VLCKit與iOS項目中的.mm文件沖突

Question

我在我的iOS項目中使用VLCKit（MobileVLCKit.framework）。 起初，一切正常。 然后添加一些C ++代碼，因此某些文件是.mm文件。 當我編譯時，它失敗了。 Xcode日志

Undefined symbols for architecture armv7:
  "std::runtime_error::runtime_error(std::string const&)", referenced from:
      libebml::CRTError::CRTError(std::string const&, int) in MobileVLCKit(StdIOCallback.o)
  "std::ostream& std::ostream::_M_insert<void const*>(void const*)", referenced from:
      libebml::IOCallback::writeFully(void const*, unsigned long) in MobileVLCKit(IOCallback.o)
      libebml::IOCallback::readFully(void*, unsigned long) in MobileVLCKit(IOCallback.o)
  "std::runtime_error::runtime_error(std::string const&)", referenced from:

      "VTT for std::basic_stringstream<char, std::char_traits<char>, std::allocator<char> >", referenced from:

我不知道為什么以及如何解決這個問題。

我找到了解決方案：在“構建設置”中將C ++標准庫更改為libstdc ++（GNU c ++標准庫）。
