AMD AM2 Dual-Core 6000+ Question

[kpep01]

I've decided to seek a bit of adventure and go in over my head (again). The new box has an AMD AM2 Dual Core 6000+ on it. I'm presently downloading the iso for the AMD 64, figuring that will do the trick.

My question will be in setting a couple of my make parameters.

I'm assuming I should go:

CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=athlon-xp -pipe -02"
CXXFLAGS="[CFLAGS]"
MAKEOPTS="-j3"

I'm assuming -j3 since it is a dual core processor.

I get a bit confused in the documentation as it says the above utilizes 64-bit, while another part of the documentation (albeit a bit old documentation) says to use march=k8.

The fact is, this system will be "surrounding" a Win2k network (for those that can't handle a real computer in the office). So, maybe 64-bit will screw things up when it comes to running printers, etc through cups and samba.

If I'm wrong (or if there are different things to consider) , please correct me before I screw myself.

Thanx.

Hi

You should set -march=k8 or -march=athlon64, not athlon-xp, in your CFLAGS. You are correct about using -j3 for a dual-core processor.

Good luck!

Thanx for the notes, sternklang. I greatly appreciate it.

You should go with CFLAGS="-march=athlon64 -msse3 -O2 -pipe". You could even go -O3 instead of -O2 (note that's a letter O, not a number 0), which I personally use. You can also up your makeopts to -j4 or -j5. And I'd add LDFLAGS="-Wl,-O1".

This 64-bit system will not screw up the network functionality at all, that's completely transparent.

Thanx for the hints, yngwin.

I'm comparing my current make.conf to the one I'm creating in order to streamline from my past stupidities.

I've not used LDFLAGS before, so, it's total unknown to me. I'll have to learn something more about that one, but, in the mean time I'll give it a go. If I'm reading correctly, -WI is a capital "eye."

Two inputs have said that CFLAGS should be -march=athlon64, so, I'm using that plus the extra little tricks from yngwin. I guess I need to study a bit more sometime to understand what all of this sage advise really means.

Thanx to both yngwin and sternklang for your input to my learning curve.
