Re: [Plplot-general] Compiling against the Fortran77 libraries in PLPlot 5.10.0

[David V. <dve...@gm...>]

Thanks, Andrew.  It's OK.  This was a good exercise as it forced me to
figure out how to wrap Fortran95 PlPlot with Fortran95 code, rather than
the Fortran77 PLPlot bindings with Fortran77 code, and do it with
shared-object libraries rather than static libraries, which was a useful
and necessary exercise.  It probably seems trivial, and maybe it is, but
it's made a little less so since it all must be linked against a body of
Fortran77 code that I've no control over, and also since I'm using the
Autotools, which are beneficial but which also warrant a little extra
thought.
