<b>WARNING:</b> Accoring to this [http://talk.maemo.org/showthread.php?t=35122&page=2#19 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.

<i>NOTE:</i> Maemo ignores [http://de.wikipedia.org/wiki/Shebang shebangs] for shells and always executes shell scripts in busybox. You need to pass the script explicitly to any other shell:
 
 
<pre>
 
<pre>
bash ./test.sh
+
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 \

<b>WARNING:</b> Don't try to relink /bin/sh to /bin/bash. You system won't boot and you will have to reflash the device.
+
On default setups it will fail because of apt-get saving temporary files on the root partition.
<br>
+
Just clean the apt cache (<pre style="display: inline; padding: 2px">apt-get clean</pre>) and repeat the above command.
  
<i>NOTE:</i> Gnu coreutils and gnu grep are prefixed with the letter 'g'. Therefore you need to call <pre style="display: inline; padding: 2px">/usr/bin/gls</pre> to use gnu ls. For some third party scripts/builds to work properly you might need to create symlinks for the gnu tools to be used.
+
=== Fix scratchbox hacks ===
  
Example:
+
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.
<pre>
 
ln -s /usr/bin/ggrep /usr/bin/grep
 
</pre>
 
  
You might also create bash aliases for gnu utils.
 
 
$HOME/.bashrc aliases example:
 
 
<pre>
 
<pre>
# alias to gnu ls instead of busybux
+
mkdir -p /scratchbox/tools/
alias ls='gls --color=auto'
+
ln -s /usr/bin /scratchbox/tools/bin
 
 
alias ll='ls -l'
 
alias la='ls -la'
 
alias md='mkdir'
 
alias rd='rmdir'
 
 
 
# aliases to gnu grep instead of busybux
 
alias grep='ggrep'
 
alias egrep='gegrep'
 
alias fgrep='gfgrep'
 
 
</pre>
 
</pre>
  
=== Install build tools ===
+
linking bin seems to be enough.
 
 
<pre>
 
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
 
</pre>
 
 
 
On default setups it will fail because of apt-get saving temporary files on the root partition.
 
Just clean the apt cache (<pre style="display: inline; padding: 2px">apt-get clean</pre>) and repeat the above command.

You might want to install kernel headers:
 
<pre>
 
apt-get install linux-kernel-headers
 
</pre>

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

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.
