[Simnibs-discuss] SimNIBS 4.0 on Ubuntu 22

[Kristoffer Madsen]

This is normally because pyQt has problems with binaries on the
Wayland backend. As mentioned in changelog for 4.0, you should try
preloading your system libstdc++.so.6 (from a terminal, prior to
running simnibs_gui):

simnibs_gui does not start on some linux systems, e.g. with wayland
(workaround: ld preloading of libstdc++.so.6 seems to help; example:
export LD_PRELOAD=/usr/lib/libstdc++.so.6 - path needs to be adjusted
according to library path on local system)

I would be nice if you could confirm if this works or not.

Best,
Kristoffer
