When I run this make file resulting from the configure script I get told that: /usr/libexec/gcc/i686-apple-darwin8/4.0.1/ld: warning fat file: /usr/ lib/libSystem.dylib does not contain an architecture that matches the specified -arch flag: i386 (file ignored) Is it not possible to build a universal binary on a PowerPC based system? If it is using the system library instead of the SDK library, you have improperly specified your arguments. Most likely you have installed new tools on an old system which predates Intel support, and failed to use the appropriate argument to the "-syslibroot" directive to the linker. PS: This would be an unsupported configuration for your development environment, I believe. This email sent to site_archiver@lists.apple.com
