I find it absolutely appalling on a modern OS that I should have to write a 3rd PPC process and launch it just to get the API to behave as documented.

Launch a dummy child process that only contains ppc code, then wait for that process to exit. The dummy simply does exit(0). This ensures that Rosetta is running if it's on an Intel CPU, or it will have simply burned a fork/exec on a PPC CPU. Either way, you should then be able to launch further executables with little or no delay. "Priming the pump", so to speak. You may not even need to write any dummy code on 10.5+. The /usr/bin/arch command can select a specific architecture (ppc in this case), and the /usr/bin/true command already performs an exit(0). E.g.: /usr/bin/arch -ppc /usr/bin/true There may be other ways to improve this beyond BF&I, such as testing the non-dummy executable before launching it, to see whether it even needs the dummy to load Rosetta first. -- GG _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
