[Help-gsl] gsl and matricies |

I am eventually trying to use the GSL library to calculate the eigenvalues of
matiricies. (Mac OSX, Xcode). As best I can tell the files have all
downloaded and after much effort it appears that it finds all the needed header
files,
including gsl_matrix.h. When I try to run the sample program below I get the
effor message:"unknown symbol _gsl_matrix_alloc ". I get similar results with
gsl_matrix_float_alloc.
I can not tell where the actual code for these function are. It does not
appear to be in the header files.
Thank you for your help

int main (void)
{int i, j; gsl_matrix * m = gsl_matrix_alloc (10, 3);
for (i = 0; i < 10; i++)for (j = 0; j < 3; j++)gsl_matrix_set (m, i, j, 0.23
+ 100*i + j);
for (i = 0; i < 10; i++)for (j = 0; j < 3; j++)printf ("m(%d,%d) = %g\n", i,
j, gsl_matrix_get (m, i, j));
return 0;}
