I am not using recent KDE, but I recall it had it's own variables for the libraries. Might be you need to read docs. What I think will work (always worked for me) is set LD_LIBRARY_PATH=/usr/local/lib kicad or export LD_LIBRARY_PATH=/usr/local/lib kicad also check that library /usr/local/lib/libngspice.so.0 is not a dead link for example it should point to libngspice.so.0.0.0 as this is what is requested. regards
