libpq.a in a universal binary

Hi,

The short summary that I use for .a files is:

Build on PPC
Build on Intel

On either run

lipo -create lib/libpq.a ../ppc/lib/libpq.a ../intel/lib/libpq.a

Before a

file libpq.a

shows

libpq.a: current ar archive

After lipo it shows:

libpq.a: Mach-O fat file with 2 architectures
libpq.a (for architecture ppc): current ar archive
libpq.a (for architecture i386): current ar archive random library

There is a nice Apple tech note on this

http://developer.apple.com/technotes/tn2005/tn2137.html

that talks about Universal Binaries.

It's possible that you might be able to do this all in one go since
the Apple compiler can support generating both intel and ppc output in
the same fat file. But, if you can't, then the above technique works
just fine.

cheers

If brute force doesn't work, you're not using enough of it.
