[netCDF #PWT-334145]: Error while compiling wgrib2

Hi Frank,

The only similar error I've seen was related to some over-aggressive
compiler optimization flags that didn't preserve standard behavior
when dealing with floating point numbers representing Nan's and
infinities:

If you really need this version built from source, could you 
please send us the config.log generated by the configure script 
when building?

The netCDF-3.6.3 version (from 2008) is so old that we can't easily
support it anymore.  Have you considered trying to build a newer
version, such as netCDF-4.3.0?  You can specify --disable-netcdf-4
when you build it, if you only need to deal with netCDF-3 data and
functions.

Finally, instead of building from source, you can get a binary netCDF
package already compiled and built from

  http://packages.ubuntu.com/source/lucid/netcdf  (version 3.6.3)

or

  http://packages.ubuntu.com/source/precise/netcdf  (version 4.1.1)

or other Ubuntu package repositiries,
