ncelab: *f,interr: internal error
I'm not sure what's the exactly reason for this, just share my experience.
suppose you have 2 lib files with the same name, say, libgcc.so.1, one is provided by linux system distribution, the other is provided by EDA tool you installed. So the path for them are:
/lib/libgcc.so.1
/edatool/lib/libgcc.so.1
normally, the former one is much newer than the latter one, and the EDA tool is only supported by the latter one.
in LD_LIBRARY_PATH, you must put the latter path in front of the former one, so that the EDA tool can load the correct file.
