II. Compilation de libpod4

Dans le blog précédent, je vous ai montré comment on monte un iPhone/iTouch. Passons maintenant à quelque chose de plus sérieux.

Nous allons installer les paquets nécessaires à la compilation de libpod4. Ce qu'il faut juste savoir c'est que libgpod est une bibliothèque partagée pour accéder au contenu d'un iPod.


4. Installation des différents paquets nécessaires pour la compilation de libgpod4

Commençons par installer l'outil Git, qui est un logicile de gestion de version décentralisée. Par décentralisé, on entend que chaque personne peut développer son propre dépôt.

malagasy@malagasy-laptop:~$ sudo apt-get install git-core
The following extra packages will be installed:
libdigest-sha1-perl liberror-perl
Suggested packages:
git-doc git-arch git-cvs git-svn git-email git-daemon-run git-gui gitk
gitweb

Lors de l'installation du paquet git-core, d'autres paquets ont été suggérés à être installé, que je n'ai pas fait. Dans la suite de mes installations, je n'installe aucun autre paquet, sauf ceux que je vous vais vous indiquer.

Nous avons besoin d'installer les paquets suivant afin de pouvoir compiler le paquet libgpod4.

malagasy@malagasy-laptop:~$ sudo apt-get install autoconf libtool libglib2.0-dev intltool gtk-doc-tools sqlite3 libsqlite3-dev zlib1g-dev libxml2-dev checkinstall
The following extra packages will be installed:
automake autotools-dev cvs docbook docbook-dsssl docbook-to-man
docbook-xsl docbook-xsl-doc-html gettext gnome-common jade libltdl-dev
libruby1.8 libsp1c2 m4 ruby ruby1.8 sp
Suggested packages:
autoconf2.13 autobook autoconf-archive gnu-standards autoconf-doc psgml
docbook-defguide jadetex docbook-dsssl-doc libsaxon-java libxalan2-java
docbook-xsl-saxon fop xalan gettext-doc libtool-doc sqlite3-doc automaken
gfortran fortran95-compiler gcj ruby1.8-examples rdoc1.8 ri1.8

Puis installation du paquet libiphone-dev, puis de deux autres paquets optionnels libgdk-pixbuf2 et libgdk-pixbuf-dev pour pouvoir transférer des images (photos, couvertures d'album …).

malagasy@malagasy-laptop:~$ sudo apt-get install libiphone-dev libgdk-pixbuf2 libgdk-pixbuf-dev
E: Couldn't find package libgdk-pixbuf2

En effectuant quelques recherches sur le net, j'ai noté que “libgdk-pixbuf2″ et “libgdk-pixbuf-dev” sont inclus dans libgtk2.0-dev et libgtk2.0. J'ai effectué l'installation de ces derniers via synaptic puisqu'il m'est impossible des les installer via apt-get install.

Par contre, j'ai oublié d'installer le paquet libiphone-dev suite à cette erreur.


5. Compilation du paquet libgpod4

Pour compiler ligpod4, il faut taper les commandes suivantes :

$ git clone git://gitorious.org/~marcan/libgpod/marcan-sandbox/
$ cd marcan-sandbox/
$ git checkout origin/iphone30
$ CFLAGS="-g -O0" sh autogen.sh -prefix=/usr

En tapant ces commandes, je me suis apperçu par la suite qu'il me manquait des paquets, que j'installerai au fur et à mesure où cela est nécessaire comme vous pouvez le constater ci dessous.

malagasy@malagasy-laptop:~$ git clone git://gitorious.org/~marcan/libgpod/marcan-sandbox/

Configuration for libgpod 0.7.3SVN :
--------------------------------

Host System Type .........: i686-pc-linux-gnu
Install path .............: /usr
Preprocessor .............: gcc
Compiler .................: gcc -Wall -Wchar-subscripts -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wcast-align -Wsign-compare -Werror -std=c89 -g -O0 -Wno-strict-aliasing -Wno-sign-compare -Wdeclaration-after-statement -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/include/libxml2 -I/usr/include/gtk-2.0 -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
Linker ...................: gcc -lgobject-2.0 -lglib-2.0 -lsqlite3 -lxml2 -lgdk_pixbuf-2.0 -lm -lgobject-2.0 -lgmodule-2.0 -lglib-2.0
Artwork support ..........: yes
Python bindings ..........: no
PyGObject support ........: no
iPhone/iPod Touch support.: no

Now type 'make' to build libgpod 0.7.3SVN,
and then 'make install' for installation.

