Doesn't run in vscode on linux mint

[Shadowblitz16]

I followed the information on the wiki repo and I am getting undefined reference errors everywhere

this is what my code looks like..

#include <iostream>
#include <allegro5/allegro.h>
#include <allegro5/allegro_font.h>
#include <allegro5/allegro_ttf.h>

int main()
{
    al_init();

    al_init_ttf_addon();

    ALLEGRO_DISPLAY* display = al_create_display(512,480);
    ALLEGRO_FONT   * font    = al_load_ttf_font("assets/pico8.ttf", 64, 0);

    std::cout << (font == nullptr) << std::endl;

    while (true)
    {

    }

    al_destroy_display(display);
    al_destroy_font(font);
    return 0;

You need to tell g++ to link in the Allegro libraries.

What wiki page were you following? If it tells you to compile like that, it's bad advice.

[Shadowblitz16]

@pedro-w I was following YouTube tutorials. also I was using vs code's runner plugin.

I moved to windows and got it working.

I still have no idea how to actually run it from vs code.

@Shadowblitz16 : To consult doubts or problems, you can visit the Allegro forum:

https://www.allegro.cc/forums/board/programming

EDIT: You must also say the links of the tutorials, guides or wiki that you followed.

I've made some notes on this but I haven't typed them up yet

@Shadowblitz16 I've done this https://github.com/liballeg/allegro_wiki/wiki/Using-Visual-Studio-Code Still a WIP so I haven't linked it to the main content of the wiki. What do you think?

[Shadowblitz16]

I don't know everytime I try c or c++ I run into a enormous amount of issues..

• ide's and text editors not working
• the requirement of make files
• compiler errors that don't maker sense.

I think me staying away from c and c++ is probably a good thing. however I hope that this issue I raised will help someone else

It's like riding a bike. Here is not the place for discussion, though, why not go to allegro.cc and people will help you.
