NetCDF users note:
This installation of NetCDF supports large file support. To DISABLE large file
support in NetCDF, set the environment variable WRFIO_NCD_NO_LARGE_FILE_SUPPORT
to 1 and run configure again. Set to any other value to avoid this message.
Testing for NetCDF, C and Fortran compiler
This installation of NetCDF is 64-bit
C compiler is 64-bit
Fortran compiler is 64-bit
It will build in 64-bit
standard location of RPC
*****************************************************************************
This build of WRF will use classic (non-compressed) NETCDF format
