Problème avec GNU make qui ne reconnait pas mes "target"
Bonjour,
Je suis en train de développer sur plateforme embarquée et j'ai repris la bibliothèque Procyon ARMLIB.
Le makefile fournit avec les exemples fonctionne bien (modulo des problèmes de script pour le linker mais ce n'est pas le problème pour le moment).
Mon souci est que j'ai besoin d'apporter quelques modifications à au code car je ne peux pas utiliser directement ARMLIB. Or le makefile modifié (et presque identique à l'original) ne fonctionne pas.
Voici ce que j'obtiens :
Code:

make -C usart_example

make[1]: Leaving directory `/home/user/Projects/eclipse/workspace/test-serial/apps/usart_example'
