directFB 在编译的时候没有错误，接下来编译它所带的例子，编译能通过，运行不了程序

运行的时候老报这个错误，然后程序就自动退出运行了，
printf("--------------screen_width=%d\n",screen_width);
ret = dfb->CreateImageProvider(dfb,"/desktop.png",&provider);
if(ret)
{
printf("image create fail\n");
}
printf("--------------screen_width=%d\n",screen_width);
创建的时候创建失败了。为什么，
