export FC=gfortran
#USE_NETCDF3=0
#USE_NETCDF4=1
#USE_JASPER=1
#USE_OPENJPEG=0
AARCH_specific_flag=--build=aarch64-unknown-linux-gnu

wget https://downloads.unidata.ucar.edu/netcdf-c/4.9.0/netcdf-c-4.9.0.tar.gz
wget https://support.hdfgroup.org/ftp/HDF5/releases/hdf5-1.12/hdf5-1.12.2/src/hdf5-1.12.2.tar.gz

the wgrib2 binary will sit in ./wgrib2/wgrib2
