先下载海康SDK
我下载的win64版本: 海康SDK官网下载
解压后得到库文件和头文件
头文件
库文件
新建QWidget项目,选择64位的kits工具,在pro目录新建include文件夹和libs文件夹
进入解压好的海康库文件所在目录,将全部文件复制到libs里
进入解压好的海康头文件所在目录,将全部文件复制到include里
在.pro文件里加入以下代码:
INCLUDEPATH += \-L. $$PWD\include# "-L. $$PWD" 表示pro所在目录LIBS += \-L. $$PWD/libs/HCCore.lib \-L. $$PWD/libs/HCNetSDK.lib \-L. $$PWD/libs/PlayCtrl.lib \-L. $$PWD/libs/HCNetSDKCom\HCAlarm.lib \-L. $$PWD/libs/HCNetSDKCom\HCGeneralCfgMgr.lib \-L. $$PWD/libs/HCNetSDKCom\HCPreview.lib
遇到乱码问题需要将HCNetSDK.h文件保存为带bom的utf8格式
头文件:
