I'm trying to use threads on my C++ application.
My code is:
#include <iostream>
#include <thread>
class C
{
public:
void * code( void * param )
{
std::cout << "Code thread executing " << std::endl;
return NULL;
}
};
int main()
{
C c;
std::thread t ( &C::code, &c );
t.join();
}
When compiling, I got those errors:
In file included from /opt/centos/devtoolset-1.0/root/usr/lib/gcc/x86_64-redhat-linux/4.7.0/../../../../include/c++/4.7.0/bits/move.h:57:0,

and a lot more...
I'm compiling with:
g++ -std=c++0x C.cpp
The compiler version:
$g++ --version
g++ (GCC) 4.7.0 20120507 (Red Hat 4.7.0-5)
What am I doing wrong?
