[gentoo-user] USE flags handling

[gentoo-user] USE flags handling

[behrouz khosravi]

Hello everyone.
I just concurred my fear and jumped to installing gentoo!
So far so good!
Before installing on my laptop and desktop, I am trying on virtual box
and the system is running Fluxbox very good.(default profile)
Now I am thinking about managing USE flags.
What if I  disable everything in the make.conf ( I mean USE="-*" ) and
gradually add the needed flags to package.use?
I am not trying to have severe control, I just want to expand my knowledge!
thanks.

Yes, it's not difficult, but it's a sort of initiation test.

Yes, Fluxbox is less well-known than it should be : it's excellent.

That's what I've done for years, but others will react in horror (smile).
It's ok, provided you check the use flags for applications,
whenever you emerge new versions : occasionally otherwise, it can hurt.

> I just want to expand my knowledge!

This is a very polite & friendly list with good advice available.

I suspect that may be true of a majority of Gentooers :
we're all used to interpreting others' words
& trying to be careful to be clear when we do know English well.

From the discussion so far today, you sound like a born Gentoo user.

English is the only language I know and even I mess it up at times.  So,
we all have to read between the lines at times.  ;-)

True but sometimes, I suck at it.  For the record, I am bad to leave the
word "not" or "n't" out.  Talk about a monumental change in meaning. 
ROFL   Imagine talking about the command rm and leaving that out.  o_O 

Still, I think we do our best when someone posts and English is not
their first language.  I know it is hard sometimes for people to post
and get it right but still, we all try.

You may well break your system, but you get to keep the pieces as a
lesson.

Portage profiles set some default USE flags, then some ebuilds also set
defaults. Using USE="-*" disables all of these. You can see the defaults
by looking at the output from emerge --info with no USE defined in
make.conf.

> I am not trying to have severe control, I just want to expand my

You will do that, but not in the way you hoped. Pick a profile that most
closely matches your usage and then find tune from that by adding or
removing USE flags. That's a lot easier than deliberately breaking things
and then trying to work out how to fix them.

Also, when setting up a new system, make USE flag changes gradually.
Unless you are sure of what you are doing, only change a few at a time.

Haha, just got frustrated with how much junk is on my machine and 
globally disabled perl, python, ruby, and a bunch of other stuff. Bad 
times ensued ;).

But really, as long as you're fine with looking at failed builds to see 
what went wrong, you should be fine. You can set PORT_LOGDIR in 
make.conf to send all build logs into a location (mine is 
/var/log/portage) so that all logs get saved automatically, which I 
find helpful.

I have noticed that some packages have flags that I have not set, but
I though that they were the default flags for that package. You mean
those flags will become persistence? Will be them written to a
specific file?

I guess your way is better. I think it will be a good idea to stick to
the base profile, and define the required flags as locale flags.

  Here is a compromise.  I started with USE="-*" and then gradually
added stuff that was needed by most items.  My rule-of-thumb is...
If adding a flag to USE reduces the number of entries in package.use,
then I add it.  I.e. if...
* not having flag "foobar" in USE requires 6 entries in package.use, and
* having flag "foobar" in USE requires only 2 "-" entries in package.use

...then I move flag "foobar" into USE and put a few "-" entries in
package.use.  I do want stuff like "ncurses nptl nptlonly posix readline
threads" for every app which can use it.  Similarly, cpu-specific flags
should be in your USE.  This effectively gives you a very customized
profile.  By the way, you can make your own variables in make.conf, and
concatenate them, like in bash.  In my make.conf I have...

USE_BASE="-* a52 aac bzip2 cxx fortran ncurses netifrc nptl nptlonly nsplugin offensive openssl posix readline ssl threads vim-syntax zlib"
USE_CPU="mmx mmxext sse sse2 sse3 ssse3"
USE_VIDEO="X dga dri exif ffmpeg flac classic gif intel jpeg mng mp3 mpeg ogg opengl png rtmp theora tiff truetype vorbis xcomposite webm x264 xpm xv xvid xvmc"
USE="${USE_BASE} ${USE_CPU} ${USE_VIDEO}"

  I can mostly copy this to another machine.  ***WARNING*** the flags in
USE_CPU are specific to, and have to be customized for, each machine.
My Dell Dimension 530 dates back to June 2008.  Newer Intel machines
will have additional cpu-specific flags, and AMD cpus will have their
own unique additional flags.  Your set of flags may be different,
depending on what applications you use, and what you want to do with the
machine.

