Objective C: Missing architecture

When I go to validate my app, I get the error executable is missing a required architecture. At least one of the following architectures must be present: armv6

I'm using Xcode 4.2 and the iOS5 SDK and deploying to 3.2. This never happened before I updated the SDK.

I'm also getting several warnings coming up when I build for archiving:

I found the answer on another stack question. All I had to do was add an array entry for Required device capabilities "Warning: iPhone apps should include an armv6 architecture" even with build config set

---

I just tried the same configuration and in Architectures is says: $(ARCHS_STANDARD_32_BIT) armv6. With this and target 3.2 I dont get any warning. Check your architectures is they are the same. So it seems that armv6 must be present. Just go to your Target -> Build Settings -> Architecture. Doublie-click -> others and add armv6, that should solve your problem.

project -> edit project settings -> in build tab search with "active" then unselect build active arch only

If you uncheck "Build Active Architecture Only", then it will build all the valid architectures.
