clang error: c++/4.8/bits/stl_iterator_base_types.h:227:29: error: no type named 'iterator_category' in 'std::iterator_traits<unsigned long>'
clang error: c++/4.8/bits/stl_iterator_base_types.h:227:29: error: no type named 'iterator_category' in 'std::iterator_traits<unsigned long>'
自定义构建的 clang 3.1 无法从 libc++ 中找到一些依赖于机器的包含文件（如 bits/c++config.h），因此我不得不手动添加：-I/usr/include/x86_64-linux-gnu/c++/4.8 到命令行中。 gcc 可以轻松找到这些文件。
现在我正在尝试用 clang++ 编译一个文件。 gcc（使用相同的选项）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：

gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2
我应该如何进行进一步调查？什么信息在这里有用？
升级你的clang版本，很可能clang 3.1无法处理4.8 libstdc++ headers.
