Using allegro on QT, it crushes |

Hello everyone I have used allegro a couple of months ago on VisualStudio. So I'm somewhat new but I know a little about allegro. I'm doing an application on QT and I want to include Allegro to build an specific window. 1. I downloaded the files From Here. I downloaded the MSVC 11 one. 2. I copied the content on the respective folder (lib, include, bin). On my qt folder (C:\Qt\5.9\msvc2015\lib) 3. I added this lines to my .pro file changing depending on what librarys I use: Quote: LIBS += C:/Qt/5.9/msvc2015/lib/allegro-5.0.10-md.lib \
4. I ran some examples I found and all of them crush unless I make some changes. This example runs: 1#include <iostream>
2#include <allegro5/allegro.h>
3#include <allegro5/allegro_primitives.h>
4
5int main(){
6
7 if(!al_init()){
8 cout << "failed to dislpay" "Failed to initialize Allegro.\n"<< endl;
9 return -1;
10 }
11 al_init_primitives_addon();
12 ALLEGRO_DISPLAY *display = al_create_display(640,480);
13
14 if (!display){
15 cout << "failed to dislpay" << endl;
16 return -1;
17 }
18 al_clear_to_color(al_map_rgb(50,10,70));
19 //al_draw_triangle(10,10,20,10,15,50, al_map_rgb(255,0,0), 1.0);
20 al_flip_display();
21
22 al_rest(10.0);
23
24 al_destroy_display(display);
25
26 return 0;
27}
If I uncomment the line: Quote: al_draw_triangle(10,10,20,10,15,50, al_map_rgb(255,0,0), 1); The program stops working. The same happens with other lines like the ones related to font or drawing |

5.0.10 is old, and I'm pretty sure those binaries are not compatible with MSVC 2015. Go to http://liballeg.org/download.html#windows and download the Nuget package, or the binaries for MSVC 2015. 5.2 is much more recent, and probably fixes whatever bug you're hitting...

Thank you, it worked. It was a problem with the version as you said. I downloaded the binaries from the section "Allegro 5.2 binary packages" for MSVC. But it didn't have all the necesary files, only some. I made a proyect on Visual studio and downloaded the Nuget package for that proyect and copied the missing files from this proyect from the "packages" folder, it had a filder called Allegro.5.2.2.1. I changed the references from my .pro so it points to the files I copied from the proyect on visual studio: Quote:
LIBS += C:/Qt/5.9/msvc2015/lib/allegro.lib \ I leave what I did in case someone else has the same problem. By the way I didn't made the proyect on Visual Studio because I needed to add an interface for my QT proyect |
