Erreur de génération de dépendances avec make

Question

J'essaie de mettre en œuvre la solution de création non récursive décrite dans l'article "Recursive Make Considered Harmful". Je suis actuellement bloqué pour obtenir les fichiers de dépendance * .d à générer. J'ai fourni le makefile, l'exemple module.mk et l'erreur ci-dessous. Des idées comment je peux résoudre ce problème?

Terminé Il semble que si un module ajoute types.cpp à SRCS, même si tel fichier source existe. En ce qui concerne les avertissements, la première fois que vous exécutez ce makefile, les fichiers de dépendance (foo.d) n'existent pas encore, alors Make se plaint qu'il ne peut pas les include eux. Ce n'est pas un problème, et les avertissements n'apparaîtront pas dans les exécutions suivantes lorsque ces fichiers existent à l'avance. Pour supprimer complètement les avertissements, remplacez include par -include.
