Emacs Has Been Violating the GPL Since 2009
Digana writes "Emacs, one of GNU's flagship products and the most famous software creation of Richard Stallman, has been discovered to be violating the GPL since 2009-09-28 by distributing binaries that were missing source. The CEDET package, a set of contributed files for giving certain IDE functionality related to static code analysis, has distributed files generated from bison grammars without distributing the grammar itself. This happened for Emacs versions 23.2 and 23.3, released during late 2009, and has just been discovered."
Bison's output isn't binary, it's C (a somewhat contrived and difficult to understand C, but C nevertheless). It doesn't generate "compiled binaries", as the article points out.
It's still source code. Maybe not the original source code, but source code anyway. I don't think that violates the GPL intrinsically (maybe it violates its spirit, but not the license by itself).
Mod parent up. There is no stipulation in the GPL that source code must accompany any distribution of binaries. Total myth.
Section 6 of the GPL
"You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
[...]
"# b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
"# c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
"# d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements."

If not, then it's not breaking GPL.

Quick Guide to GPL v3
The actual wording for network distribution in the GPLv3 says you just have to make or have the source available in the same methods that the binaries were
GPLv3
I bet we can find Emacs source on the same server we can find Emacs binaries.
