c++ - 将 opencv 链接到 Visual Studio Windows 窗体应用程序

Question

我正在尝试将 opencv 链接到 Windows 窗体应用程序 VS 2010。我正在使用教程

http://linkopencvtovs.blogspot.com/2013/10/how-to-link-opencv-to-microsoft-visual.html。

它适用于控制台应用程序，但它不允许我在基于 GUI 的程序中使用 opencv 的任何功能..在下面给出错误..

错误 1 ​​错误 C2065: 'IplImage' : 未声明的标识符 c:\users\ayesha\documents\visual studio 2010\projects\abc\abc\Form1.h 130 1 abc 错误 2 错误 C3861: 'cvLoadImage': 找不到标识符 c: \users\ayesha\documents\visual studio 2010\projects\abc\abc\Form1.h 130 1 abc

代码是简单的 GUI

编译用一次

命名空间 abc {
