Hi there,
I am trying to statically link Allegro 5 using pkg-config in Ubuntu. I have been using the following example program as a test:
1#include <iostream>
2
3#include <allegro5/allegro.h>
4#include <allegro5/allegro_image.h>
5#include <allegro5/allegro_primitives.h>
6
7using std::cout;
8
9int main(void) {
10
11 if (!al_init()) {
12
13 cout << "Error: failed to initialize Allegro 5.\n";
14
15 return -1;
16 }
17
18 if (!al_init_image_addon()) {
19
20 cout << "Error: failed to initialize image addon.\n";
21
22 return -1;
23 }
24
25 if (!al_init_primitives_addon()) {
26
27 cout << "Error: failed to initialize primitives addon.\n";
28
29 return -1;
30 }
31
32 if (!al_install_keyboard()) {
33
34 cout << "Error: failed to install keyboard.\n";
35
36 return -1;
37 }
38
39 ALLEGRO_TIMER *timer = al_create_timer(1.0 / 60.0);
40 ALLEGRO_DISPLAY *display = al_create_display(800, 600);
41 ALLEGRO_EVENT_QUEUE *event_queue = al_create_event_queue();
42
43 ALLEGRO_EVENT event;
44
45 al_register_event_source(event_queue, al_get_keyboard_event_source());
46 al_register_event_source(event_queue, al_get_timer_event_source(timer));
47 al_register_event_source(event_queue, al_get_display_event_source(display));
48
49 al_start_timer(timer);
50
51 bool render = true;
52 bool running = true;
53
54 unsigned int r = 0;
55 unsigned int g = 0;
56 unsigned int b = 0;
57
58 unsigned int ticks = 60;
59
60 while (running) {
61
62 al_wait_for_event(event_queue, &event);
63
64 if (event.type == ALLEGRO_EVENT_KEY_DOWN) {
65
66 if (event.keyboard.keycode == ALLEGRO_KEY_ESCAPE) {
67
68 // End the game.
69 running = false;
70 }
71 }
72 else if (event.type == ALLEGRO_EVENT_TIMER) {
73
74 render = true;
75
76 ++ticks;
77
78 if (ticks >= 30) {
79
80 // Generate new color twice per second.
81
82 r = rand() % 255;
83 g = rand() % 255;
84 b = rand() % 255;
85
86 ticks = 0;
87 }
88 }
89
90 if (render && al_is_event_queue_empty(event_queue)) {
91
92 render = false;
93
94 // Clear to red.
95 al_clear_to_color(al_map_rgb(255, 0, 0));
96
97 al_draw_filled_rectangle(80, 80, 160, 160, al_map_rgb(r, g, b));
98
99 al_flip_display();
100 }
101 }
102
103 al_destroy_timer(timer);
104 al_destroy_display(display);
105 al_destroy_event_queue(event_queue);
106
107 return 0;
108}
Here is the command I use to compile it (not statically):
g++ -Wall -o example example.cpp $(pkg-config --libs allegro-5 allegro_image-5 allegro_primitives-5)
du -h example returns 16K as the file size. Now when I try to compile it with static libraries:
g++ -Wall -o example example.cpp $(pkg-config --libs --static allegro-5 allegro_image-5 allegro_primitives-5)
And du -h example still returns 16K as the file size! 
Shouldn't the file size be considerably larger when statically compiled? Because the file size doesn't change, this leads me to believe that something isn't right. Is there something I'm supposed to do when making Allegro to make sure I can link it statically? 
Thanks in advance!
