Oki, i see
man ar said :
     "ar  is  considered  a  binary utility because archives
of this sort are
      most often used as libraries holding commonly needed
subroutines."

So, i have to compile all my .o, put them together into a .a
archive and finally link this archive into the executable
file with -l option ?
Does an "ar" command can be placed in a makefile?
Thanks !
