GPL v3 app with copied GPLv2 or later source and linked against LGPL-2 or later libraries (original) (raw)

(Please CC: me, I'm not subscribed to -legal)

I just wanted to check that I've got this right as upstream and as maintainer:

gpe-cash is a new application (unreleased), designed as a finance manager for handheld devices using libgpewidget (GPE Palmtop Environment) and GnuCash source code. gpe-cash includes code forked from GnuCash (because GnuCash upstream are unwilling to break up the upstream codebase to provide the same code) and is linked against libgpewidget, amongst other libraries. It also provides a new library that will be used later by another finance program for GPE to deal with small business needs like invoices. (I've reduced the package installed size to less than 1Mb whilst still using GnuCash financial objects.)

I've checked http://gplv3.fsf.org/dd3-faq and I considered putting this notice, along with the GPLv3, into debian/copyright (unless GPLv3 appears in /usr/share/common-licences before gpe-cash is ready for release) and including GPLv3 in the upstream tarball:

Copyright Holders: Neil Williams linux@codehelp.co.uk GnuCash code in src/objects : (In alphabetical order, using the declarations within the gnucash code.)

The GnuCash source contains a larger list of other contributors who have submitted patches etc. but it is not always possible to identify which of those people have had a hand in the gnucash code that is used by gpe-cash. If you know someone who has been left out, email Neil Williams linux@codehelp.co.uk

All the gnucash source code used in gpe-cash is "GPLv2 or later". The Gtk frontend for gpe-cash is GPLv3 or later. I am therefore using my option to distribute and modify the gnucash source code under a later version of the GPL, bringing the entire source code for gpe-cash under version 3 of the GPL. This specifically includes the shared library libqofcashobjects. Neil Williams codehelp@debian.org

libgpewidget, GPE and gpe-cash:

libgpewidget is licensed under the Lesser GPL v2 or later, like most gpe libraries. gpe-cash under the GPLv3 can be linked against these libraries. See http://gplv3.fsf.org/dd3-faq

Have I got that right?

I am also thinking of attributing copyright on the Gtk frontend to the FSF but that shouldn't make any difference to the licence(s).
