Topic: License compatibility question.

There is a "Giftware license" in both opensurge packages about the Allegro, though in the allegro-5.2.8.0
there are other licenses and not the "Giftware license" so I do not know how opensurge had any way to place any allegro under a "Giftware license".

The Giftware-license.txt
shows

==============================================
============ The giftware license ============
==============================================

   Allegro is gift-ware. It was created by a number of people working in
   cooperation, and is given to you freely as a gift. You may use, modify,
   redistribute, and generally hack it about in any way you like, and you do
   not have to give us anything in return.

   However, if you like this product you are encouraged to thank us by making
   a return gift to the Allegro community. This could be by writing an add-on
   package, providing a useful bug report, making an improvement to the
   library, or perhaps just releasing the sources of your program so that
   other people can learn from them. If you redistribute parts of this code or
   make a game using it, it would be nice if you mentioned Allegro somewhere
   in the credits, but you are not required to do this. We trust you not to
   abuse our generosity.

The opensurge-0.5.2.1
and in the opensurge-0.6.0.3
show the

GNU GENERAL PUBLIC LICENSE
                       Version 3, 29 June 2007

but there is also the LICENSE-GothicA1.ttf.txt
in opensurge-0.5.2.1
or in the file it shows

SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007


https://www.gnu.org/licenses/license-list.html#SILOFL
shows this license is incompatible with the GPL3 so I do not know how a program that is under
GPL3
can also have fonts under
SIL OPEN FONT LICENSE
as I think any thing under the GPL3 makes all parts under the GPL3.

I do not think in opensurge-0.5.2.1
there is a font exception in it.
https://www.gnu.org/licenses/gpl-faq.html#FontException

Also the SIL OPEN FONT LICENSE Version 1.1
does show the font code as "Font Software"
so I do not know how well it can be placed into the GLP3 licensed program.
.

The opensurge-0.6.0.3
does not look like it uses the GothicA1 font so also does not need the SIL OPEN FONT LICENSE.
I think there may be less license problems in it, though still the
"allegro how did they (opensurge) re-license it (allegro) that way"
question.

https://wiki.hyperbola.info/doku.php?id … guidelines

shows in part

All chosen primary and compatible license files from the upstream source should be placed in /usr/share/licenses/$pkgname.

Though opensurge-0.5.2.1
may not have compatible license files in it.

I do not need these games, or most games, I just saw the licenses when looking at things in the "extra" PKGBUILD things of Hyperbola.

Re: License compatibility question.

OpenSurge is licensed under various licenses and is going to be fixed with a better notation for next updates. So parts of the software is licensed under the GPL-3, other parts licensed different. That is a common point for many free, libre games.

No need to remove anything here, just to modify and that is already done but needs buildtime.
You can look for licensing for allegro at Debian: https://metadata.ftp-master.debian.org/ … _copyright

When you use allegro you have not to include the licensing from it as you only build upon and it is standing on its own. But you are nevertheless right: The original noted licenses for OpenSurge are not sufficient and are redone.

Human being in favor with clear principles and so also for freedom in soft- and hardware!

Certainly anyone who has the power to make you believe absurdities has the power to make you commit injustices: For a life of every being full with peace and kindness, including diversity and freedom. Capitalism is destroying our minds, the planet itself and the universe in the end!