Here's very good advice for the OP:

Do not do this. Walter does it, and he finds it works for him. He's been
doing it for years and nothing will persuade him to do it any other way.

You should not do with USE what Walter does. Trust me, it will lead you
down a path of immense pain that you do not have the tools to get out
of, and when you ask here for help you will be told to take that -* out
of USE.

No offense Walter, but this is really bad advice to give someone brand
new to Gentoo. He really is ill-equipped to deal with it, and USE="-*"
is best left to those who fully understand exactly what they are getting
themselves into.

Re: [gentoo-user] USE flags handling

[behrouz khosravi]

Thank you all.

I have concluded that I should stay with the base profile. Although I
need a desktop, but this decision will be closest to what I want in a
harmless way! (at least less harm!)
Then I will add CPU specific and very frequent flags to make.conf and
gradually extend the package.use file.

The way that you have managed the USE flag is neat, and I will do the same.

Howdy Behrouz,

Gentoo is a very wonderful OS, and we have lots of "Special" folks
that are very capable, wise but often tainted, as you will discover.

Walter, like myself, is a minmalist. Others are right too, that your first
journey into "Gentoo" you need to follow the beaten path for a while
before you venture out, naked and alone. We've all borked a system or 2,
some abuse the that honor........

YOU have chosen a somewhat minimalist path with your desktop, wisely
avoiding "bloat_ware_city". But, to avoid pain do keep some minimal 
collection of flags. Python is CRITICAL on gentoo, so ask before 
verging out on Python!

 Look at the defaults for your selected profile and what Walter has
suggested. jArch_Linux documentation is often useful too. When in doubt,
keep the flag, until you are assured it's removal will not result in a
broken (borked?) system. You have a lot of reading to do on the
www.gentoo.wiki and other gentoo pages (here are a few)

man euse   (euse -i <flag>   and euse -<flag>) 
eix <package>          (man eix)
man equery

gentoolkit  (is your swiss army knife for gentoo)

http://www.gentoo.org/dyn/use-index.xml#doc_chap1

http://wiki.gentoo.org/wiki/OpenRC
(hopefully, you are using openrc and not systemd ?)

http://swift.siphos.be/linux_sea/

(Sven is a great human! He not only overseas much of the documentation,
he one of the SeLinux folks, should you venture into those waters)

This is not a complete list of good reading by any means, but a start.


good hunting!
James

Bear in mind that USE flags control *optional* features and dependencies.
Setting USE="-python" will not prevent python being installed, nor will
it break portage, but it will "de-bloat" those packages that come with
optional python interfaces and bindings.

One USE flags that new users often select, mistakenly, is doc. Package
documentation such as man pages, info pages and readmes is installed by
default. The doc USE flag enables the building and installation of
developer and API documentation, and usually comes with a swathe of
dependencies. It should never be enabled globally.

and it might break packages in features in surprising ways.

People who tell newbies that -* could be used at all, should be flogged.

In a public place. With video.

This 'de-bloat' crap - who came up with that? People who use it all the
times seldomly realize that the 'small and unbloated' software they use
is in a lot of cases neither small, nor not bloated.

