building issues on macOS

[shakfu]

On macOS, /usr/local/include and /usr/local/lib are not automatically searched so pip install sox bindings fails.

I have fixed this by git cloning the soxbindings repo and making the following changes to the setup.py file:

% git diff setup.py
diff --git a/setup.py b/setup.py
index 3ee9d8c..8b2c894 100644
--- a/setup.py

The issue was that pip install soxbindings returns the following error:

After cloning the repo and making the above changes the following needs to be run (from the folder where the repo was cloned):

python setup.py install

For me, since I installed sox with homebrew, I had to change the folders to make it work:

ext_modules = [
    Extension(
        'soxbindings._soxbindings',
        # Sort input source files to ensure bit-for-bit reproducible builds
        # (https://github.com/pybind/python_example/pull/53)
        sorted(['soxbindings/ext/sox.cpp']),
        include_dirs=[
            # Path to pybind11 headers
            get_pybind_include(),
            "/opt/homebrew/include/",
        ],
        library_dirs=[
            "/opt/homebrew/lib/",
        ],
        language='c++'
    ),
]

After, I can run successfully (inside the cloned repo folder):

pip install -e . 

Since this is a very configuration specific change, I don't know how to create PR to fix it 🤷

This might be interesting for readers of pytorch/audio#53

I think you can generalize the solution to the following if you have installed sox using homebrew:

import subprocess 
# ...
SOX_PREFIX = subprocess.check_output(['brew', '--prefix', 'sox'], encoding='utf8').strip()
#...
ext_modules = [
    Extension(
        'soxbindings._soxbindings',
        # Sort input source files to ensure bit-for-bit reproducible builds
        # (https://github.com/pybind/python_example/pull/53)
        sorted(['soxbindings/ext/sox.cpp']),
        include_dirs=[
            # Path to pybind11 headers
            get_pybind_include(),
            f"{SOX_PREFIX}/include",
        ],
        library_dirs=[
            f"{SOX_PREFIX}/lib",
        ],
        language='c++'
    ),
]
