OK, apologies everyone. When I looked at the warning items again, |
see that xcode was trying to build against the debug version of my
framework!
The thing is, I have no idea why! Every reference to the framework
in my project is to the release version, so I can't figure out why
xcode would do this.
Still, I started a new test app in the end, and everything seems to
work fine. Sorry for wasting your time!
Mike.

The framework happily compiles in release mode and lipo reports
that the framework is universal.
So, I then create a new application and add my framework to it. In
development mode, this compiles fine. However, when I switch to
release mode, I get this error:

As far as I can make out, he compiler is saying that my framework
does not support Intel. Indeed, if I modify my release target to
only build for PPC, everything works fine.
So, the only reason I could see for my framework to not be
Universal, was that I had linked to /usr/lib/libz.dylib
I checked, and indeed this is PPC only. So instead I link to the
universal version in the 10.4uSDK. Same thing again. And if I
don't link to either, but add the -lz compiler option, same again.
So, um, does anyone know what my problem might be?
