Practical primer for and others arriving here later:

Decide which Allegro major version to target up front — legacy 4.x and modern 5.x are not API-compatible. After picking a version, verify the development package for the chosen toolchain (GCC/Clang/MSVC) is installed, then confirm a minimal program builds and runs before adding features. Work incrementally: get a window, then draw, then input, then timers/audio.

A smallest Allegro 5 example to verify setup:

#include <allegro5/allegro.h>

int main() {
    if (!al_init()) return -1;
    ALLEGRO_DISPLAY *d = al_create_display(800, 600);
    if (!d) return -1;
    al_clear_to_color(al_map_rgb(0,0,0));
    al_flip_display();
    al_rest(1.5);
    al_destroy_display(d);
    return 0;
}

Example build (Linux with pkg-config):

g++ -std=c++11 main.cpp -o app `pkg-config --cflags --libs allegro-5 allegro_image-5 allegro_font-5`

Troubleshooting checklist

  • Header not found: set include paths to the Allegro dev headers.
  • Linker errors: add the core library and any addons used (image, font, ttf, audio, primitives).
  • Runtime crashes: confirm 32/64-bit build matches the Allegro binaries and runtime.
  • Initialization fails: check return values (al_init, al_create_display, addon inits) and enable simple logging.
  • For event-driven code, prefer an event loop with timers rather than busy-waiting.

Suggested learning path

  1. Display creation and basic drawing. 2) Event queue, timers, keyboard/mouse. 3) Bitmaps, sprites, and simple collision. 4) Fonts, text, and UI. 5) Audio and packaging assets. Build tiny projects (moving sprite, menu, simple platform) to practice.

Note: ’s birthdate/zodiac request is off-topic for Allegro — it’s a straightforward console C++ task (parse a date, map ranges to signs/birthstones); recommend a new thread focused on that.

Sorry, i did know what i did there, (clearly the wrong thing), anyway i made this thread because i would like to know the best way to learn the Allegro Libary for C++.

I can use C++ very well, its just the Allegro that i don't get.

Any help would be appreciated, thanks.
