Question

自定义构建的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），因此我必须手动添加：-I/usr/include/x86_64-linux-gnu/c++/4.8到命令行。 gcc找到这些文件没有问题。

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，引用标准库中的错误：

clang 3.1版目标：x86_64-unknown-linux-gnu 线程模型：posix

gcc（Ubuntu 4.8.2-19ubuntu1）4.8.2

我应该如何进一步调查？哪些信息在这里有用？

升级clang版本，clang 3.1很可能无法处理4.8 libstdc++标题。
