[Help-gsl] Need help getting started!

[jgvicke]

Hey everyone,

It has been a while since I have needed to program in C, so I am a  
little rusty. I tried getting the basic test program working, but am  
recieving errors. This is the program I am trying to compile:

        #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;
        }

I am getting errors that say:

Error	1	error LNK2019: unresolved external symbol _gsl_sf_bessel_J0  
referenced in function _main

I think this is from the library not refrencing itself correctly. I  
have downloaded the entire library, then put everything in a folder  
called "gsl" in my compilers include directory. I even tried moving  
all the .h files into the main folder instead of leaving them in the  
many subdirectories, still with no luck. I am really stuck on how to  
move forward, and any help would be appreciated.

Thanks
