stage3 for Haswell, built with gcc-4.8.1 and -march=native

Message

Disclaimer: I work for Intel. This is my own personal project.

Lots of people are upgrading to Haswell (including myself). Stable gcc-4.6 doesn't support -march=corei7-avx2 and frequently fails to compile packages with -march=native on Haswell.

I thought I'd save myself time and some trouble by building a stage3 with gcc-4.8.1 (and while I'm at it, with -march=native on a Haswell).

I hope it saves you some time too.

Cool!

I just built an i7-4770 based desktop and last night I installed Gentoo using the standard instructions (modified for UEFI). I didn't see this post until today.

I saw that I might run into some issues with the stable version of gcc, so I switched to ~amd64 from the very beginning, and upgraded gcc to 4.7 as soon as I could. That let me use -march=native to compile the rest without errors, but I would love to switch up to gcc 4.8.1, and re-emerge everything.

I used to use Gentoo many years ago, but at some point I switched to Debian stable, so my Gentoo knowledge is pretty rusty. I apologize in advance if these are silly questions:

Is your stage3 built from ~amd64? (Will it result in a ~amd64 system?)
Without starting over from scratch, what is the easiest way for me to get my system to the same state that starting from your stage3 would give me?
Am I using an old mirror, or did you have to do something special to get gcc 4.8.1?

I plan on using ~amd64, and I just finished going through the base install, so I haven't installed much of anything else yet, as I would like to get my gcc up to 4.8.1 and rebuild everything first.

It's stable amd64, but with and built by an unstable (and masked) gcc-4.8.1.

Unmask and install gcc-4.8.1 (see below) and then

Code: Select all

emerge -e @world

Yes, gcc-4.8 is currently hard masked. You can unmask it and install with

Code: Select all

mkdir -p /etc/portage/package.keywords /etc/portage/package.unmask
echo "=sys-devel/gcc-4.8.1 **" >> /etc/portage/package.keywords/gcc-4.8
echo "=sys-devel/gcc-4.8.1" >> /etc/portage/package.unmask/gcc-4.8
emerge =sys-libs/gcc-4.8.1

Oh, that is very nice! If I ever need to set up a stable install, it sounds like your stage3 is the way to go.

Thanks! I just finished emerging gcc-4.8.1 using your instructions. Wow, this is one fast machine!

very nice, thanks a lot !
i will have a Haswell based laptop in short and this will save me some time.

I'm using gcc-4.8.1 with the suggested use flags - but I always get a glibc segfault sooner or later during

and then emerge doesn't work any more:

Code: Select all

# emerge --resume

 * IMPORTANT: 4 news items need reading for repository 'gentoo'.
 * Use eselect news to read news items.

Calculating dependencies \Segmentation fault

After countless tries to

Code: Select all

# emerge --resume

I can get some more packages built.

I've unmasked bintutils-9999 out of ideas

Code: Select all

=sys-devel/binutils-9999 **

but to no avail. The system itself is very unstable, Thunderbird, Firefox, Netbeans constantly crash (but do work for some time).

Any ideas?

What I don't understand is why it often fails while installing a package, e.g.:

Code: Select all

in case you are bullding with -O3 then thats the problem.
ive been using 4.8.1 on my lappy for 3 weeks now and not a single build issue so far.

cheers

I'm using the default Safe CFLAGS:

Code: Select all

CFLAGS="-march=native -O2 -pipe"

What are you using?

gringo · Post by **gringo** » Thu Aug 29, 2013 4:54 pm

same as you : CFLAGS="-march=native -O2 -pipe" and all packages have been built with 4.8.1.
i did not use this stage IIRC, just because i forgot about it.

mine is a 4900MQ.

cheers

I installed gentoo on my newly built Haswell PC (i7-4470) using the above stage3, which really helped a lot, so thanks to the OP.

I'm using CFLAGS="-march=native -O2 -pipe", no problem in 3 weeks of gentooing.
I'm using default desktop profile with xfce4, firefox. Didn't run in any build problems during installation at all.
gcc 4.8.1 was recompiled during an emerge -uNDpv world early on however, didn't check exactly why, maybe change in use flags.

Is this stage still the better one to use? I will be doing a gentoo install on my 4770K in the next couple of weeks and just want to know if this is still applicable
