You need to link to alleg.lib. In VC++2008 you can add #pragma comment (lib, "alleg.lib") to your source file along with your includes, or add it in the Linker->Input Project settings.

[headshake] ...

Why you shouldn't use Dev-C++.

Adding to Erik's suggestion, you can find the Linker options (in Visual Studio) under the project properties; just press Alt+F7, or go to "Project->project Properties..." from the menu bar.

i get 2 errors this time...

and this was because i added that line of code, so cool but i got to the linker input options but where do i add it and will it fix this error? because i was to get allegro working so i can start programming lol...


EDIT:
I got the linker to work lol but i am still getting the same 2 errors!


#include <allegro.h>


int main()
{
allegro_init();
install_keyboard();
set_gfx_mode(GFX_AUTODETECT, 640, 480, 0, 0);

acquire_screen();

release_screen();

readkey();
return 0;
}
END_OF_MAIN();

It seems you have created a console project. You need to either create a Windows project, or use #define ALLEGRO_USE_CONSOLE before including allegro.h, if you want a console window.
I would also recommend using GFX_AUTODETECT_WINDOWED for set_gfx_mode, so you don't have to switch screen resolutions every time you run it.

OMFG THANK YOU! lol just like to say thanks to everyone here at this site for the quick response's and for sticking by my side ^_^ i almost cried lol jking but still thanks for the help guys hopefully when i get better at programming you will all see my name in a good game ^_^
