question

[John Tannahill]

Please keep me posted as to the status of my problem with the
Fortran interface.  I will look at it some more myself, but I
don't have much experience with autoconf, etc.  Maybe the autoconf
stuff is fine and it is just something more basic I am missing?  I
would be happy to send you any diagnostic information you would like.
In fact, I will include here the procedure I used to get the library
installed on seaborg/NERSC (it's a little different than what I
used on frost):

seaborg:
-------

gunzip parallel-netcdf-0.8.4.tar.gz
tar xf parallel-netcdf-0.8.4.tar
cd parallel-netcdf-0.8.4
vi configure.in
   Change:
     UC_PROG_FC
   To:
     UD_PROG_FC
setenv CC xlc
setenv FC xlf
module load gnu
autoconf
vi configure
   Comment out the following lines in configure:
     ###if { (eval echo "$as_me:$LINENO: \"$ac_compile\"") >&5
     ###  (eval $ac_compile) 2>&5
     ###  ac_status=$?
     ###  echo "$as_me:$LINENO: \$? = $ac_status" >&5
     ###  (exit $ac_status); } &&
     ###         { ac_try='test -s conftest.$ac_objext'
     ###  { (eval echo "$as_me:$LINENO: \"$ac_try\"") >&5
     ###  (eval $ac_try) 2>&5
     ###  ac_status=$?
     ###  echo "$as_me:$LINENO: \$? = $ac_status" >&5
     ###  (exit $ac_status); }; }; then
     ###  echo "$as_me:$LINENO: result: yes" >&5
     ###echo "${ECHO_T}yes" >&6
     ###else
     ###  echo "$as_me: failed program was:" >&5
     ###cat conftest.$ac_ext >&5
     ###{ { echo "$as_me:$LINENO: error: mpi implementation does not support ...
     ###echo "$as_me: error: mpi implementation does not support MPI-IO" >&2;}
     ###   { (exit 1); exit 1; }; }

     ###fi
./configure --prefix=/usr/common/homes/j/jrt/Pnc/parallel-netcdf-0.8.4
vi macros.make
   Change:
     CC  = xlc
     CXX = xlC_r
     FC  = xlf
   To:
     CC  = mpcc_r
     CXX = mpCC_r
     FC  = mpxlf_r
make
make install
