[Wrf-users] Cannot read a GRIB file using "gribprint.exe" (WRFSI problem)

[AMEC Weather]

Good morning,
 
We're trying to get WRF, WRFSI going on a Dell system (Pentium 4 processor,
Fedora Core 1, "little-endian").
 
We've experimented with the Intel FORTRAN and PGI FORTRAN compiler.
 
Some notes...
 
WRFSI code can be compiled using Intel FORTRAN (ifort 8.1), but several
changes to the makefiles must be made, and we found
it necessary to rename Fortran source code, e.g.,   <file>.f  to <file>.f90
and so forth.
 
Only a minor change to a C program file, and a minor change to the makefile
(makefile_pc.inc.in) were needed to get code to compile.
 
Makefile excerpt:
 
CC=pgcc
DEFS=-Di686 -DLINUX -DBIT32 -DF90 -DFORTRANUNDERSCORE -DDYNAMIC
...
DBCFLAGS= -g -DDEBUG-1 $(DEFS)
...
 
FC    = pgf90
...
 
FFLAGS = $(INC) -g
..
FIXED=-Mfixed
FREE=-Mfree
..
CPP = pgf90 -E
...
MACHTYPE = pc
 
(other lines omitted here).
 
No changes were made to any source code file, save the file "cio.c" --
modification made in bold
#if defined (SGI) || ... || define (LINUX)
#define copen  copen_
 ....
(other lines omitted here)
 
The above makefile was used when compiling the executable "gribprint.exe",
which I used as a test to see if I could read a (valid) GRIB file.
 
gribprint -V    <gribfile>              (GFS data, downloaded from FSL,
verified elsewhere)
 
Sample output:
