Hi Will,

That looks better:

Hi Will,  That looks better:

xena.cary$ cd hdf5-1.6.5/include
xena.cary$ grep -i parallel H5pubconf.h
/* Define if we have parallel support */
/* #undef H5_HAVE_PARALLEL */
xena.cary$ cd ../hdf5-1.8.2-ser/include
-bash: cd: ../hdf5-1.8.2-ser/include: No such file or directory
xena.cary$ cd ../../hdf5-1.8.2-ser/include
xena.cary$ grep -i parallel H5pubconf.h
/* Define if we have parallel support */
/* #undef H5_HAVE_PARALLEL */
xena.cary$ cd ../../hdf5-1.8.2-par/include
xena.cary$ grep -i parallel H5pubconf.h
/* Define if we have parallel support */
#define H5_HAVE_PARALLEL 1

available back through 1.6.5.

I was probably doing something for much older versions, as I now
see the full fragment:

if test $ac_cv_have_hdf5 = yes; then
  if test -f $HDF5_INCDIR/H5config.h; then
    hdf5par=`grep "HAVE_PARALLEL 1" $HDF5_INCDIR/H5config.h`
  elif test -f $HDF5_INCDIR/H5pubconf.h; then
    hdf5par=`grep "HAVE_PARALLEL 1" $HDF5_INCDIR/H5pubconf.h`
  fi
fi

which agrees with yours.

Best.....John
