[gentoo-user] Use Flags

[Silvio Siefke]

Hello,

after longer time want update my Gentoo PC. But ever come error msg with 
the USE Flags. I not know what say me Gentoo with the message.

Hi,
  The above messages is telling you that, if the 'mikmod' useflag is set
the 'mod' use flag neeeds to be set too.

You need to add the 'mod' useflag like this.
                                
media-libs/sdl-mixer mikmod wav mod -flac -fluidsynth -mad -midi -modplug -mp3 -playtools -smpeg -static-libs -timidity -vorbis

[gentoo-user] Gentoo package database

[ivan ivanov]

Hello, list. I am interesting how to find the package that contains the 
file that i want to have in my system.
Let's suppose that latex tells me: File upgreek.sty  not found. To solve 
this i need to install dev-texlive/texlive-latexextra. But, if i do not 
know this, i have to search the appropriate package. On debian i can 
easily do this by visiting official database 
http://www.debian.org/distrib/packages . On archlinux i can use "pkgfile 
upgreek.sty" that searches through NOT INSTALLED packages.
I found site http://www.portagefilelist.de/ that does this job for 
gentoo. But, as i suppose, it is third party project.

I cannot believe that such great project as gentoo does not have 
OFFICIAL database, that allows to search package by the file name.

So, the question is: how to find the name of NOT installed package that 
provides  needed file?

First of all:

DO NOT HIJACK THREADS.

You replied to an existing thread, changed the subject line, deleted
the content and type your question. This is a big nono and is
considered exceptionally rude (it makes everyone else's mail client do
strange things with displaying threads). To start a new thread, compose
an entirely new mail and address it to gentoo-user@lists.gentoo.org

To answer your question, what you want cannot be reliably done. This is
because of how Gentoo works.

In Debian for example, someone else builds the packages, they know
exactly what files will be installed ahead of time, and can put them in
a database for you to query.

Gentoo does not work like that. You build the packages, you specify the
USE flags and different flags can easily cause very different lists of
files to be installed. So the only person that can know exactly what
files you will install is you, there cannot ever be a 100% correct
database of this. Trust me, this has considered many times, you are not
the first.

http://www.portagefilelist.de/ is your best bet, it doesn't get better
than that.

Actually, for the special case of latex packages, his best bet is
dev-tex/texmfind.

No probs.  Most of us use plain text, threaded display in our mail/news 
clients and hijacking a thread breaks the thread up.  Not nice when one tries 
to search through past threads for answers and comes across unrelated content.

At least you don't use HTML and you don't Top Post.  So you got 2 out of 3 
deadly sins right.  ;-)

Your USE for media-libs/sdl-mixer has this: "mikmod -mod"

The system wants "mod" if "mikmod" is set, or both to be off.

Add this to /etc/portage/package.mask:


media-libs/sdl-mixer mod

Don't you mean /etc/portage/package.use   not .mask ?

[gentoo-user] USE Flags

[Vlad Dogaru]

[-- Attachment #1: Type: text/plain, Size: 415 bytes --]

Hello,

First time poster, so if I mess up anything do tell me. I have been emerging
packages and trimming the USE flags individually by adding USE=" " in front
of the command. Is this bad practice or in any way different to adding the
use flags in /etc/portage/packages.conf? If it is, is there a way of dumping
all the use flags for all my currently installed ebuilds into packages.conf?

Thanks in advance,
Vlad

Yes this is very bad practice, which you'll notice if you try 
running 'emerge -avuDN world' to update everything.

Put global USE flags in /etc/make.conf and package specific use flags 
in /etc/portage/package.use

Read through man 5 portage.

Yes, it is bad practise because they are not re-used next time you emerge that 
package.

It's /etc/portage/package.use.

None other than using an editor or 'echo "blablabla"

You really don't want to do that. you'd end up with an unmanageable mess
that completely overrides /etc/make.conf and your profile.

If you run "emerge -puvDN world" you'll see all packages that are
installed with different USE flags to the current settings. Add these
to /etc/portage/package.use.

I think this is exactly what I was looking for. I already have quite an
extensive global USE list (read through the whole list and set/unset what I
knew about). I only need to write the different, package-specific ones.

Thanks to everyone for enlightening me on the issue,
Vlad

To manage the global use flags, try profuse, it's a pretty good editor imho.

