The next step is to compile and install the necessary libraries.

1. Open a Terminal window. Enter the following commands, shown in bold.
   
   
2. cd /Applications/Transana_2/transana_ffmpeg
   
   
3. Install LAME:
   
   cd lame-3.96.1
   
   ./configure --prefix=/Applications/Transana_2/transana_libs --disable-shared --enable-static
   
   make
   
   make install
   
   cd ..
   
   
4. Install zlib:
   
   cd zlib-1.2.3/
   
   ./configure --prefix=/Applications/Transana_2/transana_libs
   
   make
   
   make install
   
   cd ..
   
   
5. Install faad:
   
   cd faad2-20050513
   
   ./configure --prefix=/Applications/Transana_2/transana_libs
   
   cd libfaad
   
   If you are on an Intel-based Mac, you need to open the file "common.h" and edit the file. When you run Make, you will get an error message giving you the line number (for me it was 361) telling you where to edit. Comment out the second definition for lrintf, in the #elif clause.
   
   make
   
   make install
   
   cd ../..
   
   
6. Install x264:
   
   cd x264-snapshot-20060822-2245
   
   ./configure --prefix=/Applications/Transana_2/transana_libs
   
   make
   
   make install
   
   cd ..
   
   
7. Install ffmpeg:
   
   cd ffmpeg
   
   ./configure --prefix=/Applications/Transana_2/transana_libs --enable-faad --enable-mp3lame --enable-x264 --enable-gpl --extra-cflags=-I/Applications/Transana_2/transana_libs/include --extra-ldflags=-L/Applications/Transana_2/transana_libs/lib
   
   make
   
   ./makeaudioextract
   
   If you are on an Intel-based Mac, you may get an error message saying that makeaudioextract can't find LAME. If so, edit makeaudioextract, adding "-L/Applications/Transana_2/transana_libs/lib" in front of the "-lmp3lame" parameter.
   
   cd ..

There should now be an executable file named "audioextract" in the /Applications/Transana_2/ffmpeg directory.   Copy that file to your Transana source directory. If you plan to build an application bundle, you will also need to make a copy of it named "audioextract PPC" or "audioextract Intel", depending on your processor type.
