Did you have 'dvd' in USE ?  If so, do:

And mail me the log.

[gentoo-dev] mplayer with dvdread

[M. Zuelsdorff]

my experience with emerging Gentoo's Mplayer 0.90rc4 out of the box was:

no DVD in the graphical menu.
And Martin Schlemmer's "gmplayer -dvd 1" here ends with a:
"MPlayer was compiled WITHOUT libdvdread support!"

That's why I did another installation manually in /usr/local/... feeding 
configure with the appropriate parameters in advance. This version works.

hmmm .... very interresting ... 

when I did this on the original box it only compiled mplayer ... on this machine it now wants to install all the dvd libs.

I'll play on the old box again and mail some info .. 

Is the libdvdread and libdvdcss that gets included with USE="dvd" the default libs or just themplayer libs that are stripped out ? 

If so my question about the comments in the mplayer docs still stand about using the default libs resulting in slower performance, bugs and library 
incompatibilities ..

RE: [gentoo-dev] mplayer with dvdread -- use flag comment

[Riyad Kalla]

I'm starting to feel more like this, WGT the use flags... when I
installed gentoo on a server here at work, I left the use flags alone,
figuring "hey it's a server" but then I noticed that certain packages
WANTED to install some rediculous amounts of optional requirements, so I
started using "-" use flags, and that seemed to work. Then I noticed
other packages building without supports for things I needed (like
CUPS). Anywya, after compiling and recompiling KDE about 3 times, mysql
twice, qt 3 times and a few utilities I started to think that before
installing a program, I'd rather just see the "configure --help" options
and decide what I wanted and what I didn't... this use flag business is
kinda trickie... I couldn't imagine trying to code to take it all into
account. Has there ever been talk to get rid of use flags and tackle
optional package params in a different way?

The logic was that if 'foo' is in USE, then support for 'foo' gets
build.  If 'foo' not in USE, then support for 'foo' gets disabled.

I think you really need to go and do some reading, and re-evaluate
your stance to using USE ...

The logical would have been:

  - I want a server, so no X, sound, KDE, Gnome, etc, so add
    to USE: -X -gnome -kde -xv -alsa -oss -esd -avi -mikmod -mpeg
            -oggvorbis -opengl -qt -quicktime -sdl -spell -svga
            -truetype -xmms
  - It will be samba print server, so we need cups, so add: cups
  - etc

So USE will be:

USE="-X -gnome -kde -xv -alsa -oss -esd -avi -mikmod -mpeg -oggvorbis
-opengl -qt -quicktime -sdl -spell -svga -truetype -xmms"

No cups is needed, as its already in the default USE flags.  What
those are, look at:

  /etc/make.profile/make.defaults

Note that you should not edit this file by hand.

RE: [gentoo-dev] mplayer with dvdread

[Riyad Kalla]

Martin,

Your comment makes it sound like leaving foo out of USE is the same as
"-foo"... but I get quite a different story. I would actually prefer
that USE behave in such a predictable manner, either meaning that not
including foo in the USE automatically includes foo features or
automatically disables foo features, but I found that its completely
unpredictable... let me use QT as an example:

with NO use flags, qt compiled (for me) without GIF support and without
CUPS support (these two I paid attention to in particular, but I'm sure
lots of other build flags got changed too).

When I saw this, I emerged cups and gif, then built QT again (without
changing USE flags). Same thing, still no GIF or CUPS support. So I
added "gif" and "cups" to use and it worked fine.

What I just described agrees with your comment, but when I was building
KDE, I noticed quite a few gnome and gtk dependencies... then I went and
added "-gtk" and "-gnome" to my use flags, and the deps went away (I'm
not 100% if it was KDE or not, but that's beside the point, the point
was that I had to explicity tell emerge NOT to include gnome or gtk
deps, yet I also had to tell it to explicity INCLUDE the cups and gif
deps".

This behavior confuses me, as I never know "what I'm missing" so to
speak until its too late. Is there a way to make emerge behave more
predictably? Either by automatically excluding ALL possible use flags
unless stated otherwise, OR by including all possible use flags unless
stated otherwise?

A gentleman on this list (Sami) gave a good suggestion to me which was
to add ALL of the use flags in alphabetical order to my USE variable,
then run down the list adding a "-" before each one I didn't want. This
seems to be the only way to garuntee the behavior... which is suboptimal
at best.

Thoughts? Comments?

Best,
-Riyad

RE: [gentoo-dev] mplayer with dvdread -- use flag comment

[Riyad Kalla]

After reading your email I found out what was causing my hearache
(make.defaults)! I hadn't thought about checking that as I didn't
realize the use flags were hierarchical in that fashion...

Does make.defaults include all of the use flags? If I modified
make.defaults (I know you just said not to, but...) to either include
nothing, or include everything, wouldn't I effectively be implementing
the behavior I just asked for? And then fine tune it with my make.conf?

Thanks!

Re: [gentoo-dev] mplayer with dvdread

[M. Zuelsdorff]

No, I don't make use of "USE" at all, since it's one of the really annoying 
parts of the Gentoo distribution. There are thousands of packages in the 
portage tree but not a single line on which USE-var is related to which 
package.
All I was able to find was: "dvd adds support for DvDs". Fine. I'd never 
thought that DvD support is disabled by default in a tool like Mplayer. And 
in fact it is NOT, when I get the tool from the mplayer site, directly. So, 
what is it worth this extra little fuzz? In the end, an experience like this 
can only lead to a blind "better enable everything" since no one is able to 
keep track of all bells and whistles each package comes with. And this way 
making the USE mimik more or less obsolete.

Best regards.

See, because there was a problem with new users that they did not add
USE flags for common stuff, and then was upset later on, we added
'default' use flags ...  You can view them with:

 # grep -A 3  USE /etc/make.profile/make.defaults

To start with a clean slate, do in /etc/make.conf:

----------------------------------------------
USE="-* whatever_USE_flags_you_may_want"
----------------------------------------------

The '-*' means to remove all default USE flags defined in
/etc/make.profile/make.defaults ...

Hope this clears some issues.

You are in luck.  This afternoon I finished a program that creates a list 
of 
which packages are associated with which use flag and vice versa.

The code is not quite ready for prime time so I don't want distribute the 
source yet. But if you or anyone wants a copy or the output let me know
and I will email you a copy off-list (its 85K).

No, just ones we think is ok for a generic desktop system with nice

If you do not just want to '-foo' the flags you do not want, do in
/etc/make.conf:

----------------------------------------------
USE="-* whatever_flags_you_want"
----------------------------------------------

Where the '-*' means to remove all the default USE flags.  Do not
edit make.default directly ....

Sorry for replying to myself but the code is complete and attached to this
email.

To run either type:
     perl extractuse.pl
or set the executable bit and run it directly.

It will print to stdout 2 lists, the first is a list of packages and the
use flags associated with them.  The second list is of the use flags
and which packages use them.

You will probable want to redirect the output to a file or use
a pager, the output is > 3000 lines.

Depending on the speed of your machine it can take a couple of 
minutes before it produces any output so be patient.

Enjoy
