This document provides instructions for installing OpenCV 2.0 and Dev C++ and configuring the compiler settings and directories in Dev C++ to allow OpenCV code to compile. Key steps include installing OpenCV 2.0 and Dev C++, adding OpenCV compiler options, and configuring the binaries, libraries, and include directories to point to the OpenCV install locations. The document also provides instructions for a sample cvTest.cpp program to display an image using OpenCV.

cxoperations.h

17. Modify the code in line 68
• #if __GNUC__ >= 4 || __MINGW32__

18. Ready to GO
• Put an image under the same folder with “cvTest.cpp”.
• Try to compile and run (F9) “cvTest.cpp” with Dev C++
• You may need to update the image’s name in “cvTest.cpp”,
including the filename extension (i.e. image type like .bmp /
.jpg / .png …)

19. cvTest.cpp
• Put the image under the same folder with “cvTest.cpp”
• Update the image’s name to filename[]

20. cvTest.cpp
• Compile and Run (F9)

21. cvShowImage
•
