jhbuild setup

Start with a working "normal" sugar-jhbuild installation.

Compile/install a fixed pygobject with this chain-up fix. F16 build available from http://koji.fedoraproject.org/koji/taskinfo?taskID=3473257

Apply this patch to sugar-jhbuild: http://dev.laptop.org/~dsd/20111029/sugar-jhbuild-sugar-toolkit-gtk3.patch and build the new GTK3 based sugar toolkit:

./sugar-jhbuild build sugar-toolkit-gtk3

The sugar-toolkit gtk2 version needs some modifications for some restructuring that gtk3 work has prompted. Check out our branch where this happens;

cd source/sugar-toolkit
git remote add -f gtk2-mods-for-gtk3 git://git.sugarlabs.org/~erikos/sugar-toolkit/sugar-toolkit-gtk3.git
git checkout -b gtk2-mods-for-gtk3 gtk2-mods-for-gtk3/sucrose-0.94
make install
cd ../..

And similarly for sugar:

cd source/sugar
git remote add -f erikos-gtk3 git://git.sugarlabs.org/~erikos/sugar/sugar-gtk3.git
git checkout -b gtk3 erikos-gtk3/master
make install
cd ../..

And for sugar-artwork:

cd source/sugar-artwork
git remote add -f erikos-gtk3  git://git.sugarlabs.org/~erikos/sugar-artwork/gtk3.git
git checkout -b gtk3 erikos-gtk3/master
make install
cd ../..

Pending upstream work

All of these have been worked around (or will be worked around) for now, at the sugar level.

• missing parts in pango introspection, 646788 does contain what we need (there are quite a few introspection related pango bugs open atm, from a quick look I found https://bugzilla.gnome.org/show_bug.cgi?id=660070, https://bugzilla.gnome.org/show_bug.cgi?id=627973, https://bugzilla.gnome.org/show_bug.cgi?id=645792, https://bugzilla.gnome.org/show_bug.cgi?id=645871, https://bugzilla.gnome.org/show_bug.cgi?id=646788 even with patches attached already for a while)
