生成zxing
下载zxing,zxing-cpp-master
https://github.com/zxing-cpp/zxing-cpp
Cmake生成项目,点Generate,把OpenCV_DIR修改了,NameValue没有报红就点Generate。然后点Open Project打开项目。
打开项目后,右击解决方案属性页,勾选后再生成解决方案。
全部生成成功后,新建一个文件夹zxing-cpp,下面有include和lib文件夹,include下再放个zxing文件夹。
复制D:/zxing-cpp-master-build/core/Debug/ZXing.lib到D:\zxing-cpp\lib文件夹下。
复制D:\zxing-cpp-master\core\src下的所有文件到D:\zxing-cpp\include\zxing文件夹下。
配置项目
新建一个项目,配置属性页
C++ ->常规-> 附加包含目录 D:\zxing-cpp\include
链接器 ->常规 -> 附加库目录 D:\zxing-cpp\lib
链接器 ->输入-> 附加依赖项 ZXing.lib
复制D:\zxing-cpp-master-build\core\Debug\ZXing.dll到 自己项目的Debug目录下( …\TestZxing\x64\Debug)。

已有opencv、zxing的环境下:文章来源:https://www.toymoban.com/news/detail-424455.html
