Re: trouble building 4.4.2 with hdf

Indeed, a bit older than current, which is NCAR Graphics v4.4.2:

In the time since your current version of NCAR Graphics was
installed, some changes to the expected supporting directory
structure have been made. As you note, the NCAR Graphics build
process is expecting to find HDF include files in a
directory structure of the form

     .../hdf/{hdf.h, dfgr.h, df.h}

This is noted on the NCAR Graphics Installation Notes web page for
installing from source code:

     http://www.ncarg.ucar.edu/ng/installsrc.html

There you'll find a note about HDF and what NCAR Graphics expects in
terms of version, installation, and such:

     http://www.ncarg.ucar.edu/ng/installsrc.html#GetHDF

You don't say what version of HDF you're using; we suggest HDF
4.2r1. When installing HDF, you may specify the location
of installed header files at configuration time.

Please contact me or the group if you have further questions.
