error when trying the preset with x264

[msm_007]

Hi all,
I’ve tried to encode raw video with x264, with different preset (http://mewiki.project357.com/wiki/X264_Settings), I’ve found a several error like
unrecognized option '--rc-lookahead'
unrecognized option '-- no-mixed-refs '
…
do you have idea, plz, from where I get this error?
I work with x264 under linux

Your x264 is too old. Update to the latest version.

Build it yourself.

Install git, GCC, yasm, make and libc headers. For example on Ubuntu:
sudo apt-get install git-core build-essential yasm

Fetch the latest x264 source code tree. (When updating later, just run "git pull" in the x264 directory and recompile):
git clone git://git.videolan.org/x264.git

Compile:
cd x264
./configure
make

Optionally, install to /usr/local:
sudo make install
