CodeWarrior is DEAD No matter what we feel about it (or how much we have invested in it), there is no bringing it back. XCode et al. is the ONLY way (currently and for the foreseable future) to build native MacTel binaries (this has been hammered pretty clearly to us by Apple). The crux of the problem (at least the main problem), indeed might be that Poser 6 still relies on CFM code. I do not know that, as I have not investigated seriously that problem, and do not have any insider information (since I am not an insider :-) ). Tcl/Tk does indeed work on MacOS X, it is simply not CFM-abiding, and thus not callable from CFM code (if that's what Poser 6 is, a very reasonable guess), unless one uses some arcane trickery (I do not recall if what had been developped was for calling CFM from MachO or the other way around; I do remember it was first said to be impossible, so someone did go and prove everybody else wrong; I was on MacOS 9 at the time so did not pay much attention to it, unfortunately). No such trickery will be available for MacTel software (unless again someone proves Apple and everbody wrong ;-) ). Perhaps we could sum up the present situation under MacOS X as: Poser 6 relies on end-of-life, or beyond, tools to extend, Poser 7 had better be ported to XCode & al. to have any chance of survival. Let us just hope that the PTB are aware of this. Hubert Holin
