更新 OSX 命令行工具 6.3 后缺少 C++ 标头 <__debug>

从 App Store 更新到 Command Line Tools 6.3 后，程序包括<vector> or <iterator>内部包含 <__debug> 将导致文件未找到错误，如下所示。该 cpp 没什么有趣的，但包含在包含的标头之一中。

有什么想法可以解决这个问题吗？ 我不希望指定任何额外的 C++ 标志。

Thanks.

Updates:

Apple 在其开发者论坛上验证了该问题。在命令行工具 6.2 中，__debug 的包含受到如下条件保护，但在 6.3 中则不然。

#ifdef _LIBCPP_DEBUG
#   include <__debug>
#else
#   define _LIBCPP_ASSERT(x, m) ((void)0)
#endif

libcxx 人们谈论移除 __debug 的守卫here http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20140804/112292.html。感觉 __debug 在 OSX 上从来不存在。

将命令行工具降级为6.2 via Apple 的开发者下载页面 https://developer.apple.com/downloads/index.action#.

请小心下载适合您的 OS X 的正确版本：

• 操作系统 X 10.10 commandlinetoolsosx10.10forxcode6.2.dmg
• 操作系统 X 10.9 commandlinetoolsosx10.9forxcode6.2.dmg

这是有效的，因为包含__debug在命令行工具 6.2 中按如下方式有条件保护，但在 6.3 中则不然。

#ifdef _LIBCPP_DEBUG
#   include <__debug>
#else
#   define _LIBCPP_ASSERT(x, m) ((void)0)
#endif

我认为这是最安全的方法，因为：

1. 您不会损害您的工具链
2. 当 Apple 修复问题后，您可以通过 App Store 轻松升级
3. 如果您手动添加文件，则必须稍后将其删除，否则可能会出现更多问题

问题已解决由苹果公司。 安装命令行工具后6.3.1一切都按预期进行！
