> Q1. What do I do to turn ON optimization for pentium ? I'm not sure that egcs has any specific pentium optimisation flags. You might want to look at pentium gcc (pgcc) which does have some specific pentium optimisations. > i compiled my kernel with egcs, it's smaller now and seems to run > faster. > i compiled /usr/src/bin with egcs so > > Q2. why /bin/cat compiled with egcs is _bigger_ than /bin/cat ? > is it Ok ? what did I miss ? Err you used a different compiler, you shouldn't be surprised that the exectuable sizes may be slightly different. > Q3. why 'man cc' says me about gcc-2.7.1 ? Check your MANPATH variable. This is the path searched for manual pages by man. You'll find that the man page for the system cc occurs earlier in this path. -- Greg Lewis glewis@trc.adelaide.edu.au Computing Officer +61 8 8303 3237 Teletraffic Research Centre To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
