Doc generation pulls in many otherwise unneccesary dependencies in order to generate the documentation, and is known to cause many circular dependencies due to eg. documentation generating software needing itself to generate its own documentation. A general piece of advice: You might not want to set a long string of USE flags globally immediately in your first install, rather pick a profile and adjust flags when/if the defaults don't suit you.

openrc-force
If you are unfamiliar with gentoo's profiles, most (all the
handbook-documented) profiles inherit the base profile which
contains this file, which means this mask is in effect on most systems.
None of the other profiles currently disable this use-mask. emerge's
output indicates to you that this use flag is masked by enclosing it in
parenthesis, check the documentation for the --verbose switch in
emerge(1)[1].
Use-flag masks from the selected profile (and the opposite, force)
override the use-flag settings normally made by users in make.conf and
package.use. User modifications to the profile should be made
in /etc/portage/profile/, see portage(5)[2].
To un-mask the openrc use flag, you can create the
file /etc/portage/profile/use.mask with this line:
-openrc-force

You might be able to use the ebuild stand-alone by also copying the
relevant eclasses from whereever you got the ebuild into your local
overlay (where I presume you put the ebuild?). However, from previous
experience with the Progress overlay, you might want to use the entire

The ebuild is from the ezod overlay. I am trying to use the ROS
related packages like wstool, rosdep. etc. They all seem to use this
EAPI. I thought that using this overlay would be easier than using
pip but apparently it's not is it?
Installing python packages though pip (without using virtualenv or such)
is not generally a great idea on gentoo, in particular many
not-quite-standard packages seem to get confused by gentoo's
python-exec and overwrite it, or automagically pull in some other
dependency (typically setuptools) which is already installed, and
clobber files that have been especially patched for gentoo with
non-working vanilla versions.
Looking at [1], it appears the overlay maintainer just recently (last 4
commits) moved to use the 4-python eapi. From having made this mistake
myself in the past, I would guess he added the eclasses to his overlay
locally and forgot to add them to git. Alternatively, an updated
layout.conf might not have been commited.
You could try creating an eclass/ folder in the overlay and put
distutils.eclass and python.eclass from the Progress overlay[2] in
there.
I notice that the ebuilds in question seem to be quite cookie-cutter
(as python ebuilds generally are, bless them!). Functionally migrating
them to the gentoo python eclasses should not be a large job.
Change `EAPI=4-python` to `EAPI=5`,
change `inherit distutils` to `inherit distutils-r1`,
add a line `PYTHON_COMPAT=( python2_7 python3_3 )` (or as appropriate).
Slightly more involved (but not strictly necessary to make it work
locally) is to fix up the dependencies. In particular, python library
dependencies should specify the required python implementation, like so:
DEPEND=dev-python/pyyaml[${PYTHON_USEDEP}]
See the wiki[3] for more information on python ebuilds :-)
I CC the ezod overlay maintainer on this email to inform about the issue
and facilitate a proper fix, either in documentation form or overlay
code.

Can anyone clarify the linguistics involved here? The scope of UEFI is somewhat greater than that of traditional BIOSes. Both do various hardware initialization and such, but UEFIs (can) have a number of additional features, including more flexibility in what it can launch from where (eg. network booting without iPXE) and even an interactive shell.

I have a box running Duet, which is an UEFI implementation that can be launched by (eg.) the extlinux boot loader on a legacy BIOS system. Once Duet is launched, the system is mostly indistinguishable from a native UEFI system that has booted into it's UEFI firmware. From here, Duet can let the user go through menus to select an EFI executable to launch (a EFI-stub enabled kernel or some sort of boot loader), or it can automatically launch something based on existing configuration. 1: https://en.wikipedia.org/wiki/UEFI#Features -- eroen signature.asc Description: PGP signature

I'm planing on installing Gentoo on a few systems and I was wondering to save bandwidth, i could install portage to the other Gentoo installs from my system instead downloading from mirrors? Thanks in advance! Setting up a local rsync mirror for a portage tree is fairly simple, you share the working tree at /usr/portage on a local server to the network and make sure the server is up-to-date before syncing other clients to it. This is documented in [1]. After setting up the mirror, you only need to sync-uri in /etc/portage/repos.conf on the other (local) clients. See portage(5)[2], section 'repos.conf' and make.conf(5)[3], section 'SYNC' for details on client configuration. Please *do* read those sections, as much of the information on the wiki regarding the SYNC variable is outdated. For sharing distfiles between hosts, a http server sharing the distfiles folder and prepending the server's uri to GENTOO_MIRRORS in make.conf[3] might be sufficient for your needs. If the installs are not homogenous, you can even set up http servers on all of them, and add all the other local hosts to GENTOO_MIRRORS. You might want to skim through the FEATURES section in make.conf(5)[3] for using local distfiles mirrors, as some of them can improve the usefulness of the mirror significantly. NFS is another possibility for both portage tree and distfiles and can reduce total disk space needs, but it incurs significant network latency which is especially noticeable for portage trees. I use it myself for virtual machines, but would not suggest it for use over a physical network. Also note that portage has PORTAGE_RO_DISTDIRS[3] as an alternative to GENTOO_MIRRORS for eg. read-only *mounted* network shares which may provide some extra flexibility. 1: https://wiki.gentoo.org/wiki/Project:Infrastructure/Rsync#Setting_up_your_own_local_rsync_mirror 2: https://dev.gentoo.org/~zmedico/portage/doc/man/portage.5.html 3: https://dev.gentoo.org/~zmedico/portage/doc/man/make.conf.5.html -- eroen signature.asc Description: PGP signature

