I would like to propose the following to you:

I write 'a brief step by step instruction of what to do after you have 
compiled an application running on the Nokia', I send this to you,
you try it, add missing details, and finally you add the resulting 
'idiot proof step by step command line series of what to do after you 
have a compiled an application running on the Nokia' to the Wiki.

You understand, this Maemo and Wiki is about collaboration...

OK, here we go:

After you compiled your application you have all resulting files 
prepared. Executables, libraries, config files, and everything else 
is prepared, and just has to be packaged into a deb for installation 
on the Nokia 770.

You might have to adapt the config files of your application because 
on the Nokia 770 finally everything will be installed relative 
to /var/lib/install/, for example /etc/myconfig 
becomes /var/lib/install/etc/myconfig. If your application has 
compiled-in locations, you might even have to change Makefiles, or 
source files before you compile!

mkdir ./stage
cd ./stage
mkdir bin etc lib libexec sbin usr var # only those which you need

Create necessary subdirectories below ./stage/usr/

Move the files into the appropriate directories.

Do a 'strip' on the executables and libraries to remove debugging 
information and reduce size.

It does not really make sense to include source code, READMEs, manual 
pages, etc. into the package for the Nokia 770, so just ignore these.

du -ks .  # note down the size to put it into the control file

cat > control <<EOF
Package: my-package-name
Version: 0.1
Section: unstable
Priority: optional
Architecture: arm
Depends: maemo
Installed-Size: 12345
Maintainer: My Name <My.Name at My.Mail.Server>
Description: this application does bla bla bla
EOF

Edit the file. Put in the correct size you just determined.

echo 2.0 > debian-binary
tar -cvzf control.tar.gz control
tar -cvzf data.tar.gz ./usr

ar -rv my-package-name_0.1_arm.deb \
  debian-binary control.tar.gz data.tar.gz

Good Luck! Send me a mail after you updated the Wiki!

  regards, Armin.
