RE: X lib support for embedded systems.
I don't need the complete X11 thing. I just need these libraries: X11, Xext, Xft, Xcursor, Xinerma and Xi To get fltk working. Well, I am a novice candidate for the X11 world. I need help to achieve my application to run using a touchscreen keypad. My arm processor is of 266MHz.

RE: X lib support for embedded systems.
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?

In fact I have built a system on top of a touch screen with Xorg, including a full XUL based browser. My storage space limitation was 64MB, so I stopped optimizing for that after I got to a 43MB squashfs system. After removing XULrunner and GTK+ and the obviously related thing from that image and squashfs'ing again, its size becomes 24MB for me, without any hard trimming at all. With building from scratch, without the less obvious GTK+ and XULrunner dependencies pulled in, and some slightly more trimming, I'm confident less than 15MB is quite achievable. So I do not see why X windows would be inappropriate for embedded platforms, at least when looking at storage space limitations. For that the touch screen handling would be very easy from Xorg, and depending on the graphics chip, might even get considerable graphics acceleration that is not possible with DirectFB. That said, I can not offer any free help in building it small. Just making sure X11 isn't thrown out from the list of possibilities without a good reason. try using directfb But sure, DirectFB is an option as well, especially if you are developing for a platform that provides graphics acceleration on top of DirectFB, but not on top of X11. port of fltk (if it's still working...) or take peek at Xfast and clones... ___ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com

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? X windows is not appropriate for embedded platforms , I disagree with that sentiment. X.org works fine on embedded platforms, and is used on such systems with success.