Afaik there is no configuration-only way to do this, but you can

Thanks eroen, I tested it and it looks like it works.
One caveat,
=cat/pkg-3.10* also matches cat/pkg-3.107.1,
I guess that kernel versions = 3.100 are going to be in the tree, if
ever, probably in about a decade from now :P
which could become an
issue if you wanted, say, the 3.2 series.
Why would that be a problem?
In the ebuild, you specified the value
RDEPEND==sys-kernel/gentoo-sources-${PV}*
I think you got it, but then I confused you with a poorly chosen
example. The problem I referred to; if you try this exact method to
follow the 3.2.x kernels, you will switch to 3.20.0 when that comes
around. Similarly, it does not currently work with 3.1.x, and could
eventually (in a very long time, like you commented :P ) break for
other versions.
It would be nice to have a better way to accomplish this, perhaps
with some sort of world file variant supporting version ranges. That
could also be more intuitive and less prone to unintended consequences
(especially in the face of SLOTs) than package.mask-ing newer versions
to keep an old version of something around.

You don't say when your baseline was, but the complexity of resolving the package tree has increased quite a bit over the last year due to new features like automatic rebuilds of consumers after library updates. Another somewhat common cause of sudden slowdowns is how portage resolves conflicts (like packageA requiring an old version of libraryB), which is rather time-consuming. You can try adding --backtrack=0 to the emerge command to make it stop and print an error message when encountering a conflict rather than look for a solution. Then you can 'help' out by manually resolving any conflicts by adding package versions to /etc/portage/package.mask .

The most significant difference is that cairo might stop working if lzo is removed after cairo was built*. To resolve this, the Gentoo maintainer recently added lzo to the dependencies to make sure lzo is not removed. If you rebuild cairo after installing lzo, some obscure feature might be enabled, but the maintainer seems to think this is not significant, and did not increase the revision number to force a rebuild everywhere. http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/x11-libs/cairo/cairo-1.12.14-r4.ebuild?r1=1.12r2=1.13 * In most cases, that's prevented by the (now default-on) preserve-libs FEATURE in portage. Non-default setups aren't necessarily as lucky. $ equery d makedepend * These packages depend on makedepend: app-cdr/cdrtools-3.01_alpha17 (x11-misc/makedepend) http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/app-cdr/cdrtools/cdrtools-3.01_alpha17.ebuild?r1=1.13r2=1.14 A similar change (though no bug :-( ), except makedepend is a build-time-only dependency, and not strictly required after cdrtools is built. I will not venture to guess what the consequences of building cdrtools without makedepend installed are, but since you somehow got it installed at some point, there is either a fallback of some sort, or you had it installed for other reasons. Whether this build-time dependency (DEPEND) change causes makedepend to be installed after the fact is governed by the --with-bdeps switch to emerge, check the man page for details. But cairo was last emerged 16 days ago and cdrtools last September, so why have these dependencies suddenly appeared today? Portage has been at 2.2.7 since last year too. Emerge --info doesn't mention lzo. By default, in order to let maintainers fix issues, portage calculates what to install based on the *current* package ebuilds, rather than the ebuild at the time a package was installed. While this can be disabled by the user, maintainers will expect it to work, so best not ;-) I can't think of anything else that might have changed, unless new dependencies have been shoved into the ebuilds. Does that sort of thing happen in a well run family? -- eroen signature.asc Description: PGP signature

For instance, to capture one frame and store it as a png image (using libav's avconv, ffmpeg would be similar), you can use avconv -f video4linux2 -i /dev/video0 testframe.png mplayer (and its descendants) also play well with v4l, to directly display the webcam's input you can use mplayer -tv driver=v4l2:device=/dev/video0 tv:// (The -tv switch and its argument are probably redundant as the default detection is very good.) -- eroen signature.asc Description: PGP signature

