Help needed with allegro installation.

[Sumeth]

Hello everyone,
I have been trying to get allegro 5 installed with codeblocks.
I have gotten to the point where when im typing code and wanting to reference to an allegro class, codeblocks will give suggestions to what it thinks I'm trying to reference to. For example :

This makes me think that i have done the installation partially correct?
Here are my linker settings:

I am using the MingW complier that was automatically installed with codeblocks. I am using codeblocks v12.11.
The problem i am receiving when compiling the following program:

 #include<allegro5/allegro.h>
#include<allegro5/allegro_native_dialog.h>

int main(int argc, char* argv)
{
	ALLEGRO_DISPLAY *display;

	if(al_init())
		al_show_native_message_box(NULL, NULL, NULL, "Could not initialize Allegro 5", NULL, NULL);

	display = al_create_display(800, 600);

	if(!display)
		al_show_native_message_box(NULL, NULL, NULL, "Could not create Allegro 5 display", NULL, NULL);


	al_destroy_display(display);

	return 0;
}

is :

Any ideas?
