最近我将 google-cast-sdk 升级到最新版本，但出现如下构建错误

  /Users/kxue/Documents/ios_trunk/Pods/google-cast-sdk/GoogleCastSDK-ios-4.4.7_static/GoogleCast.framework/GoogleCast(filterkit_2a008340bdfaacbcf917e42c4c119879.o)

...

ld: 10 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

知道如何解决这个问题吗？用之前的版本google-cast-sdk 4.2.0就没有了，谢谢~

【解决方案1】：

这对我有用。

在您的项目中选择您的 iOS 目标。
选择构建设置
搜索“其他链接器标志”
双击“其他链接器标志”，它应该会弹出一个列表。如果您看到“-all_load”作为条目，请将其删除并再次尝试构建。

我遇到了同样的问题，但我的情况是因为我的内部 SDK podspec 的设置方式。根据拜伦的回答，我将子规范设置如下

s.subspec "SomeSubspec" do |sp|

  sp.platform = :ios

  // block of code to link flags according to Google Cast documentation
  // make sure to not include -all_load
  sp.pod_target_xcconfig = { 'OTHER_LDFLAGS' => '-ObjC -lc++' }
  sp.xcconfig = { 'ENABLE_BITCODE' => 'NO' }

  sp.frameworks = "framework1", "framework2"
  sp.source_files  = "somepath/*.swift"

  sp.dependency InternalSDK/Somesubspec
  sp.ios.dependency 'google-cast-sdk', '4.4.8'
  sp.ios.dependency anotherpod, '3.19.1'

  sp.test_spec "Tests" do |test_spec|
    // block of code to link flags according to Google Cast documentation
    // make sure to not include -all_load
    test_spec.pod_target_xcconfig = { 'OTHER_LDFLAGS' => '-ObjC -lc++' }
    test_spec.xcconfig = { 'ENABLE_BITCODE' => 'NO' }
    test_spec.requires_app_host = true
    test_spec.source_files = "somepath/*.swift"
  end
end
