When I do a Get Info on the application bundle of my current project, I see ...

This raises a number of questions.

1. What would happen if my application were run on an Intel machine?
(I ask just because I'm curious.)

Dunno; tar it up and send it to me if you want. I'll try it out.

2. In this case, the Unix Executable File comes with source code. Is it possible to recompile to obtain a "Unix Executable File (Universal)"?
(I ask because I've never used Xcode. Perhaps it's time I learned.)

I recently had this same question. On Saturday 2 September 2006 06:16:55 CDT, djl replied to my query by saying:


At a guess I'd say that if you have the source code then you'd either need to:-

Compile the source code via the command line for and on both a PPC and an Intel Mac - then use code in your project to determine which processor is running. Something along the lines of:-

set cpuType to CPU type of (system info)
if cpuType contains "PowerPC" then
	set theCpu to "PowerPC"
else
	set theCpu to "Intel"
end if
display dialog theCpu



or

Use XCode to generate a Universal Binary. I'm not au fait with doing this but take a look at this document from Apple's site which should point you in the right direction:-

Good luck!
