Porting / Creating packages

If you're looking at creating your own package, or porting software, the first things to do are:

  1. Check if someone already ported the package (if it in the repository? Is there an issue for it?)
  2. Check if there already are Debian packaging scripts/files. Debian packages a LOT of software, so it's likely that the software is already in the Maemo repository, or someone at least has build scripts for it.
  3. (TODO)

Porting existing Maemo Fremantle packages

Maemo Fremantle ("Nokia Maemo for the N900") contains a lot of packages that are open source. Most of them should run with very few changes on Maemo Leste, the main changes you will need to make will be:

  1. Check if someone already ported the package (if it in the repository? Is there an issue for it?)
  2. Updating of the Debian packaging files/scripts.
  3. Porting to newer libraries if old libraries are used (OpenSSL 0.9.8 -> OpenSSL 1.1.x, Qt4 -> Qt5, etc)
  4. Fixing any compile errors/warnings due to more strict compile flags

Source of the packages can be found at one of these places:

Example

Getting the source package

Let's say we'd like to port a package "msid".

it's here: 

http://repository.maemo.org/extras/pool/fremantle/free/source/m/msid/

get the latest version: 

wget http://repository.maemo.org/extras/pool/fremantle/free/source/m/msid/msid_0.4.8-2.tar.gz

tar zxvf msid_0.4.8-2.tar.gz
cd msid-0.4.8

Creating new repo

init a git repo: 

git init
git add *
git commit -a -m "initial commit from fremantle sources"

change content of `debian/compat` to `9`.

edit 

debian/changelog

.

let's say the last release was: 

msid (0.4.8-2) unstable; urgency=low

now the release should be: 

msid (0.4.8-2+leste1) unstable; urgency=low

record your changes, add your name.

look if 

debian/control

dependency versions should be changed.

installing build dependencies

sudo apt build-dep .

building

dpkg-buildpackage -b -uc

add 

gbp.conf

file in 

debian

directory with the following content: 

[DEFAULT]
upstream-tag=%(version)s

in 

debian/control

file add (if not added) 

XSBC-Bugtracker: mailto:yourname@yourserver.am

icon

and the icon (this is not necessary if you port existing maemo5 package).

it is done this way.

you need to have `optipng` installed. (media-gfx/optipng in gentoo).

  • prepare a `48x48` png file.
  • optimize it: 
    optipng -strip all
  • base64 encode it
uuencode -m maeFat.png maeFat.png > maeFat.png.base64
  • Add the field 
    XB-Maemo-Icon-26
    to your 
    debian/control
    (in Maemo 4 the size of the icons was 26×26 pixels, hence the name of the field, which has not changed in Maemo 5)
  • Open the 
    base64
    version of your image and copy from the line under 
    begin-base64 644 <name of 48×48 image>
    to the line above the 
    ===
    .
  • Add this to the XB-Maemo-Icon-26 field
  • Add a space in front of every line of the encoded icon. You can do that automatically using sed when you base64 encode the image:
uuencode -m <name of 48×48 image> <name of 48×48 image> | sed -e s,^,\ ,  > <name of 48×48 image>.base64

cli apps

if the program that is being ported is a cli application, then cli icon can be used.

cli icon announcement

old unexistent in archive.org too, txt file

icons as images

this is how the icon looks in ham:

Maemo-cli icon appman sample v002.png

and this is the 48x48 size icon:

Maemo-term icon v002 a001 48p.png

its base64 encoded and shifted for maemo text file is here

or here: 

 begin-base64 644 maemo-term_icon_v002_a001_48p.png

Also add the field: 

XSBC-Maemo-Display-Name: Photo light meter

pushing to maemo-leste-extras

go to maemo-leste-extras and open an issue in the extras bugtracker repo to request a repository.

ping Wizzup on #maemo-leste@irc.libera.chat to open you repo[s]. then try to be attentive to emails, because you may get github invite which you need to accept, otherwise it’ll time out(not sure when).

push your code to the newly opened repo in maemo/beowulf branch.

beowulf is the codename of the devuan release on which maemo is based.

the repo needs to be tagged. 

git tag 0.0.1

and then the tag has to be pushed: 

git push maemo 0.0.1

in case you did some changes but don’t want to bump a tag/changelog version, you need to delete the tag locally: 

git tag -d 0.0.1
git push maemo :refs/tags/0.0.1

phoenix

login https://phoenix.maemo.org/

the build sequence is:

  • source
  • binaries
  • repos

find your project. let’s say https://phoenix.maemo.org/job/msid-source/

it has to have ‘build with parameters’ button on the left.

if everything is right it’ll trigger build of binaries https://phoenix.maemo.org/job/msid-binaries/

that link, for instance, will contain arm64 build console output: https://phoenix.maemo.org/job/msid-binaries/architecture=arm64,label=arm64/1/console
