Hi,
Which license is GtkAda released under? (Am I allowed to develop proprietary software which uses GtkAda without having to release it as open source?) Kind Regards Robert _______________ Robert ter Vehn robert.tervehn@... _______________________________________________ gtkada mailing list gtkada@... http://lists.adacore.com/mailman/listinfo/gtkada |

The version of GtkAda available via the libre site is released under the GPL, so is only suitable for free software development. GtkAda Pro which can be purchased from AdaCore (sales@...) is released under the GMGPL which is suitable for proprietary developments.

If I don't distribute GtkAda, do I need a GtkAda Pro license? For example, <http://home.roadrunner.com/~jbmatthews/gtk/lady.html> John -- John B.

That being said, assuming "lady.html" is distributed under the GPL, then the use of GtkAda from the libre site seems appropriate to me.

Arno, Thank you for responding. I intend to seek counsel, but she will want to examine the relevant licensing terms. Were I to distribute a binary version of the example cited, it would include two instances of the generic package Gtk.Handlers and one instance of Gtk.Main.Timeout. In addition, it would link to code derived from your exemplary Double_Buffer package. It would include no other GtkAda code. All three files are marked as permitting redistribution under the terms of the GNU General Public License, version 2, and each file includes an exception for instantiating generics and linking. Are there any other licensing terms that would apply? Thanks, John -- John B.

OK well we're into "what if" now :-) As I said, without giving legal advice which I'm not qualified to do, things are pretty simple: All the GtkAda code from libre that you are using is licensed under pure GPL, with no "exception", so either your code is distributed with a license compatible with the GPL, and you are fine, or it is not (e.g. using a proprietary license) and in this case, you could be in trouble.

Of course, I wish to avoid trouble :-) I frequently produce and consume GPL, GMGPL and LGPL licensed software, and I am happy to comply with the terms of redistribution. Many of the GtkAda source files contain the text of the GMGPL exception; some do not. Are you saying I should not rely on the presence or absence of the exception in the individual source texts obtained from this repository: <http://svn.eu.adacore.com/anonsvn/Dev/trunk/GtkAda>?

The main and simple message is that all the software available via the libre site, including svn.eu.adacore.com/anonsvn is provided under the pure GPL license.
