OSX 10.4 doesn't provide 64-bit versions of GUI libraries.  (It actually
doesn't provide 64-bit versions of the CHUD libraries either, as of
the last version of CHUD that I checked; the chud subdirectory of
ccl/darwin-headers64 just contains a script that can be used to create
headers from CHUD interfaces whenever a CHUD release with 64-bit versions
of its libraries appears.)  You simply can't write 64-bit
programs that use Cocoa or Carbon or other Apple GUI frameworks on
OSX 10.4 (in C, OpenMCL, or otherwise.)

64-bit versions of Cocoa, Carbon etc are an announced feature of OSX
10.5.  It seems reasonable to assume that 64-bit C/ObjC headers will
also be provided with the development tools for 10.5, and that running
those headers through OpenMCL's interface translator (see


will produce interfaces that OpenMCL can use.

[Probably a separate issue:

It also seems reasonable to assume that some people will want to use
prerelease versions of Leopard (OSX 10.5) with OpenMCL, and it would
be in those users' interests (and OpenMCL's) if they were able to use
Carbon and Cocoa from OpenMCL under those Leopard prereleases.  People
who have access to prerelease versions of Leopard have that access
under non-disclosure, and (being paranoid about it) it's not clear
whether distributing Leopard interfaces would violate the terms of
some NDA.  (If it actually does, that'd be pretty stupid, but it'd
probably be equally stupid to assume that it doesn't only to be
told otherwise by an Apple lawyer.)]
