【问题描述】：
定制的 clang 3.1 无法从 libc++ 中找到一些与机器相关的包含文件（如 bits/c++config.h），所以我不得不手动添加：-I/usr/include/x86_64-linux-gnu/c++/4.8 到命令行。 gcc 可以毫无问题地找到这些文件。
现在我正在尝试用 clang++ 编译一个文件。 gcc(with the same options) 编译它，只抱怨一堆警告，当 clang++ 无法做到这一点时，指的是标准库中的错误：

我应该如何进行进一步调查？什么信息在这里有用？
【问题讨论】：
-
你试过用 -lstdc++ 选项编译吗？
-
刚试过 - 没有任何改变
-
请注意：“bits/c++config.h”不是libc++文件；它是一个 libstdc++ 文件。该文件开始于： // 此文件是 GNU ISO C++ 库的一部分。
