Familiar project

Currently Familiar's Linux distribution supports some of the following key features
- Entirely based on XFree86's/keithp's Tiny-X server, which includes the latest RENDER extension.
- Anti-Aliased True-Type Font support in rxvt, ion, blackbox, and fltk (this is extended to any X application using the Xft APIs).
- OpenSSH's ssh and sshd included by default.
- The latest releases include JFFS2 supported, which enables you to have read/write access to the iPAQ's Flash.
- Integrated Python v2.0 w/ PyGtk and PyGDKImlib.
- Binary and Library compatible w/ Debian's ARM distribution. In most cases, programs (as long as their dependencies are met) can be taken from Debian and executed on the iPAQ w/out issue.
- Full package support based on ipkg.

ARM cross-compilation

CrossCompiler notes for setting up a toolchain
Linux ARM http://www.tazenda.demon.co.uk/phil/armlinux/
Linux ARM toolchain / cross-compiler http://www.tazenda.demon.co.uk/phil/arm-tools.html
ARM compiler from LART project http://www.lart.tudelft.nl/lartware/compile-tools/

  export CC=arm-linux-gcc
  ./configure --enable-speed --enable-fpm=arm --enable-sso arm-linux
  make

iPAQ kernel compilation - from the CRL CVS
http://cvs.handhelds.org/cgi-bin/viewcvs.cgi/linux/kernel/arch/arm/def-configs/ WWW CVS access to e.g. .config file (use with: make oldconfig)
using standard CVS tools

       export CVSROOT=:pserver:anoncvs@cvs.handhelds.org:/cvs
      # # Password: anoncvs
      cvs checkout -r {tag} linux
      e.g.: cvs checkout -r K2_4_6-rmk2-np1-hh2 linux
      make mrproper
      # this removes e.g. version.h (check this file later if unsure)
      cp arch/arm/def-configs/h3600-familiar .config
      make oldconfig
      # CONFIG_EXTRAVERSION="-fam4" (don't forget the -)
      make bzImage

Cross-compile hints

add the option: –with-tools=/path/to/cross-compiler/prefix-for-gcc- for example, if your cross-gcc were /usr/arm/bin/arm-linux-gcc, then you'd use the option “–with-tools=/usr/arm/bin/arm-linux-” (with trailing dash - the commands gcc, cl, g++, … will be appended to this option's value!)
make sure, it doesn't try to link the host-platforms libraries.
you have to add the options: –with-fgllib=../../fgl –with-ipllib=../../ipl (the values for the options are the defaults, so perhaps you might omit them)
stripping executables: arm-linux-strip hello-world

StrongARM kernel compilation

General list of patches for various ARM machines http://www.arm.linux.org.uk/developer/machines/
cross-compiled gcc must be at correct place (e.g.: /opt/arm-cross-gcc, just setting the PATH is not sufficient and results in complaints about components not found)

it is possible to make a terminal connection to the ipaq (running linux) if the usb-net kernel module is installed to enable ethernet over usb. (needs more details!)
