Sometimes when i try to \"build\"/compile a downloaded source, i get following warning:
ld: warning: directory \'/Volumes/Skiiing2/CD/ViewBased/Unknown Path/
I just upgraded to iPhone SDK version 3.2, and ran into this problem. It looks like it happens on all my projects that were created with the 3.1.2 SDK.
After some amount of searching, I finally was able to find it in the project settings. You have to "Get Info" on the target to find it. Click the "Build" tab, and scroll down to "Search Paths". It can be deleted from there.
Hope that helps...
