[New-bugs-announce] [issue38873] find_library for libcrypto and libssl on Catalina returns the unversioned library

[Sarah Harvey]

New submission from Sarah Harvey <s at shh.sh>:

I've been tracking this through a bunch of different projects now. With the release of Mac OS X Catalina, libcrypto.dylib is a dummy library that causes an automatic segfault, to prevent upstream software from relying on it.

However a large amount of software makes use of ctypes find_library() which will return the path to the unversioned library.

It would be nice if we could specify "find the latest version" or similar so that we don't have to manually munge in a version, especially for strongly cross-platform libraries such as oscrypto.

I've filed a similar bug here https://github.com/wbond/oscrypto/issues/35 where it's very clear how it manifests itself.
