Re: [Ngspice-devel] bug fixes

Hi holger

I think it is good to release now. I know that there are some issues that
are not yet addressed, but it is not big enough IMO to delay it.

Yes, we can not build under mingw yet. I believe that windows users are
mostly interested in binaries or can carry on using plain ngspice rather
tclspice for some times. Perhaps the full integration of libtool can be put
in the release 19 task list?

I appology for my lack of time. I wanted to actively support tclspice
integration but my work does not let me the time, and I don't have windows.
If we want to do it good, better to take the time for it and wait newt
release.

Something I was thinking about in the past was to use libtool only in the
case of tclspice compiling. Perhaps it is better for ngspice. I had problems
under debian 64bits without libtool. I think we should keep it. We have to
make it compile under windows. That's true.



I fixed many warning this week, but I failed to fix the llabs implicit
declaration. llabs seems to be in stdlib, but depends on a #ifdef. Don't
have a solution yet.
It occurs for both ngspice and tclspice.

I checked warnings that appear under tclspice, but there are some others
under ngspice. Need to check it too...
