This is a GTK+ Webkit app that is intended to work similarly enough to
the iOS app being developed in the "Mobile" folder that (some kinds
of) problems in that also show up in this app, and can be investigated
by people with no Mac or iOS device.
How to build this:
Use a separate tree of "online". Do NOT use one where you build a
normal Online.
Run autogen.sh, then configure:
./configure --enable-gtkapp --with-lo-path=/home/tml/lo/master/instdir --with-lokit-path=/home/tml/lo/master/include
Obviously, adjust the path to your LibreOffice build tree as necessary.
Then make.
You will get the gtk/mobile executable. Run it. Debug it. Fix it.
