    Allegro Help

    Im starting to get further into coding, and now I need help with Allegro.

    Im following a tutorial to it, but when I try to compile the program, it runs this error:
    Compiler: Default compiler
    Building Makefile: "C:\Documents and Settings\Dan\Desktop\Site\Programming\Allegro\Make"
    Executing make...
    make.exe -f "C:\Documents and Settings\Dan\Desktop\Site\Programming\Allegro\Make" all
    g++.exe -c main.cpp -o main.o -I"C:/Dev-Cpp/include/c++" -I"C:/Dev-Cpp/include/c++/mingw32" -I"C:/Dev-Cpp/include/c++/backward" -I"C:/Dev-Cpp/include"

    windres.exe -i Allegro_Test_private.rc -I rc -o Allegro_Test_private.res -O coff

    main.o(.text+0xc4):main.cpp: undefined reference to `_imp__key'
    main.o(.text+0xdd):main.cpp: undefined reference to `_imp__key'

    make.exe: *** ["Allegro] Error 1

    Execution terminated
    Heres the code, seems right according to the tutorial.
    #include <allegro.h>
    int initAlleg() {
        set_color_depth(8); //set color to 8 bit
        allegro_init(); //initiate allegro
        install_keyboard(); //initiate keyboard
        if (set_gfx_mode(GFX_AUTODETECT, 800, 600, 0, 0) < 0) {
            allegro_message("Error setting screen resolution.\n%s\n", allegro_error);
            return -1;
        return 0;
    int main() {
        if(initAlleg() < 0) {
            while(! key[KEY_ENTER])
            return 0;
        while(! key[KEY_ENTER])
        return 0;

    Add #define ALLEGRO_STATICLINK to the top of your code.
