David, Nikos, Is there a known minimum version of GnuTLS needed to build OpenConnect 7.08? The web site does not specify any minimum versions of GnuTLS or OpenSSL (http://www.infradead.org/openconnect/building.html) ? but I've been getting several issue reports on GitHub from people trying to build openconnect-gp with old versions of GnuTLS (e.g. https://github.com/dlenski/openconnect/issues/33). The build requirements for the GP version are no different from the official version. It would be good to clarify the minimum library versions required if they're easy to pin down. Thanks, Dan
