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. Alec

I am not trying to have severe control, I just want to expand my knowledge!
thanks.
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.

Re: [gentoo-user] USE flags handling
Portage profiles set some default USE flags, then some ebuilds also set defaults. Using USE=-* disables all of these. You can see the defaults 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? 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. 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.

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.

Re: [gentoo-user] USE flags handling
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.

I don't think it's a bug, it's more like a difference in interpretation. From the man page: --buildpkgonly (-B) Creates binary packages for all ebuilds processed without actually merging the packages. This comes with the caveat that all build-time dependencies must already be emerged on the system. --keep-going [ y | n ] Continue as much as possible after an error. When an error occurs, dependencies are recalculated for remaining pack‐ ages and any with unsatisfied dependencies are automati‐ cally dropped. Also see the related --skipfirst option. So, decisions about --buildpkgonly are made at the start of an emerge and --keep-going kicks in only when an error occurs at the end, and the former must have higher precedence than the latter. It doesn't make sense to expect portage to change it's behaviour about it's initial decisions just because you also have an entirely unrelated option set that is only a convenience in the event of a build failure. That seems to me too much of an unexpected side effect -- Alan McKinnon alan.mckin...@gmail.com

One slight problem, it ignores slotted packages. I realise this is not a
big issue as you are simply trying to get the big packages built in
advance, If you drop the --columns and replace the awk call with
sed 's/.*\] \(\S*\).*/=\1/'
you will get properly versioned atoms.
Or you could try --keep-going as suggested by Marc - I've no idea whether
that will play nicely with --buildpkgonly.
Either way, it's an excellent idea and one for the GMN tips thread.

[gentoo-user] USE-flags and CFLAGS of stage3?
Does anyone know what are the USE-flags and CFLAGS used for the current stage3?
The reason I'm asking is that I keep finding myself having to upgrade
glibc and gcc when I install a new Gentoo system, so I want to save
some time by doing a 'pre-upgrade' of glibc, gcc, and libtool. Then
I'm going to tarball the result in a custom stage3 ('stage3.1', if you
wish), and use this as the starting point for future Gentoo boxen.

Thank you for the insight, Alan. I am just getting to the point of
understanding this. As a non -developer/programmer I have been at a loss to
understand these basic points about USE flags. Over time, they begin to
make sense. Your pointer about the ebuilds is extremely valuable.
Maybe it's just me, in my cluelessness? Some flags have not been obvious to
me; others have been ambiguous, at least to me. Maybe digging for all this
is what makes Gentoo such an excellent experience. On the other hand, a
little more clarity would not hurt, IMHO. Beggars can't be choicy, but is
it really not possible to provide a slightly clearer explanation of what a
USE flag does? I'd better shut up.

AFAIK the only references to what the flags mean
is /usr/portage/profiles/use.desc. To find out more, read the ebuild to
see/divine what the developer has in mind with that flag. For instance,
kdebase-3.5.5-r3 has amongst others the following:
DEPEND=arts? ( ~kde-base/arts-${PV} )
=media-libs/freetype-2
media-libs/fontconfig
pam? ( kde-base/kdebase-pam )
=dev-libs/cyrus-sasl-2
ldap? ( =net-nds/openldap-2 )
cups? ( net-print/cups )
...
So you would have to look into those various optional packages, find out
what they are, then look into kdebase a bit deeper and find what it
does with those optional packages. For example, the 'ldap' flag causes
kdebase to be built against net-nds/openldap.
The point is that it's simply not possible to give detailed info about
USE flags most of the time, and some intense RTFCing and research is
involved

They are just another one of those things that are the way they are
because someone made them that way, and the existing descriptions of
USE flags are meant to be meaningful in one sentence. Returning to the
kdebase example:
[snip]
DEPEND=arts? ( ~kde-base/arts-${PV} )
=media-libs/freetype-2
media-libs/fontconfig
pam? ( kde-base/kdebase-pam )
=dev-libs/cyrus-sasl-2
ldap? ( =net-nds/openldap-2 )
cups? ( net-print/cups )
There are 3 flags there: pam, ldap and cups and the only thing anyone
can tell you about them is that they respectively enable pam, ldap and
cups support inside kdebase. As to what that means, you will have to
look at the kdebase documentation to find out what that package does
with pam.
xscreensavers also has a pam USE flag, and the way it uses pam might be
essentially the same as what kdebase does with it. Or it might not. It
all depends on how xscreensavers was written, and this is outside
gentoo's control.
I understand you would like more clarity and I get the kind of list you
would like to have. I want you to grasp though that this is not really
possible in any thorough way. A detailed explanation of what the USE
flags means inside each ebuild that uses it is something you might
suggest, but I'll bet money that you will be shot down in flames for
suggesting it. It will be a lot of extra work on top of a lot of
existing work, for precious little benefit as the info is usually
documented elsewhere in the package itself. And we are supposed to all
know how to RTFM right?

