Hi!
        
        I've got problems using GSL library in CDT. If I try to compile
        this program
        undefined reference error occurs.   
        
        #include<stdio.h>
        #include<gsl/gsl_sf_bessel.h>
        
        
        int main (void)
        {
        double x = 5.0;
        double y = gsl_sf_bessel_J0(x);
        printf("J0(%g) = %.18e\n", x, y);
        return 0;
        }
        
        There is undefined reference error. But I can compile this
        without a
        problem:
        
        #include<stdio.h>
        #include<gsl/gsl_math.h>
        
        
        int main (void)
        {
        printf("%f\n", M_E);
        return 0;
        }
        
        Can anyone help me??
        Thanks
