[bug#27344] [PATCH v2 08/12] gnu: Add ngspice.

[Theodoros Foradis]

Hello Danny,

Correct. Ngspice, does not build both the executable and shared library
in the same run. The configure script must anyway be run twice, and this
is why I split the package, to begin with.

That was not intended. In the first version of the patch set, I had the
"ngspice" package copy the shared library from "libngspice" to its
output. So, there would only be one public package. After splitting it
up, I missed on fixing the duplicates.

Thanks for fixing that.

Should be in libngspice.

Should be in both packages.

Should be in ngspice.

The program I have tested libngspice with, is Kicad (after I get this
patchset over with, I will submit a patch to update Kicad, and build
with ngspice support). I guess it finds libngspice through LIBRARY_PATH
or something? Also, it builds without cmpp being in libngspice (so
libngspice is useful without it), but cmpp should be there nonetheless.

I have updated your patch, to delete the appropriate files from ngspice
and libngspice respectively. I will send it with the updated patch
series.
