Lower price for N800 in Italy...maybe N810 coming closer?!

Posted on Thu 13 December 2007 in Linux, Maemo (EN) • Tagged with n800, nokia, tablet


I was looking in the Italian Nokia official shop, and I noticed that the N800 price was decreased to 259€ instead of 289€

You can verify it on the official website.

Maybe the N810 is coming closer? Who knows ;)

Installing Maemo SDK 4 Beta

Posted on Thu 25 October 2007 in HowTo, Linux, Maemo (EN), Programmazione • Tagged with maemo, nokia, SDK, tablet


Maemo is an opensource development platform for Linux based devices. Actually is the base for the operating system installed on Nokia N770, N800 and the upcoming N810 but it could be adopted, with few changes, even by other similar devices.

In particular, this version of Maemo SDK is the only one that allow developers to develop new applications for N810 and to start porting old application to this new platform.

The SDK is not only a set of libraries and compiler, it gives you a real environment that emulates the Nokia device, so the developer can write applications, debug them and test them. Both command line and gui application are supported in emulator.

Graphical environment is based on a real X server, a window manager and on GTK libraries, with a particular extension called Hildon.

With Maemo SDK you can:

  • Test Maemo applications using a normal PC with Linux.
  • Write and debug applications written by you.
  • Port existing applications written for Linux/GTK and verify if they work correctly.
  • Compile and build ARMEL package so you can install them in the device.


These are the minimum requirements to work with Maemo SDK:

  • Intel compatible processor (x86), at least 500 Mhz
  • 256 Mb RAM
  • 2 Gb space on hard disk
  • A Linux distribution (I suggest Debian or Ubuntu)

You need the following software packages:

Starting from 4.x version, Maemo has a simple installer script, so all you need are these two files:

Installing Scratchbox

The first tool you have to install is Scratchbox. I suggest you to use the script provided but you could choose also to install it manually (in this case please refer to this site for detailed instructions).

Before beginning the installation of Scratchbox, you have to become root.

First of all set the permission of the script file:

chmod +x maemo-scratchbox-install_4.0beta.sh

Then run it with these parameters:

./maemo-scratchbox-install_4.0beta.sh -d -u andy80

Please note that -d tells the installer to install from Debian dpkg packages while -u specifies your username (in my case is andy80, you have to change it using your local username).

Scratchbox environment will be installed in /scratchbox/

Please note that you'll have to logout and login again to be able to log into you new Scratchbox environment. To test it you simply have to start Scratchbox from your local user:


Welcome to Scratchbox, the cross-compilation toolkit!

Use 'sb-menu' to change your compilation target.  
See /scratchbox/doc/ for documentation.

Installing Maemo SDK

When Scratchbox is correctly installed on your system, you can install the Maemo SDK. Please note that you have to do it from normal user (the user you specified in the installation of Scratchbox).

Simply run this command and follow instructions:

bash maemo-sdk-install_4.0beta.sh

At the end you should get this message:

Installation was successful! ----------------------------

IMPORTANT! Please read this.

You now have the maemo 4.0beta 'chinook' installed on your computer.  
You can now start your maemo SDK session with /scratchbox/login and  
then select your target with 'sb-conf select SDK\_BETA\_ARMEL' for the  
armel target or 'sb-conf select SDK\_BETA\_X86' for the i386 target.

If you have any problems with targets' package databases, you can try  
running 'fakeroot apt-get -f install' on your scratchbox target.  
This command will try to fix any problems with the package database.

Happy hacking!

Installing Xephyr

Xephyr is an X11 server that provides a device screen for the developer so that you can see all the maemo application windows and visuals on your computer.

To install it in a Debian based distribution, simply execute this (from root):

apt-get install xserver-xephyr

Running Xephyr

To see if all works fine, you should start Xephyr and Maemo environment. Execute this from outside the Scratchbox environment:

Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac -extension Composite

Now, from another shell, log into Scratchbox and execute this:

[sbox-SDK_BETA_X86:~] > export DISPLAY=:2 
[sbox-SDK_BETA_X86:~] > af-sb-init.sh start

This should start the Hildon Application Framework inside the Xephyr window. That's all!
