New submission from Carlton Gibson <carlton.gibson at noumenal.es>:
On MacOS 11.3 "Big Sur", with the latest 3.9.4 installed with the official installer downloaded from python.org, the DYLD_LIBRARY_PATH environment variable is not being respected.
This looks very similar to Issue40198
To begin everything looks correct as per 40198:
~ $ python3 --version
~ $ which python3
~ $ codesign --display --entitlements=:- /Library/Frameworks/Python.framework/Versions/3.9/bin/python3
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
The active python is that from the official installer, and it looks to have the correct entitlements, as per the resolution to 40198.
However, it's not working in practice.
I create a script test:
~ $ cat ~/bin/sqlite_config.py
Together with a compiled SQLite version:
~ $ ls /Users/carlton/lib/sqlite/3.35.4
Trying to use this, the dylib is not picked up:
~ $ DYLD_LIBRARY_PATH="/Users/carlton/lib/sqlite/3.35.4" python3 ~/bin/sqlite_config.py
Contrast the same when run with a pyenv installed python:
~ $ pyenv which python3.8
~ $ DYLD_LIBRARY_PATH="/Users/carlton/lib/sqlite/3.35.4" /Users/carlton/.pyenv/versions/3.8.3/bin/python3.8 ~/bin/sqlite_config.py
The expected result, in both cases, is that the last lines should read:
I don't know if this is the result of a tightening in macOS' SIP in Big Sur (or something else entirely...) — I thought to test it by installing the official build in a different location (so not in the SIP protected `/Library/` space but somewhere in `~` but the installer doesn't look like it allows that (no doubt for good reasons).
Next step for me with be building from source to see if I can dig deeper, but I thought I'd report it, as it does look like a change in behaviour from the *success* reported in 40198.
Thanks very much!
