Usually I dot my laptop with READMEs in various ~/devel/ subdirs, but in this case I decided to write up some notes here. These are mostly for my own reference, but perhaps they will be of use to you.

=Debrick=

Too mucha programmaz
I bricked my N900 by adding the extras-testing + extras-devel repos and then installing lots of applications. I hit 100% on / (root filesystem) and on reboot the system hung at the "dots" part, ala:

* (*) * * *

I had filled up to 100% a number of times before and rebooting the phone had cleared up space (e.g. 100% full before reboot, 96% full after reboot). This is likely because 5% or so is reserved for root. Anyway, the most recent time it didn't come back alive...

Flashing N900 with 0xFFFF
Many parts of the N900 are Free Software, but lamentably, many parts are still closed proprietary shit. Nokia's maemo_flasher program is an example of a closed application that Nokia makes for use with the N900. I understand why some parts of their suite are still closed (e.g. pre-ofono GSM stack), but why the flasher has to be closed I have no idea. Gar.

Thankfully, there is The 0pen Free Fiasco Firmware Flasher, which is designed for flashing Nokia tablets and is Free Software (GPLv3). Unfortunately, 0xFFFF doesn't work with the N900. There is some progress to support the device. You can grab the most recent code from the mercurial repository thusly: hg clone http://hg.youterm.com/0xFFFF

I sent the author of 0xFFFF the output of my crash. Hopefully it will soon be a usable tool for flashing the N900. I built RPMs for Fedora 12 x86_64 running the latest mercurial code--the ones in the Fedora repo aren't even the lastest tarball release (0.3.9 vs. 0.4.0).


 * The 0xFFFF GUI uses gtkamlc. This is not packaged in Fedora. I built it, but compiling the GUI is still barfing.

Flashing with Nokia's Proprietary maemo_flasher
I now have ONE non-free program installed on my computer :(   It's the only way I know how to debrick the phone.

See also: Updating tablet firmware on this wiki.

yum -y install glibc.i686 libusb.i686 ./flasher-3.5 -F ~/devel/maemo/FLASH/RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin -f -R
 * To get the most recent image from Nokia, go here: http://tablets-dev.nokia.com/nokia_N900.php
 * Enter product ID inside the phone (without "/"s)
 * Grab RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin or whatever is current.
 * To get the proprietary stinking pile of poo, go here: http://tablets-dev.nokia.com/maemo-dev-env-downloads.php
 * Grab maemo_flasher-3.5_2.5.2.2.tar.gz or most recent.
 * In Fedora 12 x86_64 I had to install some i686 libraries since my system is 64-bit. So:
 * Untar the files....
 * Power off phone and unplug USB.
 * Hold down "u" on N900 keyboard and plug in USB cable between computer and N900. A USB icon will appear in the upper right corner--you can let go of "u" on the keyboard at this point.
 * Run this as root:
 * Done.

Info from flasher
sudo ./flasher-3.5 --query-rd-mode flasher v2.5.2 (Oct 21 2009) USB device found found at bus 002, device address 008. Found device RX-51, hardware revision 2101 NOLO version 1.4.13 Version of 'sw-release': RX-51_2009SE_1.2009.42-11_PR_MR0 The device is in production mode

Unpacking flash image
$ mkdir RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM-UNPACKED $ cd RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM-UNPACKED/ $ sudo flasher-3.5 -u -F ../RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin

=Setup= Now that the device is debricked, I can use the thing again and "all" my data is there, but the repository setup is back to default and the applications I want are gone, amongst other things. To re-setup:

ssh server & keys
ssh root@burger ssh localhost scp -p ~/.ssh/id_rsa.pub root@burger:.ssh/authorized_keys ssh root@burger vi /etc/passwd user:!: to user:*: passwd user su - user rm .ssh/known_hosts ssh localhost exit exit ssh user@burger
 * Enable Extras repository: tap, tap, tap...
 * Install openssh client/server package
 * Install rootsh package
 * Set up keys and such for easy access (my device hostname is burger):
 * On laptop, ssh into the sucker:
 * As root on N900, ssh to localhost as a quick/dirty way to setup /root/.ssh:
 * On laptop, copy over ssh key and log back in:
 * To allow ssh access for user "user", the passwd file needs to be edited.
 * Change
 * Set a password for user "user" (I couldn't ssh in without doing this, but someone on IRC said it wasn't necessary):
 * Switch user to "user" and blow out the old known_hosts (or at least edit it) to remove the now bogus "localhost" entry:
 * Quick/dirty way to set up /home/user/.ssh:
 * Then GTFO:
 * This should work happily

