Linking Problems using Visual C++ 2008 Express Edition

[fienefie]

I get the following link errors when I try to build my program in Visual C++ Express 2008 Express Edition on windows 32.

1>Linking...

I have added the code where I am getting the errors from below:

#include "mkl.h"
//utility includes (in common folder)
#include "fileIO.h"
#include "mallocCu.h"

extern void sgesv (int*, int*, float*, int*,int*,float*, int*, int*);

sgesv (&numnode, &nrhs, matforcpu, &numnode, ipvt, rhs, &numnode, &info);

if(print_mat){
outputData( matforcpu, numnode, numnode, mat_cpu_output );
}

mallocCu( numnode*numnode, &matfordev);
mallocCu( numnode, &cdev, c);
mallocCu( numnode, &nodedev, node);
mallocCu( numnode, &ncodedev, ncode);

To solve the problem, I put the include files in extern "C" but then I get an error when I do that too.

Any help will be appreciated. Thanks.

It means that compiler ( linker ) can't find source codes for that functions
