Bonjour,  
je sais le titre n'est pas très clair.
Voici mon problème dans le cadre d'un projet "pile réseau Java sur Linux".  
Je veux modifier la couche Ethernet de Linux et donc la recompiler et l'intégrer. A chaque fois que je tente un gcc, linux me renvoie à des erreurs dans les librairies .h qui sont pourtant les siennes (linux/random.h par exemple).  
 
Que pensez vous de cette erreur ?
 
 
 
 
 
PS : peut etre que ce topic serait mieux dans programmation ?

je pense oui, surtout que sans les erreurs on va pas aller bien loin

En effet
voici Donc :
 
cd /usr/src/linux-2.6.3/net/ethernet
make pe2.o
 
et voila le resultat

sans avoir toucher à pe2.c auparavant, c'est donc l'original de la pile Linux

tu as déjà programmé avant ?
