Question

I am running Enthought Python 2.7 as well as default Python 2.7, Xcode 4.5.1 in Mac OS 10.8.2. I am trying to develop a speech to text converter in Python. I use Enthought Python as it allows me to record in 16000Hz, 1 Channel using pyaudio, which is needed for pocketsphinx to work.

I am trying to setup pocketsphinx using brew install pocketsphinx.

I get the following errors

Even manual installation using make and using default python results in same errors

Using brew doctor, I get

How do I successfully install pocketsphinx?

Here is my config.log

Homebrew logs pocketsphinx, sphinxbase

According to the log you have outdated version of the libsndfile installed. You have a header sndfile.h, but not sndfile.pc pkg-config file:

configure:14532: checking for SNDFILE
configure:14540: $PKG_CONFIG --exists --print-errors "sndfile"
Package sndfile was not found in the pkg-config search path.
Perhaps you should add the directory containing `sndfile.pc'
to the PKG_CONFIG_PATH environment variable
No package 'sndfile' found
configure:14543: $? = 1
configure:14558: $PKG_CONFIG --exists --print-errors "sndfile"
Package sndfile was not found in the pkg-config search path.
Perhaps you should add the directory containing `sndfile.pc'
to the PKG_CONFIG_PATH environment variable
No package 'sndfile' found
configure:14561: $? = 1
No package 'sndfile' found
configure:14589: result: no
configure:14603: checking sndfile.h usability
configure:14603: gcc -std=gnu99 -c -g -O2 -Wall  -
I/Library/Frameworks/Python.framework/Versions/7.3/include/python2.7 -
I/Library/Frameworks/Python.framework/Versions/7.3/include/python2.7 conftest.c >&5
configure:14603: $? = 0
configure:14603: result: yes

To solve this problem either remove the header to not confuse the configure or install newer sndfile with pkg-config support.

Actually that should be fixed in sphinxbase as well, a bug report would be welcome.
