To link OpenCV with C++ manually, you need to follow these steps:


Step 1: Install OpenCV

  • Download and install OpenCV from the official website (https://opencv.org/releases/).
  • Make sure to remember the installation directory.


Step 2: Create a C++ source file

  • Create a new C++ source file (e.g., main.cpp) and write your code.


Step 3: Include OpenCV headers

  • Include the necessary OpenCV headers at the beginning of your source file. For example:
1
2
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>


Step 4: Specify OpenCV library path

  • Open your compiler settings and specify the path to the OpenCV library.
  • Add the path to the OpenCV lib directory as an additional library directory.


Step 5: Link OpenCV libraries

  • Link the necessary OpenCV libraries to your project during the linking phase.
  • Append the following libraries to the linker settings: opencv_core, opencv_highgui, and any other required libraries.


Step 6: Build and run

  • Build your C++ program to compile and link it with OpenCV.
  • Run your program and verify that it runs successfully.


Note: The exact steps may vary depending on your compiler and operating system.
