Gtk 2.2 and Webkit to use Aqbanking 5 on Windows - How can I contribute?
As Phil and Christian discussed already in: https://lists.gnucash.org/pipermail/gnucash-devel/2010-December/030585.html
and as Christian told me today in: https://lists.gnucash.org/pipermail/gnucash-de/2011-February/007824.html
Gtk 2.20 is needed to use Aqbanking 5 which has great new improvements.
What we need is webkit/gtk compiled for win32 using the mingw environment. webkit can be compiled for win32 (obvious since that is the engine used by Google Chrome).
I've downloaded the latest stable webkitgtk-1.2.7 from http://webkitgtk.org/?page=download and gave it a try on my Windows/mingw system, where I also usually build a gnucash windows binary.
Turns out webkit requires some more tools than what is available as pre-compiled windows binaries. Bison and gprof are required and still available, but "flex" is required in version 2.5.33 whereas the latest windows binary of it on gnuwin32 is 2.5.4. As Phil already wrote, because of this it is most probably easier to cross-compile on a Linux box with the mingw32 cross compile toolchain.
