 Posted: Sun Aug 03, 2008 9:09 pm Post subject: What is emerge -e system? |
 |
|
Hi, I just have a general question. Lately I was thinking of changing my cflags to include -march=core2. Although for some reason, even tho I have a core2 processor, after setting my cflags to core2 or auto, emerge fails. However, thats another question for another time. What I wanted to know, was that i found that even with -march=nocono, emerge -e system has a ton of updates. What exactly does emerge -e do? and whats the -e flag stand for?
Also running emerge -e system broke xorg until ran emerge nvidia-drivers. Why is this the case? emerge -uDN world doesn't have anything else run? Whats going on with my system here? I'm just curious about wats going on behind the scenes in gentoo. Thanks guys  |

--emptytree (-e)
Reinstalls all world packages and their dependencies to the current USE
specifications while differing from the installed set of packages as
little as possible. You should run with --pretend first to make sure
the result is what you expect
In other words, reinstalls your entire world file. Use emerge -euDNav world system to reinstall almost everything (use eix -cu to find what else - unlikely to be much, tho)

its worth remembering that in recent versions of portage (i dont remember the exact version that this changed) system is no longer part of world, so for a complete rebuild you need to call them both.

You're speaking about the forthcoming portage-2.2 of which there are already several release candidates out in the wild

So up until now, when I run "emerge -DNua world" I would have been ok? (I haven't got 2.2 yet).
So from 2.2, what is considered "system"? Are there any descriptions on that somewhere (a blog entry or whetever)?
Lastly, the -e flag then. Am I right in thinking that adding -e to my usual set of flags (-DNua) will make emerge also re-install things that hasn't changed in terms of new versions or changed useflags?
Not to hijack BurningIce's thread, I am guessing that the installation of xorg have a default config, that gets updated when you install the nvidia drivers. Your old config might have been saved in a backupfile in /etc/X11.

geez - I've been on 2.2 as well... system is (AFAIK) everything in the old system... stuff like python, gcc, libc, you know... system stuff. World is everything in your world file. | Quote: |

|
true - only use it occasionally, like when you need to rebuild everything. (I like to think of the "e" as "everything" instead of "emptytree")

well, a simple | Code: | | # emerge -pv system |
lists the packages of system. |

Also if you want the old --emptytree action without useing -euDN then | Quote: | man emege
--with-bdeps < y | n >
In dependency calculations, pull in build time dependencies that
are not strictly required. This defaults to 'n' for installation
actions, meaning they will not be installed, and 'y' for the
--depclean action, meaning they will not be removed. This set-
ting can be added to EMERGE_DEFAULT_OPTS (see make.conf(5)) and
later overridden via the command line. |
In other words add EMERGE_DEFAULT_OPTS="--with-bdeps y blah blah" to your /etc/make.conf. Then --emptytree will rebuild everything in either system or world.
System used to be the eqvilent of a stage3 and world was everything including system packages. Now a "emptytree system" on my box includes Xorg and parts of gnome for a basic X system. World includes xfce4, firefox, mplayer, ....
You can look and play with things with this | Code: | emerge system -ep>sys.lst
emerge world -ep >wrld.lst |
NOW the follwing gives and list of just packages, sorted, which allows you to use "comm" to compare them.
| Code: | grep ebuild wrld.lst |cut -c17-64|sed 's/\[[0-9].*//'|sort >sw.lst
grep ebuild sys.lst |cut -c17-64|sed 's/\[[0-9].*//'|sort >ss.lst
comm -3 ss.lst sw.lst | wc
232 233 6842 |
See "man comm" and "man wc". these are 2 simple tools, comm compares to sorted files and wc counts how many lines such.
If you dont pipe the comm output thru "wc" it gives the file listing instead.

