(error LNK2001): compiling CIN that requires mex.h

[kay88]

I'm trying to create a CIN that requires mex.h header to call Matlab functions.  However, whenever I try to compile it, I get LNK2001 errors.  I followed the LabVIEW manual on how to compile CINs and I checked my project settings etc.  I also included matrix.h and tmwtypes.h header files as required by mex.h.

Here is the beginning of my code:

#include "C:\Documents and Settings\Desktop\SINE\libsvm-mat-2.82-2\extcode.h"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <ctype.h>
#include "C:\Documents and Settings\Desktop\SINE\libsvm-mat-2.82-2\svm.h"
#include "C:\Documents and Settings\Desktop\SINE\libsvm-mat-2.82-2\mex.h"
#include "C:\Documents and Settings\Desktop\SINE\libsvm-mat-2.82-2\svm_model_matlab.h"

typedef struct {
    int32 dimSize;
    float64 elt[1];
    } TD1;
typedef TD1 **TD1Hdl;

#define CMD_LEN 2048

MgErr CINRun(LStrHandle ModelFileName, TD1Hdl Labels, TD1Hdl attributes,
             TD1Hdl predictedlevel);

MgErr CINRun(LStrHandle ModelFileName, TD1Hdl Labels, TD1Hdl attributes,
             TD1Hdl predictedlevel);


Here are the error messages I am receiving:

Thanks a lot

Or is there any other way that I can call a C code from Labview that requires calling matlab as well?
Thanks again

kay88,

You could create a DLL and call that from LabVIEW.

What compiler are you using to create your CIN?
