We've brought one up and haven't had any problems yet. Does anyone forsee any problems? I don't know what you want, exactly, but in the public interest: 1.0 executables run fine under 2.0, so long as they weren't excessive in going underneath the OS. Example of excessive? XNeXT. 1.0 programs will, in general, compile under 2.0 fairly well. A couple changes have been made in include files, which will neccessitate changes in your code, but that isn't too hard. The only problem I've had is that the libtext.a library is gone. You can get it from NeXT, I think, but I just copied a 1.0 version, and it seems to work fine. 2.0 programs will not run under 1.0. This is because too much of the libraries have changed. More importantly: 2.0 .nib files are not compatible with 1.0. I found this out the hard way. 1.0 .nib files work fine under 2.0, but once saved from InterfaceBuilder in 2.0, you cannot read them from InterfaceBuilder in 1.0. This extends further than just the added objects in 2.0. A raw .nib file without anything amazing does not move back to 1.0, either. Of course, it is hard to see why one would go back to 1.0 once at 2.0, but I'm sure reasons will show up. I've not seen anything nearly bad enough to warrent moving back yet, though . . . -- scott hess scott@gac.edu Independent NeXT Developer GAC Undergrad "Tried anarchy, once.