Usually it comes from the same headspace that ricing comes from. Humans
are all about perception, very very very few of them can actually look
at things in an unbiased way. So it goes like this:

User hates Gnome. [opinion]
User decides that because Gnome integrates so many things vertically
then Gnome must necessarily be bloated. [invalid conclusion not backed
up by facts]
User decides to try Razor|LXDE|Enlightenment|*box|whatever [valid activity]
User likes <whatever> [opinion]
User concludes that <whatever> is therefore "better" than Gnome
[erronously equate specific opinion with fact for the general case]
Therefore <whatever> is not bloated and Gnome is, to satisfy wrong
conclusion at #2 [I can't even begin to think what fallacy this is]


Not much opinion in any of that.
We humans are mostly hard-wired to react based on past experience and
data blindly accepted as fact in the past. 9 times out of 10 this helps
you leap out of the way of the tiger seeking to have you for lunch. You
got this ability from dad's genes and it must be raising the odds for
you and he otherwise he wouldn't have survived long enough to sire you.
If you stop to think about the tiger, he is for sure going to have a
nice lunch. So we humans that survived did so by jumping to conclusions
and having them work out OK on average. This new-fangled idea of
actually thinking about things all the way through is a very new idea,
and most of the species hasn't gotten the hang of it yet.

So now you know why ricers swear blind that -pipe in CFLAGS "*doubles*
the running speed, dude!"

This does still seem to be a valid survival requirement for a large part of 
the worlds population though, including where you are.
For people living in a "so-called" civilized world, tigers are only found 
inside places commonly called a "zoo" :)

Small software can be bloated, large software can be bloat-free. It's all
about what is useful. "functional" != "bloated", but all too often
"lightweight", "bloat free" software can also be described as "limited"
or "functionally challenged".

That is true.  Some code can be really small and do a lot.   Same can be
said for the opposite.

Maybe this comparison will work.  Small and gets the job done. 
Bicycle.  Bloated.  18 wheeler truck.  If all you want to do is ride a
relatively short distance with no load, bicycle will get the job done.
It won't do well if you want to move 20 tons somewhere tho.  The 18
wheeler truck is good if you need to pull 20 tons somewhere but is a bit
bloated if you are just going to ride up the street to see a neighbor. 
It's also a bit harder to park too.  ;-)

While to me KDE is bloated, I just try to disable what I can and carry
on.  If my system was limited on resources, then I may use something else.

and maybe you did exactly the wrong thing. KDE is very modular and
reuses its modules as much as it can. Which also means: memory is only
used once.

There were once a very good (in my not so humble opinion. It think very
highly of myself) comparism here:

http://ktown.kde.org/~seli/memory/
(url is dead btw)

and if you actually use kde apps in kde - memory consumption is lower
than in either gnome or 'leightweight' solutions like xfce or
windowmaker+stuff.

The biggest thing for me, is just stuff I don't use or ever see me
needing.  At one point, can't recall version, KDE4 was a bit of a memory
hog.  It seems they have cleaned that up a lot since tho.  Even on my
old rig which had 3GBs of ram and KDE3, it wasn't to bad on memory.  CPU
wise tho, I'd hate to run KDE4 on my old rig.  It is just to slow for
KDE4.

I used to run KDE on a netbook with 2GB and it ran very well. True, LXDE
was faster, but it did less. Not doing stuff faster isn't a benefit in my
book.

That's why I use KDE still.  There are things it does that I like plus
my new rig is fast enough and has plenty of ram.  My old rig tho, not
KDE4.  I don't think I would even try it.  KDE4 is the reason I built
this new rig.

I do have Fluxbox installed tho.  I have been known to use it a few
times too.  It is so fast it is unreal.

  I run ICEWM with 9 work areas dedicated to specific "tasks" or forums.
A desktop environment doesn't provide me that much extra functionality.
I suppose some of my inertia is due to starting to use ICEWM and *BOX
back when I had a Dell with 256 megabytes of RAM and an 8-megabyte ATI
video card.  That machine lasted for 7 years or so.  My current one is
over 6 years old.

On a rig that has limited resources, you are doing what I would do as
well, outside the USE="-*" thing.  :-D  I would use Fluxbox or some
other very light GUI.  I'd keep it simple so that when I click
something, I don't have to go get a drink while I am waiting.  And in
some cases, have plenty of time to drink it as well. 

What a person uses has to be based on what it is being used on and what
the user expects.  All about balance.

