Al,
  With respect to:
"We do need a serious viewer for analog simulation data.  The best we
have is gwave, which has compiling issues, and it still does only
waves.  "gtkwave" does not do analog in a reasonable way, or handle any
file format used by any analog simulator."

Have you even TRIED kjwaves?
Kurt

That looks like a Mandriva problem.  The package managers are supposed
to take care of this kind of problem.  You should file a bug report
there.

I would not expect the SuSE package to work.  Those packages are built
for a particular distribution.  Crossing over sometimes works,
sometimes doesn't.  The universal package is the original source
package.  Even there, the original creator cannot test on all systems,
but will usually help on other systems.

One problem with gwave is that it has not been actively maintained.  We
had a SOC proposal to make a replacement for it, but it didn't get
funded.

This tells me again that it is a Mandriva problem.  It also tells me
that the problem is probably in the guile-1.6 package.  You should file
a bug report with Mandriva.

This tells me again that it is a Mandriva problem.  Guile-1.6 and 1.8
should be able to co-exist on the same system.  They do, easily, on
Debian.

Probably true.

You didn't mention gnucap, so I assume it installed fine, and it is
the "glue" packages that are giving you trouble.

From what I see on the web, the Mandriva gnucap package is rather old,
and a development snapshot.  That particular snapshot is a 0.35 release
candidate, so it should be close enough to not give you trouble, but it
is worthy of note that it too is in need of maintenance.

We do have a problem with the glue associated with simulation.  Our
simulation itself is quite strong, but it doesn't look that way because
of the glue problems.  There were several Google-SOC proposals to do
something about it, but none of them were funded.  There have also been
other proposals to do something about it, but none resulted in any
action.

We do need a serious viewer for analog simulation data.  The best we
have is gwave, which has compiling issues, and it still does only
waves.  "gtkwave" does not do analog in a reasonable way, or handle any
file format used by any analog simulator.

We also need to work on translation issues.  Only a small subset of what
can be on a schematic is properly translated.  On another side, we have
everything in place to do signal integrity simulations of layouts,
except the translator.

Gnucap needs a decent tutorial.  In the last year, I put it off to
concentrate on plugin code instead, which could totally change it.  Now
that the plugin system is mostly working, I expect to do a real
tutorial to be part of the next stable release.

So, this is a plea for help in two areas ...

1. Help with the simulation glue.

2. The Mandriva packages.

Any takers?
