每次从CocoaPods导入文件时,我都会收到Apple Mach-O链接器错误.
Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_FBSession", referenced from: someFile
ld: symbol(s) not found for architecture arm64
对于我使用的各种Pod,我得到了大约12个.
我正在尝试使用XCode 5为iPhone 5S构建.
我一直在尝试使用SO的各种解决方案,但还没有任何解决方案.
如何修复Apple Mach-O链接器错误？
刚发现另一个可能有趣的警告,我希望这能引导我找到解决方案:
Ignoring file ~/Library/Developer/Xcode/DerivedData/SomeApp/Build/Products/Debug-iphoneos/libPods.a,
file was built for archive which is not the architecture being linked (arm64):~/Library/Developer/Xcode/DerivedData/someApp/Build/Products/Debug-iphoneos/libPods.a
我有一个已经存在于CocoaPods/Specs中的库的公共分支.在Podfile中,我可以通过执行以下操作来引用此分叉的pod:
pod 'CoolLibrary', :git => 'git@github.com:myname/CoolLibrary-Forked.git', :commit => 'abcdef1234567890abcdef1234567890'
我试着把它放在我的MyLibrary.podspec:
s.dependency 'CoolLibrary', :git => 'git@github.com:myname/CoolLibrary-Forked.git', :commit => 'abcdef1234567890abcdef1234567890'
但是请收到以下错误消息:
-> MyLibrary.podspec
- ERROR | The specification defined in `MyLibrary.podspec` could not be loaded.
[!] Invalid `MyLibrary.podspec` file: [!] Unsupported version requirements. Updating CocoaPods might fix the issue.
是否可以以这种方式在.podspec中指定依赖项(即对于具有podspec但不在CocoaPods/Specs中的pod)？
我正在使用firebase作为我在iOS中工作的项目的一部分,当我尝试针对iPhone 6或7模拟器进行编译以进行测试时,我偶然发现了以下链接错误.
