Compile and use PortAudio on OSX 10.7 (Lion)

November 10th, 2011 Leave a comment Go to comments

UPDATE: Version v19_20111121 doesn’t compile on my Lion, but version v19_20110326 does. I’ve updated this document accordingly.

UPDATE: Apparently, this also works on Snow Leopard. Not only that, but it might be the only way to use it under Snow Leopard.

It is frustrating to download the latest stable version of PortAudio, try to compile it on the new version of Mac OSX 10.7 (Lion), and get a bunch of errors.

However, for some reason, the previous stable release does work on 10.7.

Here the instructions (nothing fancy, just regular UNIX commands to compile and install):

  • Download the source file
  • Go to your directory and untar:
    $> tar zxvf pa_stable_v19_20110326.tgz
  • Configure:
    $> cd portaudio
    $> ./configure
  • Compile:
    $> make
  • Install:
    $> sudo make install

Now you should be able to go to the examples directory and compile and run the examples.

You must change the commas in #include "portaudio.h" for brackets: #include <portaudio.h>, so that the linker will look for the portaudio library inside your library path. To compile, for example paex_sine.c, you should type (inside the exmaples directory):

$> gcc -o paex_sine paex_sine.c -lportaudio

Then, you can just type ./paex_sine to listen to a 5 seconds sinewave.

If you are one of those who don’t like to install new libraries in your system path, you can always link with your libraries locally. In this case, you can leave the include with the commas. From the examples directory, you could compile some of these examples like this:

$> gcc -o paex_sine paex_sine.c -I../include/ -L../lib/.libs/ -lportaudio

In this case you will also need your DYLD_LIBRARY_PATH variable to point to your portaudio lib directory. Like this (it’s better to put the full path, I’m just putting the local path here as an example):

$> export DYLD_LIBRARY_PATH=../libs/.libs/

Now you can run it (from the examples directory): ./paex_sine

You’re all set.
Have fun coding with PortAudio!
