There was also another GUI with commands like on this screenshot:

to launch it. :-)

Rgds,



I just added it to fstab so that it mounts automatically.  If I am 
running some program that needs that much ram, I can always unmount it.  
If course, when knotify went wonky the other day and was using 14Gbs of 
ram, it didn't complain about tmpfs or anything.  It did get a bit slow 
until I killed it.  Don't have KDE running when you recompile some parts 
of it.  ;-)

[gentoo-user] dev-lang/cabal-install compilation fails

[wolf python london]

Hey list,

I want to use cabal-install in my Gentoo box , but fails :-.

it seems that cabal-install depends on mtl, so in the phase of
compiling mtl , it reports error .

Shouldn't you be rounding down, instead? That said, as long as the number
falls between 1.6*N and 1.8*N (see my previous post), nothing should blow
up. Well, not spectacularly, at least :-)

BTW, FYI, --load-average accepts non-integer values.

The explosion of information in this thread is going to make for a
*great* followup blog post. :)

Now I just wish there were a way to get Portage and Make to watch CPU
usage and raise or lower the load-average threshold depending on how
much CPU was going to 'sys', 'user' and 'wait'; Lower -l if a great
deal of time is spent in 'sys'; you're likely burning cycles in
context switches. Raise -l if a great deal of time is spent waiting on
I/O.

It'd also be helpful to be able to give keystone[1] packages and Make
recipes a more favorable NICE value than those less important, to
induce the scheduler to favor the important packages over
less-important packages when we've got more ready work than cores. I
don't think Make *can* have the smarts for that, but Portage could
conceivably do it for its own parallelization.

[1] Where many things depend on them, either directly or indirectly.
Getting these out of the way means more parallel-buildable packages
being available at the same time.

Just in case anyone wonders where the multiplier "1.6" comes from:

There had been a discussion somewhere (I forgot where exactly, sorry) about
load numbers. The final conclusion was that the ideal load number for
today's processors is 2*N, because with the out-of-order capability of
modern processors, two instructions can overlap in the pipeline, even
without hyperthreading.

Unfortunately, striving for 2*N will inadvertently result in short bursts
of > 2*N, and this potentially induce a stall, which will be very costly.
1.8*N gives a 10% margin for burst activities, while 1.6*N gives a 20%
margin.

Since emerging packages has a sudden increase in load when autoconfigure
finishes and make fires up all the parallel building, I figure 20% margin
will be better.

Of course, that's before @mikemol made me aware of MAKEOPTS -l, so I am now
tempted to raise the load-average to 1.8*N, letting make handle the bursts.

Rgds,

Most likely so. I am not aware of -l in MAKEOPTS before, so what I posted
was my workaround to prevent load explosion. Thanks to your very useful
tip, I now no longer have to worry about load explosion :-)

(I still like doing pre-fetchonly-ing, though. But now for a different main
reason :-)

As I noted, "-l" in MAKEOPTS takes care of the load explosion very nicely.

I did notice that, but it settles back down *very* quickly with the -l
parameter to make.

It'd be a combination of them.

EMERGE_DEFAULT_OPTS, for my 8-way system, would have been -j8 (I'll be
changing this to reflect portage's load-aware behavior).

MAKEOPTS would be -j16, -l10. (Which actually goes up to about 12 or
13 based on that N*1.6 behavior)

More looking here.  This is what I found with euse -i on my amd64 system:

[-  ] introspection
sys-fs/udev: Use dev-libs/gobject-introspection for introspection


but this is what emerge shows:

root@fireball / # emerge -pv udev

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R] sys-fs/udev-164-r2  USE="extras -build (-selinux) 
-test" 0 kB


Total: 1 package (1 reinstall), Size of downloads: 0 kB
root@fireball / #

So, I suspect it is enabled somewhere on a much lower level and not 
optional.  Then I emerge udev and used the find tool.  I found these 
little tidbits:


