Just a quick note There has been some major changes going on in the OPAL SVN. Some of which have had an adverse impact on both h323plus and GnuGk. As of this morning, with the help of Jan, both the h323plus and GnuGk CVS compile with the OPAL SVN on both windows and linux. You may see some depreciation warnings, you can safely ignore these. We are in the process of rectifying the problem. Simon
