Dear gsl users,
I wish to use gsl in my Fortran 90 program.
So far, I've written 2 C routines as the follwing:
*#include <gsl/gsl_rng.h>
#include <gsl/gsl_randist.h>
#include "gslwr.h"
static gsl_rng* r;
void rng_initialise__(int* s)
{
r = gsl_rng_alloc(gsl_rng_taus);
gsl_rng_set(r, (unsigned long int)(*s));
void rng__(double* zetha)
{
*zetha = (double)gsl_rng_uniform_pos(r) ;
}*
And my program in Fortran 90 looks like that:
*PROGRAM random
IMPLICIT NONE
integer :: seed = 0
double precision :: zetha
call system_clock(seed)
call rng_initialise(seed)
call rng(zetha)
PRINT*, "zetha=",zetha
END PROGRAM random
*
I'm able to creat *.o file doing *icc -c gslwr.c* and *ifc -c gsl.f90*.
But when I do *ifc gsl.o gslw.o* I get
/*gsl.o: In function `MAIN__':
gsl.f90:(.text+0x2c): undefined reference to `rng_initialise_'
gsl.f90:(.text+0x36): undefined reference to `rng_'*/
Does someone understand what's wrong with this?
On the other hand I've heard about fgsl
<

Dose someone use it?
What do you think about it?
I thank you in advance,
Best,
Eric.
