Hello all!

My name is Orestes Mas and I'm a teacher of Circuit Theory at the
Politechnic University of Catalonia, in Barcelona.

I'm a newbie in the linux world, but I've had no fear of downloading,
compiling, instlling and running ng-spice (rework 12) in my computer. My
goal is to make SPICE simulations available to my students (and to
everyone else) through internet, so I've written a pair of
Applet-Servlet java programs that allow the user to introduce a circuit
description file inside a browser, send it to my Linux server (who sends
it to ng-spice for simulation) and send the simulation result back to
the user through internet.

The work is in a preliminary stage, but at this point it works for the
text-only output (you can test it, if you want, at the URL
http://colpitts.upc.es/SpiceApplet.html, but be aware because the server
can be down frequently).

In the compilation process of ng-spice, all has been done correctly,
except one thing: When I start ng-spice in interactive mode, I get the
message "external error: no graphics interface; please check compiling
instructions".

Doing so, I've run the "configure" script with the option "--with-x",
and the lib/ and include/ directories of the X-window system correctly
set, but the "configure" script doesn't seem to find the X subsystem.

Am I doing something wrong? May I expect ng-spice to be an X
application? (I've seen in your web that ng-spice is a command-line
application; OK, but nutmeg is an X-window one, isn't it?)

Thanks in advance

Orestes
