Xcode4 Linking Problem. File was built for archive which is not the architecture being linked (arm6)

Asked 2011-03-14T20:14:02.877

Recently, I switched to Xcode4 and when I compile my project I got following error.

ld: warning: ignoring file /Users/myname/Library/Developer/Xcode/DerivedData/appname-hezrgyqimckztgbdlslkavphdclw/Build/Products/Debug-iphoneos/libTapkuLibrary.a, file was built for archive which is not the architecture being linked (armv6)
Undefined symbols for architecture armv6:
  "_OBJC_CLASS_$_TKLoadingView", referenced from:
      objc-class-ref in RootViewController.o

I opened the TapkuLibrary and checked that it's Architectures set to 'Standard (armv6 armv7)'.

What can I do to fix this problem?

I met this problem when I upgraded the XCode to 4.5 and iOS to iOS6. For GMGridView, it just happened. Not for simulator, but only for device.

I fixed this by the following steps: 1) Go to GMGridView project -> Build Settings 2) Under Setting -> Architectures, select "Standard (armv7, armv7s)"

Then clean all (including DerivedData) and rebuild.

Hope it helps!

I had this problem with the Three20 library. The thing that finally did it for me was switching the Project Format from Xcode 3.1 to Xcode 3.2 - leaving 'build active arch only' as "no".
