These are not real errors, these are WARNING. You are passing a float where the function wait an int.

cars.cpp:17: warning: passing `float' for converting 3 of `void rotate_sprite(BITMAP*, BITMAP*, int, int, fixed)'

The others are not allegro related, but these are real errors.

You are using a third party library which you are not linking against. Looks like you need to link this "taste desenar" library, who is using the functions you do not know.

Gull, "multiple definitions" isn't the same as "undefined reference"... If fact, it's the opposite

It has nothing to do with Allegro. You are #including cpp files. Stop it.

You know how to create a header file? Do that, then #include the header file.

Arf :p My eyes were aimed by the bolded text who said "first defined here" :p

I did copy paste the code but without noticing the multiple definition ;-)

Anyway his problem is now solved.

But ... Hey ! Wait ! Adix88 , You are a cookie scrooge, aren't you ? !
