I have an XCode project which uses some assembler code for
mathematical efficiency. I wonder how to build a universal binary.
If I simply use the "Architectures" target setting and choose both,
the compiler blows up on one branch of the compile because it sees
incompatible assembler code.
This may be a very basic question, but do you have assembler code for
both architectures? If not, do you have C code for the other
architecture? You can't assemble ppc code for intel, nor can you do
the reverse.
Is this assembler code inline, or it is separate assembler files? If
it is the former, you can wrap it with architecture macros. If it is
the latter, then you are probably going to have to play games with
targets and libraries.
I can imagine some ways to handle this:
1) is there a way to make one universal target from two independent
targets, or
2) is there a compiler variable that I could test to include the
relevant assembler code and exclude the irrelevant, or
3) is there some other way to do this?
I see nothing in the XCode documents that deals with this, though I
may have overlooked it.
thanks,
David
