Re: [Help-gsl] For help about the use of "gsl_rng_alloc" on windows

[Ralph Silva]

Hi,

I compiled your program (see below) using Cygwin  and gcc with

gcc -W -Wall -o test test.c -I/usr/include -L/usr/lib -lgsl -lm

and it worked fine. It also worked fine on Debian Etch Gnu/Linux 64bit. It
is always a good idea to use "-W -Wall" for all warnings and error messages.
Your program had two errors. Compare it with yours!

Please, read the GSL manual
www.gnu.org/software/gsl/manual/gsl-ref.html#Random-Number-Generation for
further information.

It also a good idea to use GCC and GNU/Linux.

I hope that helps you.

Best,
Ralph.

#include <stdio.h>
#include <gsl/gsl_rng.h>
#include <gsl/gsl_randist.h>
int main (void){
int i;
gsl_rng * r;
printf("running1....\n");
r = gsl_rng_alloc(gsl_rng_mt19937_1999);
printf("running2....\n");
for(i = 0;i<10;i++){
   double v = gsl_ran_flat(r,1,12);
   printf("number is %2.4f\n",v);
}
gsl_rng_free (r);
return 0;
}
