/*
*    Example program for the Allegro library, by Shawn Hargreaves.
*
*    This is a very simple program showing how to get into graphics
*    mode and draw text onto the screen.
*/


#include "allegro.h"



int main()
{
   /* you should always do this at the start of Allegro programs */
   if (allegro_init() != 0)
      return 1;

   /* set up the keyboard handler */
   install_keyboard();

   /* set a graphics mode sized 320x200 */
   if (set_gfx_mode(GFX_AUTODETECT, 320, 200, 0, 0) != 0) {
      if (set_gfx_mode(GFX_SAFE, 320, 200, 0, 0) != 0) {
         set_gfx_mode(GFX_TEXT, 0, 0, 0, 0);
         allegro_message("Unable to set any graphic mode\n%s\n", allegro_error);
         return 1;
      }
   }

   /* set the color palette */
   set_palette(desktop_palette);

   /* clear the screen to white */
   clear_to_color(screen, makecol(255, 255, 255));

   /* you don't need to do this, but on some platforms (eg. Windows) things
    * will be drawn more quickly if you always acquire the screen before
    * trying to draw onto it.
    */
   acquire_screen();

   /* write some text to the screen with black letters and transparent background */
   textout_centre_ex(screen, font, "Hello, world!", SCREEN_W/2, SCREEN_H/2, makecol(0,0,0), -1);

   /* you must always release bitmaps before calling any input functions */
   release_screen();

   /* wait for a keypress */
   readkey();

   return 0;
}

END_OF_MAIN();

这么一个程序 是allegro给的
在98下编译时能顺利通过   

而在dos下编译时出现
gcc -o hello.exe exhello.c -lalleg
in file include form g:/djgpp/include/allegro/base.h:25,
                  form g:/djgpp/include/allegro.h:25,
                  form exhello.c:9:
g:/djgpp/lib/gcc-lib//djgpp/3.1/include/limits.h:11:23: syslimits.h: no such file or director (ENOENT)

是怎么回事呀

晕  我知道了  是dos不支持长文件名的缘故
我加载了doslfn就可以了  ^_^
