Re: Linking with OSX, Absoft

Hi Irv,

It sounds like you are trying to use some precompiled NCAR Graphics
binaries for your MacBook? If so, these binaries were built with g95
and that's why "ncargex" is trying to use g95 ("ncargex" itself
doesn't use g95, but it calls "ncargf77" which does).

You can do one of two things here: you can try to modify "ncargf77"
(which is in $NCARG_ROOT/bin) so that it uses the compiler you want,
and to remove the reference to "-L/sw/lib". Or, you can try to build
NCAR Graphics from source code using the Absoft compiler.

If you go with the first option, you will need to get your Absoft
compiler to correctly link with gcc/g95-compiled NCAR Graphics
libraries. If I remember correctly, the Absoft compiler does things a
little differently with regard to how it stores Fortran routine names
in a library, so you have to include special options in order for it
to look for symbols as the g95 compiler would expect them to be. This
is why you are getting the undefined symbols like "_CPGETI". The g95
compiler stores this symbol as "cpgeti_" in the libncarg.a library,
whereas the Absoft compiler is apparently expecting it to be
"_CPGETI". This is known as "name mangling". Unfortunately, I can't
remember what the correct option is to fix this name mangling so that
the Absoft and g95 compilers are looking for the same internal
names. Does anybody else out there know?

As for compiling NCAR Graphics using the Absoft compiler: I have not
tried this on a Mac, so I don't know what kind of success you'll
have. Perhaps somebody else on this list can provide some tips.
