[netCDF #EXA-981548]: a question with udunits.h

Hi Jie,

It's the C include file for an optional Unidata software package that handles 
of measurement.  Apparently it's not optional for GrADS, which requires udunits 
installed first.  You can install udunits when you build and install netCDF by 
the "--with-udunits" option to the netCDF configure script, then "make check" 
"make install".  This will install udunits.h in /usr/local/include by default, 
wherever you specify if you use the "--prefix=..." option to the configure 

Alternatively, you can get just the udunits2 source from Unidata and install it
independently of netCDF, allowing you to use the existing netCDF installation.
