I don't think OSX's dynamic linking supports runtime overrides the way ELF with weak symbols does. Actually, it looks like it does to some extent, but only if the programs you're linking into use flat namespaces; Leopard and Snow Leopard default to 2-level namespaces. See the "-flat_namespace" and "-force_flat_namespace" options to ld(1). Looks to me like a program has to be linked with the latter option to support it. That's going to severely restrict what you can use it with. -- brandon s allbery allber...@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
