LINK : fatal error LNK1181: cannot open input file 'cv.lib'

Question

i have been stuck with this problem since yesterday, and i cant figure it out. im already following the steps from this pdf http://www.mathworks.in/matlabcentral/fileexchange/21818-opencv-and-mex-files-quick-guide

and this is my mexopts.bat looks like :

@echo off

but i got an error like this :

LINK : fatal error LNK1181: cannot open input file 'cv.lib'

C:\PROGRA~1\MATLAB\R2012B\BIN\MEX.PL:
Error: Link of 'displayimage.mexw64' failed.

Please help me to solve this, and thanks in advance. by the way im using Matlab R2012b and OpenCV 2.4.9

Answer 1

those missing 3 opencv libs were used with like opencv 1.0. long time ago. but no more.

set LINKFLAGS=/dll /export:%ENTRYPOINT% /LIBPATH:"%OPENCVDIR%" cv.lib highgui.lib cvaux.lib cxcore.lib 

the current names of the opencv_libs are like opencv_core248.lib, opencv_highgui248.lib, etc. look inside that %OPENCVDIR%\x64\vc10\lib folder and instead add what you find there.

Answer 2

according to this site http://msdn.microsoft.com/en-us/library/y6b12xkc%28v=vs.100%29.aspx., the particular error code results when the file can not be found.

Also, I think that I gotten this error message when I accidentally mixed 32-bit and 64-bit libraries, but that is just a vague recollection.
