码：

#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>

using namespace cv;

int main ( int argc,char **argv )

    imwrite("001-bw2.jpg",img_final);

输出：

我怎样才能解决这个问题？文件’opencv_core231d.lib’已经存在,为什么会出现此错误？

右键单击该项目,然后转到Properties-> Linker-> Additional Library目录.添加此列表的路径.

生成以下错误
链接：致命错误LNK1181：无法打开输入文件’libclamav.lib’

请指导我

您可以将包含libclamav.lib库文件的目录添加到LIBPATH以解决问题(此说明可能会有所不同,具体取决于您的Visual Studio版本)：

>在“解决方案资源管理器”中,右键单击该项目,然后单击“属性”.
>在“属性页”对话框中,展开“链接器”,然后单击“常规”.
>在Additional Library Directories字段中,指定libclamav.lib所在的路径.

当LIBPATH包含空格时,也会发生错误.如果是这种情况,请将库移动到没有空格的路径或在路径周围加上引号.

Fatal error LNK1104: cannot open file 'wxbase28d.lib'

之后我在以下设置中添加了一些变量：

C/C++ – >预处理器定义：

WIN32;__WxmsW__;_WINDOWS;_DEBUG;__WXDEBUG__;_CRT_SECURE_NO_WARNINGS;WIN32;_DEBUG;_WINDOWS;%(PreprocessorDeFinitions)

Linker-> General->其他图书馆目录：

资源 – >常规 – >其他包含目录：

有人能帮助我发现我做错了什么吗？
