New comer's question!

fanhanqi — Sat, 11 Mar 2006 19:57:07 GMT

I am a new comer to the MKL.

My IDE is VC++.net, and MKL is 8.0.1

Here is my test code, and the following is the linkage error. I don't know what to do with them.

#include

#include "mkl.h"

extern "C" void sgemm(char *transa,char *transb,int *m,int *n,int *k,float *alpha,float *a,int *lda,float *b,int *ldb,float *beta,float *c,int *ldc);

void main()

{

float alpha = 1.0f;

float beta = 1.0f;

char transa = 'n';

char transb = 'n';

int m = 3;

int n = 3;

int k = 3;

float *a = new float[9];

float *b = new float[9];

float *c = new float[9];

for ( int i = 0; i 9; ++i ){

a = 1.0f;

b = 2.0f;

c = 0.0f;

}

sgemm( &transa, &transb, &m, &n, &k, α, a, &m, b, &n, β, c, &n );

}

Add libguide to the list of linked libraries. This should be called out in examples provided with MKL.

I'm having a similar problem. Added libguide.lib, but now it complains about missing libirc. Any tips?

Thanks!

You are trying to use statical version of libguide. Statical libguide have dependences from libirc. You can resolve linkage problems by two ways:

1) use libirc library at linkage stage of your project

2) use dinamical version of libguide - link libguide40.lib instead libguide.lib
