VC++错误 - 语法错误：“常量”上枚举

-3

我使用立体视觉源代码，并给出了一个错误VC++错误 - 语法错误：“常量”上枚举

您能否指出源代码中的哪一行是＃117，假设它来自highgui_c.h文件。 – uesp 2012-04-17 12:06:18

在那个pasebin版本中，它是第190行的另一个错误（我试图解决它，并删除了一个;）。所以不是那个问题 – user558126 2012-04-17 12:19:27

我猜你的枚举之一是以前定义过的。例如，下面的代码段复制在VC 2010的错误消息：

#define CV_GUI_NORMAL 0x00000010 

enum 
{ 
    CV_GUI_EXPANDED = 0x00000000, 
    CV_GUI_NORMAL  = 0x00000010 
};

解决方案是明显为仅一次定义CV_GUI_NORMAL。
