Re: [Freeswitch-users] Posibility to build a module for chan dongle

3 Jan 2012

      I'm not going to start a holy war on the list, nor spread fud, but:

http://www.mozilla.org/MPL/MPL-1.1.html
http://mpl.mozilla.org/wp-content/uploads/2011/08/MPL-RC1-typography.html

In section 3.3 of MPL 1.1 and section 3.7 of MPL 2, "Larger Works" are defined as "means a work which combines Covered Code or portions thereof with code not governed by the terms of this License", and other licenses are specifially allowed under these provisions under the MPL.

The problem is with including MPL code in works licensed under GNU licence, as covered http://www.gnu.org/licenses/license-list.html, and as long as you are including MPL2 code and have any of the GNU2 series license, you are OK that way, also.

From Wikipedia:
The MPL is GPL-incompatible because the GPL module cannot be legally linked with an MPL module. However, versions of the MPL such as MPL 1.1 have a provision that allows part of a program to offer the GNU GPL as an alternative choice, thereby allowing part of the program to have a GPL-compatible license.

That doesn't mean that the project can't accept code, it means that that the project managers don't want to, for whatever reason, and that is completely up to them.  But sending someone off with the misconception that it is not allowed by license is just going to lead to future problems for someone.

Thanks,
Rob

Rob,
no, you're wrong.
You cannot include GPLd code in FreeSWITCH.
That has been clarified multiple times in the mailing list too.
Please do not spread wrong info, that can lead to people wasting their time.

While MPL is not compatible with GPLd code, I don't think that GPLd code is
compatible with MPL, as MPL is slightly more restrictive. In fact, there are
GPL2 projects included now in the form of automaticly built external
libraries...

Hi,

Whilst you can use the code from chan_dongle privately, for your down

purposes, with Freeswitch, it cannot be distributed with Freeswitch. The

licence for chan_dongle is GPL v2. This is incompatible with Freeswitch.

The web page for the chan is this:

http://wiki.e1550.mobi/doku.php?id=installation

It is open source. so we can use the sources without any issue.

Sorry me if the information is not really exaustive or if i maid many

By the way, sorry me for my english. It is not really good.