Set up Repositories
deb https://downloads.maemo.nokia.com/fremantle/apps/ ./ deb https://downloads.maemo.nokia.com/fremantle/mr0 ./ deb http://repository.maemo.org/extras/ fremantle free non-free deb http://repository.maemo.org/extras-testing/ fremantle free deb http://repository.maemo.org/extras-devel/ fremantle free deb http://repository.maemo.org fremantle/tools free apt-get update
 * Configure the repositories to set up things I like:
 * 1) vi /etc/apt/sources.list.d/hildon-application-manager.list

Apparently the above gets blown out if you run the hildon application manager, so the repos need to be added via tap tap tap.

Install Needed Packages
apt-get install x11vnc apt-get clean && sync

Mas y mas y mas

apt-get install vim bash htop ogg-support less file strace apt-get clean && sync

Perhaps

apt-get install python-dbus python-gobject apt-get clean && sync

Configuration
Here's some configuration settings that got lost on reflash. I'm not sure where they are stored, so they need to be re-setup via tap tap tap. Note: if you do a backup on the device you may be able to then run restore which refreshes this, making the below unnecessary; untested.

Display

 * Settings-->Display-->Backlight time-out: 2 minutes
 * Settings-->Display-->Lock screen automatically: uncheck
 * Settings-->Display-->Display stays lit when charging: check

Text input

 * Settings-->Text input-->Word completion: uncheck
 * Settings-->Text input-->Auto-capitalization: uncheck
 * Settings-->Text input-->Insert space after word: uncheck
 * Settings-->Text input-->2nd language: Español (América Latina)
 * Settings-->Text input-->Use dual dictionaries: check

Time Zone

 * Settings-->Date and time-->Time Zone: Buenos Aires (this is unfortunately wrong due to incompetence of Argentine government)
 * Settings-->Date and time-->Update automatically: leave unchecked for now. When timezone data gets fixed, check it.

Connectivity

 * Settings-->Connectivity-->Internet connections-->Search interval: 5 minutes

General

 * Settings-->General-->Device lock-->Change lock code (default is 12345)

Email Accounts

 * Region: Argentina
 * Service Provider: Gmail -- I broke down and got a gmail acct :(
 * Account title: Gmail
 * Name: Jeff Moe
 * User name: jebbasan
 * Password: foo

Misc
echo ":syntax on" > ~/.vimrc

export TERM=xterm-color
 * Uh, where should this be put, if no bash? In ~/.profile for busybox.

[hildon-welcome] You could also put in a different movie (playable by gstreamer), but a still image will not work.
 * To remove the overcute hands shaking at bootup (and therefore boot faster), edit /etc/hildon-welcome.d/default.conf thusly:
 * 1) filename=Hands-v32-h264.avi

=Kernel= Stock kernel: uname -a Linux Nokia-N900-42-11 2.6.28-omap1 #1 PREEMPT Wed Oct 28 15:32:55 EET 2009 armv7l unknown

kernel, kernel-modules, kernel-flasher: 2.6.28-20094102.3+0m5

Compile custom kernel
I followed the procedure in the Maemo Kernel Guide, without making changes. This gave me a bootable kernel. :)

sb-conf select FREMANTLE_ARMEL sb-conf setup MaemoKernel \ -c cs2007q3-glibc2.5-arm7 \ -d qemu:perl:svn:apt-https -t /scratchbox/devkits/qemu/bin/qemu-arm-sb sb-conf select MaemoKernel sb-conf rs MaemoKernel \ /home/jebba/maemo-sdk-rootstrap_5.0_armel.tgz mkdir ~/maemo_kernel sb-conf select MaemoKernel fakeroot apt-get update cd ~/maemo_kernel apt-get source kernel cd kernel-2.6.28 make EXTRAVERSION=-omap1 bzImage ls -lh arch/arm/boot/zImage flasher-3.5 -f -k /scratchbox/users/jebba/home/jebba/\ maemo_kernel/kernel-2.6.28/arch/arm/boot/zImage
 * 1) disable other stuff in apt sources.list
 * 1) flash the thing
 * 1) wow, sure flashes fast, like in 1 second

To unbrick if something goes wrong, unpack the main N900 .bin flash image and flash with the kernel from there. See unpacking flash image section.

