Setting an Environment Variable
You can set an environment variable to specify the compilation mode to use. To set up your environment for n32-bit compilation, type:
setenv SGI_ABI -n32
To set up your environment for 64-bit compilation, type:
setenv SGI_ABI -64
To set up your environment for 32-bit compilation, type:
setenv SGI_ABI -32
If you don't specify -32, -n32, or -64 on the command line, or don't set an environment variable, the system determines the compilation mode to use.
