Hi Pete,
With a bit of patience, the use of macports, and GCC/Gfortran 4.4.3, I
have indeed been able to build all of 5.11.4 and I have been able to view
gridded data with gdplot2 and display the grids with gdinfo.
Let me gather my build notes together and develop a how-to that hopefully
will work for you too. Hopefully in a few days . . .
Cheers,
Kevin

All,
Has anyone had any success building GEMPAK 5.11.4 under a 64 bit environment
in OS X 10.6?
Some background -
I was able to fairly easily build a 32 bit GEMPAK using gcc-4 and g77 3.4.3,
along with openmotif3 from a 32 bit install of fink. However, the executable
files run much slower on a brand new 64 bit CPU iMac than even on a 2 year
old linux box. This includes both included GEMPAK executable files (gddiag
was one I think) and some code that the user wrote that links into various
GEMPAK libraries for reading/writing files.
One thing I noticed was that if I added any optimization level to the compile
of the user code, the calls to the gempak file open routines would return
with a -12 error (file not found, I think). So maybe there is something about
the lack of optimization that is causing it to be slow?
I also considered the possibility that I'm running 32 bit code under a 64 bit
OS/CPU, so maybe that is slowing it down. I attempted a compile using a 64
bit fink install of gcc44 and gfortran, loosely basing several of the config
files on the 64 bit linux gfortran compile. I ran into lots of undefined
routine problems, which seemed to result from certain libraries not being
included on the compile line, mostly in the drivers section (ps, xw, gif,
etc.) I was able to manually get each of these to compile by adding the
required libraries to the compile line, and much of GEMPAK appeared to
compile and install properly, but it doesn't run right. Very strange - any
program that I run, for example, gdinfo, produces the following output:
Usage: convcvg type ...
type = 3e3f, 3i3h, 3k3j, 3l3j, 3m3j, etc.
This output happens for any gempak program, or any of the users programs that
link to the gempak libraries. Very strange, since I'm running gdinfo, not
convcvg
Does anyone have any ideas or tips on getting GEMPAK to build correctly using
64 bit Mac OSX and gcc/gfortran?
Thanks,
Pete