[gentoo-user] USE flags

[Goran Maksimoviæ]

I saw that there was a discussion about USE flags and I would seek your advice
on that matter. I recently installed once again Gentoo 2006.0 but before this
version a few months' ago I installed and for a short period of time used Gentoo
2005.0. At that time I had trouble with USE flags because I have never known
what is the best configuration of USE flags for my system so I would like if
someone could help me in a way that he proposes to me a list of flags that i
should have in my make.conf and that that I should exclude. My needs are that I
have a system which is desktop oriented with KDE and not GNOME but also I will
do a little of programming and I will have a experimental web, mail, ftp, MySQL
server because I will learn php. Graphics, games and so on aren't of interest to
me and only thing I want is to play DVDs, DivX movies, play MP3 and audio CDs
and burn DVDs and CDs.

Well, when I installed Gentoo 2006.0, I used the GRP and Dynamic Stage
3, so, couldn't set my USE flags.

I don't set USE at make.conf. After the GRP install, I sync'ed, then
issued a "emerge -uDNpv world" and started "emerge -pv"ing each
package in the list, checking USEs and writting them to package.use.
After that, each and every package installed follows the same path.
This way you don't loose control over your flags and avoid useless
stuff (like compiling a lot of programs with KDE support when you only
need kde-base because of K3B).

It's just the way I do it, any comments? (no flames please, I'll not
change my mind :)

That is pretty much what I do, except that I also take the additional
step of having "-*" for USE in my make.conf to disable anything that
the profile adds by default.

Goran, I would say the most critical flags you want set are:

alsa arts kde hal mp3 ssl truetype dvd dvdread dvdr

Most other flags I would add per package.  Especially I recommend not
adding apache/php use flags to make.conf, but to have those for
specific packages in package.use.

Yes, I have also installed Gentoo 2006.0 with Gentoo LiveCD and installed
GRP packages which were on CD but now I want to set USE flags to avoid what
you have mentioned a installation of stuff which i will not use but which
are installed with packages I install. So once again I am looking for some
assistance in configuring my USE flags in make.conf to needs that you can
read in this mail. I would be grateful to all who help with their lists :).

Well, when I installed Gentoo 2006.0, I used the GRP and Dynamic Stage
3, so, couldn't set my USE flags.

I don't set USE at make.conf. After the GRP install, I sync'ed, then
issued a "emerge -uDNpv world" and started "emerge -pv"ing each
package in the list, checking USEs and writting them to package.use.
After that, each and every package installed follows the same path.
This way you don't loose control over your flags and avoid useless
stuff (like compiling a lot of programs with KDE support when you only
need kde-base because of K3B).

It's just the way I do it, any comments? (no flames please, I'll not
change my mind :)

Well, you could, but then portage would have decided to not use (some of) 
the available binary packages (since they had different USE settings).

That's roughly the way I do it.  Although, initially I started with 
stage1...  In any case, I just do regular 'emerge -avtuND world's and make 
sure and read the USE flags there.  Paying /particular/ attention to 
yellow (new) or stared (changed) use flags.  Also, after any change 
to /etc/portage/package.use or the USE variable in make.conf, I do a 
emerge -avtuND world.

Occasionally, I'll notice some feature I want is missing, them I emerge -pv 
or equery u the package to check use flags to tweak.  If the use flag 
doesn't jump out at me, I might continue with a grep against use.desc and 
use.local or a emerge -pve package (in case the functionality is actually 
missing from a dependency).

I used to be fairly religious about putting global use flags in make.conf 
and package-specific use flags in package.use -- I no longer do this since 
the gentoo developers are nice enough to rarely overlap local use flags, 
so I can just stick everything into a gargantuan USE variable in 
make.conf.  It's easier that way since I manage my use flags with euse.

[gentoo-user] USE flags...

[Eric Waguespack]

say for example I installed Gentoo with some USE flags, but then I
changed my mind and wanted to add (for example) the "offensive" USE
flag to my make.conf (I have no idea what offensive does, but with a
name like that, it must be good http://gentoo-portage.com/USE ). what
would I do (short of a reinstallation) to recompile everything with
these new USE flags?

emerge --newuse world (or, emerge -N world) will search through your
installed files for the packages that can use that flag and recompile
them with it active rather than inactive.

