We don't have a system that exactly duplicates what you have, but can
come reasonably close: x86_64 host running SuSE ES v9

This looks OK...

I realize that this is a switch for Intel's Fortran compiler (ifort)
but do not believe it effects anything related to the build of NCAR
Graphics. If you wish this to be a flag to ifort, I suggest using it
in the FcOptions definition in the $NCARG/config/LINUX file, as well as
defining it at the shell level. As an example, here is what I use to
build NCAR Graphics with the Intel compilers:

setenv CC icc
setenv CPPFLAGS '-DNDEBUG -DLINUX -DUSE_STDARG -DHAVE_STDLIB_H
-DHAVE_STRING_H -DHAVE_UNISTD_H -DHAVE_STDARG_H -DUSE_STDARG
-DMALLOC_RET_VOID'
setenv CFLAGS '-O2 -ansi -fPIC'
setenv FC ifort
setenv F77 ifort
setenv FFLAGS '-O2 -integer_size 32 -real_size 32 -fPIC'
setenv CXX icpc
setenv CXXFLAGS '-O2 -ansi -DNDEBUG -DLINUX -DUSE_STDARG
-DHAVE_STDLIB_H -DHAVE_STRING_H -DHAVE_UNISTD_H -DHAVE_STDARG_H
-DUSE_STDARG -DMALLOC_RET_VOID'

setenv LD_LIBRARY_PATH
/coral/local/intel/cce/9.0/lib:/coral/local/intel/fce/9.0/lib:/lib64

This configuration will create a working NCAR Graphics for Intel
compilers.

Do you mean this to be 'icc' -- Intel's C compiler -- or really 'cc'?
I don't know what 'cc' is on your host, but on mine it's a link to gcc.
  And I suspect this is where your problems noted below come from: the
undefined references for 's_copy' and 's_cmp' and other 's_xxxx'
symbols come from the library libg2c.a -- a GNU compiler library.

If you really do want to use 'cc' (and thus, I think, gcc) then you'll
need to change some of your definitions for compiler switches and
flags. I've never tried to mix-and-match gcc and ifort, and the
following is untested. I would start with what's below and go from
there with trial and error.

At the shell level:
setenv CC cc
setenv CPPFLAGS '-DNDEBUG -Df2cFortran'
setenv CFLAGS '-O -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fPIC'
setenv FC ifort
setenv F77 ifort
setenv FFLAGS '-O2 -integer_size 32 -real_size 32 -double_size=64 -fPIC'
setenv CXX icpc
setenv CXXFLAGS '-O2 -ansi -DNDEBUG -DLINUX -DUSE_STDARG
-DHAVE_STDLIB_H -DHAVE_STRING_H -DHAVE_UNISTD_H -DHAVE_STDARG_H
-DUSE_STDARG -DMALLOC_RET_VOID'

setenv LD_LIBRARY_PATH
/coral/local/intel/cce/9.0/lib:/coral/local/intel/fce/9.0/lib:/lib64

and I'd have my $NCARG/config/LINUX file as:

#define StdDefines -DSYSV -D_POSIX_SOURCE -D_XOPEN_SOURCE
-DDWORDSIZE=8 -DByteSwapped
#define Cstatic
#define Cdynamic
#define CppCommand '/usr/bin/cpp -traditional'
#define CCompiler cc
#define FCompiler ifort
#define CtoFLibraries -lg2c -lgcc -lm
#define CcOptions -ansi -fPIC
#define FcOptions -integer_size 32 -real_size 32 -double_size 64
-fPIC -mp
#define COptimizeFlag -O2
#define FOptimizeFlag -O2
#define XToolLibrary -lXt -lSM -lICE
#define BuildShared NO
#define XLibrary -lXpm -lX11 -lXext

#define ArchRecLibSearch -L/usr/X11R6/lib64
#define ArchRecIncSearch -I/usr/X11R6/include

Good luck.
