That's right. The source package included the latest version 3 API in
contrib/netcdf/v4/libsrc
and version 4 API in
contrib/netcdf/v4/libsrc4
The version 4 API requires HDF5, and the latest exodus requires version 4 for
full feature support.
When HDF5 is absent we fall back to building the libsrc version 3 only API, but
from the new 'v4' source tree (sorry for the confusion!!) and then tell Exodus
to turn off the new features, c.f. exodus.m4:
# no HDF5 &/or no NETCDF4
EXODUS_NOT_NETCDF4_FLAG=""
if (test "x$enablehdf5" = "xno" -o "x$netcdfversion" = "x3"); then
EXODUS_NOT_NETCDF4_FLAG="-DNOT_NETCDF4"
AC_MSG_RESULT([defining -DNOT_NETCDF4 for our Exodus build])
fi
