体系结构x86_64的未定义符号:"std :: terminate()",引用自

Question

我react-native run-ios在升级后的RN 运行到0.26.0-rc后运行时出错.

Undefined symbols for architecture x86_64:
      "std::terminate()", referenced from:
      ___clang_call_terminate in libReact.a(RCTJSCExecutor.o)
  "___cxa_begin_catch", referenced from:
      ___clang_call_terminate in libReact.a(RCTJSCExecutor.o)
  "___gxx_personality_v0", referenced from:

      -[RCTJavaScriptContext init] in libReact.a(RCTJSCExecutor.o)
      -[RCTJavaScriptContext invalidate] in libReact.a(RCTJSCExecutor.o)
      _RCTNSErrorFromJSError in libReact.a(RCTJSCExecutor.o)
      +[RCTJSCExecutor runRunLoopThread] in libReact.a(RCTJSCExecutor.o)
      -[RCTJSCExecutor init] in libReact.a(RCTJSCExecutor.o)
      -[RCTJSCExecutor context] in libReact.a(RCTJSCExecutor.o)
      ...
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我该如何解决？

Answer 1

运行后解决了以下建议rnpm-plugin-upgrade@0.26:

[...]加-lc++在Other Linker Flags你的Xcode项目构建设置.

正如评论中指出的那样更新目标构建设置(而不是项目).您可能还需要更新测试目标.

当我将 Facebook SDK 添加到我的项目时，出现以下错误：

这解决了我的问题： Build Phases--> Link Binary With Libraries--> 添加“ libc++.tbd”。
