Unable to connect with TLS - something about an incompatible ssl version

[travis-leith]

If I try to open a connection I get OpenSSL initialisation error.

If I run sslinfo() I get

Error in sslinfo() : 
  kdb+ : Could not initialize openssl. Error was incompatible ssl version
.

I am using the latest version of openssl, according to the website linked from the KX ssl instructions. OpenSSL 1.1.1l 24 Aug 2021

This same website tells me to punch myself in the face if I want to use an older version of openssl ;)

Hi travis, this is due to an older version of the client library being included in this repository (which does not support openssl 1.1.1). There is a PR open to address this #66 . In the mean time if you have a local clone of the rkdb repo you can workaround by updating the version of the client library (w64/e_static.lib) using the latest version at

https://github.com/KxSystems/kdb/raw/master/w64/e_static.lib

And rebuild/reinstall the rkdb package in R with

devtools::install_local('PATHTOLOCALCLONE',quiet=TRUE,force=TRUE,INSTALL_opts=c("--no-multiarch"))

@jhanna-kx is there any particular reason why the PR has not been merged? Can I consider this fit for production use?

Looks like this repo has not been updated for years?

@jhanna-kx this used to work for me, but now when I try to do it I get the following:
