Xcode 3.2.3 Problems and Solutions
Upgrading to Xcode 3.2.3 can give you a few problems at first, but here's how I've found out how to fix those issues.
Problem
Immediately when opening older files you're going to get a "Missing Base SDK" error.
Solution
Under the Groups & Files panel, you'll see a group called Targets. Expand the Targets group and double click on your project name.
Make sure you're in the Build panel.
Under Architectures, change the Base SDK to iPhone Device 3.2 or above.
Problem
OpenFrameworks iPhone projects won't compile, most common issue is a DWARF issue.
Solution
1. Download the mac version of OF.
2. In the mac version, navigate to libs/FreeImage/lib/osx/
3. Copy the file "freeimage.a" to libs/FreeImage/lib/iPhone
4. In the iPhone version, rename "libFreeImage_iphone_universal.a" to "libFreeImage_iphone_universal_iphone.a"
5. Rename "freeimage.a" to "libFreeImage_iphone_universal.a"
