[solved/complete] Fresh stage1 install, flags advice needed

[sedorox]

I'm just wondering... why does everyone here have such a long compile time for OpenOffice?

Code: Select all

Nereus ~ # genlop -t openoffice
 * app-office/openoffice

     Fri Oct 19 00:18:12 2007 >>> app-office/openoffice-2.3.0
       merge time: 3 hours, 18 minutes and 30 seconds.

You guys are really making me want to install gentoo on my desktop again (see specs in signature).

What can I say? It's addictive.

Hehe, you call that long? On my Turion X2 (1.6GHz per core) it took about twice as much (about 6 hours merge time). To say the truth I would prefer to have the times you're having. But everything will be fixed in the right time ( -> getting a new notebook somewhere in January, it'll be a Core 2 Duo, so I'll probably need to discuss the flags for it again).

This is on my 1.6Ghz Sempron Single Core... and I'm about to start my voyage of installing Gentoo on a HP Visualize Workstation C3000 (400Mhz PA-Risc). I guess I should prepare for some crazy long compile times

I wasn't calling my times long, I was saying everyone else's seems to be. Now granted I run a Core2Duo (E6550 @ 2.33ghz) with (at the time of that compile) 2GB Ram, but I would still think a dual core Turion would do better then that. I don't think I was using DistCC at the time either, altho I might have (which would have added a AMD64 3200+ with a gig of ram).

At least things aren't as bad as when I installed Gentoo on my PC back a few years ago, which was a AMD i586, running at 500mhz, and I think 384 megs ram. OpenOffice took DAYS.

Anyway, back on topic.. here is what I'm using with my c2d:

Code: Select all

 
Portage 2.1.4_rc9 (default-linux/amd64/2007.0, gcc-4.2.2, glibc-2.7-r0, 2.6.23-1 x86_64)

CCache isn't currently enabled as I had some issues I thought were related to it, but weren't, and I just never enabled it again.
I'm sure some of either the cflags or use flags are redundant, but never bothered to look up which.

Specs:
Intel Core2Duo E6550 2.33ghz
4GB DDR2 800
XFX Nvidia 7900GS
WD 250Gb SATA II
Intel 1000/PT PCI-Express NIC
Gigabyte Motherboard (P35 chipset)

Seems nice, but I won't be using AMD64, only x86. It works nice when optimized for my Turion, so I'll be doing the same for that C2D I'll be getting in two weeks from now.
These are the specs:

Code: Select all

Intel Mobile Core 2 Duo T7500 2x2.2GHz
4GB RAM SO-DIMM2 @667MHz
nVidia GeForce 8600GT 512MB RAM DDR3
Seagate 160GB, 7200RPM, SATA 300

Further flag advisory is welcomed.

EDIT: Ok, I think I got it ready.

Code: Select all

CFLAGS="-march=prescott -O2 -pipe -mmmx -msse -msse2 -msse3 -mfpmath=sse -fforce-addr -fomit-frame-pointer"
FEATURES="parallel-fetch ccache <and other eventually>"
MAKEOPTS="j3"

Still need to set the LDFLAGS for C2D. Standard settings perhaps?

[dnadesign]

Ok, got it up and running with the desktop profile and following settings:

Code: Select all

CFLAGS="-O2 -pipe -march=nocona -mfpmath=sse -mmmx -msse -msse2 -msse3"
CFLAGS="${CFLAGS} -fforce-addr -fomit-frame-pointer"
CXXFLAGS="${CFLAGS} -D_FILE_OFFSET_BITS=64"
LDFLAGS="-Wl,-O1 -Wl,--hash-style=gnu"

CHOST="x86_64-pc-linux-gnu"
FEATURES="parallel-fetch ccache"

MAKEOPTS="-j3"

USE="-arts gtk gtkhtml gnome hal dbus threads bash-completion samba mono java php apache2 mysql"

VIDEO_CARDS="nvidia"
ALSA_CARDS="hda-intel"
LINGUAS="pl en"

In the end I finally decided to go on AMD64 (no memory limit problems... God, am I lazy or what... ). Works like a charm.

Thanks for all your help everyone.

EDIT: OpenOffice 2.3.1 compile time: a little bit more than 2:30 hours (I wasn't in the room, when he finished, came in a bit later)!!!!

Out of curiosity, what does --hash-style=gnu gain you? And I guess there is a big difference between the 6550 and the 7700, or if your using the faster memory then I, as you're about 45 mins ahead of me on compiling OpenOffice.

Well... I just kinda got used to having it in my LDFLAGS, as far as I remember it had something to do with a new hash symbol table for the ELF binary format. As I said: I just have an old habit of using it.

As for the compilation time differences: my memory chips are working at 667MHz, on a 800MHz FSB. If it's not that, then maybe CCACHE had something to do with it. I never experienced such a fast compile time for OO, but I also used CCACHE for the first time.
