Trouble installing on osx "fatal error: 'al.h' file not found"

[RawStewage]

Hi I've been trying for some time to figure out how to install this on OSX but when I run pip3 install pocketsphinx I get the following error log:

Any help or advice would be greatly appreciated

[zsiegel92]

I have the same problem!

[CharushS]

Please try the following steps

1. git clone --recursive https://github.com/bambocher/pocketsphinx-python
2. cd pocketsphinx-python
3. Edit file pocketsphinx-python/deps/sphinxbase/src/libsphinxad/ad_openal.c
4. Change

#include <al.h>
#include <alc.h>

to

#include <OpenAL/al.h>
#include <OpenAL/alc.h>

5. python setup.py install

[bambocher]

Should now work with pip3 install pocketsphinx.

[nachtgold]

I got the same error with version 0.1.15 on High Sierra.

[tysonjwang]

Make sure you do brew install swig

[nachtgold]

Swig was installed, but al.h and alc.h were also grouped by OpenAL on my mac. And that is not covered in 0.1.15 or I didn't see how. So I patched the file like @CharushS mentioned it.

[poioit]

HI nachtgold ,
I have the same problem with you.
after I do
sudo port install swig-python.
And I follow CharushS's step. It works.

[EralpB]

not working.

[dev-michael-schmidt]

Has anybody looked at creating a fix for this?

Please try the following steps

1. git clone --recursive https://github.com/bambocher/pocketsphinx-python
2. cd pocketsphinx-python
3. Edit file pocketsphinx-python/deps/sphinxbase/src/libsphinxad/ad_openal.c
4. Change

#include <al.h>
#include <alc.h>

to

#include <OpenAL/al.h>
#include <OpenAL/alc.h>

1. python setup.py install

@CharushS where should this be cloned to? Some location within usr/local/lib so that it loads into the path?

[nachtgold]

My copy is located in /Users/%me%/projects, but I hope it doesn't matter (MacOS 10.14.1).

[CharushS]

@iyoob @nachtgold cloning location doesn't really matter
