I’m attempting to convert an iOS (pure Objective-C) project to ARC. The conversion fails at the octest target CreateUniversalBinary stage with the following error. The project and target architecture build settings look correct to me so I am struggling to understand why this is failing:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/lipo: can’t figure out the architecture type of: /Users/andybowskill/Library/Developer/Xcode/DerivedData/Make-Up_Kit-axtbxqtkmnlfmlcafkoetwqmeufc/Build/Intermediates/Make-Up Kit.build/Debug-iphoneos/Make-Up KitTests.build/Objects-normal/armv7/Make-Up KitTests
Command /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/lipo failed with exit code 1
The aforementioned CreateUniversalBinary command is as follows:
CreateUniversalBinary “/Users/andybowskill/Library/Developer/Xcode/DerivedData/Make-Up_Kit-axtbxqtkmnlfmlcafkoetwqmeufc/Build/Products/Debug-iphoneos/Make-Up KitTests.octest/Make-Up KitTests” normal “armv7 armv7s”
cd “/Users/andybowskill/Development/iOS/Make-Up Kit”
setenv PATH “/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:/Applications/Xcode.app/Contents/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin”
lipo -create “/Users/andybowskill/Library/Developer/Xcode/DerivedData/Make-Up_Kit-axtbxqtkmnlfmlcafkoetwqmeufc/Build/Intermediates/Make-Up Kit.build/Debug-iphoneos/Make-Up KitTests.build/Objects-normal/armv7/Make-Up KitTests” “/Users/andybowskill/Library/Developer/Xcode/DerivedData/Make-Up_Kit-axtbxqtkmnlfmlcafkoetwqmeufc/Build/Intermediates/Make-Up Kit.build/Debug-iphoneos/Make-Up KitTests.build/Objects-normal/armv7s/Make-Up KitTests” -output “/Users/andybowskill/Library/Developer/Xcode/DerivedData/Make-Up_Kit-axtbxqtkmnlfmlcafkoetwqmeufc/Build/Products/Debug-iphoneos/Make-Up KitTests.octest/Make-Up KitTests”
Please could someone help to explain the error? Many thanks in advance!
I trawled my project build settings again and noticed that I had removed armv6 architecture support but still had the deployment target set to an iOS version less than 4.3. Updating the deployment target to iOS 4.3 or above resolved the problem.
