6.1 Universal binaries

LispWorks (32-bit) for Macintosh is a universal binary, containing both PowerPC and Intel architectures. To deliver a universal binary application from LispWorks (32-bit) for Macintosh, you will need an Intel-based Macintosh computer running Mac OS X version 10.4, 10.5 or 10.6. You can specify a universal binary build in the Application Builder tool (see the LispWorks IDE User Guide ) or call save-universal-from-script directly (see the LispWorks User Guide and Reference Manual ).

Please note that LispWorks cannot build universal binaries on Mac OS X 10.7 (or any PowerPC binary) because Apple no longer support Rosetta on that version of the operating system.

LispWorks (64-bit) for Macintosh is also a universal binary, containing both PowerPC and Intel architectures. To create a universal binary application from LispWorks (64-bit) for Macintosh, you will need to deliver separately on both a PowerPC Macintosh and an Intel-based Macintosh computer. Contact Lisp Support if you need advice on creating a 64-bit universal binary after that.
