Re: [Chicken-users] chicken scheme on handhelds.

[Matthew Welland]

I have an openembedded .bb file and I can make a chicken .ipk package just 
fine. What I haven't been able to do is get eggs to build in the same 
environment. However using the scratchbox cross compiling environment I was 
able to compile chicken and eggs and I built the ezxdisp 3d clock example 
and it ran fine on my ipaq. I have never been able to get a Familiar linux 
install of gcc to make exectuables so building on the Ipaq itself I haven't 
been able to do. 

My wish list for developing using scheme on the Ipaq (and potentially other 
handhelds):

1. cross compile and package chicken libs (most of chicken itself 
    isn't needed).   - DONE
2. cross compile and package sqlite egg - compiles on scratchbox
     but libs in scratchbox not in sync with openembedded
3. select a GUI. This is a problem. The status of available options is:
     i. bb  - pretty good but I can't figure out how to do vector graphics
                (fltk seems to be the Rodney Dangerfield of GUI toolkits, it
                 don't get no respect. Personally I like it but I have to be
                 able to draw arbitrary lines, polygons, circles etc. and 
                 I couldn't figure out how to do that with bb)
    ii. gtk - doesn't seem to be available
   iii. tk   - too slow for a handheld? Many folks seem not to like tk
   iv. Qt  - too clumsy and complicated to use for neophytes.
   v.  Fox, Widestudio, wxwindows, et. al. - no eggs available.
       I like Fox and use ruby fox a fair amount at work. An egg for Fox
       would be great.
   vi. build a gui on cairo, opengl (vincent(*) would be really cool) or sdl
        Yeah, right. Actually I'm really tempted to take a stab at this.
        tinyclos + widgets built on slick cairo graphics sounds cool.
        How hard could it be :-)
4. cross compile and package a gui - depends on #3
5. start writing some cool scheme apps for embedded devices

     Widestudio:          http://www.widestudio.org/

I would love to see all the bits of progress recorded on the wiki. It would 
be nice to have a place to put the various files (the .ipk files I have 
made for instance) to help people get going also.
