HowTo SimpleDeb
Describe How a SimpleDeb looks like
And how you can create your own Debian packages for Maemo.
Autopsy of 'some-gnu-utils_0.1_arm.deb' (available from ApplicationCatalog Wiki):
user@linux:/tmp> ar -vx some-gnu-utils_0.1_arm.deb x - debian-binary x - control.tar.gz x - data.tar.gz
Yes, it is an ar-archive, not a tar-archive.
'debian-binary' must be the first file in this archive:
user@linux:/tmp> cat debian-binary 2.0
'control.tar.gz' just contains a single file:
user@linux:/tmp> tar -xvzf control.tar.gz control
user@linux:/tmp> cat control Package: some-gnu-utils Version: 0.1 Section: unstable Priority: optional Architecture: arm Depends: maemo Installed-Size: 1085 Maintainer: Armin M. Warda <Armin.Warda AT Web.De> Description: some GNU utilities for Maemo that I miss on my Nokia 770: wget 1.10.2, bc 1.06, find, xargs 4.2.25, gcal 3.01
You can determine the installed size with the 'du -k' command before packaging.
'data.tar.gz' must contain relative path names (no leading '/'), but remember, installation will occur relative to '/var/lib/install/', e.g. 'usr/bin/bc' will be installed to '/var/lib/install/usr/bin/bc':
user@linux:/tmp> tar -xvzf data.tar.gz usr/ usr/bin/ usr/bin/bc usr/bin/find usr/bin/gcal usr/bin/wget usr/bin/xargs
To save space, please strip-off debug information from executables and libraries before packaging, this can be done with the 'strip' command:
user@linux:/tmp> file usr/bin/* usr/bin/bc: ELF 32-bit LSB executable, ARM, version 1 (ARM), for GNU/Linux 2.0.0, dynamically linked (uses shared libs), stripped usr/bin/find: ELF 32-bit LSB executable, ARM, version 1 (ARM), for GNU/Linux 2.0.0, dynamically linked (uses shared libs), stripped usr/bin/gcal: ELF 32-bit LSB executable, ARM, version 1 (ARM), for GNU/Linux 2.0.0, dynamically linked (uses shared libs), stripped usr/bin/wget: ELF 32-bit LSB executable, ARM, version 1 (ARM), for GNU/Linux 2.0.0, dynamically linked (uses shared libs), stripped usr/bin/xargs: ELF 32-bit LSB executable, ARM, version 1 (ARM), for GNU/Linux 2.0.0, dynamically linked (uses shared libs), stripped

...also simple to build one!
You can easily reverse this process to build a package.
create a subdir for everything under /var/lib/install you intend to install, including links.
Everything relative to /var/lib/install. Add debian-binary and modify the control file.
Then run the following script:
#!/bin/sh tar -zcvf data.tar.gz ./usr ./etc tar -zcvf control.tar.gz control rm winzig_1.71-N770v0.1_arm.deb ar q winzig_1.71-N770v0.1_arm.deb debian-binary control.tar.gz data.tar.gz ar t winzig_1.71-N770v0.1_arm.deb ls -al winzig_1.71-N770v0.1_arm.deb
To see another example of the files, check this one: winzig-1.71_N770_source.tar.gz

- here's a link to a package for ar for your N770: http://www.sia.huaral.org/download/ar-maemo-0.1.deb
Created with the following little script. (After actually bootstrapping with ar from the binutils package for arm.)
#!/bin/sh PACKAGE=ar-maemo VERSION=0.1 DIRS="usr" find $DIRS| grep \~ && rm -i $(find $DIRS| grep \~) SIZE=$(du -sc $DIRS|grep total|sed s/total//) echo "Package: $PACKAGE Version: $VERSION Section: unstable Priority: optional Architecture: arm Installed-Size: $SIZE Maintainer: Kasper Souren <kasper DOT souren AT gmail DOT com> Description: ar from GNU binutils " > control cat control tar -zcvf data.tar.gz ./usr ./etc tar -zcvf control.tar.gz control NAME=$PACKAGE-$VERSION.deb rm $NAME ar q $NAME debian-binary control.tar.gz data.tar.gz ar t $NAME ls -al $NAME
