Hi,
I am new to using the GSL so I apologize in advance if there is a
very easy
fix to my silly problem.
I am trying to run this code which I found on the GSL website, just
to check
that I am able to use the functions.
#include <stdio.h>
#include <gsl/gsl_rng.h>
#include <gsl/gsl_randist.h>
int
main (void)
{
const gsl_rng_type * T;
gsl_rng * r;
int i, n = 10;
double mu = 3.0;
/* create a generator chosen by the
environment variable GSL_RNG_TYPE */
gsl_rng_env_setup();
T = gsl_rng_default;
r = gsl_rng_alloc (T);
/* print n random variates chosen from
the poisson distribution with mean
parameter mu */
for (i = 0; i < n; i++)
{
unsigned int k = gsl_ran_poisson (r, mu);
printf (" %u", k);
}
printf ("\n");
gsl_rng_free (r);
return 0;
}
It gives me the following error: " error LNK2019: unresolved
external symbol
_gsl_rng_default referenced in function _main ".
Have I not installed GSL properly? I've already tried out a few
functions
such as creating a matrix and using Cholesky decomposition without any
problems. I am using VC++ Express 2005.
Thank you,
Kevin
The linear algebra functions, and the randon number functions are in
different libraries.
You need to add the correct library when linking.