Random kernel notes
~ $ cat /sys/power/sr_vdd1_autocomp 0 ~ $ cat /sys/power/sr_vdd2_autocomp 0
 * "SmartReflex can perform continuous dynamic voltage scaling around the nominal operating point voltage according to silicon characteristics and operating conditions. Enabling SmartReflex reduces power consumption. Please note, that by default SmartReflex is only initialized. To enable the automatic voltage compensation for VDD1 and VDD2, user must write 1 to /sys/power/sr_vddX_autocomp, where X is 1 or 2.


 * Enable framebuffer console so bootup messages can be seen.


 * linux-omap mailing list archives

=VNC= VNC allows you to view the screen of the N900 on your laptop so you can do things more easily that having to use the tiny little thing if you are working on it all day.

x11vnc -storepasswd
 * Set up the Extras-testing repository
 * Install x11vnc (I think it's in -testing).
 * Set up a password for VNC on on the N900:
 * Run this script on your laptop (my hostname is burger and my laptop's IP is 10.0.0.3):

ssh -n user@burger \ "x11vnc \       -usepw \        -display :0 \        -desktop burger \        -allow 10.0.0.3 \        -nolookup \        -q \        -bg \        -o /home/user/vnc-log \        "
 * This works fine with tigervnc on Fedora 12.


 * Running x11vnc with "-ssl" does not work--I think the problem there may be with tigervnc as x11vnc starts with it OK.


 * I usually do VNC in an ssh tunnel--I don't know if this would create too much of a load on the N900 or not. Will test.


 * VNC behaves differently whether the keyboard is slid out or not. Basically, you want the keyboard out.

=Backups= Thankfully, pre-bricking, I had made a backup. There are a billion different ways to do this, but one quick way is good old rsync. This script backs up everything except the --excluded directories which are either things I don't want to back up (cities) or things you can't/shouldn't back up (/proc).

rsync \ -avv -ult --progress --stats \ --rsh=ssh \ --exclude /home/user/MyDocs/cities \ --exclude /home/user/MyDocs/.sounds \ --exclude /proc \ --exclude /dev \ --exclude /sys \ --exclude /syspart \ root@burger:/ \ /home/jebba/BACKUPS/burger/
 * 1) !/bin/sh

=Video=

Encoding Video
I had some video which played way too slow on the N900, so I re-encoded with this pile of cruft:

mencoder $1 -oac mp3lame -ovc lavc \ -lavcopts vcodec=mpeg4:mbd=1:vbitrate=300 -vf scale=352:208 \ -ffourcc DIVX -o $1-out.avi Run thusly:
 * 1) !/bin/sh

burger-encode ralf.mov

And it will give you "ralf-out.mov.avi"...Uh, I will have the output file get a reasonable name, of course... Works for now. This does not work on the N900 at the moment because the mencoder in the mplayer package is compiled without mp3lame support. Bah.

See also (where I got above from): Manual_video_encoding.

Ok, here's a far better script than the above that I took and slightly modified to work with gpac instead of mp4creator.

