In my current project I am unable to set the “Other Linker Flags” as I have in others projects. No matter what I put in the “Other Link Flags” section of my xcode project settings it does not show up in the detailed build log, and the desired linking does not happen:

Ld build/Debug-iphonesimulator/MyProject.app/MyProject normal i386

Is there something that would cause xcode to ignore the “Other Linker Flags?”
Where are you setting these flags? You can set flags like this at various levels in your project – project settings, target settings, etc. There’s a full description in Working with Xcode Build Settings. It’s possible that, for example, you are setting it in your project settings, and then it is being overridden by your target settings.