Now type `make' to compile libgpod

Comme vous pouvez vous attendre l'iTouch n'est pas supporté, vu que j'ai oublié d'installer le paquet libiphone-dev, par contre la prise en charge des pochettes est bien supportée.

Dans le prochain billet, je vous vous donnerai les résultats de la manipulation si on essaye de compiler libgpod à ce stade, ie comme indiqué ci dessus "iPhone/iPod Touch support.: no", puis de synchroniser l'iTouch.


6. Compilation du paquet libgpod4 (suite)

Nous allons maintenant installer le paquet libiphone-dev.

malagasy@malagasy-laptop:~/marcan-sandbox$ sudo apt-get install libiphone-dev
The following packages were automatically installed and are no longer required:
media-player-info
Use 'apt-get autoremove' to remove them.
The following extra packages will be installed:
libgcrypt11-dev libgnutls-dev libgpg-error-dev libplist-dev libplist1
libtasn1-3-dev libusb-1.0-0-dev libusbmux-dev
Suggested packages:
libgcrypt11-doc gnutls-doc gnutls-bin guile-gnutls

malagasy@malagasy-laptop:~/marcan-sandbox$ git checkout origin/iphone30
HEAD is now at f324198... Debug SHA1 payload

(...)
Configuration for libgpod 0.7.3SVN :
--------------------------------
(...)
Artwork support ..........: yes
Python bindings ..........: no
PyGObject support ........: no
iPhone/iPod Touch support.: yes

7. Installation de paquets supplémentaires, mais pas forcément nécessaires pour la compilation de libgpod4

Le non support de PyGObject m'a perturbé, et donc j'étais allé cherché les paquets nécessaires pour pouvoir le faire, qui sont python-gobject et python-gobject-dev.

malagasy@malagasy-laptop:~/marcan-sandbox$ sudo apt-get install python-gobject python-gobject-dev
The following extra packages will be installed:
libffi-dev python-dev python2.6-dev

malagasy@malagasy-laptop:~/marcan-sandbox$ CFLAGS="-g -O0" sh autogen.sh -prefix=/usr
(...)
checking for python development headers... found
checking for python module mutagen >= 1.8... no
(...)
Configuration for libgpod 0.7.3SVN :
--------------------------------
(...)
Artwork support ..........: yes
Python bindings ..........: no
PyGObject support ........: yes
iPhone/iPod Touch support.: yes

J'ai effectué l'installation du paquet python-mutagen via synaptic. Après quelques recherches, j'ai appris que Mutagène est un module Python pour manipuler des métadonnées audio. Il supporte les formats FLAC,M 4A, MP3, Ogg FLAC, Ogg Speex, Ogg Theora, Ogg Vorbis, True Audio, et les fichiers audio WavPack.

malagasy@malagasy-laptop:~/marcan-sandbox$ CFLAGS="-g -O0" sh autogen.sh -prefix=/usr
(...)
checking for python development headers... found
checking for python module mutagen >= 1.8... yes
checking for swig... no
configure: WARNING: cannot find 'swig' program. You should look at http://www.swig.org
(...)
Configuration for libgpod 0.7.3SVN :
--------------------------------
(...)
Artwork support ..........: yes
Python bindings ..........:
PyGObject support ........: yes
iPhone/iPod Touch support.: yes

J'ai ensuite installé les paquets swig & swig1.3 via Synaptique. Swig1.3 étant l'upgrade du paquet swig.

malagasy@malagasy-laptop:~/marcan-sandbox$ CFLAGS="-g -O0" sh autogen.sh -prefix=/usr
(...)
checking for swig... /usr/bin/swig
checking for SWIG version... 1.3.36
(...)
Configuration for libgpod 0.7.3SVN :
--------------------------------
(...)
Artwork support ..........: yes
Python bindings ..........: yes
PyGObject support ........: yes
iPhone/iPod Touch support.: yes

Now type 'make' to build libgpod 0.7.3SVN,
and then 'make install' for installation.

Now type `make' to compile libgpod

Maintenant que tout à l'air bon, on peut lancer la commande 'make'.

La suite dans le prochain billet.
