I think it could be useful for new Gentoo users to have USE flag combinations that others use/know work. On a few early Gentoo installs I ran into trouble with the default USE flags ... which forced me to try other combinations to get the system up and running.
My last build (on an Acer Laptop) has the following make.conf file
Code:
# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /etc/make.conf.example for a more detailed example.
#next lines original file entries
#CFLAGS="-O2 -pipe"
#CXXFLAGS="-O2 -pipe"
#next line replacement for above
CFLAGS="-march=athlon64 -O2 -pipe"
CXXFLAGS="${CFLAGS}"
#next line added to optimise for dual processors
MAKEOPTS="-j3"
# WARNING: Changing your CHOST is not something that should be done lightly.
# Please consult Gentoo Linux Documentation -- Changing the CHOST variable before changing.
CHOST="x86_64-pc-linux-gnu"
# These are the USE flags that were used in addition to what is provided by the
# profile used for building.

source /usr/local/portage/layman/make.conf
It should be noted that I run the "Funtoo" variant (Daniel Robbins portage tree) and I usually make my own make.conf by hand, and not even use the one provided by the build scripts.
Thanks for sharing gruven ... thats quite a USE flag string ...
Funtoo but I think I'd better stick with stable ...
Yeah, my use flags are backed up with every install I have ever had, and I am sure there are some that aren't needed anymore, but it hasn't caused any problems. I like to customize my builds as I see fit, and I have some in /etc/portage/package.use/files.
I also like to specify different directories for my distfiles, packages, etc... because I can switch between funtoo and portage easily as my mind sees fit (not just switch branches, but remove /usr/portage and download a new tarball and not lose anything.
I have been using Gentoo for quite a few years now, and I can handle the instability in funtoo, although it is actually quite stable.
I use Gentoo also and my USE flags look quiet like those gruven uses with the exception of one two plus/minus flags. gruven, I like how you have split the use flags Alphabetically, it keeps everything nice and pretty. I think I'm going to use your idea because it makes sense too. Anything I should be aware of by using this method?

Just make sure you comment out anything you don't plan on using as a use flag, and keep everything in the parenthesis like so: USE="everything goes here no matter what".
Hi MikeTbob - any chance of posting the magic combination that works for you? ... maybe I've gone mad but I'm sure the original post had use as one long string ... I would have commented on the seperation as well if I had seen it ... the custom portage tree had not really crossed my mind - I probably would run separate root partitions and share user data . Maybe I'll get a bit more creative with the config when I'm more familiar with Gentoo ...

They weren't seperated before, I edited it to do that.
I usually keep the normal portage tree, layman trees, a funtoo tree, and my own local overlay, but this time I left out the regular portage tree and just went with the funtoo tree because it is being updated daily and I like the changes Daniel is making.

Hiya Jonathan, my use flags are on just one line as you mentioned but I edited it here so it wouldn't mess up the forum borders and width.
Code:
CFLAGS="-O2 -march=i686 -pipe"
CXXFLAGS="${CFLAGS}"
# This should not be changed unless you know exactly what you are doing. You
# should probably be using a different stage, instead.
CHOST="i686-pc-linux-gnu"

I just realized I use wayyyyy to many use flags and I haven't changed my CFLAGS or MAKEOPTS since before I purchased a new MOBO, which is a
Code:
cpu:0
description: CPU
product: Pentium(R) Dual-Core CPU E5200 @ 2.50GHz
vendor: Intel Corp.
physical id: 4
bus info: cpu@0
version: 6.7.6
serial: 0001-0676-0000-0000-0000-0000
slot: CPU 1
size: 2500MHz
capacity: 2500MHz
width: 64 bits
clock: 200MHz
. So MAKEOPTS="-j3" is better for dual CPU's?

MAKEOPTS
With MAKEOPTS you define how many parallel compilations should occur when you install a package. A good choice is the number of CPUs in your system plus one, but this guideline isn't always perfect.
Thats why I set -j3 for my dualcore setup. But I guess its a guide. Gruven has quite different values ... I was going to ask but thought I'd do a bit more reading first
I'm sure last time I looked at USE flag list it was a bit shorted than this ... but I also remember reading somewhere about causing problems having too many USE flags. Which is why I was a bit suprised by the long string.
As you know Gentoo is not my main distro (so absolute optimisation is not my aim) ... I ran into trouble because the default flags didn't really work for me. I thought having some more combinations of things that work might help others (and me next time I get in trouble). Having said that I'm picking up some great tips along the way
