3.3 Building on 64 Bit Platforms
Some platforms support special options to build in 64-bit mode.
NetCDF 3.6.2 has been tested as 64-bit builds on SunOS,
Irix, and AIX. The options needed to build in 64-bit mode on these
platforms are described here, and can be turned on by providing the
–enable-64bit flag to configure.
AIX- Set -q64 option in all compilers, and set NMFLAGS to -X64, and ARFLAGS
to '-X64 cru'. Alternatively, set environment variable OBJECT_MODE to
64 before running configure.
IRIX- Set the -64 option in all compilers.
SunOS- Use the -xarch=v9 flag on all compilers. This is not supported on the
x86 platform.
