XCode 4.3 - Build error “missing required architecture armv7”

Question

After upgrade XCode from 4.2 to 4.3 I\'ve got below problem. I can\'t build it. Do you guys have idea how can I resolve this problem? even some clue would be helpful to me.<

Answer 1

I was getting the same linking error for the Simulator after upgrading from Xcode 4.2 -> 4.3.1. I noticed that new projects in 4.3.1 do work with Unit Tests, so just compared the project differences.

What fixed it for me was:-

1. Select Project in project navigator
2. Select Test Target
3. Select Build Settings
4. Go down to Framework Search Paths and single-click it
5. Delete whatever is there
6. Enter $(SDKROOT)/Developer/Library/Frameworks $(DEVELOPER_LIBRARY_DIR)/Frameworks
7. If you had any custom frameworks, add those back

Actually, Unit Tests run fine on the Device, too.
