I'm in trouble with this: I've installed Allegro5 on Ubuntu, and compiled my Helloworld project

#include <allegro5\allegro.h> #include <allegro5\allegro_native_dialog.h> int main(void) {
ALLEGRO_DISPLAY *display=NULL;
if(!al_init()) {
al_show_native_message_box(NULL, NULL, NULL, "failed to initialize allegro!", NULL, NULL);
return -1;
}
display=al_create_display(640,
480);
if(!display) {
al_show_native_message_box(NULL, NULL, NULL, "failed to initialize display!", NULL, NULL);
return -1;
}
al_destroy_display(display);
return 0;
}

with " g++ -Wall TestProgram.cc pkg-config --libs allegro-5.0 allegro_font-5.0 allegro_ttf-5.0 ". Running it on terminal, it gives me this error (or crash?) message:

nac@NAC:~$ ./a.out
nouveau: kernel rejected pushbuf: Bad file descriptor
nouveau: ch0: krec 0 pushes 1 bufs 1 relocs 0
nouveau: ch0: buf 00000000 00000002 00000004 00000004 00000000

nouveau: 0x20217000
nouveau: 0x00000003
nouveau: 0x1000f010
After some tests I saw that it crashes on or after "al_destroy_display(display);", in fact, after that error I must ctrl+C to end the program.

How can I do??:'(

Try updating your graphics driver as this lists it in a bug:

https://bugs.freedesktop.org/show_bug.cgi?id=79823

Don't forget to use <code > tags.

Also, do any of the allegro examples fail?

[edit]

Wait, are you specifying -o anywhere in gcc?

ala "gcc mygame.cc -o mygame"

Because you might be running an object file, and not an executable.

You need backticks around the pkg-config call, as it is a separate command that returns the necessary information to compile your program.

GCC defaults to an elf executable filename of "a.out" if you don't specify a filename.
