Configuring the Compile Options

[throdon]

hey decided to restart and am comfortable so far here is where I get all confused, I am at section 5.d Configuring the Compile Options of the handbook
my ect/make.conf:

CFLAGS="O2 -pipe'
CXXFLAGS="-O2 -pipe"

CHOST="x86_64-pc-linux-gnu"

USE="mmx sse sse2"

should I change my CFLAGS to 'CFLAGS="-march=nocona -O2 -pipe" ' and my CXXFLAGS should they read exactly the same or can I make my CXXFLAGS read 'CXXFLAGS="${CFLAGS}" '

next question with 'MAKEOPTS="-j3" ' . I am going with -j3 because it's one more than the amount of cpus, does it matter where in /etc/make.conf or does it have to be on a certain line.

CFLAGS, well, what cpu is it? And yes you can have CXXFLAGS="${CFLAGS}".

next question with 'MAKEOPTS="-j3" ' . I am going with -j3 because it's one more than the amount of cpus, does it matter where in /etc/make.conf or does it have to be on a certain line.

MAKEOPTS can be placed on its own line anywhere in make.conf as far as I know.

my cpu is "Intel (R) pentium(R) Dual CPU T3400 @ 2.16GHz as per the command "cat /proc/cpuinfo"

and I know it's x86_64 as per "uname -a"

x86_64 as per "uname -m"

upon further review I have decided to set my CFLAG="-march=native -O2 -pipe" because my cpu's are not a true Core2 and as far as I have found this should configur it automaticly for my arch.
so thank you all you have been a great help and on to the next step.
