Technical Q&A QA1760

iPhone/iPod Touch: application executable is missing a required architecture. At least one of the following architecture(s) must be present: armv6

A: You are getting the " missing a required architecture." message for one or more of the following reasons:

Your Architecture at the Target Level build settings does not contain the armv6 architecture.
Use the "Other" option in the Architecture pop-up menu (see Figure 1) to add armv6 to the Architecture build setting as seen in Figure 2.

Your Build Active Architecture ONLY build setting is set to YES.
Setting Build Active Architecture ONLY to YES indicates that you only wish to build your application for the native architecture, which is armv7 in Xcode 4. Make sure that Architecture includes armv6, then set Build Active Architecture ONLY to NO as seen in Figure 3 to build your application for armv6.
