[galib] Problem in linking GALib

[Tariq Saeed Ansari]

Hello,

     I am new to this list and I have downloaded GALib to use in my
Robotics project. I tried to compile a simple program using GALib but
I am getting a Linking error, although I have already defined the
correct paths for header files and library file(ga.lib). Following is
my program and linking errors that I am getting,

I don't understand what is the problem.

Note: I am using Visual C++ 2005 Express Addition

////// Program code

#include<iostream>

#include <ga/GASimpleGA.h>
#include <ga/GA2DBinStrGenome.h>

using namespace std;

float Objective( GAGenome& );

int main( void )
{
    GA2DBinaryStringGenome genome( 20, 10,Objective, (void*)0 );
}

float Objective( GAGenome& )
{
    return 0.0f;
}
