Subject: Cross building udev cannot creat device node
Date: Tue, 03 Jun 2014 03:05:08 +0000 [thread overview]
Message-ID: <CADVuKbpPPj_8O8wu1tAsfPztdv0ipPy03FKNZgnDd75f6n3cLA@mail.gmail.com> (raw)
I cross build Udev and run on arm and found cannot creat device node.

(Freescale MAD -- Linaro 2011.07 -- Built at 2011/08/10 09:20) ) #161
