Prepare build environment
Add unstable repo to /etc/apt/sources.list
deb https://apt2.dilos.org/dilos dg3-unstable main contrib non-free deb https://apt2.dilos.org/dilos du3-unstable main contrib non-free deb https://apt2.dilos.org/dilos dg2-unstable main contrib non-free deb https://apt2.dilos.org/dilos du2-unstable main contrib non-free deb-src https://apt2.dilos.org/dilos du3-unstable main contrib non-free deb-src http://mirrors.kernel.org/debian/ buster-updates main contrib non-free deb-src http://mirrors.kernel.org/debian/ buster-proposed-updates main contrib non-free deb-src http://mirrors.kernel.org/debian/ buster-backports main contrib non-free deb-src http://mirrors.kernel.org/debian/ buster main contrib non-free
To build packages into a new repo (du3) we need to use old build environment based on du2, but new packages should come from the new repo, that is why we placed du3 above du2 in the list.
deb-src lines instruct apt where it should get upstream source packages. In our example it is buster (a codebase of debian). Add an architecture:
add architecture:
dpkg --add-architecture amd64
And update the data:
update existing packages:
apt-get update
Perhaps you will see key errors due to update stage something like this:

This means you should add these public keys to the system. Do it as:

Install build packages:
install packages:
du3p03% apt-get install gmake build-essential
If you want to build some package from an existing repo you need to install git to clone the repo:
install git
du3p01% sudo apt-get install git
Now clone a repo (du3), at this stage you have created an account at bitbucket and ask to provide you access by info: http://www.dilos.org/conact-me
clone repo:
du3p03% git clone https://bitbucket.org/dilos/du3.git
go to components directory:
cd du3/components
you are ready to build your package from userland, for example: apt
cd <du3>/components/p0f gmake JOBS=4 deb (JOBS is the number of parallel build processes you want to use)
After the building process is done, you find the built package(s) in <du3>/components/${component}/build directory
How to port a new package
1) Choose a package you want to port. For example, apache2. Go to the debian packages page at https://packages.debian.org/buster-backports/apache2 and copy the correct name of the source package in the right column ("Download Source Package apache2:"). Remember (or copy) "apache2". Install additional packages to manipulate the source code:

Well, done. Now we are ready to port the package to our platform.
There are three files (or more) you should check.
debian/changelog
This file controls the target package version and the repo you wnat to place the binary packages to. Let's see at the structure:
changelog

- -- Joao Eriberto Mota Filho <eriberto@debian.org> Wed, 15 Jul 2020 17:56:23 -0300 - who made the changes and when
We add a new record to the file on top (like the LIFO or stack).
changes in changlog
jdupes (1.18.1-1~bpo10+1+dilos1) unstable; urgency=medium * Build for DilOS. -- DilOS Team <dilos@dilos.org> Mon, 10 Aug 2020 12:06:57 +0300 jdupes (1.18.1-1~bpo10+1) buster-backports; urgency=medium * Rebuild for buster-backports. -- Joao Eriberto Mota Filho <eriberto@debian.org> Wed, 15 Jul 2020 17:56:23 -0300
As you see we added +dilos1 to the version (to mark our changes), the repo now is unstable (if you plan to contribute the result to the main repo), the message says it is a build for DilOS and the last line shows who did the changes. To generate the date just use date -R command in the shell:
date -R
du3p03% date -R Mon, 10 Aug 2020 12:06:57 +0300
Also you can use the template created by gmake debgenlog command, go to your local copy of the du3 repository, and than components/<any_component> (apt for example):
# cd <path_to_du3>/du3/components/apt # gmake debgenlog /ws/home/akozlov/du3/tools/deb_gen_log.pl dummy (1.2.3.4) unstable; urgency=low * build for dilos -- DilOS Team <dilos@dilos.org> Sun, 31 Jan 2021 22:08:33 +0300
Here you just need to change name and version of the component.
The file is ready and we're preparing next file...
debian/control
This file is used to specify dependencies o build the package(s):
dependencies
Build-Depends: debhelper-compat (= 13)
You see it ad check stage.
Also the file contains list of the producced packages and their architechtures:
packages and architectures
Package: jdupes
Architecture: any
Multi-Arch: foreign
Depends: ${misc:Depends}, ${shlibs:Depends}
Description: identify and delete or link duplicate files
/*** cut ***/
Built package will have name jdupes (as the source package). Architecture any means for any platform. It could be:
- any - for any architectures (binary package)
- all - for all plafroms (documentation, configurations etc)
- linux-any - platform specific package (in this example for linux only), we cannot build such packages (as is)
In this example we don't need to change anything, just leave it as is.
debian/rules
Speaking shortly it is a Makefile that is used to build all target packages (from the contol file, using version from changelog). Usualy the file contains valid options to build packages for our platform, but from time to time you need to change something. For example, gnu ld accepts -Wl,-as-needed option, illumos ld does not, just remove this option from the list. Other cases are too specific to describe them as example, just ask us on #dilos at FreeNode or via the mail list.
debian/pre* and post* scripts
Another stuff is he pre/post scripts, probably you should change them (if package has them). Our platform should be able to bootstrap zones, it means the packages could be installed into an alternative root. For this purpose we use BASEDIR environment variable to specify it (it comes from apt/apt-get). Let's take an example from reprepro package:
postinst
desktop% pwd
/export/home/denis/projects/dilos/du3/components
desktop% cat reprepro/debian/postinst
#!/bin/sh
set -e
if [ "${BASEDIR:=/}" = "/" ]; then
BASEDIR=""
fi
case "$1" in
configure)
if [ -f ${BASEDIR}/etc/bash_completion.d/reprepro.dpkg-remove ] ; then
echo "Removing obsolete unmodified conffile /etc/bash_completion.d/reprepro"
rm -f ${BASEDIR}/etc/bash_completion.d/reprepro.dpkg-remove
fi
;;
esac
#DEBHELPER#
exit 0
If we install the package as is (in the current environment) the BASEDIR is "/" and we just clear it.
quilt patch
If during the porting process you need to change something outside the debian folder, then these changes must be placed in the dilos.patch:
# quilt new dilos.patch # quilt add <modifying_file> # quilt refresh
du3/components/<package>
When the porting has done and all packages built you should place it into the du3 repo. Create a directory (usualy by the source package name), in our examples it is apache2 and/or jdupes.
make directory
du3p03% mkdir -p du3/components/jdupes
Create the Makefile to build the package by CI (jenkins):
Makefile
du3p01% cat du3/components/jdupes/Makefile
