OK. I think I have it.
Using your latest instructions, I get cairo and wingcc drivers.
I didn't do anything about -lm to get things to work ???
When it worked before, I had to delete -lintl ???
Lots of names changed by having to drop the "d" at the end.
I assume I was doing a double precision build.
I nominate you for Amazing Remote Debugger. (Maybe I
could do some of that with a Fortran program, but not this
kind of stuff.)
Thanks again for all the help. Plplot is going into the next
Fortran Tools, but I don't yet much info about using it with
cairo. I must suspend the fun stuff as I have a little job to
"modernize" 1,000,000 lines of Fortran code.
I still would welcome comments on that attempt to use
Plplot.
