Problems with OpenCV and VC++

edit

I have configured Opencv 2.4.2 with Visual C++ 2010 Express Edition. I have linked and included all files. Now when I compile any file , complier gives error "LINK : fatal error LNK1104: cannot open file 'opencv_core231d.lib'".

I searched the OPENCV folder where I have extracted the files , there is no 'opencv_core231d.lib' there. How can I reslove this problem.

Infact there are no '231.lib' in lib directory of OPENCV/ I have opencv_core242d.lib file
