OpenCV-2.1.0 using CMake and Visual C++ 2010

Test on Windows7 SP1 32-bit
Pre-Requisites

• Microsoft Visual C++ 2010.
• CMake 2.6.4.
• CMake 2.8.2.

CMake OpenCV 2.1.0

1. Download OpenCV-2.1.0-win.zip
2. Extract to ‘C:\Program Files\’
3. Create new folder: ‘C:\Program Files\OpenCV-2.1.0\build‘
4. Start -> Programs -> CMake 2.8 -> CMake (cmake-gui).
   • Where is the source code: ‘C:/Program Files/OpenCV-2.1.0/’
   • Where to build the binaries: ‘C:/Program Files/OpenCV-2.1.0/build‘

• ‘Configure’
• Specify the generator for this project: ‘Visual Studio 10’
• Use default native compilers: ‘radio’
• ‘Configure’
• ‘Generate’

Build OpenCV 2.1.0

• Start -> Programs -> Microsoft Visual Studio 2010 Express -> Microsoft Visual C++ 2010 Express
  • File -> Open -> Project/Solution…’C:\Program Files\OpenCV-2.1.0\build\OpenCV.sln‘
  • After MSVC has finished parsing all of the files (It will say ‘Ready’ in the bottom left corner): Debug -> Build Solution

After some time, OpenCV should build successfully.

OpenCV 2.1.0 HelloWorld

• To permanantly include necessary .dll files, add ‘C:\Program Files\OpenCV-2.1.0\build\bin\Debug’ to PATH by visiting Advanced tab in System of Windows. (add to system path manually)
• Start -> Programs -> Microsoft Visual Studio 2010 Express -> Microsoft Visual C++ 2010 Express
  • File -> New -> Project
  • Name: ‘OpenCV_Helloworld’…’OK’…’Finish’

Configure Project Directories

• Project -> OpenCV_Helloworld Properties…Configuration Properties -> VC++ Directories
• Include Directories…add: ‘C:\Program Files\OpenCV-2.1.0\include\opencv;’
• Library Directories…add: ‘C:\Program Files\OpenCV-2.1.0\build\lib\Debug;’
• Source Directories…add: ‘C:\Program Files\OpenCV-2.1.0\src\cv;C:\Program Files\OpenCV-2.1.0\src\cvaux;C:\Program Files\OpenCV-2.1.0\src\cxcore;C:\Program Files\OpenCV-2.1.0\src\highgui;C:\Program Files\OpenCV-2.1.0\src\ml;’
• Linker -> Input -> Additional Dependencies…add: ‘cv210d.lib;cxcore210d.lib;highgui210d.lib;‘

#include “stdafx.h”

#include <cv.h>
#include <cxcore.h>
#include <highgui.h>

int _tmain(int argc, _TCHAR* argv[])
{
IplImage *img = cvLoadImage(“funny-pictures-cat-goes-pew.jpg”);
cvNamedWindow(“Image:”,1);
cvShowImage(“image:”,img);

cvWaitKey();
cvDestroyWindow(“Image:”);
cvReleaseImage(&img);

return 0;

ปล. ติดตั้งจาก OpenCV-2.1.0-win32-vs2008.exe (ไม่ได้ใช้ CMake) แล้วกำหนดค่า Proproties ของ Project ตามข้างบนแล้ว แต่เวลา run แล้วเกิด Error ดังนี้ “The application was unable to start correctly (0xc0150002)” ทางแก้คือ เปลี่ยนจาก ‘cv210d.lib;cxcore210d.lib;highgui210d.lib;‘  เป็น ‘cv210.lib;cxcore210.lib;highgui210.lib;‘ http://opencv-users.1802565.n2.nabble.com/Application-failed-to-start-correctly-0xc0150002-td4107823.html