# # _INFILE="$1" _OUTFILE="$2" _MPOPTS="$3" identifySource {  mplayer -identify -ao null -vo null -endpos 2 ${_MPOPTS} "${_INFILE}" | grep ID_ > /tmp/n800-encode.$$.ident FPS=$(cat /tmp/n800-encode.$$.ident | grep ID_VIDEO_FPS | uniq | cut -d '=' -f 2) ASPECT=$(cat /tmp/n800-encode.$$.ident | grep ID_VIDEO_ASPECT | tail -n 1 | cut -d '=' -f 2 | cut -d ' ' -f 2) WS=`expr $ASPECT \> 1.6 \& $ASPECT \< 1.9` if `expr $ASPECT \> 2.0` -eq 1 then WS=2 fi  case ${WS} in     0) SCALE="320:240"       echo "encoding for standard"       ;;     1) SCALE="400:224" echo "encoding for widescreen" ;;    2) SCALE="400:192"       echo "encoding for extra-widescreen"       ;;   esac } encode {   x264 -o "$PWD/n800-encode.$$/video.264" "$PWD/n800-encode.$$/video.y4m" --threads 3 --no-cabac --bitrate 250 -A i4x4,p4x4,p8x8,b8x8 --level 1.2 >/dev/null 2>/dev/null &   faac -b 96 --mpeg-vers 4 -o "$PWD/n800-encode.$$/audio.aac" "$PWD/n800-encode.$$/audio.wav" 2>/dev/null >/dev/null&   sleep 1   mplayer -vf scale=${SCALE},unsharp=c4x4:0.3:l5x5:0.5 -ao pcm:file="$PWD/n800-encode.$$/audio.wav" -vo yuv4mpeg:file="$PWD/n800-encode.$$/video.y4m" -ass -embeddedfonts -noframedrop ${_MPOPTS} "${_INFILE}"   rm -f "${_OUTFILE}"   MP4Box -new -add "$PWD/n800-encode.$$/video.264" -add "$PWD/n800-encode.$$/audio.aac" -fps ${FPS} "${_OUTFILE}" } prepareTemp {   mkdir -p "$PWD/n800-encode.$$"   mkfifo "$PWD/n800-encode.$$/video.y4m"   mkfifo "$PWD/n800-encode.$$/audio.wav" } cleanupTemp {   rm -Rf "$PWD/n800-encode.$$" rm -f /tmp/n800-encode.$$.ident } trap cleanupTemp SIGINT SIGTERM identifySource prepareTemp encode cleanupTemp

mplayer
Play video from main "good" back camera: mplayer tv:// -tv device=/dev/video0

Play video from front camera (next to screen): mplayer tv:// -tv device=/dev/video1

Note, the front camera looks absolutely terrible like there is far too much gain or something and has a huge band across the right side. I'm hoping this is just a kernel driver issue and it will contain less suck in the future.

=DBUS=

Here's a number of dbus examples that can be run as simple shell scripts. When running them they should be run with `run-standalone.sh` in front of them to set up the environment correctly. Otherwise they may barf when run from cron, startup, install scripts, etc. They run fine when run as user "user" without `run-standalone.sh`. Example: run-standalone.sh dbus-send /foo bar 'boo'

=Gripes=
 * Not all Free Software....
 * 256M of NAND is way too little if it is going to be the root filesystem (/). It is way to easy to fill up. I see that they need to do this for reflashing, but since on reflash all the applications in /opt get lost anyway, what good does it do to have them there? Seems they could have mounted /usr on the 32G, or even better just put /boot on NAND and in that case NAND could even be smaller. Seems very dumb to have 32G+ of space on the device, yet still fill up the rootfs! The vast majority of users are going to have no clue how to repartition (which I will do here shortly) and aren't going to be able to install many applications, which should be a great strength of this device since it can multitask so well and the repositories are going to blossom
 * 4 rows of keys would have been a lifesaver.
 * No | (pipe) or tab key
 * The camera doesn't autofocus, or at least not when you need it to.
 * When charging the phone and talking on it, the power cable is sticking out the top, not the bottom.
 * No dictionary/translation program (!)
 * Docs, info, contacts, etc. are spewed all over the place. For instance, try to find out info about Canola. Some on this wiki, some in garage, some at their site, etc. Where does one file a bug? I've been told to ignore garage and do most at *.maemo.org, but then they should ditch those parts at garage to make things cleaner.
 * SDK pretty much assumes you are running 32-bit Debian or Ubuntu. It's not really cooperating nicely in a Debian Lenny install inside qemu.

=Bugs=

Broken

 * After reflash, extra apps are still in /opt, but are "missing" since the symlinks from /usr/bin are gone.
 * More steps needed - which exact apps, did you restore from Backup? --andre


 * Saving preferences in xchat crashes.
 * I can confirm this, but I don't know if the Maemo port of xchat has a separate bugtracker in garage.maemo.org  --andre

`rm -rf ~/.cache/midori ; rm -rf ~/.config/midori`       Start midori. Go to some website. Click "Tools". Click "Clear Private Data". Check "Clear private data when quitting Midori" (but DON'T click "Clear private data" button). Tap blurry part at top to close private data window. Exit Midori. `ls -R ~/.cache/midori/web` and see the .pngs or whatever.
 * "Clear private data on exit" in Midori doesn't actually clear ~/.cache/midori/web (!). I spoke to packager (kalikiana) on IRC and he said he would look into it.


