Ubuntu 10.10 64 bit

Original issue reported on code.google.com by s.scrip...@gmail.com on 26 Oct 2010 at 10:22

the original hustoj is designed on 32bits system and for 32bits system only.
i never got a chance to try hustoj on a 64bits system.
so far i can tell is just making a guess.
64bits system has difference on syscalls, because hustoj is judging abnormal 
operation based on sys-calls, these differences can cause compiling error.

you can check these apis ,find the replacement in 64bits.
or just comment out all related code in judge_client.cc
that should go through make and working
but you'll lost corresponding safety assurance

i'll try to find a 64bits system to help this issue out.

compile an A+B sample solution to main.

strace ./main 2>&1|awk -F\( '{print $1}'|sort -u

will help you to determine which syscalls is needed on the system.

replace them into the okcalls.h

that should helps you port HUSTOJ on 64bits system.

The easyest way to solve the problem:
Comment lines 821-831(the if-else block)

Ps:these lines are the security mode,so you should be aware of the affereffect 
before u take action

johnnychq's suggestion is not recommanded for productive system.
and you also have to delete associated SYS_xxxx in okcalls.h.

anyone have 64bit's system can make his own okcalls.h with some test of strace 
-c .

a patch of this issue is welcomed.

thanks to johnnychq's ssh on 64bits VM.
r520 is the beta version of 64bits support
