Hi Folks, Has anyone managed this? Bytecode seems fine, native not so.I've tried just ./configure and ./configure -cc "gcc -m64" with the source bzip of 3.11.1 as suggested in INSTALL. Both compile fine, but give:feast:trunk john$ ocamlopt -c a.ml feast:trunk john$ ocamlopt -o a a.cmx ld: warning: in libasmrun.a, file is not of required architecture Undefined symbols: "_caml_ml_set_binary_mode", referenced from: .L139 in stdlib.a(pervasives.o) .L157 in stdlib.a(pervasives.o) _camlPervasives__102 in stdlib.a(pervasives.o) _camlPervasives__102 in stdlib.a(pervasives.o) ...

I just installed Snow Leopard in my laptop and the x86_64 ocaml appears to work fine. I noticed that in your configure log the gcc compiler is still listed at the end as 'gcc', while in mine it is 'gcc -m64'. Perhaps you need to cleanup with 'make distclean' and reconfigure before compiling the x86_64 target?
Another question: Can I build a version of OCaml from these sources which isn't 64-bit so I can build code which will run on 10.5/10.4?
Previous versions of gcc in Mac OS X allowed you to pass the -mmacosx- version-min=10.4 option to target the minimum API that you wanted to support. I suppose this still works with the gcc 4.2.1 included in XCode 3.2, but haven't tried it yet.
