If you’ve played around with NextStep/OpenStep trying to build a sample app — say, so you can find out how much OS X/the iPhone is like those sweet black machines of yesteryear — you might have an error like this one, when attempting to build a sample app you’ve created:
AppKit.h not found (or any one of the other billion header files that are missing)
This may mean an incomplete installation of the Developer tools. Here’s what to do:
- From the Developer CD, open the NextCD folder and then Packages.
- From the Services menu, use Open Sesame to open the Package as Root

- From the Tools menu, open the Inspector and look at the Build Attributes.
- Under Framework Search Order, Set… a new path to where those files just got installed:
- Do the same for Header Search Order, but use
- Or, if you’re if you’re trying a NextStep tutorial on OpenStep, the path to the Headers is:
Now you should be able to Build in Project Builder! Note that PB doesn’t have a “Build and Go” that I can find, so once you build, you need to use Workspace Manager to find your newly made .app and double click it to test it out.
