Pyaudio, portaudio and mac 10.7.5

Question

I'm having trouble installing pyaudio correctly. I have a virtualenv set up for the project. I first tried to install portaudio:

sudo port install portaudio

which returns:

--->  Cleaning portaudio
--->  Scanning binaries for linking errors: 100.0%
--->  No broken files found.

I assume that means it ran fine. Then I tried:

pip install pyaudio

Which returns:

Downloading/unpacking pyaudio
Running setup.py egg_info for package pyaudio

warning: no files found matching '*.c' under directory 'test'
Installing collected packages: pyaudio
Running setup.py install for pyaudio

src/_portaudiomodule.c:29:23: error: portaudio.h: No such file or directory
src/_portaudiomodule.c:33:25: error: pa_mac_core.h: No such file or directory
...

Is that first warning a problem? I'm a bit surprised it's saying no file or directory for portaudio.h. Do I have to do something special to enable my port audio macport installation?

Appreciate any help!

Answer 1

The problem is that the pyaudio setup script (setup.py) assumes that all the necessary headers are in /usr/include. That is why it works with HomeBrew, and not MacPorts, which typically (and cleanly) puts everything under /opt/local.

PyAudio maintainers have relied on HomeBrew, and there is no option combination right now that allows for spelling out where to find the headers. At time of writing, the setup.py source code supports only default values for Mac OS X.

To work with MacPorts, it is cumbersome but enough to create two links for compiling:

port install portaudio
sudo ln -s /opt/local/include/portaudio.h /usr/include
sudo ln -s /opt/local/include/pa_mac_core.h /usr/include
pip install --user pyaudio # Should now compile fine.

The links should probably be removed once the install is over.

Tested on Mac OS X 10.10 with Python 2.7 installed with MacPorts.

How about the following:

$ sudo port install py27-pyaudio

$ python -c "import pyaudio"

This works for me at least.
