Function

Summary

Creates a universal binary from two mono-architecture LispWorks images.

Package

hcl

Signature

create-universal-binary target-image src-image1 src-image2 => target-image

Arguments

target-image

A pathname designator.

src-image1

A pathname designator.

src-image2

A pathname designator.

Values

target-image

A pathname designator.

Description

This function is intended for advanced use. See the function save-universal-from-script for a simpler way to create a universal binary.

The function create-universal-binary writes a universal binary to the file target-image from the saved image files src-image1 and src-image2 . The value of target-image is returned.

The source images src-image1 and src-image2 must both be LispWorks for Macintosh mono-architecture ("thin") images and one should be for the Intel architecture and the other for the PowerPC architecture (the order is immaterial). For example, they could have been created by save-image or deliver.

Notes

1. The function create-universal-binary checks that src-image1 and src-image2 are LispWorks images of different architectures, but it does not check how they were saved or how similar they are. You need to ensure that both images contain the same functionality.
2. The function create-universal-binary can only be called from a LispWorks for Macintosh image that is itself a universal binary, such as the distributed image.

Example

Suppose that you have saved two images, my-application-intel and my-application-powerpc , which contains the same application code loaded on an Intel Macintosh and a PowerPC Macintosh. The following command will combine them into a universal binary my-application that will run on both kinds of Macintosh:

(create-universal-binary "my-application"

                         "my-application-intel"

                         "my-application-powerpc")
