[SOLVED] Qt platform plugin "wayland"

I use Spyder in Anaconda. Running Spyder I always got warning "Could not find the Qt platform plugin "wayland" in....". Despite this, Spyder has activated so far. Since a few days the error message is the following:

 
Could not find the Qt platform plugin "wayland" in ""
libGL error: MESA-LOADER: failed to open iris: /home/xxx/anaconda3/lib/python3.9/site-packages/zmq/backend/cython/../../../../../ ./libstdc++.so.6: version `GLIBCXX_3.4.30' not found (required by /usr/lib/dri/iris_dri.so) (search paths /usr/lib/dri, suffix _dri)
libGL error: failed to load driver: iris
libGL error: MESA-LOADER: failed to open swrast: /home/xxx/anaconda3/lib/python3.9/site-packages/zmq/backend/cython/../../../../../ ./libstdc++.so.6: version `GLIBCXX_3.4.30' not found (required by /usr/lib/dri/swrast_dri.so) (search paths /usr/lib/dri, suffix _dri)
libGL error: failed to load driver: swrast
fish: Job 1, 'spyder' terminated by signal SIGSEGV (Address boundary error) 

I've read several Wiki articles and I'm sure the solution is indicated but I couldn't find it.
Any help will be welcome. Thanks in advance to everyone.

Re: [SOLVED] Qt platform plugin "wayland"

You using an outdated python version which uses an outdated C library which uses an outdated pyt5 which uses an outdated static qt5 build...

Can/have you tried updating your conda environment? Do you actually knowingly and actively need anaconda/conda instead of spyder from the repos?

I update the conda environment every time I use it. I am well aware that Anaconda is not very up to date, but unfortunately I currently have to use it.

However, if the problem is not my Arch setup, I'll find a workaround.

Thank you very much for the tips.

You could try moving away the libstdc++.so.6 mentioned there to force it to use the one from the system.

I have thought about your suggestion and will try to get rid of anaconda and use spyder from Arch's repos. Thank you again and kind regards.
