Hi all, |
| 2 |
|
| 3 |
I have a Core2Duo T5600 1,83 MHz in my notebook. Today I read on the |
| 4 |
GentooWeeklyNewsletter to use "-march=nocona (and an amd64 profile) for Core |
| 5 |
2 Solo/Duo" |
| 6 |
|
| 7 |
Currently I'm using: |
| 8 |
CFLAGS="-O2 -march=pentium-m -pipe" |
| 9 |
CHOST="i686-pc-linux-gnu" |
| 10 |
CXXFLAGS="${CFLAGS}" |
| 11 |
MAKEOPTS="-j3" |
| 12 |
and |
| 13 |
/usr/portage/profiles/default-linux/x86/2006.1/desktop/ |
| 14 |
as profile and gcc -v told me I'm using 4.1.1-r1 |
| 15 |
|
| 16 |
Now my questions: |
| 17 |
1. What wold be the benefits of chanching the CFLAGS? |
| 18 |
2. After chanching do I have to emerge everithing again? or what should I |
| 19 |
do? |
| 20 |
3. They mentiont to use a amd64 profile, does this mean to use 64bit? |
| 21 |
because I would like to stay with 32bit. |
| 22 |
4. I used gcc -v to check the gcc verison I'm using, is this the rigth |
| 23 |
command? |
| 24 |
|
| 25 |
Thanks for any help |
