在gcc 4.6.4中编译boost :: move
我有一个函数使用Boost :: move来移动一个锁 -
/**
* Moving assignment operator transfers ownership of the lock
*/
const_iterator& operator=(const_iterator && other) {
if (this != &other) {
iter = other.iter;
lock = boost::move(other.lock);
}
return *this;
}
我可以使用gcc 4.7.3和-std = c ++ 11或-std = c ++ 0x标志来获得此代码。 但是，对于gcc 4.6.4，即使使用-std = c ++ 0x标志，该代码也会失败。 有想法该怎么解决这个吗？
CMAKE标志用于使用C ++ 11功能：
set(CMAKE_CXX_FLAGS "-std=c++11")
CMAKE标志用于使用C ++ 0x功能：
set(CMAKE_CXX_FLAGS "-std=c++0x")
我用gcc 4.6.4得到的错误：

使用gcc 4.3测试Boost 4.6可以工作。
