I've been using NETCDF compression since V3.5, when it first started. I have the variable set to NETCDF4=1. I use NETCDF version 4.4.1.1. When I run the configure script, I get :
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
*****************************************************************************
This build of WRF will use classic (non-compressed) NETCDF format
*****************************************************************************
It then compiles just fine. (Intel compiler and Intel MPI).
nothing has changed in my setup from V3.9.1.1 to V4. Is there something I'm missing? Is it really going to use compression (just a false warning), or is there something else I have to do in V4?
Thanks!
