[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.

gentoo-desk ~ # emerge -uDN world
Calculating dependencies... done!

!!! The ebuild selected to satisfy "media-libs/sdl-mixer[mikmod]" has unmet requirements.
- media-libs/sdl-mixer-1.2.12-r1::gentoo USE="mikmod wav -flac -fluidsynth -mad -midi -mod -modplug -mp3 -playtools -smpeg -static-libs -timidity -vorbis"

  The following REQUIRED_USE flag constraints are unsatisfied:
    mikmod? ( mod )

  The above constraints are a subset of the following complete expression:

(dependency required by "games-kids/tuxmath-1.7.2" [installed])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument])


gentoo-desk ~ # cat /etc/portage/package.use | grep sdl-mixer
media-libs/sdl-mixer mikmod wav -flac -fluidsynth -mad -midi -mod -modplug -mp3 -playtools -smpeg -static-libs -timidity -vorbis

I understand not what want me say the system?


Thanks for help.

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.

Yes, that is very annoying.

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

Interesting, I didn't know about that one. 

I'll have to make a note for future use

  Sorry, i did not know this. I never encountered such behavior on other 
mailing lists.

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 ?

Yes indeed, that's what I meant. Good catch :-)
