For older SDKs, he will also need to use the "-iwithsysroot" option to select headers for the compilation and symbol sets for the linkages so that they don't depend on changes after that version shipped (this would be automatic with the SDK selection, if he were using XCode, which he isn't, which is why I pointed him at the gcc man page). The MacOSX10.3.9.sdk is not installed for recent Leopard or XCode distributions. The first version of the SDK that would work for both Intel and PPC was shipped in Inca and was the MacOSX10.4u.sdk (the "u" stands for "universal". When we shipped Intel, we change the version of the compiler required; you aren't going to be able to build for PPC and Intel with the same compiler version if you are building PPC that old. Given that Panther shipped in 2003, it's probably time to give up on supporting 10.3; 10.3.9 barely has a chance to run binaries created with the 10.4u SDK, as we explicitly retrofited compatibility stubs for both some of the $UNIX2003, and all of the 64 vs. 32 bit "long double" for PPC into the libSystem in 10.3.9 software update. 10.3.8 and before have little/no chance of running them, which was the primary reason for the update. If they're is willing to do that, then they will want the following flags: (this assumes that they did not take advantage of the ability of the new XCode to install itself into a non-standard location). If they're not willing to do that, then the only alternative is to build separate PPC (on a 10.3.9 system) and Intel binaries, and lipo them together into a universal binary, which is not something I'm going to recommend by documenting how to do.

I'd like to convert that information to printable strings so I know the name of the function and the offset from the start of the function (or, better yet, the line number, but I'll live with the offset). Is there a simple way of doing this lookup? I looked into nlist(), and it appears to have some of the information I need, but I don't see how to get the function names from the information it gives me. The debugger, gdb, also has multiple modes in which it operates, two of which can be programmatically controlled (to permit things like GUIs that still use gdb internally). You could open the binary with gdb in one of these modes and interactively query gdb for the information. If the intention is from within the instrumentation, dladdr will be your best bet. If the intention is post-mortem analysys, your best bet is going to be atos. If the intention is interactive external analysis (for example, if you are recording non-statistical profiling arcs in shared memory and analyzing them on the fly), your best bet is going to be gdb.