seems :-)

[gentoo-user] USE flags information resource
After about a year of using Gentoo, I am very pleased. Not being a programmer, I do tend to spend alot of time on that learning curve. It has become more and more apparent in the past couple of months that USE flags really *are* as fantastic as they are cracked up to be, in at least one way---they enable the tuning of each package within whatever parameters are available for that package. Nothing even close to that is available on other distros I have used (well, slackware had at least emacs-nox, I guess). Like my 4 year old son, I learn about the system by pounding on keys. I have always tended to tank up on caffeine before an install session, and install everything I can get my hands on. Some of them wouldn't work, but that was just, as I understood, the law of probability in action. I have been getting wiser and wiser at fixing broken merges, and often it has required to take some time, read the output, and reinstall some dependency with a USE flag enabled or disabled. I have been learning to take it slow in installing packages, check out the situation before doing the actual merge itself. This is just as important as the docs said, despite my hurly burly approach. I have had it in mind to post about this, but now I think I have a suggestion that may be useful: I wiki about USE flags would be extremely useful. Am I the only one, or are newbies the only ones who encounter USE flags with cryptic significance? The descriptions from euse, profuse, etc., are a bit of a help alot of the time; however, some use flags would bear some serious explanation! Is something now available that would provide this functionality?

[gentoo-user] USE flags question
Am I correct in thinking that USE flags in /etc/portage/profiles/use.desc are global flags and should be placed in /etc/make.conf whereas those in use.local.desc are only local flags and should only be placed in /etc/portage/package.use with the appropriate package?

It doesn't really matter. Where you should put them depends on how you want them to take effect. A flag that only affects one package will affect that one package regardless of whether it's in make.conf or package.use, so I prefer to put it in make.conf for clarity, especially in the --info context. On the other hand, flags that many people consider to be global (apache2, mysql, php, etc) I only enable for one or two specific packages, as needed. -- gentoo-user@gentoo.org mailing list

Tony To tell the truth, you can put either kind of use flag in either file. The difference is what you want to apply the flag to. If you want only a single package to have a global use flag set differently from the rest of the system, you put it in package.use. If you see a local flag that might later be used by other packages, or is used by multiple packages, you might want to put it in make.conf. -- gentoo-user@gentoo.org mailing list

For some reason the doc would not compile for hal. I wanted the docs for everything else though so putting -doc in the USE line in make.conf would remove the docs for everything, not just hal. I put this in /etc/portage/package.use: sys-apps/hal-doc That way it would not enable the doc part for hal but would leave it for everything else. You could reverse that function if you wanted to. You could disable doc for everything in make.conf then make a exception in package.use for hal, if you can get it to compile with no errors. Did that help any?

Local flags may be defined for more than one packages, with different meanings, whereas global flags tend to be more consistent. So it may be safer to put local flags in package.use to avoid the situation where the same flag with a different meaning is added to another package you use. -- Neil Bothwick TROI : What am I sensing??

No. In portage.use, you'd write (for example): media-video/mplayer musepack And then mplayer will be compiled with musepack support. If the necessary libraries/files for musepack are not yet present, they'll be installed automatically. emerge -vpt mplayer will clearly show that. Or, do I have that wrong? Automagically mplayer will see 'media-sound/lame-3.96.1' and incorporate lame into mplayer? If a package requires a different package, that different package is automatically pulled. Or, is lame installed seperately? Maybe. I don't know. But, I don't seem to have xmms installed, while I do have totem, so, I'm not totally understanding the significance of the above list. Hm? I don't understand that. USE flags set options. So, if a package has support for xmms, USE=xmms will make the package use xmms; ie. it'll be compiled with appropriate flags.

They would both recursively install lame, with lame known to both mplayer and the second app? Lame would only be emerged one time. Use flags determine one or both of two things: 1) which packages and of what versions should be present on the system to support the desired new/updated package, and 2) what options (make config, I think) should be used when compiling those packages. You are concentrating on number one, above. For example, emerging PHP with the cgi use flag creates the PHP CGI binary, while the apache2 flag will create the (forget the correct name) in-process library for Apache2. Similarly, if MySQL is aleady installed, but the -mysql flag is used, the PHP libraries for communicating with MySQL will not be created. Having done that, subsequently emerging phpmysql will not re-emerge Apache OR PHP, even though they are both requirements. However, I don't know what would actually happen, since the scenario above would have you with PHP on your system but without its being able to access MySQL...