./configure --prefix=/usr --build=x86_64-pc-linux-gnu 
--host=x86_64-pc-linux-gnu --mandir=/usr/share/man 
--infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc 
--localstatedir=/var/lib --prefix=/usr --sysconfdir=/etc --sbindir=/sbin 
--libdir=/usr/lib64 --with-rootlibdir=/lib64 --libexecdir=/lib64/udev 
--enable-logging --enable-static --without-selinux --enable-extras 
--disable-introspection


gintrospection: no

So, seeing that it is disabled, maybe it is disabled now on a lower 
level and is no longer a option?  Notice the question mark.  This makes 
me wonder.  It still shows up with euse.  It appears disabled but also 
doesn't show up as a USE flag option for us mere mortals.  ;-)


More looking.  I find this:

[-  ] introspection
media-libs/gstreamer: Use dev-libs/gobject-introspection for
introspection

Then emerge  reports this:

root@fireball / # emerge -pv gstreamer

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R] media-libs/gstreamer-0.10.35  USE="introspection nls 
-test" 0 kB


Total: 1 package (1 reinstall), Size of downloads: 0 kB
root@fireball / #

So, it is enabled on this one but not udev.  The flag does exist and can 
be controlled, at least on some packages.


My thoughts.  Some packages it is disabled somewhere that overrides your 
settings.  Might be because it breaks something.  The packages where it 
is a option, then it sees your settings and applies them.  I'm as 
confused as you are on emerge --info tho.  If it helps any, I don't have 
the flag in my make.conf but it appears to be enabled for gstreamer but 
disabled for udev.  I think the devs are picking and choosing which 
packages can have the flag user controlled and not break something.


One last thing that I find interesting.  This is weird.

root@fireball / # USE="introspection" emerge -Na world

These are the packages that would be merged, in order:

Calculating dependencies... done!

Total: 0 packages, Size of downloads: 0 kB

Nothing to merge; would you like to auto-clean packages? [Yes/No] n

Quitting.

root@fireball / # USE="-introspection" emerge -Na world

These are the packages that would be merged, in order:

Calculating dependencies... done!

Total: 0 packages, Size of downloads: 0 kB

Nothing to merge; would you like to auto-clean packages? [Yes/No] n

root@fireball / #

It appears that the packages on my system are all controlled by 
something over my settings.  It does nothing when I enable or disable 
it.  Yet it is turned on for one package above and turned off for the 
other.  Scratch your head on that one for a while.

It would be nice if there were some way to mark particular packages 
that should never be compiled in parallel (like the trick for using a 
using a separate, non-tmpfs build directory for large packages). The 
"load-explosion" you describe is bad enough with regular packages but 
when firefox, xulrunner, chromium and libreoffice all decide to start

I have a hunch that the hypervisor had some effects. Most likely, another
VM in the same host has a high enough load that necessitates the Gentoo VM
to be shifted to another (physical) core, and this messes up the timing.

MAKEOPTS=-j3 always succeeds, though. So I'm disinclined to delve deeper
into the issue.

Make sure that make supports non-integer values for -l, though.

Yes, sometimes that would happen if at the beginning there are
network-bound ebuilds all downloading their respective distfiles. The load
stays low until they all start ./configure-ing roughly at the same time.
Then all hell breaks loose.

I successfully mitigate such "load-explosion" by doing a --fetchonly step
first, and keeping MAKEOPTS at low -j (which, in my case, is actually
required).

Just to add more info: I use USE=graphite (with some CFLAGS, uh,
'enhancements') with gcc-4.5.3. IIRC, I could push MAKEOPTS up to -j5 (and
even more, but I ran out of cores) when I was still using gcc-4.4.x and no
USE=graphite.

Won't file a bug report, though. I have a feeling that my bug report re:
emerge failure will be marked WONTFIX thanks to the 'ricer special' CFLAGS

Yeah, could it be part of your profile? That's up in /etc so it could be

I'm not sure if any of those are GUI tho.

Maybe whatever distro you were using sort of played a name game with the

something else that had a GUI and was a front end for it.

