Question

我成功编译了Directfb，现在当我运行Directfb的任何示例或任何应用程序时，我收到此错误：

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

有什么想法吗？

Answer 1

我解决了这个问题：

以root身份登录。
在运行您的应用程序时使用--dfb:system=FBDev。例如./myapplication --dfb:system=FBDev

将以下内容添加到.directfbrc：

system=fbdev
fbdev=/dev/fb0

Directfb未实现的错误