 * `less`, `vim` etc. don't see to like $TERM=rxvt-unicode. Using $TERM=xterm-color works fine. Probably not worth filing a bug...
 * vi is available via default, but not vim. Feel free to file a bug report with exact steps. --andre


 * lcuk: package liqcontrolpanel's summary is "short description". Package should be removed entirely.


 * Image viewer: 1) rotate image 2) view thumbnail. Image doesn't get rotated in thumbnail in *some* cases.


 * Maps viewer (OVI): The program is running ok in Spanish, but map data is in English (e.g. "South Pacific Ocean" "South America"). I first ran the program in English, but have subsequently set the system to Spanish.

RFEs

 * Alarm clock should show current time, not time alarm was set for, or when you hit snooze, you can't see current time (and think it is alarm time!).


 * Package manager can only install one package at a time (in contrast to how synaptic does it, for example).
 * https://bugs.maemo.org/show_bug.cgi?id=601 . Feel free to vote. --andre


 * In package manager you have to keep scrolling down to the package you want. You can't just hit "r" for example and have it scroll to "r" in the list of packages. This is actually pervasive throughout Maemo 5. It seems to only really do this in Contacts app.
 * https://bugs.maemo.org/show_bug.cgi?id=5388 . Feel free to vote. --andre


 * It totally sucks that if someone steals your phone, they pretty much own you. At least /home/user/MyDocs should be encrypted. Ideally this would be done with LUKS and decrypt at boot with a password. Perhaps encryptfs
 * https://bugs.maemo.org/show_bug.cgi?id=6030 is related for Mail storage - feel free to file a new enhancement request --andre


 * In Contacts app, it always shows a SMS button for phone numbers, even if they are landlines.
 * https://bugs.maemo.org/show_bug.cgi?id=6375 - probably WONTFIX for convenience reasons --andre


 * Need a #maemo-devel channel too, as #maemo is noisy...


 * xchat is totally not tweaked for maemo, such as scrolling...

echo "ao = pulse" > ~/.mplayer/config
 * mplayer should use pulsebarfaudio by default, not alsa:


 * Media Player doesn't thumbnail videos after they are taken with the N900 camera/video app. It didn't after closing and re-opening app, but I see they are now thumbnailed (post flashing). Anyway, it should do them "immediately".


 * Lots of internationalization packages are taking up space needlessly. But if, for example, Swedish Calendar support is removed, it wants to remove the whole calendar. The i10n packages should be removable without removing the whole app.


 * OGG support out-of-the-box. I mean, c'mon now...
 * Political reasons - see https://bugs.maemo.org/show_bug.cgi?id=176 --andre

Bugs of Note
Here's a few bugs of interest to me. Please vote for them. :)

No Source Code

 * Provide source for libspeex, libspeexdsp

Builder

 * Publishing packages to garage.maemo.org oftens results in "lost connection" and "permission denied" from scp


 * Would be great if it would be possible to see build log of in-progress build


 * We need servers

Argentina Time Zone

 * Buenos Aires, Argentina time off by 1 hour
 * Inital setup time zone: America Latina only lists cities in Mexico

Calendar/Tasks

 * RFE: Show calendar when selecting dates in Tasks/Calendar
 * Provide bi-daily/weekly/monthly recurrences
 * Add option to select multiple days on weekly repeating events.
 * Add relative day option for monthly repeating events (e.g. "1st Monday of month")
 * Day picker shows no daynames - hard to enter recurrence for e.g. 5 days only

Chat & Call & SMS

 * Zoom in/out in IM chat does not reflow contents ("Carolina's bug")
 * Google Talk Video Chat crash & lack of interoperability

Contacts

 * Contacts: Provide "Fax" field(s)
 * Edit/Rename field names or being able to add remarks

wiki

 * clicking on wiki username *edits* their page instead of viewing it

lsb-core

 * No getopts, called by init-functions (lsb-core) - breaks `/etc/init.d/asterisk start` (asterisk 1.6)

ringtones

 * Assign a ring tone and ring volume on a per-contact level

=Custom Packages=

Packages Done
I have set up a package repository. To use it you need to add my repo. In the application manager, add it thusly (I'm translating from Spanish, so the words may be slightly different.