(man emerge might be worth a look)

No it won't. You need to add --deep and --update to catch everything:

The short options make for easier typing, the long ones for easier
understanding. So I use the short options at the command line but the
long ones in scripts and examples.

Offensive turns on, well, possibly offensive content. For x-screensaver, 
one of the screensavers grabs images off the internet and make a mosaic.
Turning on the offensive flag means you might get porn and/or goatse 
in there. For fortune, that enables the -o option, which produces insults.

I know sudo insults you if you type the wrong password, and I remember
the controversy over the Windowmaker themes package (which was an
unchecked compilation of previously-existing themes, some of which
contained wallpaper featuring nudity-- female, of course-- which was put
under the 'offensive' flag not only because it might be personally
offensive, but because you might be installing Windowmaker at work, and
a random wallpaper or theme change might put you out of a job without
you being aware of the possibility that that could happen).

The others I don't know personally, but are likely similar to one or the
other of these cases as appropriate.

[gentoo-user] USE flags

[John Dangler]

I have just installed a basic 2005.1 system (2.6.12-r6) on my laptop.  I'm
trying to get my arms around the USE flags.  I found a set of 'default'
settings (I think) under /usr/portage/profiles/base/use.defaults .  From
what I've read in the gentoo documentation, this seems to be a list of
default USE= flags.  What I'd like to try and get to is, a difference
between what's there and the 'total' list, and why would I add others to my
own make.conf file?

Thanks, as always, for the input.

RE: [gentoo-user] USE flags

[John Dangler]

The list of possible flags is somewhat overwhelming.  And many of them, I
wouldn't really know if I need them or not.  So far, since I only have the
base system running, I'm trying to get everything I want to have sans a
graphic environment going, so I'm doing USE="-X" with the system level apps
(although I don't know if that's the best plan for something like
cdrtools/dvdrtools).

I did find the defaults (thanks!) and have added those as comments in my
make.conf file just for my own reference.

I figure that the next step (aside from the reading of the online docs) is
to get cd tools and anti-virus (clam looks good) running.

At the point that I think I have everything at this level, I intend to back
it up (jic), and then install X, sound, and get a graphical environment
running - at least that looks to be the most logical next steps...

I really appreciate the feedback!!!

The way dependencies seem to work with portage, I wouldn't bother "installing 
x".  Just install say kde or gnome or whatever (see the docs) and X will be 
installed and configured automagically.  for instance, I installed this dell 
laptop, then emerged kde-meta (be patient if you try that...my poor celeron 
took 16 hours to do that) and followed the documentation for kde on the 
gentoo site and it's all happy...except sound works in xmms, but not kde 
sytem notifications....not sure why, but it's at the BOTTOM of my list.

  The default settings for X86 machines using 2005.1 is the sum of base,
default-linux, default-linux/x86 and default-linux/x86/2005.1.  It's the
developers' attempt to be all things to all people.  However, one size
does not fit all.  For instance default-linux/x86/make.defaults contains
the statement...

USE="alsa apm arts avi berkdb bitmap-fonts crypt cups eds emboss encode fortran
foomaticdb gdbm gif gnome gpm gstreamer gtk gtk2 imlib ipv6 jpeg kde
libg++ libwww mad mikmod motif mp3 mpeg ncurses nls ogg oggvorbis opengl
oss pam pdflib perl png python qt quicktime readline sdl spell ssl tcpd
truetype truetype-fonts type1-fonts vorbis X xml2 xmms xv zlib"

  While the KDE and GNOME people make some great *APPLICATIONS* (e.g.
Koffice, Gnumeric, AbiWord, etc) their "desktop environments" are fat,
bloated, resource-hogging, eye-candy that accomplish nothing other than
to make a P4 emulate a PII with half the RAM.  I don't want the "gnome"
or "kde" flags.  That means dumping the "arts" flag, because ARTS
depends on KDE and building ARTS will result in building KDE.  Why is
"oss" in there as a flag, given that OSS is deprecated?

  PAM is a good idea for somebody running a server with multiple
external users accessing it.  IMHO, PAM belongs in the optional security
packages, with hardened linux, and NSA SELinux.  For the average home
desktop, PAM is a PITA.

  The 90%+ of the online world that doesn't use IPV6 can do without the
"ipv6" flag, thank you.  When the "ipv6" flag was introduced, a lot of
people noticed their internet apps would sit there for 90 seconds, time
out IPV6, and then try IPV4 addresses... oops.  To block that, put
"-ipv6" in your USE.

