that's precisely why I want to port rik to objc1.

Making Objective-C 2 work on PowerPC is almost certainly less effort than porting a codebase to an old dialect and maintaining a less maintainable fork. If you're happy with the slow message send paths (no objc_msgSend, just the old objc_msg_lookup then call the resulting IMP) and you're not using imp_implementationWithBlock then it should all work already, modulo build system issues.

I'd certainly be happy with it. The last time I tried (over a year from now), the problem was a linker issue I could not resolve in Debian Jessie. And it was a hassle. I don't have the knowledge to deal with this kind of issues.

I'm eager to upgrade it to Debian unstable because there is a work in progress to have it easily installable on macs.

I have here a powerbook G4 with a stable debian jessie, a good working browser (Articfox) and a working gcc gnustep install which is my day-to-day desktop. It works like a charm, really.

I may try another time someday to build libobjc2 but not on this machine. But the more I wait, the more difficult to get are the dependancies (clang for instance, is constantly moving from a version to another). I'm not sure I would try with the new api of libobjc2 because I really don't want to build clang by myself. For now, objc1 does seem to be a sustainable effort to me while objc2 doesn't, sorry.

Cheers, Bertrand
