Specify a path for ctypes.util.find_library() under macOS

Create Python C extension using MacOS 10.15 (Catalina) that is backwards compatible (MacOS10.9+)

QUESTION

Specify a path for ctypes.util.find_library() under macOS

Asked 2020-Sep-12 at 01:00

I'd like to specify a path for ctypes.util.find_library() to search. How can I do this?

I'd like to do it from within Python.

I'm using macOS.

If I wanted to do it from outside Python, I can specify the location using LD_LIBRARY_PATH. However I have read that I cannot modify this environment variable from within Python as it is cached on Python's startup. Modifying the value and then restarting Python seems like a very unusable idea; for example, what would happen if the library was imported part way through execution?

Why would I like to do this? Because I would like to add a MacOS wheel to a Python library that works under Windows. Currently they're packaging the DLLs into the same directory as the Python source files and adding that path to Windows' PATH environment, which ctypes.util.find_library() searches--a technique that I can't seem to replicate under Mac.

I have tried to understand delocate. It seems to state that the Python library doesn't depend on any shared objects. I suspect this is because the dylibs are loaded dynamically using ctypes.util.find_library() rather than being compiled code within Python.

Any suggestions would be gratefully received!

Although there are environment variables (LD_LIBRARY_PATH and DYLD_LIBRARY_PATH) that impact the search path for shared libraries, they are read and fixed by Python when Python starts up. Thus that option was eliminated.

Instead, we took the approach hinted at in the Python documentation:

If wrapping a shared library with ctypes, it may be better to determine the shared library name at development time, and hardcode that into the wrapper module instead of using find_library() to locate the library at runtime.

We hard-coded the names of the libraries that were included for each operating system, plus we included a generic name for operating systems where the libraries were not included:

I found the solution to my problem and I will post the answer here in case someone else has the same problem.

In order to fix the problem I had to also set export MACOSX_DEPLOYMENT_TARGET=10.9 before I install python using pyenv. Now pip wheel creates my wheel with the tag macosx_10_9_x86_64.

Thank you.

PS: When installing python via pyenv, python is compiled from source, and somehow it takes into account the flag MACOSX_DEPLOYMENT_TARGET.

Vulnerabilities

No vulnerabilities reported

Install delocate

You can install using 'pip install delocate' or download it from GitHub, PyPI.
You can use delocate like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
