The uuid_generate family of functions is fine. The content of the LC_UUID load command is primarily intended to tie an executable binary to its matching debug info dSYM bundle unambiguously. Computing some digest of the binary, like an MD5, is also fine. Using an MD5 will add time to your file generation but it does mean that two binaries with the same contents will have the same LC_UUID which may be helpful depending on your build environment. An example of how this can be useful: A Spotlight importer is included in Leopard which indexes the LC_UUIDs of all the dSYMs in its search space. When you run the debugger on an executable, it can do a Spotlight query to find the matching dSYM bundle debug info automatically. This email sent to site_archiver@lists.apple.com
