[Help-gsl] Linking error using fft complex radix2 forward

[Jialing]

Dear Sir/Madam,

 

I tried to build a simple example that i obtained from the GNU scientific library website(http://www.gnu.org/software/gsl/manual/gsl-ref_15.html#SEC239), using visual c++ (winconsole application). but i encountered a linking error:

 

fft1.obj: error lnk2001: unresolved external symbol _gsl_fft_complex_radix2_forward

Debug/fft.exe: fatal error lnk1120: 1 unresolved externals

Error executing link.exe.

 

The program code that i have used is shown below:

//---------------------------------------------------------------------------------

#include <stdio.h>
#include <math.h>
#include <gsl/gsl_errno.h>
#include <gsl/gsl_fft_complex.h>

#define REAL(z,i) ((z)[2*(i)])
#define IMAG(z,i) ((z)[2*(i)+1])

int
Pascal WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,LPSTR IpszCmdLine,int nCmdShow)
{
  int i;
  double data[2*128];

  for (i = 0; i < 128; i++)
    {
       REAL(data,i) = 0.0;
       IMAG(data,i) = 0.0;
    }

  REAL(data,0) = 1.0;

  for (i = 1; i <= 10; i++)
    {
       REAL(data,i) = REAL(data,128-i) = 1.0;
    }

  for (i = 0; i < 128; i++)
    {
      printf ("%d %e %e\n", i, 
              REAL(data,i), IMAG(data,i));
    }
  printf ("\n");

  gsl_fft_complex_radix2_forward (data, 1, 128);

  for (i = 0; i < 128; i++)
    {
      printf ("%d %e %e\n", i, 
              REAL(data,i)/sqrt(128), 
              IMAG(data,i)/sqrt(128));
    }

  return 0;
}
//---------------------------------------------------------------------------------

Following advices from other people who encountered linking errors in gsl(http://sources.redhat.com/ml/gsl-discuss/2003-q2/msg00281.html), i added a /MD at the end of the list of settings in the Project-settings-c/c++ window, to no avail.

 

DO you have any idea how i could resolve this linking error? Please advise.

 

With thanks,

James
