If you just want to make minimal changes to make it work with Gtk+ 2.x somehow, 2.4 is enough. If you want to modernize the code I would recommend at least 2.6 which added lots of useful modern concepts and features. The current version is 2.10 -- however it was released less than a week ago so I would not make it a requirement now (and when it will start to be an acceptable requirement, well, opinions on that differ by several years). Gtk+ 2.8 added Cairo but otherwise the API saw only minor additions that may not overweight compatibility with 2.6. > What I did was copy the code to a new directory, and replace the > `gtk-config ...` with `pkg-config ... gtk-2.0` in the Makefile.

There are no files with .hx extension in gtk+2-2.4.3-i486-1.tgz. So they must belong to something else. The set of headers has changed from the old gdk-pixbuf, so if some don't exist then they just don't exist. The stuff can be elsewhere or it works differently now. > 1.

Very simple or specifically written apps can -- for example most Gtk+ 1.2 tutorial sample programs do, although they use more deprecated functions than non-deprecated. But complex apps won't. See also http://developer.gnome.org/doc/API/2.0/gtk/gtk-changes-2-0.html and the other migration guides nearby. > 2. Gtk+-2.4.0 is, or is not, usable for development. y/n. See above.

Maybe here, try to ask a question instead of asking whether a question would be answered if it was asked. IMO coding an app to work with both 1.2 and 2.x is a waste of time, if you want to go the least common denominator way, use something like wxWidgets.
