Re: [Vserver] anybody has experience for Vserver on ARM
yes, i got the warning message while compile vcmd:
[EMAIL PROTECTED] vcmd-0.08]# make
arm-angstrom-linux-gnueabi-gcc -g -Wall -O2 -Ivserver -o vcmd vcmd.c
In file included from vserver.h:4,
from vcmd.c:34:
syscall.h:110:2: warning: #warning syscall arch arm not tested yet
.
Seems the syscall does not tested on ARM. Anybody make vserver successfully
on ARM? Thank you so much!
Thanks,
Wenbin

well, the syscall trap looks fine, 313 is the syscall
on arm and it seems that util-vserver uses the same
implementation, so that should be fine too ...
you might get a warning at compile time, if that would
be interesting to have, otherwise something with your
toolchain could be wrong ...
