[gentoo-dev] emerge --pretend update questions.

[gentoo-dev] emerge --pretend update questions.

[jasonm]

hi,

hopefully this will be my one and only stupid question on this list. :)

i'm trying for a better understanding of the output from:
$emerge --pretend update

when executed on my current system, i see many lines of this:
[ebuild   U] sys-apps/tar-1.13.19-r1 to /
[ebuild   U] sys-apps/sh-utils-2.0j-r4 to /
[ebuild  R ] sys-apps/watchpid-0.1-r1 to /
[ebuild N  ] app-editors/nano-1.0.3-r1 to /
[ebuild  R ] sys-apps/tcp-wrappers-7.6-r2 to /
[ebuild   U] sys-apps/grep-2.4.2-r4 to /
[ebuild  R ] sys-apps/texinfo-4.0-r2 to /
[ebuild  R ] sys-devel/autoconf-2.13-r2 to /
[ebuild  R ] sys-devel/automake-1.4-r2 to /

Q1:  what does the R stand for?  i'm pretty sure i understand N and U, and
my first guess for R would be 'remove'.

lets say i:
$cd /usr/portage/sys-apps/grep
$emerge grep-2.4.2-r4.ebuild
$ebuild /var/db/pkg/sys-apps/grep-2.4.2-r3/grep-2.4.2-r3.ebuild unmerge
$emerge --pretend update | grep grep
[ebuild  R ] sys-apps/grep-2.4.2-r4 to /

Q2: porque?

the answer to Q1 will likely explain Q2, i'm hoping. :)



thanks,
j

no, the only way to remove a package right now is this
"ebuild /var/db/pkg/<cat>/<pkg>/<ebuild> unmerge"
you cited.

it just means "remerge", i.e. build and install again with your
new USE flags and the like.

Is there a switch to tell emerge update to not remerge existing packages,
but to only emerge newer packages?

Please note as of today (23 Aug 2001), "emerge update" is experimental and
doesn't always get things right.  That's probably why it is remerging several
packages that have already been installed.

ah, good.  i should have guessed there would be a provision for this.

> hth and is adequate

it helped (thanks!), but there's more. :)

is there something special i have to do to 'remerge' an ebuild correctly?
i have tried a simple emerge of the most recent grep.x.ebuild a number of
times, but it continues to show up with the R.  do i have to first update
everything before it?

if so, someone should probably change this:
ftp://ftp.ibiblio.org/pub/Linux/distfiles/file-3.33.tar.gz
to:
ftp://ftp.ibiblio.org/pub/Linux/distributions/gentoo/distfiles/(etc)
since ftp.astron.com only has file versions 3.35 and 3.36. ;)



thanks again,
j

afaik, that's not the name of the game, because:
generic example:
--package foo is up-to-date
--package bar gets updated
--foo depends on bar
if package foo needs e.g libs from package bar and bar
gets updated, foo is up-to-date only formally, i.e. the ebuild and
the sources are, but foo has to be recompiled
against the libs from bar nevertheless.

well, as a first hint, read my answer to tom's question, which was a 
reply of my reply to your first posting.
the "R" will always show up, as long (as your grep is in
your /etc/make.profile/packages or depends on one of them)
# do i miss something here ?
_and_  your installed version ebuild is the latest non-masked.
if there is a newer one, it will show up as "U".
if you don't have it all, it will show up as "N"
(yes, i know you guessed the last two ;-)
