Preface
Even though JACK is mainly based on
GPL &
LGPL
software components, the iOS
version of JACK has been released under revised terms. The exact terms are
shown below. The revised license terms were necessary due to the following
reasons and purposes:
-
To allow commercial third parties to use the JACK iOS Software
Development Kit (SDK), allowing third parties to link against the static
JACK library contained in the SDK without requiring them to publish the
source code of their own app.
Background: This license exception was necessary because Apple does not
allow DLLs to be used by apps on the App Store, forcing iOS app
developers to statically link against the JACK iOS SDK (JACK client
library), where the latter was originally released under LGPL terms and
the LGPL does not allow proprietary (non free) software applications to
statically link a LGPL library.
NOTE: This license exception does ONLY apply to the JACK iOS SDK.
It does NOT apply to the JACK server / JACK graphical user interface
software components!
-
To allow Apple distributing the main JACK app (JACK server) on the Apple
App Store.
Background: This license exception was necessary because the JACK server
(also known as jackd) was originally released under GPL terms. The GPL
requires distributors of software in binary form to provide the source
code of the software as well. Apple however does only distribute apps
in binary form on the App Store, not in source code form. Which in turn
makes it impossible to distribute GPL apps over the Apple App Store.
NOTE: This license exception does ONLY apply to the JACK iOS server.
It does NOT apply to the JACK iOS graphical user interface (GUI).
You find the exact license terms for the iOS version of JACK below. If you
