c++ - 获取错误 'char16_t and char32_t undeclared'

Question

我正在 Linux 上用 C++ 开发一个程序。 gcc 版本是 4.5.1 20100924。我想在我的程序中使用 std::atomic_int。我包含了如下的原子 header :

include <atomic>

当我编译程序时出现以下错误:

In file included from /usr/lib/gcc/x86_64-redhat-linux/4.5.1/../../../../include/c++/4.5.1/bits/atomic_base.h:87:0,
                 from /usr/lib/gcc/x86_64-redhat-linux/4.5.1/../../../../include/c++/4.5.1/atomic:41,

如果我包括 <cstdint> ，我得到了同样的错误。 header uchar.h 和 cuchar.h 在我的系统上不存在。如何解决编译错误？

提前谢谢你。

我错了。只需将 --std=c++0x 传递给 g++，就可以了。
