Hi Everyone

I am trying to compile the  freeswitch with mod_dingaling and Iksemel to work on Google voice or Gmail voice, I have read  

This  http://wiki.freeswitch.org/wiki/Iksemel_MSVS_project_example and the http://wiki.freeswitch.org/wiki/Dingaling

But I am stuck at  this  clause  

Add HAVE_GNUTLS=1 the the preprocessor compile in the iksemel project

What does this mean and how to go about this

Thanks in advance

Norman Lam
