Directfb未实现错误

Question

我成功地编译了Directfb，现在当我运行Directfb的任何示例或任何应用程序时，我都会收到这个错误：

(!!!)  *** UNIMPLEMENTED [fusion_dispatch] *** [fusion.c:3937]

有什么想法吗？

Answer 1

我通过以下方式解决了这个问题：

1. 以超级用户身份登录。
2. 在运行应用程序时使用--dfb:system=FBDev。例如./myapplication --dfb:system=FBDev

Answer 2

我在qingy上也遇到了同样的问题。更多详细信息：

将以下内容添加到您的.directfbrc：

system=fbdev
fbdev=/dev/fb0
