XCode:架构arm64错误的未定义符号 [英] XCode: Undefined symbols for architecture arm64 error
问题描述
在我的XCode 5项目中,我使用RestKit进行REST通信。
使用模拟器一切正常,但生成ipa文件,我收到以下错误:
In my XCode 5 project I use RestKit for REST communication. Everything works fine with the simulators, but generating the ipa file, I get the following error:
ld: warning: ignoring file /Users/joseph/Library/Developer/Xcode/DerivedData/XXXXXXXXXX-gdwdekevxtdfivfpsnmyykeqhulk/Build/Products/Debug-iphoneos/libRestKit.a, missing required architecture arm64 in file /Users/joseph/Library/Developer/Xcode/DerivedData/XXXXXXXXXXXXX-gdwdekevxtdfivfpsnmyykeqhulk/Build/Products/Debug-iphoneos/libRestKit.a (2 slices)

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation).
如果在RestKit项目中,我更改了Build Settings - >Architectures中的标准体系结构 (ARMv7,armv7s)通过标准架构(包括64位)(ARMv7,armv7s,arm64)选项,一切编译都很好。这是正确的吗?,不会带来任何结果,我必须更改其他一些设置。
If in RestKit project, I change in "Build Settings" -> "Architectures" the "Standard architectures (ARMv7, armv7s)" by Standard architectures (including 64-bit) (ARMv7, armv7s, arm64) option, everything compiles fine . Is this correct?, Does not bring any result, I have to change some other settings.
推荐答案
这只是意味着你正在建设您的项目也适用于64位(iPhone 5s),无需担心,请参阅此链接以获取更多解释:

It just means you are building your project also for 64bit (iPhone 5s) and nothing to worry about, see this link for some more explanations: Xcode 5 and iOS 7: Architecture and Valid architectures
