ALWAYS CREATE A BACKUP BEFORE TINKERING WITH YOUR N900

ON-Device - Getting Started

WARNING: Accoring to this post, installing packages from the SDK repository to your device might cripple the root fs and force you to reflash it. Anyway, the maemo scratchbox environment is awful and for small builds it is more convient to build directly on the device. Packages mentoned in this guide don't seem to cause serious problem.

Prerequisites

• First Steps

Add tools and sdk to /etc/apt/sources.list

# TOOLS
deb http://repository.maemo.org/ fremantle/tools free
deb-src http://repository.maemo.org/ fremantle/tools free

# SDK
deb http://repository.maemo.org/ fremantle/sdk free
deb-src http://repository.maemo.org/ fremantle/sdk free

Update apt cache:

apt-get update

Install build tools

apt-get install bzip2 cpio cpp dpkg-dev g++ g++-4.2 gcc \
libc6-dev libstdc++6-4.2-dev libstdc++6-4.2-dbg patch \ 
perl perl-modules autoconf automake1.9 libtool flex bison \ 
gdb diffutils-gnu

On default setups it will fail because of apt-get saving temporary files on the root partition.

Just clean the apt cache (

apt-get clean

) and repeat the above command.

Fix scratchbox hacks

The tools from the SDK and TOOLS repository are meant for scratchbox and have been altered to use scratchbox paths. Instead of rewriting paths you can fake scratchbox directory structure.

mkdir -p /scratchbox/tools/
ln -s /usr/bin /scratchbox/tools/bin

linking bin seems to be enough.

Using strace on the phone

Make sure you added TOOLS and SDK repositories to your sources.list and install strace.

apt-get install strace
