c++ - g++ 不能在 Mac OS X Mavericks 上编译

Question

我的新 MacBook 和 Mac OS X Mavericks 有点问题。 在我的 Linux 机器上，我的代码编译没有问题，但在我的 Mac 上，我收到我不理解的神秘错误消息。

例如这样的事情:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/c++/v1/list:240:62: error: 
  invalid use of non-static data member '__ptr_'
explicit __list_iterator(__node_pointer __p) _NOEXCEPT : __ptr_(__p) {}

有人可以帮帮我吗？我真的不知道该怎么办...

编辑: 所以...这是错误日志中的更多信息。这是第一部分。完整的日志太长了...

Answer 1

您在第 71 行的 nr3.h 中定义一个名为 throw 的宏。这与 throw< 的使用冲突 C++ 标准库中的关键字。

一个简单的解决方案是将宏命名为其他名称，例如 MY_PROJECT_THROW。

无论如何，最好为您定义的所有宏添加一个唯一字符串前缀，以防止此类名称冲突。