  My approach is to use "-*" which zaps all flags, then specify the ones
*I* want/need.  If a particular package wants/needs a specific flag, hey
that's what /etc/portage/package.use is for.  If enough packages need a
specific flag, I'll think about adding it to my USE variable.  Here's
what I have...

USE="-* a52 aac alsa apm audiofile dio encode exif ffmpeg flac foomatic fortran gb gif gstreamer gtk2 ieee1394 jpeg maildir mikmod mmap mmx mng ncurses offensive ogg opengl plotutil png posix quicktime sdl slang sse sse2 theora threads tiff truetype vorbis win32codecs wmf xv" 

  Your specific needs will differ, depending on what *YOU* run on your
machine.

I believe it takes the default USE flags from 
/usr/portage/profiles/default-linux/x86/make.defaults (since I am on a x86)

The way the system works is that it applies those default USE flags 
unless you say otherwise. The way to alter the default USE flags for 
your system is to edit your /etc/make.conf and make 
additions/subtractions from the USE flags. Basically this is a way to 
customise your system to the way you want it.

This site shows them all and a brief description

http://www.gentoo.org/dyn/use-index.xml

The best way to see what USE flags are currently set is
# emerge info
as this takes into account the defaults and all the changes you have 
made through /etc/make.conf

For instance in the default USE flags has

USE="alsa apm arts avi berkdb bitmap-fonts crypt cups eds....(many more)"

If you don't have a printer on your system, there is little point in 
having cups as a USE flag (it will add unnecessary time to compile your 
packages). So in your /etc/make.conf file you can put

USE="-cups"

Same thing if you don't want to use kde, and say you want to have 
mozilla support on your system as well you would end up with.

USE=-cups -kde mozilla"

Then if you run
# emerge info
again it will have removed cups and kde from the USE flags and added 
mozilla to the list as well.

Hope that helps
Peter

Hello,
        This looks like what I am leaning towards.  Now I just have to find 
out what those few critical flags are ;o}  Thanks all!

Hello,
        I found this below at 
http://www.dslreports.com/forum/remark,11993814: USE="-* tcpd crypt ssl pam 
ncurses zlib readline".  Does it look as minimalistic *and* safe as 
possible?

[gentoo-user] USE flags...

[Vincent A. Primavera]

Hello,
        Just looking for some opinions here.  What is a good approach to 
installing applications with a minimal amount of optional USE flags enabled? 
For example, if one were to run `emerge -pv kde-base/kde` you would be 
presented with many, many dependencies and USE flags.  I would prefer to 
install less upfront and add on later as needed.  Doing an `emerge -pv 
$packagename` then looking through the dependencies and their USE flags each 
time, to me, doesn't seem like the best method.  I took a look at the list 
of USE flags at http://www.gentoo-portage.com/USE and disabling dozens of 
them in /etc/make.conf doesn't seem like a great method either.  I'm trying 
to avoid a big, bloated system without going too crazy here.  Any 
suggestions?

Your problem is going to be the incremental enabling thing you'd like to do.
If you add a new USE flag later on, you need to emerge with the newuse flag
which will result in a larger emerge than what you expect.

For example, if you build your system then add the alsa use flag and emerge
with newuse, you'll basically be rebuilding X, kde and/or gnome, etc.  A
huge task for such a simple flag addition.

Your best bet is to determine the use flags that you intend on using in the
final system and be selective about what you emerge to keep the system size
under control.

Unless, of course, you don't mind recompiling big parts of the system for
use case changes...

Hi,
Recently there was such discussion, only about the default USE-flags (in
current profile).
By memory the solution was: "-* only desired USE-flags here, ex. alsa
crypt readline ..." in '/etc/make.conf'
"-*" disables quite all (only all optional w/o the required ones) and
turns ON the USE-flags following it.
PS: watch out there are 2-3 flags which are absolutely required for a
sane system, check ML-archive (readline is one).

Hi,
regarding kde, you might want to try the split ebuilds if you haven't 
heard of them before:
http://www.gentoo.org/doc/en/kde-split-ebuilds.xml

About the USE flags, sorry i have no better sane solution to your 
problem than to disable all at the beginning and then incrementally 
enabling more when you need them...
