Error building restkit for iOS Simulator

Question

I am having trouble building an iPhone project for iOS Simulator. Building for the device actually works. The error is with the RestKit external library. Here is what I get:

ld: warning: ignoring file /Users/omar/Library/Developer/Xcode/DerivedData/Zolkin-geukgbaipukxjhacrofvkapbkmme/Build/Products/Debug-iphonesimulator/libRestKit.a, file was built for archive which is not the architecture being linked (i386): /Users/omar/Library/Developer/Xcode/DerivedData/Zolkin-geukgbaipukxjhacrofvkapbkmme/Build/Products/Debug-iphonesimulator/libRestKit.a

Any help would be greatly appreciated...

This often means the .m file is not listed under Compile Sources in Build Phases of your target. Sometimes Xcode makes you add the .m file manually.

try this

TargetSettings -> Build Phases -> Compile Sources -> add your .m class ->Build and Run

The other thing to look out for are name conflicts. Make sure all your classes are uniquely named or you might get a similarly cryptic clang error

If none of that works check out this thread. It's possible, if you're running in a simulator, that it is trying to use the wrong processor architecture.

file was built for archive which is not the architecture being linked (i386)
