It seems it could not find libqSlicerApp.so, file that is present of course.

If I set LD\_LIBRARY\_PATH to ./lib/Slicer-4.11, it outputs similar results but for every library it tries to load.

Now I don’t have any kind of special setup on that particular machine.

I’m ready to try with a debug build, but won’t be able to do it before a few days.

Thanks.
