Apple releases Xcode 2.4 with 64-bit support

Apple has released Xcode 2.4, an update to its set of developer tools for Mac OS X. According to the release notes: “The tools now support development of 64-bit Mach-O binaries for Intel with the -arch x86_64 flag. The design of the relocation entries for the x86_64 architecture does not make it possible to strip local symbols from relocable object files. As such the feature of running strip(1) with the -x option to limit the symbols to just the exported symbols is not available on the x86_64 architecture. And the strip(1) -x option for an x86_64 object file does nothing.”
