Not quite sure what you are asking.

Most compilers default to 32-bit binaries.

Many people (including me) also compile it for 64 bit architectures.

In all cases, the same data file is produced. If you have a program,
like a model, and it is compiled for 64-bit, and you want to call a
netcdf function, you need a 64-bit version of the netcdf library.

If you have a 32-bit program, you need a 32-bit netcdf library.

Some people even have both on the same machine, in different places. 

Does any of this answer your question?
