/* * 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 ^_^
