[gentoo-user] emerge -e system - output info/errors to log

[gentoo-user] emerge -e system - output info/errors to log

[Tanstaafl]

I must be missing something obvious...

When updating gcc, and thus emerging -e both system and world, where are
the info/warn/errors logged? I see a whole bunch of separate/individual
logs ion /var/log/portage/elog, but what I'm looking for is a single,
easily readable log of all of the result info/warn/errors for each package.

When emerging system, I saw some warnings when emerging openssl, but
they scrolled on by way too fast, and now I can't find them...

Oh - and  this is a server, so no X, so no elogviewer...

Hmmm, no GUI.  See if you can use this:

elogv

Which comes from here:

root@smoker ~ # equery belongs elogv
  * Searching for elogv ...
app-portage/elogv-0.7.4 (/usr/bin/elogv)
root@smoker ~ #

I use that in a console when my GUI is not working for some reason.  
Usually because nvidia needs to be recompiled because of a updated kernel.

It's not the prettiest thing but it should work.

Why are you doing that? Have you verified that you have in fact updated gcc 
from one version to another with an incompatible ABI?

There is a false idea floating about that gcc updates require updating -e 
world.

This is not true.

Configure it in /etc/make.conf, mine looks like so:

PORT_LOGDIR=/var/log/portage
PORTAGE_ELOG_CLASSES="warn error log qa"
PORTAGE_ELOG_SYSTEM="save"

Adapt to you own needs.

If you don't have this configured, then the logs are not stored. To see them 
again, read the ebuilds or re-run emrge

Because it wasn't a minor bugfix update? I'm going from 4.1.2 to 4.3.4.

Since the GCC upgrade guide doesn't mention a way to do this, no, I
haven't... so how does one verify this, Obi-Wan? ;)

I've heard this before, but could never get a definitive answer on how
to know for sure when you do and don't need to...

I have the last two, but didn't have the first - just added it...

So, does adding the first entry provide an overall emerge.log with just
all of the messages in it that I can review?

Like I said, I have a bunch of *individual* logs (for individual
ebuilds)... I was hoping for something a little easier to manage/read,
all in one file...

So what?

Is there an ABI change between 4.1.2 to 4.3.4 that causes apps built with 
4.1.2 to break on 4.3.4?

Understand what the gcc upgrade guide is:

a quick simple guide for user who don't know tool chains inside out, that give 
the minimal sequence of commands that is GUARANTEED to NOT leave the user in 
the lurch. It's not the minimum possible sequence of commands to do the 
upgrade, because most users don't know how to tell the difference. Here's the 
logic:

"If we imply that you should merge -e world with a gcc upgrade, my inbox will 
not fill with bugs from users who don't know the inner guts of the toolchain".

The Guide is not the best possible guide that can be. It is the guide that 
causes the least support questions from users.

When the gcc devs release a new version, they will announce that there is an 
ABI break, and what it applies to. It doesn't happen often, but when it does,
the gentoo maintainer ought to put a note in the ebuild.

They are quite diligent about this, much like the KDE/Qt devs do the same 
thing when Nokia breaks Qt compatibility.

I think that's the default. I have it just to be explicit.

for I in $(ls -1rt /path/to/emerge/logs/*) ; do cat ${I} >> some_log_file ; 
done

PORT_LOGDIR is where full logfiles are saved and predages ELOG*. If it is
not set, full logfiles are not saved at all. /var/log/portage/elog is the
default for elogs if PORT_LOGDIR isn't given.

This is the second time that someone has said something like this with
respect to the official Gentoo Guides (the other was the kernel upgrade
guide, and its recommendation to use ''make menuconfig instead of 'make
oldconfig')...

It would be nice if there were a formal/official place to find 'Advanced
User Guides'... ;)

I think that is where this mailing list comes in.  Here, you can say 
what you have, what you want in the end then someone can tell you a way 
to get there.  Usually, you will get more than one way and have to pick 
your poison.  I agree with what Alan said tho. The guides have to be a 
work every time for every one that reads it.

My preferred approach is to add mail to PORTAGE_ELOG_SYSTEM to get each
elog message mailed to me. That's still separate message, but I think
that's better as I can mark each one read as I've actioned it, leaving me
with a clear list of what's left to check or do.

Thanks for this Neil, I like this way much better than working with logs. :)
