We will want to move Emacs to GPL version 3 soon after that comes out.
First we need to check the licenses of the various libraries (other
than libc) that Emacs links with, and make sure that they are
compatible with GPL version 3.  

If some libraries are incompatible, that won't prevent the upgrade,
but we need to know about them in order to do the upgrade properly.

Would someone please volunteer to check this?

I did a quick search for files that don't include "either version 2,
or (at your option) any later version." The only ones have found were
either 1) in the public domain, 2) automatically generated, or 3)
without the standard license header (but, these are all copyrighted by
the Free Software Foundation).

That is the commands I used for my quick search:

  $ find -name *.c -or -name *.el -print > all
  $ find -name *.c -or -name *.el -print0 | xargs -0 grep -l "version
2, or" > license.ok
  $ for f in `diff -u all license.ok | body -s2 | grep "^-" | sed 's/^-//'`
do less $f; done

I hope that helps,

Thank you for checking this, but what we really need to check is not
the code of Emacs itself.  We need to check the licensing of the
libraries that Emacs can be linked with.

Yes, indeed. I misread your initial email. Anyway, here a summary of
the licenses of the libraries linked to the GTK+ version of Emacs. All
GPL-like licenses had the "or later version" clause. Most modified MIT
X11 licenses, just have a notice similar to the following added:

   Except as contained in this notice, the name(s) of the above
   copyright holders shall not be used in advertising or otherwise
   to promote the sale, use or other dealings in this Software
   without prior written authorization.

I attached the small script, I used, to check the licenses quickly of
the libraries on a Debian-based system.

[ A few minutes before sending this message, I saw that Alexandre
Vassalotti already did what's necessary -- nevertheless, my list might
be usefeful as a compatison.  Sorry for the noise. ]

Here is a probably inaccurate/incomplete list obtained on a gNewSense
GNU/Linux system with the snippet

$ P=/usr/bin ; for f in $P/emacs-snapshot $P/emacs-snapshot-gtk \ 
  $P/emacs-snapshot-nox ; do ldd $f ; done | sort | uniq -w 10 

(emacs-snapshot being Emacs from CVS trunk 25 Jun.  The only change
compared to EMACS_22_BASE is libgpm, if I'm not wrong.)

Where "GPL-compatible" is indicated in brackets, it is my personal
non-educated opinion; the license text is included in a footnote.
(Maybe I should have skipped the long annoying list of similar
non-copyleft licenses -- my apologies.)
Where the separator `/' is used, the library is dual-licensed.

    libgtk-x11-2.0.so.0           => GPLv2

Is it released under GPL version 2,
or under GPL version 2 or later?

    libgdk-x11-2.0.so.0           => GPLv2
    libgdk_pixbuf-2.0.so.0        => GPLv2

Same question.

For each library that uses the GPL or LGPL, the same question
needs to be answered.

Is that really only LGPL version 2?  That would be a problem.
(The rest of the libraries are not a problem.)

If that is the case, could you tell me what libcairo does?
Also, the names and email addresses of its main developers?

It is a core 2D graphics library, GTK+ depends on it.

Carl Worth <cworth@cworth.org> is the main maintainer.

Isn't the very fact that it is licensed under LGPLv2 sufficient to make
it compatible?

Correction: latest stable releases are under LGPLv2.1.  It shouldn't
be a problem.

Just a reminder that when we went through the copyright exercise
earlier in the year, it seemed to be the case that some of the images
included in Emacs from Gnome/GTK were under GPLv2 (no "or later").
Someone may wish to re-check these.

Seems to only affect (see READMEs) some files in: etc/images,
etc/images/gnus, etc/images/mail.

(I see many GNU projects have made new releases with the new license.
Will Emacs do this?)

rms:

  Is it really only version 2? If so, we may have to replace them in
  order to move Emacs to GPL version 3.

Since libcairo uses LGPL version 2.1, I just checked LGPL version 2.1
again.  It says that newer GPL versions can be used.  So there is in
fact no problen with libcairo.

Therefore there is no obstacle to relicensing Emacs immediatelky.  We
just need someone to volunteer to do the work.  We should do the trunk
and all the branches that are considered live, but we don't have to
do all the branches at once.

I think we should start with the release branch.
Since it's then sync'd to the trunk which is sync'd to the unicode branch,
that seems like the best starting place to avoid duplicated work.

    Just a reminder that when we went through the copyright exercise
    earlier in the year, it seemed to be the case that some of the images
    included in Emacs from Gnome/GTK were under GPLv2 (no "or later").
    Someone may wish to re-check these.

There is no legal conflict about the license of an image that Emacs
merely displays, so this is not a barrier to relicensing.  However, it
is not a good thing that GNOME images are licensed this way.

Can you tell me the specific file names of one or two of these images,
and where they come from in GNOME?

I don't need a complete list, just a couple of examples, fully
described.

Could we get the discussion moving again?]

I've been on holiday and it seems no-one else wished to reply.

It wasn't me who identified the license for the gnome icons initially.
Indeed, I can't find a clear statement about the copyright and license
for the gnome icons anywhere.

Emacs contains some icons taken from "gnome-icon-theme". Some specific
examples (as described in our etc/images/README file):

Emacs icon                gnome-icon-theme source
etc/images/attach         document/stock_attach
etc/images/delete         generic/stock_delete
etc/images/lock           data/stock_lock

The gnome-icon-theme source can be downloaded from

http://ftp.gnome.org/pub/GNOME/sources/gnome-icon-theme/

The tarballs contain a copy of GPLv2, but I cannot see an actual
copyright statement or a note about which version(s) of the license
apply anywhere in the source. Nor can I find this information in the
gnome VC repository. So basically, I have no idea what the copyright
for gnome icons is.

On a Debian system, /usr/share/doc/gnome-icon-theme/copyright says
that the license is "version 2" (no "or later"). This is the only
information I can find as to what the actual gnome icons license is.
