Yes i think you can use /etc/portage/env for something like this
for eg
if you want to enable it for amarok
create a file /etc/portage/env/media-sound/amarok
with the contents
CFLAGS="-march=core2 -O1 -g"
CXXFLAGS="${CFLAGS}"
FEATURES="splitdebug"
MAKEOPTS="-j3"

Hi.
I've turned on splitdebug feature (and -ggdb in CFLAGS) so debug
information are saved and I can debug anything that crashes. I went to

and I found that it was almost 2GB, which chromium + firefox adds up
1.5GB and python gets another 0.3. I would like to disable splitdebug

splitdebug from features, re-emerging them and then activating

I wonder if there's a way to active features to some specific
packages, just like USE flags.
There is. And it's a very powerful one even. First, remove -ggdb (I
use just -g though; if you don't need the extra info -ggdb gives, plain
-g will save you some space and time) from your CFLAGS and splitdebug
from your FEATURES in make.conf. Then, create a file:
/etc/portage/env/splitdebug.conf
with the following contents:
CFLAGS="${CFLAGS} -ggdb"
CXXFLAGS="${CXXFLAGS} -ggdb"
FEATURES="${FEATURES} splitdebug"
Now, in /etc/portage/package.env, you can "execute" splitdebug.conf for
the packages you want. My package.env for example looks like:
sys-libs/glibc splitdebug.conf
media-libs/mesa splitdebug.conf
kde-base/kdelibs splitdebug.conf
kde-base/kwin splitdebug.conf
The result is that, for example, when glibc is emerged, splitdebug.conf
is executed which adds -ggdb to CFLAGS and CXXFLAGS (do not forget
CXXFLAGS!) and splitdebug to FEATURES.
As you can guess, you can create arbitrary .conf files like this; it
isn't in any way specific to splitdebug.

The arguments sent to gcc tell it what kind of object gcc is supposed to create. If gcc cannot create the object you request because it's not the right "kind" of gcc, implies that, within the same gcc version, it is unable to reproduce object files.

Thanks to all who replied for your suggestions and info! After experimenting with various combinations of settings it seems to be working now. I think I was too aggressive with the number of parallel make jobs, the laptop just couldn't coordinate that many. I also stopped distccd on the laptop, in case it was picking up jobs unintentionally. Here's the results, a real-life test with ImageMagick 6.7.1.0. The machines were idle, files were already downloaded, and I don't use ccache, so it should be actual compile time comparison only: Normal emerge on laptop, no parallel jobs in MAKEOPTS, no distcc: merge time: 8 minutes and 27 seconds. With -j3 in MAKEOPTS, using distcc: merge time: 4 minutes and 40 seconds. Great! Of course, on the desktop it only takes 1 minutes 17 seconds, but an almost 50% reduction in emerge time on the laptop is still great to see.

Either make udev rules to create the devices in the correct order, or specify the cards order (index) in your alsa config, such as on my system: $ cat /proc/asound/card0/id Intel $ cat /proc/asound/card1/id NVidia First is my on-board sound, second is my HDMI.

[gentoo-user] SIP clients
Any preferred SIP softphone on Gentoo? I've used Ekiga on Windows and Ubuntu, and it's only moderately painful there, but it's very, very, very old on Gentoo. If there are no good options, I'll stick with the SIP client on my android phone, for now. (hardphone isn't an option) -- :wq

The default is to have everything muted so it is very common for folks to forget that little but important detail. Also, on one of my rigs, I had to unmute with both Kimix and alsamixer. Just a thought. I've done this myself. and don't forget to mute spdif optical raw and try without pulseaudio first. Dale :-) :-) Hi Dale and Volker, I tried it without pulseaudio first and, Dale, my card is unmuted. ;) Totem and vlc are working without any problems but ff and chromium aren't able to produce sound - and it is somehow related to the error message above. But Volker, I highly appreciate the tip with the spdif and I'll try that. Thank you very much. Kind regards, Max

My (totally biased and personal without any techincal background) advice is to stay clear of pulseaudio. Hi Leonardo, i tried it of course without pulse audio in advance, but e.g. totem and vlc were using the wrong "standard" device and emerging world with pulseaudio use flag makes totem and vlc use the right device ... my only problems are chromium and ff ... and probably some other apps, that I didn't test so far.

