Question

I am developing a program in C++ on Linux. The gcc version is 4.5.1 20100924. I want to use std::atomic_int in my program. I have included atomic header as below:

include <atomic>

When I compile the program I get below errors:

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,

If I include <cstdint>, I get the same errors. The headers uchar.h and cuchar.h are not there on my system. How can I resolve the compilation errors?

Thank you in advance.

EDITED:

I was wrong about that. just pass --std=c++0x to g++, and that would do it.
