Re: Problem running PyNIO 1.3.0b1

Hi Deidre,

The undefined symbol is from the HDF-EOS library. The version of
libnio.a (in $NCARG_ROOT/lib) that you are
linking with was built with support for HDF-EOS.
For now the only fix is either to build the HDF-EOS libraries
yourself or else to build NCL from source without
support for HDF-EOS. Note this is HDF-EOS version 2, which is based
on HDF4.
This will be fixed with the next release of PyNIO, which will include
all the files
necessary to build libnio.a without any dependence on NCL or other
NCARG software. You will be able to
optionally specify support for HDF-EOS and GRIB 2.
Actually I expect to have this capability enabled by next week. If
you would like a pre-release version let
me know.
