Cannot reinstall ffmpeg since new cpu flags

Hi,

I have installed the new CPU_FLAGS_X86, as "cpuinfo2cpuflags-x86"
told me: CPU_FLAGS_X86="mmx mmxext sse sse2 sse3"

When I did "emerge -NDuv  <at> world" afterwards, there were some re-installs.
Everything was fine, except ffmpeg. emerge displays:

[ebuild   R    ] media-video/ffmpeg-1.2.6-r1  USE="bzip2 encode examples fontconfig gnutls
hardcoded-tables iconv libcaca mp3 network truetype vorbis x264 xvid zlib -X -aac -aacplus -alsa (-altivec)

and running emerge, after many lines, I
get

USE-flags description?

Hi Gentoo-users,

where can I find description of *all* USE flags? I checked
/usr/portage/profiles/use.desc and use.local.desc but still
I can not find some...

cpuinfo2cpuflags-x86 suggested my CPU_FLAGS_X86 should be:
"aes avx mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3"

But I'd like to know what they means, but I could not find
any description for "aes" and "popcnt"...

Jarry

Smart 'eclean packages'?

Do we have an eclean option that will consider how long ago a package
was uninstalled?  Last I checked this didn't exist yet.

[OT] ASUS Crosshair V Formula-Z MB

I just got me a new MB, a ASUS Crosshair V Formula-Z, after my old MB
fried due to a fan failure.

Is anyone else (on this list) using this MB, with Gentoo of cause?
If you are, have you got all the sensors working?
I can not get information from all the sensors on this MB (compared with
what the BIOS shows) and some of the values that do show are wrong ,
some temp-sensor shows as negative (and my room is not THAT cold).

Regards,

IPAM: phpipam ?


What do you gentoo-users prefer for doing IPAM ... ?

Learned about http://phpipam.net today ... no gentoo ebuild yet.

opinions? recommendations?

meld - GConf Error: Client failed to connect to the D-BUS

When I run "meld" as root I get a strange errors:

GConf Error: Client failed to connect to the D-BUS daemon:
Did not receive a reply. Possible causes include: the remote application did not send a reply, the message
bus security policy blocked the reply, the 
reply timeout expired, or the network connection was broken.

KernelShark is almost ready?

So, I've been looking to get kernel shark onto gentoo,
for a long time....[1] Look at this link to wet your
appetite!

KernelShark(gui) is a very, very functional way to look at just about
every aspect of kernel performance. It needs trace-cmd to run.
Guess what just made it into the portage tree? 
(dev-util/trace-cmd) THANKS to  Patrick McLean <chutzpah <at> gentoo.org>!

You'll have to make some adjustments to your kernel settings (maybe)
to activate ftrace.

I wrote extensively about KernelShark/trace-cmd/ftrace in this bug, 
which is still looking for a gentoo dev to complete (please?).
BGO 517428.

Now to wet those appetites, look here [2,3] at section 3.7 and 3.8.
It seems our 'pals' at RedHat offer there most optimized servers
that are extremely tweaked in the kernel (real-time) by using these
tools; particularly for their cluster offerings that cost big_bucks.

android development with Qt in a Gentoo box

Hi,

I am new to android development. I know a bit of C++ and Qt, but almost nothing about Java.

Which would be the needed packages, besides the ones listed on http://wiki.gentoo.org/wiki/Android 

Any hints, please?

Thanks!

netifrc & system init actions

  Hi all.

I need to have some ip policy rules at system startup which isn't depend on
any interface. In debian i do this through /etc/network/interfaces - i add
needed rules as post-up actions to lo interface.

In gentoo i've made postup() in /etc/conf.d/net:

postup()
{
        if [ "${IFACE}" = "lo" ]; then
                ip rule add priority 32000 table main
                ip rule add priority 32001 from 77.247.233.224/30 lookup vsd_linknet
                ip rule add priority 32050 from all lookup customers
                ip rule add priority 32100 table peering
                ip rule add priority 32101 iif eth0 lookup up1
                ip rule add priority 32101 iif eth0 lookup default
                ip rule add priority 32200 table ix
                ip rule del priority 32766
        fi
        return 0;
}

and done:

rc-update add net.lo default

Is this the right way to do this?
