Port to Gtk - but to what one?
==============================

About 2005 I wrote a small  program for statics of simple structures by
means of  the direct stiffness method  [1]. In short: it  is written in
the ANSI C language so it is pretty well portable. But it uses the Gtk+
library (version  2.x) for  GUI and for  graphics. It  was contemporary
when I wrote the program and I have not touched it since.

It was probably a good decision in that time because the program (which
GUI)  was  portable  across  several  platforms (it  worked  on  a  Ben
NanoNote, on  a Neo FreeRunner,  on Windows  machines, on the  IRIX 6.5
with the  Freeware or  the NekoWare Gtk  ports, on a  Solaris 9  and of
course on all sorts of Linux distros and platforms).

But now I  have a problem. Now I  have a SGI Indigo with  IRIX 5.x. The
best Gtk+ that  I can get there  is 1.2. But it  means taht GUI-related
code has to be re-written.

Well, the  second problem.  Now I  have the Raptor  CS BlackBird  (so a
modern POWER/PowerPC  with the modern  Linux). The Gtk+ 2.x  works here
just now but it is going to be  removed and replaced by the Gtk 3.x. It
means that I will have to re-write my GUI code if I will wish to use my
program in future.

I don't have enough  time nor patience to make two  ports. So which one
I should make?

P.S. The more native  Motif [2] port is out of game as  it would mean a
considerable re-write of  the code. I tried to do  it and abandoned the
idea.
