我有一个名为 Video 的类，定义如下：

class Video
{
public:
    Video() { }
    ~Video()
    {

    }

    unsigned int m_max_ad_duration;
    unsigned int m_max_skippable_duration;
    unsigned int m_start_delay;
    unsigned short int m_inventory_type;
    unsigned short int m_skippable_Request;
};

如果我在一个名为 Video.h 的新文件中有上述内容，则构建工作正常，但是当我在包含许多类的现有文件中声明上述内容时，构建失败并出现错误，例如

../../include/CampaignCache.h:33:56: error: ‘Video’ was not declared in this scope
../../include/CampaignCache.h:33:62: error: template argument 1 is invalid
../../include/CampaignCache.h:33:62: error: template argument 2 is invalid
../../include/CampaignCache.h:33:64: error: template argument 2 is invalid
../../include/CampaignCache.h:33:64: error: template argument 5 is invalid
../../include/CampaignCache.h:33:89: error: invalid type in declaration before ‘;’ token
../../include/CampaignCache.h:97:51: error: ‘Video’ has not been declared
make[2]: *** [BaseOpenRTBBidRequest.o] Error 1
make[2]: Leaving directory `/home/asif/RTB3.0trunk/trunk/3.0/src/bidder/ssp/OpenRTB'
make[1]: *** [OpenRTB] Error 2
make[1]: Leaving directory `/home/asif/RTB3.0trunk/trunk/3.0/src/bidder'
make: *** [compile] Error 2

理想情况下，我希望文件中的 Video 类带有子类，有人可以解释为什么一个会导致构建错误而另一个不会？

我只是简单地将视频类放在一个独立的文件中，一切都开始正常工作
