Description Mike Maher 1999-02-10 16:03:24 UTC
Fortran and C apps have problems when going from f2c to g2c
libs. The file unix.c in Spice no longer compiles for
example.

a fortran app using xargc and xargv will no longer work.

g77 docs that explain the differences and using '-lg2c -lm'
instead of
using '-lf2c' and the types of changes are explained here:

<ftp://alpha.gnu.org/g77.plan>

linking with f__xargc should work according to the docs,
however I'm still testing this and I'm having trouble
compiling and getting it to work, note after my changes:

assigned to kingdon. I doubt that there are any more Spice problems or
that is anything we can do better.

this bug used to be owned by mike, now timp is the new
maintainer.

Tim, can you verify that spice now compiles okay?

Comment 2 Jim Kingdon 1999-08-30 03:12:59 UTC
Tim, did you check whether spice is now compiling?  I'm not planning
to do anything about this until someone can supply me with a test
case (or, perhaps, more hints about where to find spice - I looked
a bit for a package called "spice" in the distribution or powertools
and didn't see one).