There's a huge difference between recognizing a resource-constrained
machine and acting appropriately on the one hand, and ranting about
bloat on the other.

One usually involves sensible thought, the other usually doesn't.

That's basically my experience. I'm impressed with the speed then find I
can't do what I want because the DE just can't do it.

It may not do what I want, but at least it doesn't do it at great speed :(

  The problem with KDE apps is that they're imitating what MS did with
Internet Explorer.  They pointed to the itsy-bitsy-teeny-weeny little
"ie.exe" that you could delete if you felt like doing so.  They
deliberately obfuscated that it was merely a front end to a ton of
system libraries that you could not remove.   Back when xpdf was being
deprecated, various replacement options were suggested.  I chose mupdf
rather than the KDE app "okular".  Here's why.  After multiple attempts
at "emerge -pv okular", I found I had to add at least the following to
package.use to get it to work...

dev-libs/libattica qt4
media-libs/phonon vlc
media-video/vlc dbus xcb -ffmpeg
dev-qt/qtcore qt3support
dev-qt/qtdeclarative accessibility qt3support
dev-qt/qtgui accessibility qt3support 
dev-qt/qtopengl qt3support
dev-qt/qt3support accessibility
dev-qt/qtsql qt3support sqlite
dev-qt/qtsvg accessibility
sys-libs/ncurses unicode

  Seems that if I want to emerge and use KDE's "pdf reader", I need...

phonon
vlc (or gstreamer)
libmpeg
libmad
net-dns/libidn
dev-qt/qtwebkit

okular is not a 'stinking pdf reader'. Nice try. But just like konqueror
it is just a wrapper around kparts and is able to deal with a lot more
files than just pdf and postscript.

That is what 'modular' and 'code reuse' really means.

And the opposite to what gnome does. 'oh, there is an app. Hijack it and
gnomify it and make it dependent on 2 douzend gnome libs that all do the
same but nobody ever cleaned up'.

You're right about the code reuse if you're running KDE, but I'd rather
not install *all* of Qt and a bunch of other crap just to view PDFs and
such. I think that's all he's arguing.

I love having KDE on my desktop (and okular is really nice), but on my
laptop (i3wm) I spend the vast majority of my time in vim and on the
terminal and shouldn't have to essentially install KDE to view a PDF
when I need to check some LaTeX formatting. Just contrast with evince; I
disabled nautilus integration, and my machine only has 5 gnome packages,
2 of which are icon sets.

well, do you complain if you have to install *all* of gtk + gnome

Alright, you got me there. I was a little over-dosed on coffee when I

Unless you meant Blackburn B-25, but then you'd need the carrier to go
with it, and ships are definitely off topic.

  When reading pdf files, one expects images, so tiff and jpeg are
reasonable flags.  One does *NOT* expect audio stuff like phonon.  And
phonon *DEMANDS SOMETHING*.  vlc is one of the options that satisfies
phonon's demands.  Or you could choose gstreamer and its gazillion plugins.

Not quite (smile) ! -- I ran into this & sent bugs to Gentoo + KDE ;
the outcome was that I discovered that Phonon doesn't in fact demand
that you install the actual sound software :
it works to do 'USE="gstreamer" --nodeps emerge phonon'
& Kdelibs then compiles successfully as well.

If you compile KDE outside Portage, there's a "nosound" flag,
but the Gentoo devs have implemented that to require 'USE=<soundpkg>",
perhaps knowing that it cb happily ignored via '--nodeps'.
Just don't expect this to be documented anywere (grimace).

Do you still have the bug numbers for this?
I have a few machines without any sound support. If I can remove the 
entire sound system from it, it would save time during the updates.

Actually, I wasn't ignoring you. It just took some time to find the actual 
cause.
In the settings for KMail, I had the tick-boxes mentioning HTML off already. 
Took me till this morning to notice that in the edit-window, "Rich Text" was 
selected. (It acts like a button that is pushed in)

If anyone can tell me how to configure that to *always* default to *off*, 
instead of remembering the last setting, that would help.

