[Help-gsl] Problems with compiling for OSX 10.3

[Elspeth Nickle and Ron Teather]

I am trying to compile the example program for generating all the 
combinations of the elements in a set using the GSL library.  I am 
using OSX 10.3.  I cannot figure out how to get the gsl libraries to 
link to my test program.

I have compiled the GSL library and it is installed in /usr/local/lib 
as libgslcblas.la and libgslcblas.a.

When I run the following command to compile the program, I get the 
following:

 ejn$ gcc -v -Wall testcomb.c

Here is the test program in case anybody would like to refer to it.

#include <stdio.h>
#include <gsl/gsl_combination.h>

int
main (void)
{
  gsl_combination * c;
  size_t i;

  printf ("All subsets of {0,1,2,3} by size:\n") ;
  for (i = 0; i <= 4; i++)
    {
      c = gsl_combination_calloc (4, i);
      do
        {
          printf ("{");
          gsl_combination_fprintf (stdout, c, " %u");
          printf (" }\n");
        }
      while (gsl_combination_next (c) == GSL_SUCCESS);
      gsl_combination_free (c);
    }

  return 0;
}


If anybody can explain to me what I am doing wrong, I would greatly 
appreciate it!  I know there are some issues with dynamic libraries and 
Mac OS X but I have compiled these libraries as suggested with 
'disable-shared.'
