Description

The function save-universal-from-script provides a convenient way to create a universal binary on an Intel Macintosh, using a script designed for saving a mono-architecture image.

The script-name is the name of a Common Lisp build script for saving or delivering an image, as would be used to create a mono-architecture image. It should load the application and then call either deliver or save-image as appropriate.

The function save-universal-from-script runs the current LispWorks image in two subprocesses, once for the PowerPC architecture (under Rosetta) and once for the native Intel architecture, passing -build script-name on the command line. The script is evaluated as normal, except that the filename that is passed to any call to save-image or deliver is ignored and a temporary filename is used instead. If these two subprocesses are successful, then the temporary images are combined to make a universal binary target-name in the same way as create-universal-binary .

The command line arguments of the images run by the subprocesses will include the command line arguments that were passed to the current image. In addition, various undocumented command line arguments will be prepended, which control how deliver or save-image work in the script.

Any output generated by the subprocesses is written to output-stream . If this is nil , then the output is discarded. If this is t (the default), then the output is written to the standard output.

Note: The function save-universal-from-script can only be called from a LispWorks for Macintosh image that is itself a universal binary, such as the distributed image.

Example

Suppose the file my-build-script.lisp contains

(load-all-patches)

(load "my-application-defsys")

(compile-system 'my-application-system :load t)

(deliver 'my-application-function "my-application" 5)

Then, the following call creates a universal binary my-application using this script:

(save-universal-from-script "my-application"

                            "my-build-script.lisp")
