如何配置VS 2022 ?
第一步:打开窗口顶部 【项目】菜单,选中 【<某某项目>属性】。
第二步:在打开的对话框中,左侧菜单选择 【C/C++】=> 【常规】,选中右侧附加包含目录中,点击右侧出现的向下箭头,点击编辑,在打开的对话框中如下填写:
其中 D:\ws\vc\emptycam\hkheader 文件夹放着海康的头文件,分别是: DataType.h、DecodeCardSdk.h、HCNetSDK.h、plaympeg4.h。
第三步:左侧菜单选择 【链接器】=> 【常规】。右侧选中附加库目录,点击右侧小三角,点击编辑,打开对话框。
文件夹 D:\ws\vc\emptycam\hkdll 是放海康dll文件的地方。文件如下图所示:
第四步:左侧菜单选择 【链接器】=> 【输入】。右侧选中【附加依赖项】点击右侧小三角,点击编辑,打开对话框。内容按照图片里的文字进行填写。
