Hi to all.
I built ngspice 23 on linux using the --enable-x switch but
the ngspice executable
run in a classic shell without any X GUI
I supposed that switch would build an executable like the
one in win32/mingw32 using
ngspice on LINUX will always compile as a console application. The X11
interface is used in the interactive mode (manual chapt. 17), especially
for plotting data (manual chapt. 18.3).
