 ==== Build the IPP samples ====
+ 1. Open Terminal application
  1. Go to the directory where IPP samples have been extracted to (e.g. {{{~/Desktop/ipp-samples}}}).
  1. Go to {{{speech-codecs}}} folder.
  1. Open the {{{readme.htm}}} file, and follow the instructions there to build the samples from the source.

+ 1. '''Important:''' since Intel C Compiler (icc) is installed, specify argument '''{{{gcc4}}}''' when executing the '''{{{build*.sh}}}''', to build the samples with GCC compiler. Without this, the samples will be built with icc and it will result in link error when compiling PJSIP applications with gcc.
+ 1. Sample command to build the samples:
+ {{{
+$ cd ~/Desktop/ipp-samples/speech-codecs
+$ export IPPROOT=/Library/Frameworks/Intel_IPP.framework/Versions/Current/
+$ ./buildem64t.sh gcc4
+ }}}

 The build process produces the following:
- - (for IPP v6.x) '''{{{libspeech.a}}}''' file somewhere under {{{speech-codecs/_bin}}} directory, e.g. {{{ipp-samples/speech-codecs/_bin/osxem64t_icc111/lib}}} directory.

+The directory name may be different, depending on which target architecture is selected to be build.
 
 If you have any problems with installing and/or building the IPP or IPP samples, please read the IPP documentation or contact Intel for support.

 For this tutorial, we'll use two environment variables to hold the location of IPP and IPP samples.

 Note that you still need to enable IPP support in your {{{config_site.h}}} in order to use the IPP features. This will be explained in the next section.
