Running asterisk?

I just finished from cross compiling asterisk for openrisc 1200 cpu of course without problems this time. But when I was trying to lanch asterisk in linux(built to run on this processor), this message shows up:

/bin/sh: asterisk: not found

of course when I took a look at asterisk direcotry there is asterisk binary file under /usr/sbin
and also when I tried to execute it like this
-cd /usr/sbin

the same message show up.

what do you think the problem is?

/usr/sbin isn’t on the shell path. That suggests you are trying to run it from a no-root account.
