[Numpy-discussion] pyhdf / was: Request for porting pycdf to NumPy

[Christian Marquardt]

As we are at it,

Andre Gosselin (the guy who wrote pycdf) also wrote an interface to HDF4
(not 5) named pyhdf. I'm using that with numpy as well (patch attached),
but I haven't tested it much - little more than just running the examples,
really (which appear to be ok). Maybe it's useful...

In pyhdf, the author didn't support different array interfaces; so the
attached patch just modifes the existing source code and moves it over
to numpy. I've also attached a "install script" which makes use of the
particular lacotion of the HDF4 libraries (in $PREFIX/lib) and header
files (in $PREFIX/include/hdf), so it it almost certainly needs to be
adapted to the location of the actual HDF libraries and headers.

Regards,

  Christian.
