windows golang ./opencv.h:10:10: fatal error: opencv/cv.h: No such file or directory

This error indicates that the compiler is unable to find the header file "opencv/cv.h" which is required for the program to compile successfully.

To resolve this error, you need to ensure that you have installed the OpenCV library and have included the correct path to the header files in your code.

Here are the steps to fix this error:

1. Install OpenCV library on your system. You can download the latest version of OpenCV from the official website (https://opencv.org/releases/).

2. Once you have installed OpenCV, locate the directory where the header files are stored. In most cases, the header files are stored in the "include" directory within the OpenCV installation directory.

3. Update your code to include the correct path to the header files. You can use the following code snippet to include the path to the header files:

#include <opencv2/opencv.hpp>

4. Compile your code again and the error should be resolved.

If you are still facing issues, you can try updating your system's environment variables to include the path to the OpenCV library directory.
