Funny thing, after looking inside Bookeen firmware people on our IRC channel found that not only "platform" from the unknown OEM violates GPL, but also book reader which is copyrighted by Bookeen itself.

In what way does the Boo Reader violate GPL? It goes back to the old CyBook. Definitely written by Bookeen (with info and/or code from MobiPocket).

Given that Bookeen has clearly stated its own development of Boo Reader and has stated the info on Mobipocket, I presume that Bookeen would make a more complete statement of copyright AND GPL if there were a 'scrolling' display capability. I think maybe Bookeen just wanted to put the most important information out there. Of course, they could, at some point, create a series of dialog boxes which display the various copyright and GPL statements.

Perhaps dottedmag thinks that any software that runs on Linux must be GPL as well? Er, GPL doesn't work that way...

If Bookeen's Book Reader is simply an application running under Linux, there is no requirement I know of that it be open source or licensed under the GPL.

Perhaps guys on channel ACTUALLY LOOKED INSIDE instead of just guessing and found it STATICALLY links to GPL-ed libraries.

Are the libraries it links to GPL or LGPL?

Well, the thing you quoted said GPL...

But it does not matter with respect to breaking GPL or LGPL since for LGPL it holds that:
Quote:
Essentially, it must be possible for the software to be linked with a newer version of the LGPL-covered program. The most commonly used method for doing so is to use "a suitable shared library mechanism for linking". Alternatively, a statically linked library is allowed if either source code or linkable object files are provided.
So the source code or linkable object files are needed here if it is statically linked with LGPL:ed libraries.

So they really should have an interest in clearing up as much about the GPL issue as they can on their end.
I belong to that category of people and the fact that they supported open formats and could be expected to respect GPL and similar things was a big factor in my decision to buy a Cybook. So I feel kind of disappointed and cheated by all his.

The Boo Reader binary definitely includes the pieces of the following:
1) glibc
2) libgcj
3) jpeglib
4) pnglib
5) zlib
6) boehm gc
7) freetype
8) mupdf
9) expat
10) IBM's ICU
11) fonts by URW
12) iconv
And probably more not readily-identified libs. Not all of above is (L)GPL but enough, I think, to make them obliged to make source code available.
Funny thing is that Mobipocket code is compiled in too (with gcj). I wonder if that means it'll have to be open-sourced too.

Compiling code with any Gnu compiler does not mean the code has to be released in the public domain. This forum is getting carried away I am afraid. Study the GNU copyleft statements a little closer.

Why do you think anybody believe that? Combining your code with GPL:ed code so that it becomes a derived works make your code GPL. And if it is LGPL than the user has to be able to recreate the binary when new libraries are available. If you statically link to a GPL:ed library then it is a derived work.

Maybe all the licenses for the libraries are other licenses then GLP or LGPL but that is another claim.

CAN YOU DAMN STOP GUESSING? Have a look at the binary. All the things mentioned ARE COMPILED INTO THE SINGLE BINARY.

Please correct me if I'm wrong, but "glibc" is the C runtime library, is it not?. Surely every C application has to include that, doesn't it? You aren't saying that every application that uses the C RTL has to give away its source code, are you? That would make writing commercial Linux applications impossible!

A little bit simplified: Dynamic linking to the glibc (and any LGPL licenced library) is allowed for any program under any licence. But if you statically link your program to a LGPLed library you have to release all your sources under the terms of the LGPL.

So does Bookeen HAVE to give the Mobipocket code out along with the OS code under the terms of GPL? Can anyone give a definitive answer?
