Yo, all.
My Dad recently acquired a Pismo (which I'd love to trade him my iMac DV
for...but that's another story altogether), and since he hasn't yet
upgraded his RAM (nor has he got 10.1 for us yet...supply problems are
severe, apparently), he runs it in OS 9 most of the time.
I've been taking advantage of this situation to run CodeWarrior a fair
amount. Thanks to Metrowerks' productivity, it has a nice Objective-C
compiler which I've been using happily along with the runtime they
included on the resource disk.
Problem is, objc_msgSend() et al are written in 68K assembler. This isn't
that nice a situation for a PPC. It runs, but still...
So anyhow, I've heard it mentioned in the ObjC-vs-C++ stuff that's been
going on that it's pretty trivial to write an Objective-C runtime. That
being the case, does anybody have one for classic Mac OS that's not
written using 68K assembler?
I've been trying to port some of the asm code from the Darwin project's
objc4, but that's more than just a little out of my league.
The eventual goal with this is to get a basic set of classes running on OS
9 so that I can compile some OS X apps on it. I figure that since
CoreFoundation works on OS 9, I can at least get NSArray, et cetera,
working.
Thanks a million,
