 |
|
Hi,
can anybody suggest what I should use in the /etc/make.conf as CFLAGS etc. for a Intel Core 2 Duo T9400 to yield optimal performance? The cpu is 2.53GHz and the 6MB cache and 4GB (2 x 2GB, DDR-3 1066MHz) RAM.
Thanks. |

Hi, you can you this :
| Code: |
CFLAGS="-O2 -march=nocona -pipe"
CHOST="x86_64-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="-j3"
|
On my box, I use that :
| Code: |
CFLAGS="-O2 -march=nocona -pipe"
CHOST="x86_64-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="-j5"
GENTOO_MIRRORS="http://distfiles.gentoo.org"
USE="gtk kde -gnome qt3 qt4 kdeenablefinal nls oss alsa dvd dvdread dvdr truetype avi userlocales cups
foomaticdb usb divx ppds unicode jpeg gif png mp3 opengl mpeg real xv quicktime hal dbus pdf"
LINGUAS="fr"

d2_racing,
what does CHOST="x86_64-pc-linux-gnu" mean? Does it refer to a 64bit box? I am actually not sure if I have 32 or 64 bit...
And can I use
FEATURES="ccache"
CCACHE_SIZE="6G"
in my case? |

Hi, yes you can use
| Code: |
FEATURES="ccache"
CCACHE_SIZE="2G"
|
but you need to actually install ccache before adding these lines to your /etc/make.conf

Hi, your CPU is a 64 bits compatible, so you can install your Gentoo box with the AMD64 CD or the SystemRescueCD and boot with the rescue64 options 
Good luck |
