VS 编程常见错误及解决方法

1. VS2013 无法打开包括文件:“cv.h"等一些头文件

解决方法：

cv.h是build\include文件夹下的头文件，所在文件夹位置是D:\Program Files (x86)\opencv\build\include\opencv，必须将这个路径添加到OpencvDebugConfiguration.props（见上一篇）中：

 

 

2.

错误一：必须属性”VSIstallDir”缺失或为空 

解决方式：选择菜单栏的项目->属性->配置属性->常规->平台集成工具，选择V90编辑为V100，点击确定。之后运行就不会再出现必须属性”VSInstallDir”缺失或为空的错误了。 

错误二：找不到projectname.exe 
 
解决方式： 
1、选择菜单栏的项目->属性->配置属性->VC目录->包含目录->编辑 
 
添加：matlab安装目录\extern\include，然后点击确定 

2、选择菜单栏的项目->属性->配置属性->VC目录->库目录->编辑 
添加：matlab安装目录\extern\lib\win64\microsoft 

3、选择菜单栏的项目->属性->配置属性->C++->常规->附加包目录->编辑，添加：libmx.lib;libeng.lib;libmat.lib; 点击确定 

4、选择菜单栏的项目->属性->配置属性->链接器->输入->附加依赖项->编辑，添加：libmx.lib;libeng.lib;libmat.lib; 点击确定

5、选择菜单栏的解决方案平台，选择win64(倘若没有这个选项，则选择配置管理器->选择平台->新建->选择win64->确定即可) 

最后得到运行结果：
