Question

我正在开发一个项目，它是一个cocoa静态库，它使用了由其他人编写的C ++库。这个C ++库使用了C ++ 11和libc ++（支持C ++ 11的LLVM C ++标准库）。

我成功构建了cocoa库，但是当我在App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：

看起来像关于链接C ++ 11库的问题，但我不知道它。也许链接APP中使用libstdc ++标准的cocoa静态库，没有C ++ 11标准，所以冲突发生在这里。但我不确认这一点。

你能帮帮我吗？

由于

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。

IOS目标链接可可堆栈库，其中库编写了C ++ 11标准错误
