Makefile : Suppression non désirée des .jpg créés.

Bonsoir à tous!

J'ai lancé des recherches sur google, lu la FAQ du forum et les règles du site et recherché sur le forum sans résultats, je me permets donc de créer un sujet.

Petite présentation : Je suis actuellement étudiant en informatique (ensimag pour ceux qui connaissent) et un projet de Makefile nous a été donné à faire. Nous venons juste de découvrire les makefile donc mes connaissances restent relativement faibles mais je pense avoir compris le principe. Je travaille sous Centos 6.5 64 bits.

But du projet : à partir d'un répertoire source contenant des images .jpg, il nous est demandé de créer une page index.html dans un répertoire /dest qui affiche ces images redimenssionnées.

Le problème : Tout fonctionne, j'ai bien vérifié avec

makefile dest/index -rRd 

sauf qu'au final, j'ai :

Successfully remade target file `dest/index.html'.
Removing intermediate files...
rm dest/black_texture_terminal_background.jpg dest/hot-keely-hazell-looking-sexy.jpg dest/images.jpg dest/youm.jpg

Make supprime donc mes images redimenssionnées du dossier /dest ce qui fait qu'en tapant :

firefox /dest/index.html

Rien n'est affiché puisque les images appellées par index.html ne sont plus dans le dossier /dest.

Ma question : Pourquoi make considère-t-il ces fichiers comme intermédiaires? J'ai cru comprendre qu'en effet, make supprimait les fichiers qu'il avait eu besoin de créer au fur et à mesure de la compilation mais ceux-ci sont explicitement créés par moi-même? Est-il possible de lui demander de conserver ces fichiers ou dois-je changer quelque chose à mon code?

Mon Makefile :

# Source and destination directories, to be configured here:
SOURCE=~/Pictures
DEST=./dest

IMAGES=${shell cd $(SOURCE) && echo *.jpg}
THUMBS=$(IMAGES:%=$(DEST)/%)
IMAGE_DESC=$(IMAGES:%.jpg=$(DEST)/%.inc)


# TODO
$(DEST)/%.inc: $(DEST)/%.jpg
 ./generate-[/contents/391-fichier-img img]-fragment_make.sh $< > $@ 

$(DEST)/index.html: $(IMAGE_DESC)
 ./generate-index.sh --html_head >> $@ ; \
 for k in $(IMAGE_DESC) ; do \
 ./generate-index.sh $$k >> $@ ; \
 done ; \
 ./generate-index.sh --html_tail >> $@ ; 


$(DEST)/%.jpg: $(SOURCE)/%.jpg
 convert $< -[/download/telecharger-34076712-resize resize] 200x200 $@

Descriptions des scripts du Makefile

generate-img-fragment_make prend en argument $1 une image.jpg et donne le code html nécessaire.
generate-index.sh donne le head et le tail du html avec --html_head et --html_tail et effectue un simple cat $1 dans les autres cas.

Le verbose complet du make :