Well portage-2.2-rc6 has diffently changed because I have the exact same problem.
| Code: | hielvc@localhost ~ $ emerge system -uDNqp
hielvc@localhost ~ $ emerge world -uDNqp
[ebuild U ] app-portage/eix-0.13.3 [0.13.2]
hielvc@localhost ~ $ emerge -uDNqp terminal
[ebuild U ] xfce-base/xfce-mcs-plugins-4.4.2-r1 [4.4.2]
[ebuild U ] dev-python/pycairo-1.4.12 [1.4.0]
[ebuild U ] dev-python/pygtk-2.12.1-r2 [2.12.0]
[ebuild U ] x11-libs/vte-0.16.14 [0.16.10]
[ebuild U ] xfce-extra/exo-0.3.4 [0.3.2]
[ebuild U ] x11-terms/terminal-0.2.8 [0.2.6_p25931] |
This not how "emerge " is supposed to work.

If it can be interesting for you, I have similar results with my x86 stable profile, portage 2.1.4.4.
| Code: | $ emerge -ep world | grep "\[ebuild U \]"
[ebuild U ] app-arch/lzma-utils-4.32.6 [4.32.5] USE="-nocxx%"
[ebuild U ] sys-apps/ed-0.9 [0.8] |
ed gives the same result as BurningIce, and the other package displays as follows:
| Code: | $ equery d lzma-utils
[ Searching for packages depending on lzma-utils... ]
media-libs/libpng-1.2.26-r1 (app-arch/lzma-utils)
sys-apps/coreutils-6.10-r2 (app-arch/lzma-utils)
sys-devel/m4-1.4.11 (app-arch/lzma-utils) |
Then I have this other thing (I run Xfce):
| Code: | $ emerge -ep world | grep "\[ebuild N"
[ebuild N ] dev-util/xfce4-dev-tools-4.4.0 |
but I emerged -1 it and now:
| Code: | # equery d xfce4-dev-tools
[ Searching for packages depending on xfce4-dev-tools... ]
# |
Nothing. So I now emerged -C it.
My current emerge --depclean -p does not pretend to delete anything.
The emerge -uDNpq --with-bdeps=y @world command returns me an error, probably due to my old portage.
If this post is useless, please delete it.

For some of the problem, if not all is on me. Frist Arfrever " emerge -uDNpq --with-bdeps=y @world " showed the same, just eix. It should I have EMERGE_DEFAULT_OPTS="--with-bdeps y --buildpkg" in /etc/make.conf. But | Code: | | emerge -p --depclean |
gave a list of 77 packages. I think what happened was I ran "dep -w" from udept, and it said "gee I can really your world file". Well I meant to enter "n" but hit "y" and didnt stop it in time. I run xfce4 and 10 or more of the cleanning list are xfce4 files. Guess which is one of the entrys in /var/lib/portage/world thats missing

Must say I am not that big a fan of 'e's any more...
Tried this a few days ago
| Code: | | emerge -DNuea world |
It came up with 788 packages. My poor AMD 2500+ (I have lowered the speed from 3200+ for stability), it did about 500 packages before it started getting lots of segmentation faults in the compiler. I think the poor thing overheated. Tried --resume, but it didn't last more then 1 or 2 packages before it came again.
I gave up the whole thing and just run a revdep-rebuild to fix things. After a couple of nights rest I have run "emerge -DNea compiz-fusion". This pulled in 404 packages and is now almost finished without segmentation faults this time.
Es might be fine, but I guess its best not to use too many of them (they can be damaging to your health)

it really seems you have a cooling problem, monsm.
you should really do something against that, or your hardware will die. seriously, change that! |

Thanks, yes, suspect you're right. I'll have to open the box and check for dust and see if all the fans are ok. Maybe get a better CPU fan.
And possibly install a sensor application to keep an eye on it.

most modern mainboard have a bios that can display senor values.
sys-apps/lm_sensors is the application that reads sensors under linux.
app-admin/gkrellm and app-admin/conky are nice graphical frontends you can use. |

Think I have sorted my problem now. Got the sensors running, but the temperature wasn't actually that bad. I installed and run memtest86+ and it showed up lots of errors. I remember I messed with the timings and slowed the cpu down (from original Athlon 3200+ to 2500+) some time ago to get rid of some other memory errors. Now it was back again.
Vacuumed a bit, moved the memory modules a bit. Then I reset the bios setting to the defaults, but moved the CL setting from 2.5 to 3. Turned out I had 2 different brand of modules, 2 of them was rated to 2.5 and the last to 3. So using 3 seemed to work.
So ironically I run the machine faster now, and have less problems
