缺少C ++标头< __ debug>更新OSX命令行工具6.3 [英] Missing C++ header <__debug> after updating OSX Command Line Tools 6.3

问题描述

从App Store更新到命令行工具6.3后，包括< vector> 或< iterator> 其中内部包括< __ debug>将导致文件未找到错误如下。

有任何想法来解决这个问题吗？
我不希望指定任何额外的C ++标志。

谢谢。

更新：

由苹果在他们的开发者论坛。在命令行工具6.2中，包含__debug的条件保护如下，但不在6.3中。

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

和libcxx人谈到删除__debug的守卫此处。

解决方案

将命令行工具降级到 6.2 via < a href =https://developer.apple.com/downloads/index.action#> Apple的开发人员下载页面。

小心下载您的OS X的正确版本：

• OS X 10.10 commandlinetoolsosx10.10forxcode6。 2.dmg


• OS X 10.9 commandlinetoolsosx10.9forxcode6.2.dmg

这样做是因为包含 __ debug 命令行工具6.2但不是6.3。

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

在我看来，这是最安全的方法，因为：

1. 你不会妥协你的工具链


2. 当Apple修复问题时，您可以通过App Store轻松升级


3. 如果手动添加文件，您必须稍后删除，
> Apple修正问题已修复。
安装命令行工具 6.3.1 后，一切正常工作！



After updating to Command Line Tools 6.3 from the App Store, programs including <vector> or <iterator> which internally include <__debug> will cause file not found error as follows. The cpp is nothing interesting but includes in one of the included headers.

#include <__debug>
         ^

Any ideas to fix this? I don't expect to specify any additional C++ flags.

Thanks.

PS: MacBook pro on OSX 10.10.3

Updates:

The issue is verified by Apple on their developer's forum. In Command Line Tools 6.2, the inclusion of __debug is conditionally guarded as follows but not in 6.3.

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

And libcxx people talked about removing the guards of __debug here. It feels like __debug never exists on OSX.

解决方案

Downgrade the Command Line Tools to 6.2 via Apple's Developer Download Page.

Be careful to download the correct version for your OS X:

• OS X 10.10 commandlinetoolsosx10.10forxcode6.2.dmg
• OS X 10.9 commandlinetoolsosx10.9forxcode6.2.dmg

This works because the inclusion of __debug is conditionally guarded as follows in Command Line Tools 6.2 but not in 6.3.

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

In my opinion this is the safest way, because:

1. You don't compromise your toolchain
2. You can easily upgrade via the App Store when Apple fixes the issue
3. If you add a file manually you have to delete it later or more problems could occur

Update - 21.04.2015

Problem fixed by Apple. After installing Command Line Tools 6.3.1 everything works as expected!
