For the sake of cleanness, I will use: $(MAKE) --directory=source CPPFLAGS='' CFLAGS='$(CFLAGS)' With this, I erase the arch-specific options which should anyway not be in CPPFLAGS, and I use the Debian CFLAGS instead. I will benchmark the program later to see if O3 is really needed... Have a nice day, -- Charles Plessy -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
