Question

我有以下代码：

#include <type_traits>

int main()
{
}

g ++ file.cc -std = c ++ 0x

工作正常。

但是，我出于某种原因需要使用clang ++。

当我尝试

时

clang ++ file.cc -std = c ++ 0x

我收到了一堆错误：

In file included from file.cc:1:
In file included from /usr/include/c++/4.4.4/type_traits:50:

clang ++ --version给出：

clang version 2.8 (branches/release_28)
Target: x86_64-redhat-linux-gnu
Thread model: posix

任何想法如何解决？（-std = c ++ 11不起作用，无法识别。）

Answer 1

Clang 2.8不支持C ++ 11功能，您需要升级编译器才能使用它们。

为什么不clang ++编译以下代码？
