I confirm that my 10.4.4 iBook-G4 has nothing in the /usr/lib
hierarchy that is Universal, but my 10.4.4 Intel iMac has all
Universal dylibs in /usr/lib. Both have the same version (2.2.1) of
Developer Tools installed.
10.4.4 != 10.4.4.
Anyone know what it takes to install 10.4.4 in a manner that installs
the Universal libs? BSD SDK perhaps?
Lacking that, I suspect that weak-linking libz will allow you to
complete the build.

Hi all,
Sometimes ago I emailed asking about decompressing file and I was told
to use zlib. I have used it successfully so far for my project. But
there is problem when I try to compile my project for intel-based
machine. fyi, I am working on powerpc at the moment, using xcode 2.2,
and the project itself is mainly using objective-c language. I need to
compile this project to be universal-binary-enabled as the clients
machine require so.
When I set the architecture to both intel and ppc, I stumble into
errors where zlib's functions such as inflate, inflateEnd, etc.. get
Undefined Symbol error message.
So the command line such as:
int err=inflateInit_(&m_ZRec, zlib_version, sizeof (m_ZRec));
which would cause no error when compiling for ppc, is know becoming an
error. This command line is written in an objective c class that
already include zlib.h. I wonder what could the problem be. Thanks in
advance for the pointers on this problem.
Regards
David
