[RESOLU] compil avec lib pthread sous linux

compil avec lib pthread sous linux [RESOLU] - C - Programmation

salut,
j'ai écris un programme qui utilise la librairie pthread. Il se compile très bien sous Windows, mais pas sous Linux.
 
Voici ma ligne de compilation :
 

Code :
  1. gcc -g -Wall -o service main.c thread_clock.c thread_led.c thread_machine.c -I./postgresql-8.3.5/src/include/ -I./postgresql-8.3.5/src/interfaces/libpq/ -I./pthreads-w32-2-8-0-release/ -L./pthreads-w32-2-8-0-release/lib/ -L/usr/lib/ -lpq -lpthread -DDEBUG


 
et le résultat :
 

Code :
  1. In file included from ./pthreads-w32-2-8-0-release/pthread.h:288,
  2.                  from main.h:31,

  5. In file included from ./pthreads-w32-2-8-0-release/pthread.h:288,

J'ai vérifié plusieurs fois ma ligne de compil et les chemins, et tout correspond... Voyez vous l'origine de mon problème ?
 
Merci

Pouquoi tu inclues les headers ./pthreads-w32-2-8-0-release plutôt que ceux de /usr/include ? Vu le w32 dans le nom ils m'ont l'air d'être faits pour windows ceux là, non ?

Effectivement autant pour moi... J'ai aussi découvert que la fonction pthread_delay_np n'existait que pour win32, je l'ai remplacée par sleep() sous linux (sleep() est thread safe)
