Revision 1.5
- libimf.so and libimf.a notes

Revision 1.4
- static linking
- compiler optimizations

Revision 1.3
- added Intel links
- fixed patch command
- added notes about build dependencies

Step 1a
-------
Download the code from Intel

cd /tmp
wget ftp://download.intel.com/software/products/ipp/downloads/samples/l_ipp-sample-speech-coding_p_4.1.008.tgz
wget ftp://download.intel.com/software/products/ipp/downloads/l_ipp_ia32_itanium_p_4_1.tar

Step 1b
-------

Install Asterisk header files

On Debian, just type

  apt-get build-dep asterisk

Specifically, you need the *.h files that come with Asterisk

Step 2a
-------

Register with Intel

See http://www.intel.com/software/products/ipp/

a) register on Intel's site under the 'free non-commercial use' section
b) obtain the license number and a license key file
c) put the license key file in the place specified by Intel's documentation
d) run the installer

Step 2b
-------

Install IPP libraries.

mkdir /tmp/ipp-tmp
cd /tmp/ipp-tmp
tar xf /tmp/l_ipp_ia32_itanium_p_4_1.tar

Follow Intel's instructions to install IPP.  If using Debian, the Intel
installed will stop half way, leaving a .rpm file sitting in a subdirectory
of /tmp.  You can install the .rpm file using `alien' and then proceed.

Intel's instructions and licensing information (including Open Source
version information) are at http://www.intel.com/software/products/ipp/

Once you've installed IPP and agreed to the license terms, you may need to
copy the libraries from one PC to another (eg, from your development machine
to a production server).  You just need to copy the contents of the following
directory:

/opt/intel/ipp41/ia32_itanium/sharedlib/

without re-running the install process.

If you use static linking, you DON'T need to copy the libraries onto
every computer where you run the codec.  You only need the libraries
on the computer where you compile the codec.

Step 3
------

Install IPP sample code

cd /usr/local/src
tar xzf /tmp/l_ipp-sample-speech-coding_p_4.1.008.tgz

Step 4
------

Apply my patch

cd intel1/ipp_sample/speech-coding/G729-float/
patch -p1 < /tmp/g729-041103.diff

Step 4a
-------

Select compiler optimizations

vi Makefile

Step 5a
-------

If you have icc 8.0 libimf, move intel_cc_80/lib/libimf.so to 
somewhere out of the way.  This will allow you to link libimf.a
statically with codec_g729.so

Step 5b
-------

Build

./build.sh

Step 6
------

Deploy

cp bin/codec_g729.so /usr/lib/asterisk/modules   (this location depends
							on your system)

If you haven't used static linking (now the default),
modify /etc/init.d/asterisk:

export LD_LIBRARY_PATH=/opt/intel/ipp41/ia32_itanium/sharedlib:/opt/intel/ipp41/ia32_itanium/sharedlib/linux32:$LD_LIBRARY_PATH

You may need to insert the following into your sip.conf:

allow=g729

Now restart Asterisk

/etc/init.d/asterisk restart

Step 7
------

Verify install

At the shell prompt:
# asterisk -r

At the Asterisk prompt:
>show translation

If the G.729 column has -'s instead of numbers, then the codec is not
working properly.
