3.1.0/miniconda/lib/python3.8/site-packages/OpenGL/contextdata.py”, line 40, in getContext
raise error.Error(
OpenGL.error.Error: Attempt to retrieve context when no valid context

Can you guide me how to solve this issue?
