Did some reading, it seems to me the problem is this part of the header:

Code:

#ifndef GNURANDOM
#ifdef __GNUG__
#pragma interface
#else
typedef int _G_int32_t ;   //This is the problem line
#endif
#define GNURANDOM

#include <math.h>
#ifdef __linux
#include <_G_config.h>
#else
#include "random/GnuTypes.h"
#include "random/GnuRandom.h"
#endif
#include "system/Assert.h"

which probably is NOT standard unsigned integer type.
The #ifdef/ifndef and #pragma make me confused with my OS Linux HP32 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux I conceptually understand #ifdef/#ifndef, and #pragma, but not sure under my present OS whether they are defined or not. How should I fix this? Thanks a lot!

request_scroll

request_scroll(3alleg4) 					  Allegro manual					   request_scroll(3alleg4)

NAME

       request_scroll - Queues a hardware scroll request with triple buffering. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       int request_scroll(int x, int y);

DESCRIPTION

       This  function  is  used for triple buffering. It requests a hardware scroll to the specified position, but returns immediately rather than
       waiting for a retrace. The scroll will then take place during the next vertical retrace, but you can carry on running  other  code  in  the
       meantime and use the poll_scroll() routine to detect when the flip has actually taken place.

       Triple  buffering  is only possible with certain drivers: you can look at the GFX_CAN_TRIPLE_BUFFER bit in the gfx_capabilities flag to see
       if it will work with the current driver.

RETURN VALUE

       This function returns zero on success, non-zero otherwise.
