Experiment: using -O3 in the toolchain

Ken Moffat — 2012-05-24T02:34:21

 Last month, I was querying the use of -O3 in glibc with x86_64 on
lfs-dev : turned out my problems on that one machine are down to
buying cheap consumer-grade hardware (it works, mostly) :)  But I
then got to thinking about using -O3 for the rest of the toolchain.
I've now completed test builds (CFLAGS and CXXFLAGS = -O2 everywhere,
and with -O3 in chapter 5 pass 2 and chapter 6 binutils, gmp, mpc,
mpfr,gcc).  Note that some packages, particularly in BLFS, ignore
CFLAGS.  The toolchain testsuite results are no different (same
failures in gcc, and with static libs which I do not install).

 This is x86_64 on an i3 (hyperthreaded dual processor, the kernel
thinks it is 4 processors) with 4GB of RAM.  I built these in
directories because they aren't intended to be used, and I didn't
build the kernel (that would be another 4 or 5 minutes!).

 Apart from that, I built everything that is currently part of my
normal desktop, and using -j3 for builds (but not installs!) except
where that gives problems.  I try to r

console graphics libraries (was Re: libre kernel)

LM — 2012-05-22T11:37:31

I've had mixed luck with svgalib.  It worked fine on an old Sony
laptop, but my main desktop with ATI All-In-Wonder (PCI-Express) card
just can't seem to work with it.  I tried several settings changes
with svgalib and just couldn't find a way to use it on that system.  I
have been looking into using directfb with various libraries in order
to get progarms to work outside of X.  That solution works for my
desktop, but unfortunately, probably won't work for the laptop which
has an older video card (neomagic).  SDL works with directfb.
WxWidgets is working on a directfb port.  I also found an older
version of fltk that's meant to be used with directfb.  Pdcurses also
works with SDL and directfb, although ncurses works fine directly in
console mode.  Keep thinking that with the right libraries one could
make a pretty nice distribution that doesn't need to use X, but could
still be used for basic desktop functionality like word processing,
audio and basic graphics and video editing/viewing.  If anyone runs

 Please excuse the test message. I was receiving other messages but not 
my own I think due to to an error in my Muttrc file and also testing a

libre kernel

Mike Hollis — 2012-05-18T15:51:39

 I just subcribed to this list and as yet have recieved no mailings to 
reply to, but this is relevent to the earlier posts about the gnu 
gnu-linux discussion. As the one poster said this will probably never
be resolved and I don't wish to open that can of worms.
 The discussion did get me curious and I checked the gnu web page as I
hadn't looked at it in some time and it pretty surprising to look at the
listed "free distributions". None of what I considered to be the major
players in early linux development were listed for various reasons. They
also offered scripts to remove the "blobs" from the vanilla linux 
kernel.
 I took a quick look at one of the "de-blob" scripts and was surprised 
at how extensive it was. My question is to anyone that has experience or
expertise in this area: Would these kernels lose considerable 
functionality compared to a regular kernel ?


Thanks,

Why not GNU/Linux From Scratch

LM — 2012-05-09T11:00:34

Just my two cents, but what happens when you use utilities from the
BSD toolchain on your system as well (like libarchive).  Does it
become GNU/BSD/Linux From Scratch?  What if you have pieces with other
licensing arrangements (zlib, etc.) or you're using llvm or some other
compiler in place of GNU gcc?  Do you change the name again?  Linux
from Scratch is a pretty well-known name and it pretty much sums up
what it is, a way to build Linux from Scratch.

Why not GNU/Linux From Scratch

Armin K. — 2012-05-08T10:10:32

Today I got an interesting question on LFS IRC:

<stallman mode="on">
Why LFS is called LFS and not GLFS (GNU/Linux From Scratch)
</stallman>

What do you think?

ncurses versus pdcurses

LM — 2012-05-07T11:19:57

Was just wondering if anyone could think of any pros or cons to using
pdcurses in place of ncurses for certain curses based applications.  You
can build pdcurses to work with X11 and run the applications directly
within X or you can build it using SDL which can add framebuffer support
with directfb.  Most of the applications I'm looking at that use curses are
cross-platform applications, so they're designed to work with either
library.  Would be interested in hearing opinions.  Thanks.

Ghost in the machine ? : .la file(s) getting emptied

Ken Moffat — 2012-05-04T12:30:26

 I'm just trying to upgrade a package on my LFS-7.1 system, and a
compile failed because /usr/lib64/libstdc++.la was not a valid
libtool archive.  Too right - it was empty!  Looking at ls -l it was
updated on 30th April (original install was on 8th April).

 Fortunately, my oldest backup was before that and I was able to
restore it.  But I'm sure I've seen something similar, perhaps even
the same file, in the past few months (not necessarily on this
particular system).  Looking at other updates, nothing (apart from
kernel upgrades) since 28th April until today.

 Anyone seen anything like this ?

The hobby of bootable media

Andrew Elian — 2012-04-23T23:23:35

Hello one and all,

I've been puttering away with LFS 7.1 and turning it into a bootable
DVD.  The end result does boot and work in qemu.  Perhaps there is an
adventurous soul would like to try it out.  I wouldn't mind some
feedback on it.

