linux使用shared_ptr出现错误

    我在不同的系统下采用下面的方式使用shared_ptr以及vector:

std::vector<const std::shared_ptr<Object> > pointer_arrays;
std::vector<const std::shared_ptr<Object > >::const_iterator pointer_Iter;

并采用如下初始化:

const std::shared_ptr<WordData> object(new Object);
wordDataTab.push_back(object);

这样在mac os下面编译,通过并且获得正确的结果。但是我在centos 下的使用gcc编译这段代码时出现如下的编译错误:
