Using Command-Line Options

You can use the following command line options to specify a compilation mode:

If you specify the -n32 option to the compiler, the system compiles the source files to n32-bit objects.
If you specify the -64 option on the command line, the system compiles the source files to 64-bit objects.
If you specify the -32 option to the compiler, the system compiles the source files to 32-bit objects.
