hello!
I'm porting directfb to my uclinux arm7 box, when I
run df_cpuload, it can run for only 1 or 2 second, and
the get the message:
(!) DirectFB/Config 'tmpfs': No directory specified!
(!) [ 30: 2.730] --> Caught signal 4 (at 0x2f706d80, illegal trap) <--
then exit!
I'm using single core, I'm not sure why it need tmpfs,
how to solve it?
