    ok from what I read, this is the best flag setup for my processor. Someone tell me if I should do something different.

    CHOST="i686-pc-linux-gnu"
    CFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer"
    CXXFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer"

    I use -O2 myself, -O3 turns on some more loop optimisation, but produces bigger binaries. -O2 seems to be a good compromise.

    How big are we talking here? The hard drive is pretty big, if it runs faster with a slightly bigger binary, well I'd rather the speed.

    My make.conf essentialy looks like this:

    Code:
    USE="X gtk samba qt cups foomaticdb ppds usb"
    CHOST="i686-pc-linux-gnu"
    CFLAGS="-march=athlon-tbird -O3 -pipe -fforce-addr -fomit-frame-pointer -funroll-loops -falign-functions=4 -maccumulate-outgoing-args -mmmx -m3dnow"
    CXXFLAGS="${CFLAGS}"
    GENTOO_MIRRORS="http://gentoo.ccccom.com http://open-systems.ufl.edu/mirrors/gentoo ftp://mirrors.tds.net/gentoo http://mirror.tucdemonic.org/gentoo/"
    My gentoo computer is my personal server, and is equipped with an athlon thunderbird 800mhz, 120g HDD, and 256mb of ram. It functions primarily for samba file/printer sharing (hence the need for USB, cups, and foomaticdb.) It's also handy for the following: SSH, a BNC server, a VPN endpoint, video processing/conversion, and compressing/decompressing 1g plus files (these things save CPU resources so that my laptop is free for gaming while it's underway). I also have Xfree86, gtk, and qt installed for developmental purposes, although I only use them via VNC (there are only 3 wires plugged into this computer: a powe cable, an ethernet cable, and one USB cable for the printer.)

    One of these days I might install an encrypted proxy server so that I can use the net from any location without anybody being able to track what I am doing (in case I get a job at a place that does that, but I am not under those circumstances at the moment)

    With everything I have installed so far, only ~2 gigs has been used up, so the -O3 option doesn't waste that much space.

    Really the difference between -O2 and -O3 is not that big. But my harddrive is pretty slow and there is a big difference in loading time for some apps (openoffice especially).

    hmm nice to see an other gentoo vicitm,
    i've been trying to get my gentoo working proper (installed it 2 days ago from stage2)
    now kinda stuck @ xfree (it won't work proper, window dragging = freeze linux).

    Seems like a common problem for KT400 chipsets with 2.4.22 kernel ... =(
    (http://odin.prohosting.com/wedge01/g...adeon-faq.html)
    (AGPGART, agp aperture size isn't detected proper => error msg "agpgart: unable to determine aperture size") and updating to kernel 2.6.2 gave me new errors (devfs not installed or smth BUT aperture size is now detected corectly )

    some advise (from the expierence i got in these 2 days ):

    Don't use genkernel, the one on the latest cd has some bugs which prevent booting the kernel correctly (you could update your genkernel version to fix it, but use manual kernel config. it's not that hard)
    Don't forget to add your network card and usb devices (module or inbuild). and add it to your autoload.d .

    and yes, redhat and mandrake are really worse if you want to learn linux (you won't learn much at all)

    Hmm...well, if it helps, I am rather novice when it comes to anything unix, yet gentoo is by far the easiest linux distribution I have ever used. I used to have all kinds of troubles with redhat and mandrake.

    Debian is pretty easy too, once you get it. You can use knoppix to install it, which makes it just that much easier still

    http://www.freenet.org.nz/misc/knoppix-install.html

    After that you can just use apt-get to install/update stuff.

    Well, I just cant get this to work. Genkernel keeps failing to compile the kernel. It says it cant find some files or directories and Ive followed the installation guide precisely.