Sharing a portage tree (the files in /usr/portage) is perfectly safe, as this is identical for basic gentoo systems (prefix and similar are ...different. Best not go there ;-). However, the eix database is not portable between different systems. I do not have an exhaustive list of what settings cause incompatibility, but at least different ARCH (amd64 or arm) will cause issues since different packages are available to each. Especially with the ARM I need to sync once a day, since I have to limit the amount of software to be recompiled/updated after each sync since the ARM is not *that* fast (for example a kernel compilation take ~8h). While that is not strictly enforced, I myself run an rsync server locally, mostly to ensure that different systems have identical trees, thus preserving my sanity. Instructions for setting up a local rsync server can be found here: https://wiki.gentoo.org/wiki/Project:Infrastructure/Rsync To make a client (the arm box) sync from the local server, just change the sync-uri variable in /etc/portage/repos.conf/gentoo.conf and the SYNC variable (if present) in make.conf . You could even share a portage tree over nfs or similar, which I sometimes do for VMs. Depending on your (networking and storage) hardware, that might even work out favourably performance-wise. You could also generate a squashfs image on the desktop and transfer that to and mount it on the arm box (over http or something using a short shell script), if, say, the arm box is limited on storage space. A squashfs of the gentoo tree is about 70MB. -- eroen signature.asc Description: PGP signature

[gentoo-user] Re: @preserved-rebuild gone in a loop

This will cause the portage to drop the library-references in question and add new ones. So, this should do the trick: emerge -C app-antivirus/avast4workstation emerge -1 app-antivirus/avast4workstation This will make the message from portage and the old library version go away, yes. It will also cause the program that used the library (/opt/avast4workstation/bin/avastgui in OP's case) crash when you try to run it, due to the old library version not being installed. The correct solution to this is to add the specific (old) version of the library to the dependencies (in the ebuild) of the (binary) package that uses it. This will prevent an upgrade that uninstalls the old library version. Sometimes the maintainer of the library will add a slotted version of it, so that non-binary users of it do not have to use the outdated version. If the binary package is not an ebuild, you can manually add the newer library version to package.mask, or make sure that the slot for the older version is installed if the library is slotted. Better yet (in all cases), get a more recent version of the binary package that is built against the newer version of the library. Complain to the vendor if none is available :-) The preserve-libs feature in portage is intended to let things keep on working short-term for source-distributed packages. In that case, the currently installed program is linked against the old library version, and when the program is rebuilt (with @preserved-rebuild) it will be linked against the newer version. -- eroen signature.asc Description: PGP signature

I got a cheap (bw) HP LaserJet p1005 half a decade ago. It works well with the drivers from http://foo2zjs.rkkda.com/ , which lets me avoid using the bloated hplip mess (I tried that when I got the printer, it didn't work with network printing and required a running X session). It looks like the printer you mentioned only works with hplip. If hplip is acceptable to you, that is great, otherwise I would suggest looking for a different model that is either natively supported by cups or supported by the foo2X drivers or other similarly non-intrusive drivers. -- eroen signature.asc Description: PGP signature
[gentoo-user] Re: Any good way to pick global USE flag alternatives?
On Mon, 09 Dec 2013 08:25:19 +0200 Nikos Chantziaras rea...@gmail.com wrote: There are some global USE flags that allow users to pick alternative methods of implementing the same thing. For example, packages that offer a GUI might do so through the qt or gtk USE flag. Or audio support, where you can choose alsa or pulseaudio. Now, if I wanted to, for example, always choose PulseAudio support instead of ALSA and a Qt GUI instead of a Gtk+ one, one would think that I could just do: USE=pulseaudio qt -alsa -gtk in my make.conf. But, that doesn't work. That's because some packages don't offer an alternative at all. Some package might only support ALSA for audio, and disabling that would lead to the package not offering any audio output at all. Or it might only offer a Gtk+ GUI, not a Qt one, and disabling the gtk flag will make the package not building its GUI component at all. So what's needed here, is a way to tell Portage to only disable a global USE flag for packages that also offer another one, specified by the user. Like this pseudo make.conf syntax: USE=pulseaudio pulseaudio?(-alsa) qt qt?(-gtk) Is something like this already possible? Right now, the only way to painstakingly go through every single package that comes up on an 'USE=use_flags_here emerge -pDN @world' and insert them individually into package.use. There should be a proper way of doing this. I like this idea, I think it could be especially useful in the context of PYTHON_SINGLE_TARGET. I'm not sure I like all the details in the suggestion, though. In particular, the flags you mention have widely varying meaning throughout the tree, for example mkvtoolnix has wxwidgets and qt4 use flags that enable independent and completely different things. Perhaps it would be better to implement this as a new analogue to USE_EXPAND always expands to the first item in the user configuration that is also in IUSE for the package? This would then exclusively be used for pick one of these options style settings, like the gui of *some* packages, TLS implemetation, PYTHON_SINGLE_TARGET and so on. I think this could be preferable to the many packages that currently just arbitrarily picks one choice when two mutually exclusive flags are enabled. It might be necessary to expand this with some form of light masking for ebuilds that want to *strongly* suggest one choice over another. Example: User sets (in make.conf): TLS_IMPL_PREF=openssl gnutls Ebuild with IUSE=tls_impl_pref_gnutls tls_impl_pref_openssl sees tls_impl_pref_gnutls as disabled and tls_impl_pref_openssl as enabled. Ebuild with IUSE=tls_impl_pref_gnutls sees tls_impl_pref_gnutls as enabled. -- eroen signature.asc Description: PGP signature