Thanks!

experience with PowerPC

epersistente — 2012-04-11T01:56:00

Hi,
Someone has been able to build LFS in a PowerPC machine? (Applied
Micro APM82181)

Thanks

Has someone tried LSF on WesternDigital myBookLive?

epersistente — 2012-04-10T16:33:16

Hi,

I got as a gift a WD 2Tb myBookLive blue light and I wonder in any of
you have tried to build LFS on this little NAS drive.

If so could you please talk a little bit about your experience?

The myBookLive disk is a PowerPC Debian Network Attached Storage drive.

Thanks in advance

Linux Tycoon: a game where you build your own distro

Aleksandar Kuktin — 2012-04-03T21:43:32

Just dropped by Linux Game Database (http://www.lgdb.org/) and..
well, they added a new game to the database.

Copy-paste:
Linux Tycoon is the premier Linux Distro Building Simulator game in the
universe.

So what exactly do you do in a Linux Distro Building game?

So glad you asked! Here’s some examples of the thrilling challenges
you’ll find in Linux Tycoon:

Analyzing and selecting software packages.
Fixing Bugs.
Managing volunteers and paid staff.
Keeping the total size (in MB) of your Distro at a reasonable level.
And so much more!

Seriously though. It is fun. (It is a game, after all. You don’t
actually fix bugs yourself.)



LMAO. I just have to post a link to it here. :)

Changes at glibc

Andrew Benton — 2012-03-28T09:39:21

Hello,
It seems that the glibc steering committee has disbanded
http://sourceware.org/ml/libc-alpha/2012-03/msg01038.html
"the direct responsibilities of GNU Project maintainership for the C
Library will be taken on by a smaller team led by Joseph Myers, Carlos
O'Donell, and Roland McGrath", a group that does not include Ulrich
Drepper.
Glibc has certainly seen more changes lately. I wonder whether this
recent volatility is just a passing phase that will settle down, or
will it continue for years?

in soviet russia, LFS builds you

Ken Moffat — 2012-03-07T22:18:00

 Sorry for the OT (and totally inaccurate) title, but LFS-7.1 is on
slashdot.  Hope the server holds out, and hope those on -support can
handle any extra influx.

New arrival

Matt Burgess — 2012-02-29T19:32:27

Hi all,

Just thought I'd let you know that the Burgess household has a new
arrival as of approximately 2012-02-27 11:22:00 GMT when Alixandra Lilly
Burgess entered the world.  Mother and baby are both doing really well,
and were able to come home just 29 hours after an unexpected C-section.

Regards,

Matt.

Introducing myself

Rodrigo Marcondes — 2012-02-10T05:14:27

Hello Fellas,

My name is Rodrigo, and I'm a Computer Science student on Brazil.
I'm starting the Linux From Scratch 7.0, and liking the way things are
going.
I'm still preparing the enviroment for developing, and reading about most
of the stuff on Linux that I have to compreend to make a better use of the
book. I have experience with Ubuntu mostly, but I want to try an distro
much less expensive in the means of processing, I'm going to try using it
on a 1.7GHZ notebook, a realy limited one. So any suggestions would be of
trully inspiration.
I've made subscription also to the group e-mail of LFS Support yesterday.
Any group you guys would suggest to follow on with, so that I can learn
stuff of my knowledge level and possibly help others?

Thanks a lot fellas, I'm realy up to learn and make friends.

lfs -> Ubuntu cross compiler w/ apt?

Nathan Coulson — 2012-02-06T11:08:34

I built myself a compiler that can compile binaries for ubuntu (using
their libraries).  Originally I just used the standard LFS compiler,
but later on had a few messages that I believe were complaining that
my glibc was newer then ubuntu's.  (was long ago,  don't quite recall
the exact message).

To work around this, I built a

First, I grabbed a few of the ubuntu .deb files, and converted them w/
the deb2tgz utility.

Gordon Findlay — 2012-02-04T04:44:16

I have just completed LFS built from the v7.0 book, with OpenSuse 11.3 host.

It has been an interesting journey, with many, many errors.

But in every case - EVERY case - the error has been mine. Working through
the book is a fantastic test of attention to detail.

I write  instructional material in IT for  a living, and I know how
difficult it is to get details right. Congratulations on a job very well
done.

I'm away for a few weeks, then I'll try BLFS. . Just for fun :-)

Starter distribution

Adrian Fisher — 2012-01-14T13:23:10

Hello all,

I bought a new laptop in November (HP Pavilion dv6-6002sa Entertainment 
Notebook) and wish to start working on LFS 7.0 on it (replacing the 
existing OS with Linux).  What distribution is most recommended to use 
as a base?  I plan to start off with replacing Windows with a general 
distribution but to put Windows back on in a virtual machine through 
Virtual Box for work purposes.  I wish to create my new distribution as 
another virtual machine which I plan to use to replace the host OS when 
it is ready and I know more about what I'm doing.

Any suggestions?

Thanks in advance.
