Where's the examples?????

Hi all,
	I'm playing around with the Boost library, www.boost.org, at the moment 
and the question is in relation to it but the question also applies to 
other libraries I've played around with, where are the examples and doco 
kept?

	I can't seem to find the Boost example source code anywhere. I also 
can't find the doco that comes with Boost. Is there a default location 
that ebuilds should drop examples and doco when dealing with libraries 
such as Boost? Boost does not seem to have a USE flag that says "Install 
examples somewhere" so I'm at a bit of a loss as to where this stuff is?

	Any thoughts greatly appreciated,

		Andrew

I don't know about the examples, but the doc useflag installs 
documentation in /usr/share/doc/boost-<ver>

I changed to -march=k8 in the make.conf file, removed all packages from
kde-base to trigger a meta recompile, then re-installed kde-meta and
compiled everything else using emerge -Dav system and emerge -Dav world.
I still get the same error.

from dmesg
kded4[16907] trap invalid opcode ip:7fde193e74d7 sp:7fffa5120510 error:0
in libqtGui.so.4.7.4[7fde19226000+a74000]
kcminit_startup[16909] trap invalid opcode ip:7fde193e74d7
sp:7fffa5120610 error:0 in libqtGui.so.4.7.4[7fde19226000+a74000]
kcmserver[16911] trap invalid opcode ip:7fde193e74d7 sp:7fffa511ff70
error:0 in libqtGui.so.4.7.4[7fde19226000+a74000]

So it appears that the problem is in libQtGui.so.4.7.4
How do I know that I've recompiled this?  I suspect this is still a
hangover from the original compile settings.

$ qfile libQtGui.so.4.7.4
x11-libs/qt-gui (/usr/lib64/qt4/libQtGui.so.4.7.4)

Look at the date time that you built x11-libs/qt-gui (in your emerge.log, or 
use genlop) and compare with said file.

dracut and the init thingy

Howdy,

I been messing with this init thing again.  I installed dracut, Googled 
like a mad man and finally got something to work, I think.  Here is some 
info:

root <at> fireball / # dmesg | grep dracut
[    3.378296] dracut: Checking reiserfs: /dev/sda3
[    3.378644] dracut: issuing reiserfsck -a  /dev/sda3
[    3.391728] dracut: Reiserfs super block in block 16 on 0x803 of 
format 3.6 with standard journal
[    3.392314] dracut: Blocks (total/free): 4883760/2828326 by 4096 bytes
[    3.392636] dracut: Filesystem is clean
[    3.393060] dracut: Remounting /dev/sda3 with -o ro
[    3.481926] dracut: Mounted root filesystem /dev/sda3
[    3.572413] dracut: Switching root
root <at> fireball / #

In my grub.conf I have this:

title=Initramfs-test
root (hd0,0)
kernel /boot/bzImage-3.1.5-1 root=/dev/sda3 init=/sbin/init
initrd /initramfs-3.1.5-gentoo.img

That is also what I booted with.  So, is it set up right?  It scrolls so 
fast I can't really see what it is doing in real time.  I don't know and 
can't find a way to confirm it is working so figured I would post what I 
can find here.  It did boot tho.

By the way, my root partition is sda3.

Thanks.

Dale

Miss the compile output?  Hint:

The files match, last compiled in the morning, two days ago, which is
before I tried my most recent changes.  

Success - Recompilation of this file gets me a k desktop.

Is there a good way to force-recompile an entire system's code?  emerge
-Dav system and emerge -Dav world don't seem to go down far enough in
the hierarchy to recompile all dependencies.

Many thanks.

Xen vs Citrix XenServer

Hi all,

I'm looking into virtualizing my servers (all 3 of them), and am a 
little confused as to the differences between Xen and XenServer...

First - I want to use a bare metal hypervisor that supports the following:

1. Can be installed on a USB FLASH drive (I have some Dell Poweredge 
2970 servers with the internal USB slot for just this purpose), and

2. Fully supports both Windows Server 2008 (our Domain Controller), and 
Gentoo Linux (our mail and web servers).

By 'fully' above, I mean, I can install the guest tools/additions, so 
I'll be able to safely manage the VMs (shutdown in case of an extended 
power failure, snapshots, migrations, etc)

I can't seem to find an ebuild for the xenserver tools, and when looking 
found out about Xen (I had thought that it went away a long time ago)...

Anyway, looking for any pointers from anyone currently running either of 
the two...

Thanks,

Charles
