I have a problem with MatLab mex. I will appreciate if you help me solve it.

I have set the compiler via 'mex -setup' and tested it by the standard example 'yprime.c' which was copied in a specific directory. Then when i try to mex my own c file 'mixer.c', there is linking problem and i can not successfully mex it! (The file mixer.c is located in the same directory as yprime.c)

I use Win 8 x64 / Matlab 2012b x64 / VS10 x32 + C++ 2010 x32, If helps.

The error is as bellow:

LINK : error LNK2001: unresolved external symbol mexFunction 
C:\Users\X550L\AppData\Local\Temp\mex_kcZP8h\templib.x : fatal error LNK1120: 1 unresolved externals 
C:\PROGRA~1\MATLAB\R2012B\BIN\MEX.PL: Error: Link of 'mixer.mexw64' failed. 
 Error using mex (line 206)
