Re: [tools-pmc] [CQ 8772] Cygwin- as "works with" exception to full IP r

[Doug Schaefer <dschaefer@xxxxxxx>]

I am not a lawyer, but I've never been comfortable building anything on Cygwin. If Titan ends up being consumed by a commercial product it would GPL that product, in my not a lawyer opinion.

But then if the user is building this, why is this even a CQ? Sorry if this is dealt with in a later e-mail, just catching up on the traffic.

Hi David,

 

The practical implications of this CQ are in our interpretation  that it allows Titan to be built on Cygwin if  the user so wishes. Cygwin, or parts of it  will not be distributed in any form by Titan.

 

 

Quote from https://cygwin.com/licensing.html:

 

 

 

Cygwin™ Open Source Licensing Exception

As a special exception to GPLv3+, Red Hat grants you permission to link software whose sources are distributed under a license that satisfies the Open Source Definition with libcygwin.a, without libcygwin.a itself causing the resulting program to be covered by GPLv3+.

This means that you can port an Open Source application to Cygwin™, and distribute that executable as if it didn't include a copy of libcygwin.a linked into it. Note that this does not apply to the Cygwin™ DLL itself. If you distribute a (possibly modified) version of the Cygwin™ DLL, you must adhere to the terms of the GPLv3+, including the requirement to provide sources for the Cygwin™ DLL, unless you have obtained a special Cygwin™ license to distribute the Cygwin™ DLL in only its binary form (see below).

See http://opensource.org/docs/osd/ for the precise Open Source Definition referenced above.

 

 

Our understanding   is that this exception   prevents tainting of the open source code.

 

However, I agree  this might require deeper legal scrutiny.

This I'd like to give a tentative -1 one to this one -- but depends on some legal interpretations I'm not qualified to make, definitively.

It may be ok, but from reading the license quoted in CQ it sounds like there *might* be some "tainting" of the open source code.
If that's not the case, then fine, it's be ok with me as a "works with".

If that is the case, that there is some "copyleft" implications,  then I think that means that commercial products (part of which might be closed source) could not use or build on Titan.
And since that would be a pretty big "change of direction" for Eclipse Foundation, I'd want EMO Director or Board to be involved with deciding that.
