MacOSX11.sdk

[Nathaniel W Griswold]

Ah, ok. Thanks. Ya i couldn't find that email when i just googled for it again, it's just what i remember finding when i ran into the problem and apple had already switched over to doing the symlink thing.

Thanks

Nate

The SDKs seem to be backwards compatible since apple only includes the very newest SDK in each new release of the command line tools. The correct answer seems to be to use the symlink unless i'm missing something.

I guess Apple must have been given enough feedback that this more rapidly evolving sdk version was problematic and thus has started adding the major version only link as a consequence. Assuming it is here to stay then yes this is really now what we should be using I would say.

If MacPorts used MacOSX11.sdk when available instead of the more-specific version number, it would reduce some of the problems we have from baked-in SDK paths in some ports. Would be nice if we could fit that change into the MacPorts 2.7.0 release.
