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:

2) Now download the source code into your build environment:

3) Now we can port the package. First of all you should install (possible) all dependencies to build the package. At this stage the build system does now know anything about dependencies, install them manually:
| Code Block | ||
|---|---|---|
| ||
du3p01% cd apache2-2.4.43 du3p01% dpkg-checkbuilddeps dpkg-checkbuilddeps: error: Unmet build dependencies: debhelper (>= 10) bison jdupes libapr1-dev (>= 1.6.0) libaprutil1-dev (>= 1.6.0) libbrotli-dev liblua5.2-dev libnghttp2-dev libpcre3-dev libssl-dev (>= 1.1.1) libxml2-dev lsb-release zlib1g-dev libcurl4-openssl-dev | libcurl4-dev libjansson-dev |
4) Now you can try to install them:

The file is ready and we're preparing next file...
debian/control
This file is used to specify dependencies o build the package(sAlso 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):
| Code Block | ||
|---|---|---|

Build-Depends: debhelper-compat (= # 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.

You see it ad check stage.
...
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:
| Code Block |
|---|
# 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.
