SDL and GTK2

[Jim Norton <jimnorton jimnorton org>]

I'm attempting to learn SDL and would like to use GTK2 as the GUI 
framework under Centos 5.8. I've looked at some sample code, but so far 
I've not able to get any to compile.

For example, I tried this sdl-gtk-demo but it appears to require an 
older version of GTK?

What is required for an SDL application to draw onto a GTK2 widget or 
window? My set up is the following:

1-Centos 5.8
2-GTK2
3-The standard GCC that comes with Centos 5.8

Because this is targeted for an embedded system, I don't have the 
liberty to use a newer Centos distribution.

Perhaps a solution may be to write a standalone SDL application that 
uses OpenGL to do my image animation and write to the X11 window ID of a 
GTK2 widget. Does this seem like a reasonable approach? And if so, can 
anybody point me to some code samples?

Thank you,
Jim
