Automator error and Snow Leopard

Question

In Snow Leopard's Automator, I'm getting an error that says my Automator actions are not Universal, which is incorrect, since they are certainly Universal Binaries.
However, after doing some research, I've found other similar cases, and it seems that this error is misguiding, and that the Automator actions just have not been compiled to be 64-bit yet. From my quick glance in Xcode, however, if I want to make a 32/64-bit UB Action, it is only compatible with Mac OS 10.5 and above. Am I wrong in my assumption? Might it be possible to build appropriate versions of the Automator actions that will work with Mac OS 10.4 through 10.6?

Answer 1

My concern is how feasible is it to get a 32+64-bit and PPC/Intel hybrid Automator Action that can run on Mac OS 10.4 - 10.6.
Apple has this to say about that...

Automator Actions as Universal Binaries
A universal binary is executable code that can run on either PowerPC-based or Intel-based Macintosh computers.
To move a PowerPC-only project to a universal-binary project may require work involving such programming details as endianness, alignment, and calling conventions. The amount of work generally depends on the level of the source code; lower-level source code (for example, the kernel) requires more work than higher-level code (for example, an application based on Carbon).
The need to make an Automator action a universal binary depends on the language used:
■ AppleScript actions are platform-independent and do not require any changes to run on Intel processors.
■ An action that contains Objective-C code, whether a Cocoa-only action or an action that contains a mix of Objective-C and AppleScript, must be built as a universal binary to run correctly on both Intel and PowerPC processors.