 * Components

Burgerspace
sudo apt-get update ; sudo apt-get install burgerspace /usr/games/burgerspace
 * Fantastic. Heh.
 * Workz.
 * You have to install with apt, as it won't show up in the Applications Manager
 * Built deps libgengameng4c2a libgengameng-dev for it.
 * You gotta launch it from the command line for now...
 * No sound.
 * Is aligned left, not center.
 * Press spacebar to begin.

Asterisk
Source3: asterisk-sound-en.tar.gz %setup untar %source3 or whatever I'm not sure how to do that in .debs, but I'll figure it out. Another option is to just do a completely separate package, but that is not how Debian does it. I'm kind of surprised the debian method runs off and wgets them, but I need to look closer. Anyway WORKSFORME, I can call the phone and the sample voice menu picks up and such. That uses about 5% of CPU (compare with how much pulseaudio uses playing a song which is like 3x that). At some point I'll grab some of the choice config bits from BLASTERISK which will be fantastico.
 * asterisk! - I have asterisk 1.6.1.11 up and running. I built packages for them (which build fine in my scratchbox), but they failed on the build server (...hours later...). The problem is the weird way that asterisk packages the sounds. It runs off and wgets/curls them from Digium's site during the build. In a asterisk.spec, I would just do like:

Connected to Asterisk 1.6.1.11-1 currently running on Nokia-N900-42-11 (pid = 2120)

Packages TODO
Package these or get someone to do it.


 * colordiff
 * fantasdic - dictionary
 * git
 * some video conferencing app (telepathy-gabble), jingle etc.


 * tangogps - "an easy to use, fast and lightweight mapping application for use with or without GPS."
 * Babiloo - offline dictionary
 * Take a look at the various OpenMoko (OpenSnot) applications
 * boa - lightweight webserver (cute)
 * lshw

=SDK= There are a couple different SDKs (at least) that can be used. I have the main/standard SDK up and running on Fedora 12 x86_64. It is based on Scratchbox 1. There is another SDK, Maemo SDK+, which is based on Scratchbox 2, but I don't have that working yet.

Free Development Box

Running Maemo 5 SDK on Fedora 12 x86_64
Now that the SDK is happily installed, you can run it.

New Group sbox
In the terminals where you will be running commands you need to run this to show up in the sbox group. Any subsequent times you log out and in you don't need to run it again (in other words, you just have to run this when you first set things up): newgrp sbox

Start Scratchbox & Xephyr & Login
After installation scratchbox is "booted" up. Subsequently (e.g. after a reboot of your laptop) you will need to start it thusly: sudo ~/devel/maemo/scratchbox/sbin/sbox_ctl start

Get Xephyr going, which is the X server. Note the Fedora 12 version doesn't have the "-kb" optioned mentioned in other docs. Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac

Log in to Scratchbox: ~/devel/maemo/scratchbox/login

This should give you a prompt like this: [sbox-FREMANTLE_X86: ~] >

Then to launch the emulated GUI, run this at the above prompt: af-sb-init.sh start

Then you should have the emulator up and running! :)

Frequently Used Commands
Build binary package: cd foo-1.2.3 dpkg-buildpackage -rfakeroot -b -uc

Build source package: cd foo-1.2.3 dpkg-buildpackage -rfakeroot

Switch to build for ARM: sb-conf select FREMANTLE_ARMEL

Switch to build for x86: sb-conf select FREMANTLE_X86

Kill off things running if it won't let you switch between ARM/x86: sb-conf killall

Grab and start building a source package: apt-get -b source foo

File that describes package being built: vim foo-1.2.3/debian/control

File that has build rules (e.g. where ./configure is): vim foo-1.2.3/debian/rules

File that lists patches to be used: vim foo-1.2.3/debian/patches/series

Source Repositories
One of the "easiest" ways to get things built is to just check to see if it is in any of the Debian repositories and just pillage it from there. Grabbing it from an "old" repository and building it will be easiest because the dependencies are more likely to be the same. Grabbing it from the latest and greatest repository means you will get the most recent version of the package, but will probably have to go through and sort out more dependencies.

