If you are using an honest-to-goodness Opteron, and a relatively recent gcc, you should be using -march=opteron, as I am, unless you build binary packages to install on non-Opteron systems. Opteron = MMX, MMX2, SSE, SSE2, SSE3, 3dNow!, 3dNow! something else, plus scheduling optimizations for Opteron and maybe some other things I'm not remembering. -- If there's one thing we've established over the years, it's that the vast majority of our users don't have the slightest clue what's best for them in terms of package stability. -- Gentoo Developer Ciaran McCreesh pgpw7dirb0JSU.pgp Description: PGP signature

In fact there seems to be a fair bit of confusion on this.
I suspect my /etc/make.conf is wrong in several ways.
First let me explain: I switched computers due to my main linux box
giving up the ghost. I grabbed an athlon64 +3400 running winxp and
pirated it for my main gentoo desktop.
I switched over lots of stuff from the salvaged HDDs to the athlon.
Not sure now what I may have edited into /etc/make.conf. Somehow I
still got some amd stuff in it. probably from a 'from scratch
install' using a stage.
Anyway cutting to the chase I have this in there, I added everthing
below ALSA_CARDS I think:

this stage
# Please consult /etc/make.conf.example for a more detailed example

Note that I am NOT running 64bit gentoo but 32bit gentoo on this
athlon64.
It shows architecture as athlon xp which it is not. That is also 64
bit but from what I understand is still different than athlon64.
The xp mobos etc are cheaper, and not socket 754 I don't think.
Mine is socket 754 with K8V mobo chipset K8T800. I'm guessing that is
where the `k8' comes from.
I've been running with above make.conf with no (noticed) problems for
about 2 mnths. But now updating so would like to get it right.
So do you know if:
CFLAGS=-Os -march=athlon-xp -pipe
is wrong?
And if I wanted to run ACCEPT_KEYWORDS=~XXX keeping in mind I'm not
running 64bit gentoo, what would the `XXX' be?

maybe that was my misunderstading..on a brand-new opteron 64-bit...the
architecture use flag i use is k8. I see no real reason to run 32-bit
gentoo on a 64-bit box...64-bit support in gentoo was why we switched
distros when we switched to 64-bit servers. my -march is k8 for those
boxes. again, that's with a 64-bit opteron...if you're running
something else, you might need a different flag. i believe, to your
last question, it would still be i386.

OK, to cut short the confusion, Harry, your march setting in your CFLAGS should be k8, and the ACCEPT_KEYWORDS should be either x86, or ~x86, depending on if you want to run stable.

Thank you James. I was beginning to wonder if those settings were involved in the glibc problem you were helping with in another thread. Do you mind pointing me to the source of that answer? Also, I'm wondering if when I change the march setting to k8 in the mindle of an update world what that might do. It may be a good time to do it but I wonder if I need to do anything to already compiled updates. -- gentoo-user@gentoo.org mailing list
