Question

我正在使用Chilkat并在安装AFNetworking后出现这些错误：

Undefined symbols for architecture armv7:
  "_res_9_query", referenced from:
      ChilkatResolve::bestMxLookup(char const*, StringBuffer&, LogBase&, bool) in libchilkatIos.a(ChilkatResolve.o)
      ChilkatResolve::dkimLookup(char const*, StringBuffer&, LogBase&, bool) in libchilkatIos.a(ChilkatResolve.o)
      ChilkatResolve::mxLookup(char const*, ScoredStrings&, LogBase&, bool) in libchilkatIos.a(ChilkatResolve.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我在网上找到了解决方案：

Add “-lresolv” to your list of link libraries.

当我搜索它时找不到-lresolv，但我找到了libresolv.9.dylib所以我添加了它，现在我收到了一个新错误：

Apple Mach-O Linker Error


206 duplicate symbols for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

还有其他人有这个问题吗？我该如何解决这个问题？

我认为错误与AFNetworking有关：

为什么一直说iphone？我正在构建一个ipad应用程序

这是我的Podfile：

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '7.0'
pod 'AFNetworking', '~> 2.5'

Answer 1

这里的问题可能是您将AFNetworking库链接两次，一次直接在您的项目上，再次通过Cocoapods。查看主项目文件的构建阶段。确保您只链接libPods而不是AFNetworking或通过Cocoapods使用的任何其他lib。这应该在链接中修复重复的符号。

重复符号_OBJC_IVAR _ $ _ AFHTTPRequestOperation._responseSerializer in
