Allegro 5 al_init problem

I'm new to allegro and I'm trying to run this simple code

#SelectExpand
  1#include 
  2#include 
  3#include 
  4
  5int main(void)
  6{
  7  ALLEGRO_DISPLAY *display;
  8
  9  if( !al_init() )
 10  {
 11    al_show_native_message_box( NULL, NULL, "Error", "Couldnt initialize Allegro 5", NULL, ALLEGRO_MESSAGEBOX_ERROR );
 12    return -1;
 13  }
 14
 15  display = al_create_display( 800, 600 );
 16
 17  if( !display )
 18  {
 19    al_show_native_message_box( display, " Sample Title", "Display Settings", "Display window unable to display", NULL, ALLEGRO_MESSAGEBOX_ERROR );
 20  }
 21
 22  al_show_native_message_box( display, "Message box title", "Error", "Display window could not be shown", NULL, ALLEGRO_MESSAGEBOX_ERROR );
 23
 24  al_destroy_display( display );
 25
 26  return 0;
 27}

Every time I run it I get the "Couldnt initialize Allegro 5" message box instead of "Display window could not be shown". I tried code similar to mine( as in !al_init returning true ) and i get the same problem.

Any help will be greatly appreciated.

Did you by any chance mix up any previous installation of Allegro with the current one? This may happen if you have headers from a different version of the library installed than the library itself was built with.

Yes, he did. I'll put 50 cents toward your next game if I am wrong.

#include 
#include 

int main()
{
  printf("%0x\n%0x\n", ALLEGRO_VERSION_INT, al_get_allegro_version());
  return 0;
}

That means you are compiling against Allegro 5.1 headers, but are linking against Allegro 5.0.

You could delete the 5.0 libraries from /usr/local/lib, although depending on what you've done to get to this point, there may be something else going on.
