Minimum GnuTLS version for OpenConnect 7.08?

[Daniel Lenski]

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
