c++ - IOS 目标链接 Cocoa 堆栈库，该库具有 C++11 标准错误中写入的库

Question

我正在做一个项目，它是一个 Cocoa 静态库，它使用了其他人编写的 C++ 库。这个 C++ 库使用了 C++11 和 libc++(支持 C++11 的 LLVM C++ 标准库)。

我成功地构建了 cocoa 库，但是当我在应用程序中链接这个库时(只需在“Link Binary with Libraries”中添加链接)。

发生错误，这是错误日志:

看起来像是关于链接 C++11 库的问题，但我对此一无所知。也许在APP中链接cocoa静态库使用了libstdc++标准，没有C++11标准，所以冲突就在这里发生了。但我不证实这一点。

你能帮帮我吗？

谢谢

Answer 1

因为我错过了链接 libc++.dylib 库。

因此产生这些错误。

注意:Clang 支持 C++11。
