We are using SDL, SDL_image, SDL_mixer and SDL_ttf. All of these are
supported in part by Sam (along with some other people). However, each one
has a license (README) file that we are suppose to distribute with our game
to comply with the LGPL. Each of these files is identical.
The fact that these libraries are licensed under the LGPL forces you to
release your program under the LGPL.
- -> section 2. c “You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.”
But you may choose to alter the licensing notices to apply the terms of the
Your application being under the LGPL and respecting it, adding a COPYING file
is mandatory following the first section. As you cannot alter the notices
that refers to the license, you cannot simply remove the COPYING files.
- -> section 1. "You may copy and distribute verbatim copies of the Library’s
complete source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate copyright
notice and disclaimer of warranty; keep intact all the notices that refer to
this License and to the absence of any warranty; and distribute a copy of
this License along with the Library. "
If you “restructure” the source code of the libraries and put everything in
the same directory, then having one file will suffice as each references to
the LGPL in the source files talks about “COPYING file” and there is one.
Else, if the source code of those libraries are splitted each one in its own
subdirectory or something alike, then the COPYING/README file must present in
The need for this is the essence of the LGPL : you can make tons of things
with the library, given that
- the copyright holder is easy to find out
- the license is readable without having to use another source of information
than the source distribution
- the changes made to the original version of the library are stated in clear
- the licensing terms of the LGPL are preserved or replaced by the GPL
Sam, do we need to have 4 copies of this license file or will one suffice?
So, as stated above, this depends on the structure of your source
distribution, although you are very likely to have 4 copies…
