The easiest way to get started is to install the SDK stuff from Irex. A post on
mobileread.com helped me to get going:

Thanks jharker!

The relevant steps are:

cd /tmp; mkdir sdk; cd sdk
wget http://developer.irexnet.com/pub/iLiad/Toolchain/oe-sdk-20071004091648.tar.bz2
tar xvfj oe-sdk-20071004091648.tar.bz2
sudo mv usr/local/arm /usr/local/arm
sudo mv usr/lib/ipkg /usr/lib/ipkg

For env:

################## setup_build_env.sh ####################

#!/bin/bash
# Edit these paths to point to the location of the OE SDK
export PATH=/usr/local/arm/oe/bin:/usr/local/arm/oe/arm-linux/bin:$PATH
export PKG_CONFIG_PATH=/usr/local/arm/oe/arm-linux/lib/pkgconfig

The Irex components have a script build_all_from_scratch.sh. These do what they
say [:-)]. The might do more than you want… Below are the short-cuts I use

********** building a lib:

example: libergtk

.  setup_build_env.sh
./configure --host=arm-linux --build=i686  --prefix=/usr/local/arm/oe/arm-linux
make
make install

This installs the library in the SDK for further use.


************ building an app:

example: contentLister

.  setup_build_env.sh
autoreconf --install --force
./configure --host=arm-linux --build=i686  --prefix=/usr --datadir=/usr/share
make

possibly: strip -s <binary file>


notes:
    * no make install!
    * for this example: with the original SDK you need to build libergtk and
      liberregxml first
    * after the initial build, 'make' is enough to rebuild
