[netCDF #OXF-630724]: issue when compiling

Hi Thom,

It appears that when trying to link your executable, the linker is unable to 
find the various _nc_ functions, such as those referenced below.  This 
immediately suggests that the linker is not trying to link against libnetcdf, 
typically specificed with -lnetcdf.  If it were trying to link but unable to 
find the library, I would expect to see an error indicative of a 'file not 
found'-type situation.  

Are you passing -lnetcdf to your compiler?  If so, can you provide the command 
you are using to compile your test program? I will take a look and try to sort 
out what is going on.

Thanks!