It's been a while since I used kmail (i always had "issues" and ended up
reverting to thunderbird) but i'm pretty certain that the composer
options allow you to disable rich-text for messages (or, conversely,
enable plain-text-only).

it's there somewhere, just dig ;)

I used to use Kmail but switched to Seamonkey.  Don't start.  I might
bite.  :-)  I did some googling and found where some others were
complaining about this setting not sticking.  It seems this is not a new
issue.  One bug dated all the way back to KDE3 stuff.  I found another
that was KDE4 which claims it was fixed, heard that before.  lol 

So, maybe some bug got thrown back in?  If after the next update it does
the same, I throw up a can of Raid. Uh, over at KDE tho.  ;-)

I have sound disabled in the kernel & no sound pkgs installed ;
I have had to install Phonon, but nothing to work with it.
I use several KDE apps, but run my desktop with Fluxbox.

I have no idea what you are talking about.

[I] kde-base/okular
     Available versions:  (4) 4.12.5-r1(4/4.12)^t (~)4.13.3(4/4.13)^t
       {aqua chm crypt debug djvu dpi ebook +handbook +jpeg mobi +pdf
+postscript +tiff}


There's nothing in there about audio or video. There's only images and
of those only 4 rational ones are enabled by default plus the help system.

So what is the real problem exactly again?

  It is a "deep dependancy".  kde-base/kdelibs-4.12.5-r1.ebuild has a
"COMMONDEPEND=" block which includes ">=media-libs/phonon-4.4.3".  And
media-libs/phonon-4.6.0-r1.ebuild has the following line...

So don't blame KDE, blame Gentoo for not handling Phonon correctly :

Had a look myself just now based on your other comments.

KDE actually specifies how to build without any multimedia (audio and video) 
support:

https://techbase.kde.org/Development/Tutorials/CMake#Command_Line_Variables

cmake command line variable:
KDE4_DISABLE_MULTIMEDIA=ON: Build KDE without any multimedia (audio and video) 
support.

  The big question... what is "multimedia"?  Would it be possible to
build kde with image support (gif/png/jpeg/tiff/pdf/etc) without
building in audio and video?  I.e. how integrated is kde's graphics
and multimedia?

The most common definition of multimedia is audio and video. Images is 
generally a different set. Also the description specifies audio and video 
specifically.

It might be useful to modify the ebuild(s) to specify that option and see what 
happens.

But I think that needs to be added to quite a few ebuilds and the related 
dependencies need to be modified as well.

From a quick google for "KDE4_DISABLE_MULTIMEDIA" it looks like that just enables / disables Phonon:

• http://mail.kde.org/pipermail/kde-buildsystem/2010-March/006806.html
• http://www.filewatcher.com/p/kdebase-runtime-4.1.3.tar.bz2.52251161/kdebase-runtime-4.1.3/phonon/CMakeLists.txt.html

I have to confess, I don't follow desktop development to know myself what "Phonon" means.

The page linked to in the package description for media-libs/phonon is, unsurprisingly, uninformative: https://projects.kde.org/projects/kdesupport/phonon

Or follow the links in the kde.org page and after four or so clicks you
end up with the information you expected to find in the first place

OK. But my original point still stands:

Okular is not designed to be a stand-alone app, it is designed to run in
the context of something bigger. And that context is KDE.

KDE is a full-featured desktop environment, it assumes that the user
will want phonon and everything that comes with it, plus plasma. So when
you emerge okular and get a boat load of new deps pulled in, why are you
surprised when that goes the way it is designed, the way it says on the box?

It's not a stand-alone app. This is also not Windows, here you have
choices and there's no shortage of pdf readers out there.

Pick another one

So on that box you wouldn't choose a KDE program. Simple.

I'm going to take issue with this post.

Walter, you have completely misjudged what KDE is designed to do and are
blaming it unfairly. KDE apps are not designed to run in isolation -
they run in a greater context. That context is the KDE system.

It was designed with the view that an app like okular will be installed
alongside other similar apps that let you deal with other filetypes.
Like audio, video, graphics, text. And so on. To do this, it needs the
libs it is built on. And it needs a graphics toolkit - Qt. The reason
you got such a long list of packages to install is because you do not
have any Qt installed at all.

