Hi Jim, First, Tom Rink is the real authority on VisAD's HDF-EOS adapter so Tom please correct me if I get any of this wrong. There are three layers of native code for VisAD's HDF-EOS adapter. 1. The basic HDF4.1r1 code from NCSA at: ftp://ftp.ncsa.uiuc.edu/HDF/HDF_Current 2. The HDF-EOS code from NASA at: http://ulabibm.gsfc.nasa.gov/hdfeos/hdf.html#4 3. The VisAD JNI links, written by Tom, and in the visad/data/hdfeos/hdfeosc directory of the VisAD source distribution. The HDF home page at http://hdf.ncsa.uiuc.edu/ does not list AIX among supported platforms, but does list tools that run on AIX and access HDF. It is hard to believe that the basic HDF libraries have not been ported to AIX. The HDF-EOS Product Description lists AIX as a supported platform, under AIX 4.2, with IBM C 3.1.4.0 and IBM FORTRAN 3.2.5 (since this uses the basic HDF library, it suggests that the basic library runs on AIX). The VisAD native code for HDF-EOS has not been tested on AIX. For one thing, VisAD requires Java 2 which is not yet ported to AIX. There is a pure Java interface to HDF (from NCSA), so hopefully NASA will produce a pure Java version of their HDF-EOS library and then VisAD can go pure Java for HDF-EOS (as it does for netCDF and FITS).
