3.3 Building on 64 Bit Platforms
The compiler options for SunOS, Irix, and AIX are listed below. The
zlib and HDF5 libraries must also be built with 64-bit options.
- 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.
- Set the -64 option in all compilers.
- Use the -xarch=v9 or -m64 flag on all compilers for Sparc, or -m64 on
