Currently the 1.9b1 compilers that ship in the "Prerelease" folder (read:
unsupported!) on CW Pro1 do support Objective C. This is both the 68K and
However, Metrowerks has only provided a RUNTIME environment for 68K. So
you can compile for PPC, just can't run (and probably can't really link
either). This is due to the fact the mini-runtime contains some 68K
At this time Metrowerks isn't looking into providing robust support for
Objective C on the current Mac OS as there is a great deal of runtime
support that would be necessary to implement; this is something that
Rhapsody will give us for free (as it's all built into the OS). It's just
not worth it for Metrowerks right now to reinvent the wheel. This might
change in the future, but I'm not making any promises nor guarentees.
I do believe some third party has implemented a PPC-native runtime (just
took our stuff and recoded the 68K into PPC), but it's not Metrowerks
supported and I don't know the contact information for the author or URL.
Hopefully someone reading the newsgroups will know.
Anyways, take a look through the Objective C examples that are also
provided, and read the release notes and documentation included in those
archives. That should explain everything.
