> 1. How much RAM is used at run-time by the FLTK library ? That entirely depends on what widgets you use, and how many of them - the recommended method to use fltk in an embedded app (well, any app, really) is to link statically and then strip the binary, so you only end up with the parts that are actually used, and no other overhead.
But, unless you know which widgets, and how many, you are going to use, it is impossibly to say how much that will be. The per-widget overhead in fltk is really small though, only a few tens of bytes. > 2. How much space on Flash is needed by the FLTK library ? See answer to (1) above. Do not use dynamic linking or shared objects, link the app statically and strip it. That gets you the smallest footprint as you are only loading the bits you actually need. > 3. Does FLTK work on framebuffer ? There is a port of the 1.1.x series for framebuffer use, but the core fltk does not. > 4. Does FLTK support DirectFB ? If so, which version of FLTK > supports which version of DirectFB ? (I heard that the > DirectFB support is not available on the most recent version > of FLTK...) It is not "officially" available with any version of fltk, but as I say, there are ports around that do work. You do lose some functionality however - for example I don't think the FB version has GL support, that sort of thing. Can you not just run tiny-X/kdrive? That ought to fit on your target and is compatible enough that X apps Just Work without messing about with frame buffer support and so forth. Works fine on my OMAP demo board at any rate, which doesn't have *that* much more memory... > 5. Does FLTK work with uclibc, or is glibc required ? I've never built fltk against uclibc, so can't say for certain. I have built it against newlib and that was fine, so probably uclibc would be OK too. -- Ian SELEX Sensors and Airborne Systems Limited Registered Office: Sigma House, Christopher Martin Road, Basildon, Essex SS14 3EL A company registered in England & Wales.