Haven't done a depclean.  This is a reasonable new computer.  Haven't
used ImageMagick in quite a while (way before I got this new computer)
and granted, it wasn't a gui that automatically got added to your kmenu,
but I created an icon for and for the command, I used
/usr/bin/imagemagick.  I recall at one point that if I used the command
imagemagick, it would launch some other interface (can't remember which
one) and I had to create a symlink named magick which linked to
/usr/bin/imagemagick.  I have tons of graphics that I resized and
converted to png from jpegs, but unfortunately, the don't say that I
used imagemagick to alter them.

Two days wasted and I'm out of ideas.

Anyone understand the details of emerge --info or what I can do to

I searched the -dev mailing list and only found references to the flag

I would do a emerge -pv  and see if it shows

Oh, yes, it was!  :-)  There used to be a command in /usr/bin named
imagemagick and if you launched it, it brought up an interface with
menus/buttons that you could click on.  Granted, I haven't used it in
quite a while.  However, I used to use it all the time to scale graphics
when I was writing the handbook for krecipes and convert images from
jpeg to png.

The problem I found with that is the ebuilds load the system lightly to
start with, before they enter the compile phase, to portage starts dozens
of parallel ebuilds, then the system gets completely bogged down when
they start compiling.

Good post Michael. Thanks.

I want to verify that in make.conf this is indeed MAKEOPTS we are

MAKEOPTS="-j13 -l7"

or something in that range for a full blown emerge -e @world?

You should also look into this setting if you want to let portage run in 
the background:


PORTAGE_NICENESS=5

I have a 4 core system and run this:

MAKEOPTS="-j16 -l10"
EMERGE_DEFAULT_OPTS="-j8 "

I can't even tell portage is running.  Heck, I even watch videos and 
such.  No problems with slowdown at all.


Oh, the -l10 is sort of new.  The -j16 is changing a bit over time.  
Trying to test speed to see what is fastest.  So far, no compile race 
problems either.

A GUI interface specifically for imagemagick is news to me;
imagemagick has always been a cli program. I don't see any reference
to a GUI among its USE flags, either. Perhaps you were using some
other program which acted as a front-end? Have you done a --depclean
which may have removed that?

Incidentally, if you want to retain a package, you really should
select it for your @world set; otherwise, a depclean could pull it out
from under you.

ImageMagick has no gui-frontend and it never had. It's a library for image 
manipulation and a collection of CLI-programs for the same task.
I have no idea what you used before, but it wasn't part of ImageMagick.

Thanks for the comments.  I did the changes suggested in the bug report
(downgrade net-tools or specify USE=old-output).  This changed the
behavior, but it was far from perfect.

The next morning, however, after no hardware/software changes but after
our thanksgiving guests (plus their laptops, phones, and ipads) left,
wicd is working pretty well on both affected machines.  I was nowhere near
the 50 dhcp connection limit, but perhaps the extra radio transmissions
were hurting.  Anyway now one machine has the downgraded net-tools, the
other USE=old-output and both seem to work.

This was definitely not fun.  Now for a really scary thought.  I just
let portage put gnome 3 on my "extra" laptop.  That machine has a fresh
fairly minimalistic desktop/gnome install.  Light testing shows gnome-3
works as advertised.  Do I dare put it on my real laptop?  I am tempted
to wait until intersession so as not to hinder preparing for my
lectures; but I worry about letting a system go 1 month without updates.

I have something like 10 USB drives here at home. 9 of those drives
works perfectly in 5 machines in the house. 1 drive works when
attached to 4 of the machines but produces a similar error when
attached to my most expensive i7-980x machine.

I've never determined what causes it and have sort of decided it's
just some weird incompatibility...

This post

http://permalink.gmane.org/gmane.linux.usb.general/48758

implies possible hardware errors (you seem to have protocol errors on
the USB bus).

Before proceeding further, I'd try a few more tests to narrow down the
circumstances that produce the errors.

What results do you get if you plug the drives into different USB
controllers/ports on the gentoo system?

Can you test if they work with a different kernel version (higher and
lower than the current one in use)?

