 Have you considered talking to your local version of the EFF?

Thank you for your kind advice, and for the link you provided. I'll
consider writing to the EFF.

A copyright question to wine developpers

2012-06-11 Thread Christophe-Marie Duquesne
Hi,

To my understanding, wine is a reimplementation of the MS system. As
far as I understand, you take MS public headers and reimplement their
functions. If that is how it works, then how do you deal with
copyright? The MS headers certainly come with a copyright clause: how
is it possible to redistribute these headers with wine?

The reason why I ask this: I just rewrote an opensource implementation
of a closed-source library. This opensource implementation is meant to
be fully compatible with the closed source one: I reimplemented all
the functions provided by their header, and anyone using the closed
source one should be able to use my library as a replacement. My
problem, though, is with the distribution of the header: Since I want
to be fully compatible with the closed-source implementation, I have
to, somehow, use the same header. I could probably modify it so that
is *looks* different, but for the compiler, the API *needs* to be the
same.

Since you seem to have the same problem with wine (and you probably
dealt with it succesfully), I wanted to ask you how you are solving
this problem. Do you rewrite the headers? Do you copy them raw?

Thank you,
Christophe-Marie Duquesne

I wouldn't have a clue about France or my own country however it now
appears rather clear cut to developers in the United States.  You'd
assume this is the common sense ruling that should follow any action
of this type in other countries though.

The Windows headers are copyrighted and Wine cannot redistribute those.

yeah, what happens is the header is reimplemented, not simply
copy-pasted from Windows.
Even if the API is not copyrighted, the header contents still are.

Well if you rewrite a header such that it is 100% compatible with an
API (which means: 0 change in client code), it has to be very similar
to the one the API came from.
- The macros have to be the same, in order to expand the same way in client code
- The function names have to be the same as well
- Same goes for the typedefs
- The header name also has to remain the same.

What can be different:
- function argument names
- indentation
- comments

In the end, it seemed pretty silly to me to do that. But, if that is
the solution to my copyright problem, I am doing it!

 Have a look at what Google does for the Linux headers in Android. They
 essentially process them with a script and remove comments, inline

 Look at the argumentation.

This really helpful. Thank you very much.
