Hi Binan,
I found that page in the very beginning of my search and, indeed, it
provides really useful information on this case.
About the statement, I understand that "affected code" is the code that
uses (directly or indirectly), compiles or links against the library -
which will be the opensips module. Correct ?

Hi Bogdan,
So OpenSIPS module is not derivative.
I have found this page :

and at the end : "all the copyright holders for the affected code agree"

Hi Binan,
Just to clarify on the "module" thing - an OpenSIPS module is a shared
library that is dynamically loaded by OpenSIPS core at runtime. So,
there is no linking between core and modules, but they share and use code.
Secondly, the non-GPL lib will link only to an OpenSIPS module,
without being linked or used at all by the core part.
Maybe this will help a bit .

Hi Bogdan,
I think Opensips modules are considered derivative to the core (
OpenSIPS module needs "help" from the core. It is not stand alone ).
Special exception clauses can only be applied to an original work
and never a derivative. If the core is linked to the lib then all the
copyright holders of the core states the exception.
You can go around this by considering this module as part of original
work not derivative. In this case we backed to above (All must state
the exception).
This must be confirmed by IP lawyer.

Hi Binan,
And this exception clause (btw, found something similar here
http://lists.debian.org/debian-legal/2004/05/msg00595.html), needs to
be stated by the copyright holders of this new opensips module (that
will link to the lib) or by all copyright holders from core + module
? This is the tricky part :)

Hi Bogdan.
Yes .
Special exception clauses allows this combination (linking). This is
what i know.

Hi Binan,
Already when through that page, but not 100% clear.
As I understand it, to make it possible you should :
1) the copyright holders of the GPL code should agree on an
exception to link against the non-GPL lib
2) owner of the non-GPL lib you give you the permission to use
it (if not fully public).
?

*Ämne:* [OpenSIPS-Devel] [HELP] Advising on GPL license issue
Hi all,
As I'm not an expert in this, I'm looking for someone to advise on
a more complex issue regarding GPLv2 license.
Shortly - developing an opensips module that needs to link to a
non-GPL (and not compatible) library (available for public in
binary format, with proprietary license).
For details or whatever feel free to contact me offline, not a problem.
Help will be highly appreciate not only be me, but by the project
and community (as a really nice feature depends on finding a
solution here).
Regards,
