Three20 dependency problem

I checked out the three20 source and was trying to follow this

guide to build an iphone app using the framework. Within this guide, Templates are used which I checked out too. They ought to compile properly, but I get the following error:

File /Users/myUser/programming/three20/src/build/Debug-iphonesimulator/libThree20.a depends on itself. This target 开发者_StackOverflow中文版might include its own product.

Did anyone ever solve that issue? I read it was about including something you want to create which is not possible. Anyway any solution I found did not help here.

I actually did not even change anything! Any ideas?

Okay I fixed this by opening the three20.xcodeproj and unchecking the target box for libThree20.a (while leaving it checked in my project that is using three20).

This has at least got me building and running, will report if any problems come up later.
