[gentoo-user] Question on my USE choiche
Hi all, my first post to Gentoo lists! I already installed Gentoo some time ago, and want to restart now from zero, to see how much I've learnt in the meantime.

Hi all,

I already installed Gentoo some time ago, and want to restart
now from zero, to see how much I've learnt in the meantime.
My biggest doubt has always been which USE flags to use.
I do a lot of home work with multimedia stuff (audio, video...)
and need also a lot of scientific and programming stuff.
Tiny spare time is used to study networking and such.
So I put together a list of flags, that at first sight looks
huge; here it is:

First question: is it a good starting point or is it
excessive/unneccessary?
That's a little excessive. For example, you have cups twice.
The thing is, useflags are now cascading, and you don't seem to use that
feature very much. For example, truetype-fonts, type1-fonts are included in
your make.default. Hence, they are already present opn your system, there is
no need to specify them twice.
Moreover, some of the usflags you specify are definitely local useflags. For
example, libg++ affects only postgresql. It should not be in your make.conf,
since it makes it very hard to read. (Moreover, libg++ is enabled by default
in the make.defaults).
You have a typo : aalibaccessibility .
You might want to avoid putting arts in your useflags, since arts is
definitely the worst thing that can happen to your sound system (No flamewar
intended, even the kde devs have decided to take it out of KDE4). However,
you'll need kdelibs to be compiled against it if you want to hear sounds in
kde (and I mean sounds generated by kde, not sounds from amarok...)
So, to sum up, what I would do is :
1) Put USE= and do an emerge --info to see which useflags are enabled by
default.
2) Ask myself the question : Do I really want *any* application running on my
computer to have feature foo. If the answer is no, the useflag should be
in /et/portage/package.use
3) Organise the useflags in make.conf by theme : For example
## System
USE=alsa mmx sse sse2
## Desktop environment :
USE=${USE} gnome kde kdeenablefinal
...
I find this more readable than a long USE=... list.
If I avoid putting things in does it mean that if I add them in
a second moment probably some of the installed stuff needs to be
recompiled?
If you add a useflag, there should not be any problem. However, the app will
make use of the new feature only if it has been recompiled.
If you remove a useflag, from a library for example, the apps linked to that
library can break. You'll need to recompile the apps.
Anyway, if you change your useflag one way or the other, you should :
1) emerge --newuse --ask --verbose world
2) revdep-rebuild
Thanks, Leo
Beware of automatic useflags :
- Portage 2.1 (stable)
Beware that those versions of portage have automatic useflags enabled. For
example, if you emerge mysql, the mysql uselfag will be turned on globally.
If you unmerge it, the useflag will be turned off (except if it is mentionned
in any of the config files).
- Portage 2.1 (unstable, but really, works very well) does not have that
kind of behaviour.
I hope this was clear enough,

If by restart from zero mean reinstall then that would be pretty pointless. There are easier ways to get to the same result. My biggest doubt has always been which USE flags to use. I do a lot of home work with multimedia stuff (audio, video...) and need also a lot of scientific and programming stuff. Tiny spare time is used to study networking and such. So I put together a list of flags, that at first sight looks huge; here it is: First of all it should be noted that use flags are for optional stuff only. If you put -X in your use flags apps that depend on X will still depend on X. Only apps that have optional dependency on X will stop depending on X (e.g. links). Further it should be noted that use flags really are your choice. Noone else can really you what you need. Still a (few) comments: USE= [...] imlib libg++ libwww mad mpeg -nptl pdflib spell pdflib has been removed in favor of pdf. truetype-fonts type1-fonts X xml aac aalibaccessibility acpi s/libacc/lib acc/ guile hal hardened icq idn iee1394 imagemagick imap inifile s/iee1394/ieee1394/ jabber jack java javascript joistick jpeg jpeg2k kde s/joistick/joystick/ wxwindows xine xinerama xml xml2 xmms xosd xpm xprint xv xvid xml2 is deprecated in favor of xml. [...] First question: is it a good starting point or is it excessive/unneccessary? A bit excessive, yes. :) You have both alsa and oss in your use flags. OSS is deprecated in favor of ALSA and hence if you have alsa enabled in your kernel you really shouldn't need optional oss. Also you have both arts and esd in your use flags both of which serve the same purpose (arts is for kde/esd is for gnome). They are sound daemons that allow several apps to use the sound device even if the sound driver allows only one app at the same time. Yet modern alsa drivers do allow multiple apps to use the sound device at the same time. So IMHO sound daemons are an unnecessary overhead. Therefore I would recommend alsa -arts -esd -oss. Is there a reason why you have -nptl in your use flags?? If not and if you do use a 2.6 kernel I recommend you enable it. It is the replacement of linuxthreads and it does perform better.. I actually have nptl nptlonly in mine.. Other than this I don't intend to comment any further on this. You really are the only one who can say what you need. You do have a lot of use flags enabled and some would say that it makes your system bloated.. But it really is up to you. If I avoid putting things in does it mean that if I add them in a second moment probably some of the installed stuff needs to be recompiled? Yes. Run 'emerge --newuse --deep --verbose --pretend' to see what use flags changed. It the changed flags with a * and a different color if they changed. -- Bo Andresen pgpQ2ClhhXi0B.pgp Description: PGP signature
