PyKX

OpenSSL 3.0.8 not compatible with PyKX?

Posted by eohara_kdb on July 3, 2023 at 12:00 am

Hi all,

We’ve installed PyKX with pip on an Amazon Linux EC2 instance, and when importing the package in a python session there are some "libcrypto* missing" errors. It seems like these might be associated with OpenSSL 1.1, whereas we have 3.0.8.

Is a certain version of OpenSSL required to load PyKX, or could this be some other issue?

Linux version:

[ec2-user@ip-172-31-23-74 ~]$ cat /etc/os-release

This message is warning about the underlying kurl.q library only.

PyKX has still imported and will still function (apart from any kurl features)
- https://code.kx.com/pykx/1.6/changelog.html#dependencies:~:text=The%20dependency%20on%20the%20system%20library%20libcurl%20has%20been%20made%20optional%20for%20Linux
If you wish to use kurl then the requirements are listed here:
