Hi Ana,
The makefile included for building ccm2nc on the SGI uses the -64 flag only
because that's how our netCDF library was built at NCAR. But the bottom
line is that ccm2nc and the netCDF library need to be built the same way.
So either build ccm2nc using the -n32 flag (or -32 for older SGIs) or build
the netCDF library using the -64 flag. If the "-64" binary is not
available from unidata then get the source and build it locally. Also, the
specification of the -mipsn flag depends on the hardware you are using.
The "-64 -mips4" flags work on an R10000.
