It turns out that if you would like to use the opengrads supplibs-2.1.0
available from


http://sourceforge.net/project/showfiles.php?group_id=161773&package_id=241681&release_id=661716

to build grads-2.0.a6 from sources you need a little configure magic.
First, untar the supplibs binary and make a symlink such that supplibs/ is
parallel to the grads sources:

  supplibs -> ../supplibs-2.1.0/x86_64.....   (or whatever other
architecture you have)
  grads-2.0.a6/

Here is how I built it on x86_64:

% cd grads-2.0.a6
% export CPPFLAGS -I../../supplibs/include/netcdf
% ./configure --without-gui

This will give you:

Then to build gradsdap you need to help it along:

% cd src/
% make gradsdap LIBS="-lnetcdf -lnc-dap -ldapclient -ldap -lhdf5_hl -lhdf5
-lcurl -lxml2 -lz -lpthread"
% make utils

This will create "gradsdap" linked against  NetCDF-4 so it will be have
support for all formats, including grib2, opendap, netcdf-3/4, hdf-4, just
like the most recent opengrads builds:

Don't bother building "grads" because NetCDF-4 has OPeNDAP integrated in
(you would get the same executable after fixing the Makefile); just make a
symlink, grads -> gradsdap. Keep in mind that  this build will *not* have
the opengrads extensions enabled. It will be about a week untill I have a
chance to patch it.

Caveat: it has been reported that this opendap library has a problem reading
some non-gds opendap datasets when the coordinate variables (like time) are
int  (only on 64 bit Linux AFAIK).
