Googling around only confused me but in the end I found the answer in the sources (networkmanagent-0.9.0.8/vpnplugins/openconnect/CMakeLists.txt).

Earlier I got OpenVPN working after installing NetworkManager-openvpn using Robby Workman’s slackbuild so I was led to believe the same would apply to NetworkManager-openconnect. I need openconnect because my college uses Cisco An圜onnect VPN and it failed to install via the browser. I guess this would add OpenConnect as a dependency to the KDE build. After installing openconnect I manually built the networkmanagent package using the KDE.SlackBuild and sources from the slackware64-current repo (4.10.5). It seems the networkmanagent package depends on openconnect to be installed to build support for it. Unfortunately OpenConnect did not appear in the VPN list in the NetworkManager configuration. I successfully built the latest openconnect (5.01) and NetworkManager-openconnect (0.9.8.4) using the slackbuilds from (just had to bump version numbers). Would it be possible to add support for OpenConnect VPN to the networkmanagement package in KDE? At the same time, a binary which was compiled from that old source, on an older Slackware release, will usually still work without issues on the new Slackware. For successful compilation you would have to find patches or even use a newer version of the source. That is typically caused by updates to the gcc and glibc packages which introduce new library calls and interfaces which were not available at the time the older software was written. You will find that often, the source for an older version of software will no longer compile on a newer Linux distribution. let me know so that I can compile a new package! If you encounter any issues, like library linking errors. So, yes, you can use the “older” packages for lame and wine.

If I find a package for Slackware 13.37 which fails on Slackware 14 then I will specifically compile a new package for Slackware 14. Often that will just work (but not always). The golden rule for binary packages is, if they are not available for the Slackware release you are currently using, try a package for an older release.