If you did not have any X installed at all and wanted to emerge xpdf you
would get a similar long list for exactly the same reason.

The point I'm trying to make is that KDe was not designed with you in
mind. KDE could never work for you because of your viewpoint and that
viewpoint is in your sig. So please stop blaming KDE for doing what KDE
does correctly and well. Just realise that you are not the target audience.

As an analogy most of the world wants a sedan so Toyota makes the Yaris
for them. You have decided you don't want a sedan but you do want a
crotch rocket, so Honda makes a CBR1000 you might like. Or if acting
like Rossi doesn't appeal, they also make nice adventure bikes. But that
doesn't make the Yaris wrong.

Actually, because governments are trying to get people to move into 
smaller cars, car companies ended up with motorised shopping carts like 
the Yaris.

People who actually need to travel a lot on motorways do tend to prefer 
slightly bigger cars like a VW Golf, Ford Focus or Peugeot 308.
People with smaller budgets then end up with the Polo, Fiesta or 208.

I wish I could take credit for it; it is a very, very popular concept,

Lots of folks have lots of reasons to reduce the space/ram/cup resource
consumption, particularly for things  they do not want and quite often
due to constraints on resources....(ymmv).

The word ricing has a fine honourable heritage from way back many years
ago. But lately it means something else altogether :-(

Much like "hacking"

The default profile is what you need.

Please don't do USE="-*". It breaks things. 

* Long ago, setting a useflag always meant "adding things to the default". For 
some years now, we have use-defaults, which means an ebuild can set whether a 
use flag set not by profile and not by user is on or off. If you add "-*" to 
your use flags, you turn all default-on useflags off too (which means you may 
switch away from upstream defaults a lot). 
An example where this may lead to trouble: you end up with sys-devel/gcc[-
cxx], i.e. a compiler that cannot translate C++.

* The dependencies on specific Python or Ruby versions are controlled via 
useflags. Basically, if Python package X needs Python package Y, both have to 
be installed for the same Python variant for things to work. If you disable 
all useflags via "-*", you basically disable support for all variants. Bang.

* Similar for multilib installations.

Volker is correct.

The reason you will break your system is that you do not have enough
knowledge to know what to put back, and you don't know how to read the
error messages and know what they mean.

Here's what portage does NOT do:

Tell you that flag x is missing and this will cause issues a, b and c,
then give you exact instructions how to make it better.


Here's what portage DOES do:

Give you some weird error message with the word "backtrack" in it, or
messages like "no parents that could not be satisfied by other packages
in slot" or something about blockers in flashing red blink text, or it
might even just say nothing giving the impression everything succeeded.
And then your computer explodes.


Still wanna try USE="-*" ?

In such cases I tend to suggest installing ufed. 'tis a UI for setting use
flags. Not only does it show you the description of every flag and whether
it's local (used by only one or a few programs). It also shows you if it is
enabled (+ sign), disabled (- sign) or not touched (empty) and whether that
setting comes from the profile (parens) or your own setup (brackets).

late to the conversation but no one else has mentioned, you might want
to take advantage of the newer way of doing use flags.
i.e. do not put them all in /etc/portage/make.conf
take advantage of the /etc/portage/package.use/  (you might need to
mkdir this)
in there you can put a single file per package requirements.

i.e. you try to emerge etherape, and it tells you that libgnomecanvas
requires use of glade
so cat the requirement into a file named by what requires it

$ cat /etc/portage/package.use/etherape
>=gnome-base/libgnomecanvas-2.30.3 glade

this also works for package.keywords etc

this means that you can more easily keep track of which use flags are
for which programs:
$ ls /etc/portage/package.use/
chromium   efl          freemind        teamviewer   transmission
compiz     etherape     gvfs            terminator   vinagre
darktable  filemangler  networkmanager  thunar       virtualbox
dvdrip     firefox      stellarium      thunderbird  wpa_supplicant
