Ok its like this:
Our application was developed using fltk-1.3.x. We have lots of existing code 
that depends on fltk.

But the person who decided to use fltk-1.3 was really a moron.
Because, fltk-1.3 was modified by nano-X people to use nxlib interfaces, and 
all to test the nano-X (x server type) library.

This was a few years back.
Now we need a change in fltk. fltk-1.3 has latin1 encoding support and we need 
our application to internationalize.
Now for the same we have an answer with fltk-2.0. It supports utf-8. Also note 
that all of the fltk is built and tested with X11.

The problem is if I use the same setup, replace fltk-1.3 with fltk-2.0, I need 
to do lots of changes in nxlib and nano-X, for which I do not have enough time 
and also it is risky.
So I think that the easiest solution would be have X11 running on the system 
directly. So that fltk-2.0 runs without any problem.

Do you follow?

Yes, it's pretty clear now.But forget to mention about the OS part.Do you have 
to stick with any specific OS?if no, then I will recommend to use Angstrom with 
X(kdrive), which you can build lively by using online builder.

Angstrom repository already contains fltk (not sure about the version).

Hello there.

I am developing graphics system to one of our touch screen keypad.
I planned to use fltk-2.0 to achieve the same.
For this I required X11. But as the X11 is very huge, I wanted a slimmed down 
version of the same.
Basically X11 and fltk must occupy not more than 20MB!

Fltk basically uses these libraries from X11: -lXext, -lXft, -lXcursor, 
-lXinerma and -lXi.

Can anyone help me in building X11 for my system?
Not sure what exactly you want to do, there are already lot of options are 
available for embedded systems, Like Angstom, ubuntu-arm,android etc..
In all those OS having the capability of handling the applications with and 
with out X(frame buffer).

Instead of fltk, you can give a try with Clutter (Gtk Clutter).




Thanks,
Praveen
