Package: grads
Version: 2.0.a9-4
Severity: important
Hi, when I try to use grads in a OPeNDAP repository the following error
occurs:
$ grads -l
ga-> sdfopen http://goldsmr3.sci.gsfc.nasa.gov/dods/MAIMCPASM
Scanning self-describing file:

netcdf: 5 is not a valid cdfid
Segmentation fault
>From [1], this is because there is a conflict in function names of
netcdf and hdf4. I rebuild grads package with libhdf4-alt-dev and work
fine, but is needed adjust configure.ac and m4/hdf4.m4 (patch attached).
With this change the hdf4-netcdf patch can be removed.
