Compile apps on my MacBook Air using Qt

I just installed XCode and the newest Qt version on my MacBook Air with SnowLeopard 10.6.7.

But when I tries to compile my application, i get an error message saying:

Code:

---

:-1: error: symbol(s) not found for architecture x86_64

---

How can I fix this?

Nvm, It was a simple slot mistake xD it works fine now.. just a strange error message.
