Gstreamer / Eclipse / Cross compilation

Bonjour à toutes et tous,

Je me tourne vers vous en espérant que vous puissiez répondre à mon problème.

Contexte :
Je souhaite développer une application utilisant gstreamer pour une cible embarquée à l'aide d'Eclipse et de la toolchain linaro. Malheureusement, après maintes tentatives, ça ne compile pas ... (la toolchain est opérationnelle, d'autre codes compilent mais utilisent des bibliothèques standards).

Voici mon code (qui est le Hello World de Gstreamer fourni sur leur site)

Le SDK de gstreamer est installé dans /opt/gstreamer-sdk. Ce qui est étrange c'est que l'autocomplétion fonctionne correctement.
Je suppose, en voyant le retour "error ld returned exist status" qu'il y a un problème de lien mais lequel ...

Merci de votre aide.