What kind of drives are these? Are you plugging USB3 drives into USB2
ports for example?

If you are really lucky you might have free space on a drive you can
run mkfs.vfat on and see if that works.

The results of these simple tests stand a good chance of pointing us in
the right direction for the next step.

It's EMERGE_DEFAULT_OPTS in make.conf. See man make.conf.

In my barebones 177-package state, I didn't get any build failures
from parallel building, either via emerge -j or make -j. I did get one
failure when I went to install X that worked fine on the second
attempt.

Parallel operations are finicky things; if you don't define the
relationships correctly, you can have things work fine most of the
time, and then a race condition between one make recipe and another
(or perhaps between one ebuild and another; a revdep-rebuild afterward
might not be a bad CYA) causes one thing to fail, just this one time.

My day job is C++ on Windows[1], and we do a *lot* with multithreaded
code. Race conditions are a PITA; you might not be able to reproduce a
race-induced failure on any of the workstations or test systems you
have, but then have it crop up consistently on a customer's system.
The same principles can and will apply with things like parallel make
and parallel emerge. I've even seen it happen in VS2005 and VS2008
parallel builds.

FWIW, I've been running with MAKEOPTS=-j10 on my Phenom 9650 for over
a year. It's very rare that something breaks due to the parallel
build. I think it's happened perhaps three times, and each time was
resolvable with a retry. YMMV, of course; race conditions are finicky.

Sweet; I didn't know about Portage's --load-average; I'll definitely
switch to that instead of -j. Load-driven make plus load-driven
portage should work beautifully on my system.

I'll steal your 1.6 factor, and give:
MAKEOPTS=-j <2*N> -l <1.6*N)
PORTAGE_DEFAULT_OPTS="--jobs --load-average<1.6*N>"
a try.

How does that interact with distcc, by the way? I've got two of these
octo-core Xeon boxes, and I've still got my Phenom 9650--distcc on my
home network should become very, very nice. And this box is consuming
255W at the wall with monitor off, 326W with monitor on. That's not
bad. Though perhaps I should move to an apartment where heat isn't
free...

[gentoo-user] USB Drive Mount

[sean]

I have two 500GB USB drives that my Gentoo system here will not read. 
Both these drives are fat formatted.


The tail of DMESG, the entries actually go on for a long long time, has 
the following report for either of those two drives,

Both these fat formatted drives are easily read on several other systems 
running Windows or MAC OS X.


The Gentoo system will read small usb memory sticks up to 16 GB fat 
formatted.

The Gentoo system will also read a 750 GB NTFS drive without problems.

Is anyone able to point me in the direction to figure out why the fat 
usb drives will not be read by the Gentoo system?

[gentoo-user] ImageMagick

[Colleen Beamer]

Hi all,

I used to use ImageMagick to quickly resize images and convert from one
format to another (jpg to png, for example).  ImageMagick is installed
on my system (installed as requirement of something else), but I'm
darned if I can find an executable to run the program.  There used to be
one in /usr/bin on my old system.

Does anyone have any experience with this?

I had no problem getting portage, the tar ball, but it never appears

At any rate, I guess you are not maintaining things at the repo eh?

Last time I checked it was hardmasked. Now it's been confined into
oblivion, I hope.
It had a "little" problem in resolving the dependencies of a newly
introduced boot service that created a cycle and caused the boot process
to hang (almost) forever with rc_parallel=YES.

With 100% repeatability, mind you, which does raise same questions on
the amount of testing done before release. Yes, it's ~arch and
rc_parallel is explicitly marked "experimental", but it's not expected
to be completely and consistently broken, either.

If that sounds like I'm ranting, it's because I just spent about an hour
getting three machines affected by this problem back into working state.

If anyone still has it installed, it's time to sync and downgrade :)

In my case it is.  I am caching all of /usr/share/ into a cache working

experiment and it doesn't seem to perform very well, so you don't really

Here's my experience:

I always experience emerge failures on my Gentoo VMs if I use
MAKEOPTS=-j>3. Not all packages, but many. Including, IIRC, glibc and gcc.

