shared_ptr.hpp(321) : error C2039: 'type_info' : is not a member of 'std' 错误修正

vc＋＋ 6.0使用boost::shared_ptr（boost版本boost_1_33_1）出现以下错误：

跟踪发现，原来错误的代码出现在(红色处)：

 

void * _internal_get_deleter(std::type_info const & ti) const
    {
        return pn.get_deleter(ti);
    }

 

将代码中的 std::一一 去掉后（搜索一下，有好几处），居然编译通过。

 

 

分析原因：

         type_info 为运行时类型识别功能提供支持，vc＋＋6.0 环境中自带了TYPEINFO.H头文件（在路径C:/Program Files/Microsoft Visual Studio/VC98/Include下），而该文件中定义的class type_info 并不在std 的namespace中。