Hi again,
I found the problem (me). The correct syntax should be:
ATTR{dev}=="68:0", NAME="capi20"
ATTR{dev}=="191:[0-9]*", NAME="capi/capi%n"
Notice the '==' instead of '=' after ATTR{dev}.
Cheers,

That's unfortunate. The stop-service might be started to try to clean up when it fails. What kind of RAID are you using? Does it perhaps rely on a module that is loaded in the background? In which case you could try adding that module as a dependency? -- Joost

I just cleaned off KDE (and PulseAudio, as it happens) from my system Saturday night/sunday morning. I wasn't using the KDE profile. Here are the steps I followed: 1) Remove all 'kde' and 'qt' USE flags from make.conf. (I didn't have to remove qt, but I preferred to switch over to package-specific support for it, as needed, rather than global) 2) emerge --depclean (pretend first, then add anything I *knew* I didn't want to lose to @world, then pretend again, until there wasn't anything that would be removed I wasn't comfortable with) 3) If there were any KDE packages left, emerge -pPv on them, to find what was pulling them in. "emerge --deselect" the packages that were pulling the KDE packages in. (Sometimes, this would involve supplying an alternative. For example, I had to emerge Awesome before it would remove knotify.) 4) Jump back to step 2, unless I couldn't get a package to disappear with --depclean. 5) revdep-rebuild (in my case, only a Jack library was busted) 6) emerge --deep --newuse --keep-going world && emerge --sync && emerge --update --deep --newuse --keep-going world # This part, I left running overnight. It succeeded, to my surprise. I did have a couple recursive-dependency-like situations. For example, KDE has a policykit agent, which depends on polkit. The policykit agent wouldn't go away; emerge -pPv said polkit was pulling it in, and said that the agent was what was pulling polkit in. In those situations, I found I had to --unmerge a piece of the dependency loop in order for emerge to allow it to go away or get replaced. In the polkit case, I removed the KDE agent. I also had to remove a few packages I do occasionally use, because they were pulling in Qt or KDE. In particular, I --deselect'd calibre. I've still got qt libs on my system, though, because I use Luminance-HDR a *lot*. I found it surprisingly painless. Note, I went through most of these steps with X *NOT* running; I switched to a terminal and stopped kdm before really going past step 2. -- :wq

Look for KDE/GNOME packages in your world file grep kde /var/lib/portage/world grep gnome /var/lib/portage/world Remove anything you don't use emerge --depclean -a rinse and repeat -- Neil Bothwick WinErr 01B: Illegal error - You are not allowed to get this error.

There is no specific RAID-service-file, so it seems to be done by udev and the related target/service somehow. lvm.service says After=udev-settle.service so udev should detect all devices first, then lvm.service gets started. But somehow this doesn't work here, only after hitting that timeout one time. Stefan

Re: [gentoo-user] systemd
next box tested. Installed systemd on my main workstation now that I understood how to easily flip back to booting w/ openrc in case of problems. I heavily use LVM here and this gives me the following issues: I use lvm.service from the gentoo-wiki: http://en.gentoo-wiki.com/wiki/Systemd#LVM For sure I enabled it ... When I boot this machine it boots up to starting the LVM-devices and waits for some time then writes something like: welcome to emergency mode ... Start of /dev/VG...something failed (due to some dependencies) (for all the LVs) and lets me login or press Ctrl-D to continue. (I can't remember the exact words, don't know if they are logged somewhere) When I press Ctrl-D all the LVs are mounted(!) and it boots up fine to graphical login. hmm. It then tells me: # systemctl status lvm.service lvm.service - Linux Volume Manager Loaded: loaded (/etc/systemd/system/lvm.service) Active: active (exited) since Mon, 22 Aug 2011 09:55:36 +0200; 22min ago Process: 5568 ExecStop=/sbin/lvchange --sysinit -a ln $(/sbin/vgs -o vg_name --noheadings --nosuffix 2> /dev/null) (code=exited, status=3) Process: 5861 ExecStart=/sbin/vgchange --sysinit -a ly (code=exited, status=0/SUCCESS) Process: 5738 ExecStart=/sbin/vgscan --mknodes --ignorelockingfailure (code=exited, status=0/SUCCESS) Process: 5654 ExecStart=/sbin/pvscan --ignorelockingfailure (code=exited, status=0/SUCCESS) CGroup: name=systemd:/system/lvm.service Why does that ExecStop fail? Why is it called at boot anyway? I also tried another lvm.service from the russian gentoo-wiki, that servicefile just pulls in /etc/init.d/lvm, but that didn't help so I went back to the mentioned file. What I wonder: what changes between running into that timeout and my pressing Ctrl-D? Thanks for helpful comments, Stefan
