Configurer les sources des paquets

1. OpenWrt possède système de management des paquets.
2. OpenWrt propose un dépôt logiciel, contenant actuellement (2015-sept) la liste suivante pour Chaos Calmer http://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/packages/, soit plus de 2000 paquets !
3. D'autres projets de dépôts additionnels existent.
4. Pour installer/désinstaller des paquet, veuillez vous reporter à la documentation dédiée : opkg.

Les paquets officiels d'OpenWRT se trouvent dans le dossier “packages” de votre version d'OpenWRT installée ici : http://downloads.openwrt.org/

Veillez à bien choisir les dépôts qui correspondent à la version installée sur votre matériel !

Exemple de fichier /etc/opkg.conf pour la dernière version stable (de la branche “ar71xx”) Chaos Calmer 15.05 :

dest root /
dest ram /tmp
lists_dir ext /var/opkg-lists
option overlay_root /overlay
src/gz chaos_calmer_base http://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/packages/base
src/gz chaos_calmer_packages http://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/packages/packages
src/gz chaos_calmer_luci http://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/packages/luci
src/gz chaos_calmer_routing http://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/packages/routing
src/gz chaos_calmer_telephony http://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/packages/telephony
src/gz chaos_calmer_management http://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/packages/management

Each package feed is in a separate directory

• packages
• telephony
• routing
• management
• oldpackages

Other feeds are available but have no package repository. Examples: alljoyn, luci2

Packages can be divided into three categories:

• containing shell scripts only - architecture-independent
• normal packages (binaries) - architecture-dependent
• kernel packages (kmod-*) - kernel version specific

Trunk: Installing kernel modules requires often a reflash/sysupgrade because the build revision changed (it gets recompiled every few days automatically).

Each release has its own directory containing sub-directories for the different platforms supported, each platform-directory contains pre-built images for the different targets and a packages directory containing the installable *.ipk files.

Here are some examples of OpenWrt package repositories for different compilation targets and OpenWrt versions.

• Barrier Breaker 14.07 packages for generic ar71xx platform can be found at: https://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/generic/packages/
• For the snapshot-release and ar71xx platforms you find them here: http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/. While the other repositories are mostly not updated, the packages in the trunk repositories are continuously built by the OpenWrt build bots. Beware with upgrading packages, since some (kernel) packages are made for the specific OpenWrt build built at the same time as the package.

opkg install http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/umurmur-polarssl_0.2.6-1_ar71xx.ipk

Stable Version: Source tar-balls for most packages can be found at http://downloads.openwrt.org/sources/ and http://mirror2.openwrt.org/sources/.

Trunk: Found at the PKG_SOURCE_URL from the package Makefile in the corresponding feed.
