伙计们，我正在尝试在 Ubuntu 11.04 上安装 allegro 5 库。我遵循的教程是这样的。现在我在第一次尝试安装库时遇到了一些错误，但我可以克服它们并正确安装库。问题是当我尝试运行我的示例代码时
#include <allegro5/allegro.h>
int main(int argc, char *argv[])
{
allegro_init();
install_keyboard();
set_gfx_mode(GFX_AUTODETECT, 640,480,0,0);
readkey();
return 0;
}
END_OF_MAIN()
我收到类似的错误

我有所有的主要头文件/usr/include/allegro5。
