[MINC-development] me, I'm stumped

[John G. Sled]

Hi Jason,

Under 32-bit linux I was able to get commands such as the following to 
work 

rawtominc -short /tmp/junk.mnc 2048 1024 1024 < /dev/zero

Under linux I had to build minc and netcdf with the options

 -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64

Is there something similar for IRIX?

John