Note, you (or I) probably don't want to add the binary repositories to your build environment or you may cause some total chaos in your system. In this case, I am only adding the source repositories.

These are the source repos I added to /etc/apt/sources.list. Note that you have to do this within both architectures (x86/ARM) as they don't share the same sources.list.

Some of the same repos above are listed twice, just to help me keep straight all of Debian's releases. For example "sid" and "unstable" are the same thing. Explanation:


 * Etch - This is what the SDK is based on. It was released in 2007. Version 4.0. ("oldstable").


 * Etch Backports - These are packages which aren't in Etch, or at least not updated to the latest and greatest in Etch, but people "outside" of the Debian project maintain more recent packages. For example, they may have a more recent version of a web browser when Debian's Etch just backports patches to an ancient version.


 * Lenny - This is the "stable" version of Debian. Version 5.0. Released February 2009.


 * Squeeze - This is the "testing" version of Debian and when it is fully done will be the "stable" release and will be version 6.0.


 * Sid - This version will never be stable nor "released" and is always on the bleeding edge. The latest, most recent packages are in this repository. This is like "rawhide" in Fedora and -current in OpenBSD.

maemo-optify
QUICK NOTE (XXX FIX):

From: Marius Vollmer  Jeff Moe  writes: > I installed the maemo-optify 0.2 package from extras-devel but it is missing > the maemo-optify-buildpackage script. I see it in git. Ahh, right. The maemo-optify-buildpackage script is not used any longer. I have removed it from Git to reduce the confusion. The real dpkg-buildpackage in the SDK has been modified directly to call maemo-optify.

Tools to make using /opt convenient for Debian packages. git clone git://gitorious.org/maemo-af/maemo-optify.git
 * maemo-optify README

Maemo-optify is available in the repos and you can apt-get it from within scratchbox, but the .deb is missing the maemo-optify-buildpackage script. I emailed the author to let him know. In the interim, grab it from git, and: cp -p maemo-optify-buildpackage /usr/local/bin

To use it is super-simple, and worked for me without hassle with asterisk: echo auto > asterisk-1.6.1.11/debian/optify maemo-optify-buildpackage -rfakeroot -b -uc maemo-optify-buildpackage -rfakeroot -S

Uh, I also want files of all sizes to be moved to /opt, not just ones above 2048 bytes. Asterisk has 600k of files still, since it has lots of sound files smaller than 2k. There is a forthcoming option to define this in debian/optify, but that feature isn't in place yet. So in the interim remove the maemo-optify packages (from both X86 and ARM), and use this "patch":

--- maemo-optify/maemo-optify	2009-12-04 21:30:51.770927951 -0300 +++ /usr/local/bin/maemo-optify	2009-12-06 17:39:22.000017316 -0300 @@ -127,7 +127,7 @@        dbg "link, nope\n"; } elsif (!

Configure Scratchbox environment
Within scratchbox: echo ":syntax on" > ~/.vimrc echo ":set paste" >> ~/.vimrc echo ":set nobackup" >> ~/.vimrc echo "export TERM=xterm-color" >> ~/.bashrc

I still feel like a total noob sometimes in that I don't even know how to get my fkn Home/End keys to work in the scratchbox. heh. Hint anyone? :)

SDK Errors
If you get this: ERROR: Scratchbox is not properly set up!

Run this: sudo /scratchbox/sbin/sbox_ctl start

SDK+
This is the "alternative" SDK based on Scratchbox 2. I don't have it working yet on Fedora 12 x86_64. It complains and says it just works on i386 ARCH.

Maemo SDK+ - Alternative SDK for Maemo based on Scratchbox 2.

http://maemo-sdk.garage.maemo.org/maemo-sdk-installer.py chmod +x maemo-sdk-installer.py sudo ./maemo-sdk-installer.py install -g

Hmm. Well, this is crashing and burning on x86_64:

$ sudo ./maemo-sdk-installer.py install -g Operating system's machine or word size (x86_64) is not supported. These are supported: ['i386', 'i686'] System check failed!

Things possibly needed: yum -y install redhat-lsb

debootstrap
Perhaps I should install this sucker in an etch chroot...
