Siji and Michael and ncarg-talk folks,

With regard to building NCAR Graphics on an AMD Opteron 64 host running
Linux, there's a bit of configuration work that you'll need to do in order
to build properly/cleanly. Let's assume:

$NCARG_ROOT_SRC = /dir/where/you/untarred/ncarg/source/code

Step-by-step:

1. edit $NCARG_ROOT_SRC/config/LINUX.pgi
change: #define ArchRecLibSearch -L/usr/X11R6/lib
to: #define ArchRecLibSearch -L/usr/X11R6/lib64

change: FC = $(F77)
to: FC = $(F90)

2. cp $NCARG_ROOT_SRC/LINUX.pgi $NCARG_ROOT_SRC/LINUX

3. Setting these environment variables can be useful:

      CC=pgcc
      CPPFLAGS=-DNDEBUG -DpgiFortran
      CFLAGS=-O -Msignextend -Mreentrant -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE
      FC=pgf90
      F77=pgf77
      F90=pgf90
      FFLAGS=-O -w -Msignextend -Mreentrant -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE
      CXX=pgCC
      LIBS=-L/opt/pgi/linux86-64/5.1/lib -lpgc -lpgf90

(note: -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE are not strictly
required but do not hurt)

4. Run 'Configure' and then 'make'

Alternately, I've created a binary NCAR Graphics distribution for AMD
Opteron 64 hosts, which is available via anonymous ftp:

  ftp.ucar.edu
  login: anonymous
  passwd: your email address

cd to 'ncl'
file is: ncarg-4.4.0-x86_64.tar.gz

Please let me know of any questions.

-Rick.
