Problem Running C++ Example in the user guide

Hi all,

I'm just getting started with MKL, and I'm having some trouble running the examples in the user guide. I'm using Visual C++ 2005 (express), and have followed the directions in the guide regarding the Configuration of my Development envirornment. I am have installed MKL 9.1.027. Any help would be very much welcome.

Thanks,

TheFell

#include

"mkl.h"

typedef

struct{ double re; double im; } complex16;

extern

"C" void zdotc (complex16*, int *, complex16 *, int *, complex16

int *);

#define

N 5

void

main()

{

int

n, inca = 1, incb = 1, i;

complex16 a, b, c;

n = N;

for

( i = 0; i < n; i++ ){

a.re = (

double)i; a.im = (double)i * 2.0;

b.re = (

double)(n - i); b.im = (double)i * 2.0;

}

zdotc(&c, &n, a, &inca, b, &incb );

printf(

"The complex dot product is: ( %6.2f, %6.2f) ", c.re, c.im );

}

Suggest to use the MKL_Complex16 type defined in MKL header files,
and omit declaration of zdotc() which is already provided by "mkl.h".

So, you had to change the sample code to get it to compile. Welcome to real world.