This happens even if I make sure that there's just one emerge job being
done. And this happens even if I allocate more vCPUs than -j, on VMware and
XenServer alike.

I don't know where the 'blame' lies, but I've found myself standardizing on
MAKEOPTS=-j3, and PORTAGE_DEFAULT_OPTS="--jobs
--load-average=<1.6*num_of_vCPU>"

(Yes, no explicit number of jobs. The newer portages are smart enough to
keep starting new jobs until the load number is reached)

emerge -j will be useful if the packages being emerged are independent from

I've developed a pretty accurate rule for determining how much disk
space is required for building LO.  Just before you start the emerge,
do a "df" command.  Take the number for the filesystem where your

Hm. Honestly, I don't know that it's such a terrible default. IMO,
it'd be better if builds couldn't be slowed down by slow terminals,

Hi,

does anyone own a Plympus LS-5 or Olympus LS-11 mobile
digital audio recorder here?
Is it possible to access this device 
1) as a usb storage device for downloading the recordings
2) as usb audio device to be used a stereo usb mcirohone
?

Thank you very much in advance for any help!

[Vishnupradeep]

What is multilib and how can I use it?

Every AMD64 processor is able to run 32bit code as well as 64bit code.
However, when you have a 32bit application, you are unable to mix it with
64bit libraries or vice versa. You can, however, natively run 32bit
applications if all shared libraries it needs are available as 32bit
objects. You can choose whether you want multilib support or not by
selecting the according profile. The default is a multilib-enabled profile.

*Warning: *Currently you cannot switch from a no-multilib to a
multilib-enabled profile, so think over your decision twice before you use
the no-multilib profile.

It grabs the sources from wherever they are specified (SRC_URI) in the

I had the same issue after upgrading net-tools, wicd stoped working.
While googling for a solution I found a workaround: Use the "ioctl" backend 
instead of the "external" backend.
For me this workaround works.

I don't know if this can be useful for you, however: having a box with
debian, I read the debian ML, too. Two weeks ago (if I remember
correctly) gnome 3 landed in testing, resulting in many discussions.
Among these, I remember that a few people claimed that fallback mode
is only a temporary solution, and, sooner or later, it'll be removed.
I don't know if it's true or not, but maybe this information can be
valuable (or worth verification) for those that are going to run gnome
3 in fallback mode... FYI only.

Cheers,

Lorenzo

Albert, I cloned your hg repo and tried to build from it, but it fails
at downloading gentoo-sources.  Something about not being able to
resolve the kernel URLS.

I suspect it is a problem in the ebuild itself, but I was not able to
find where `portage' is on disc during that build.  I wanted to
attempt editing the ebuild but even with variable:
  REMOVE_PORTAGE_TREE NO
I never find a `portage' directory.

Once the build fails, their is no `portage' directory containing the
tree.

In virtual-appliance:

  find . -type d -name 'portage'
  ./vabuild/var/lib/portage
  ./vabuild/var/log/portage
  ./vabuild/var/cache/edb/dep/usr/portage
  ./vabuild/usr/lib/portage
  ./vabuild/usr/lib/portage/pym/portage

None of those contain the tree.

THAT is the reason why neither revdep-rebuild nor @preserved-rebuild

letting the dynamic linker handle it when the application is started.
There is no reasonable way for revdep-rebuild to find these issues.

The display is something emerge will show you if you've asked it to
build in parallel (which you did, by passing -j to emerge. That's
different from putting -j in MAKEOPTS.)

> I only want to compile one at a time -- much safer that way and it is
> doing that,

It's likely only doing that because there isn't anything it can
immediately build that doesn't have what it's *currently* working on
as a build dependency. I noted in my blog post that emerge's
parallelization has many of the same limitations as make's that's one
of the things I was talking about; there can be linchpin and keystone
packages which need to be built before many others. libc would be an
example. gcc is a frequent example.

> but now it displays all that load average and how many jobs,
> etc. -- any way to get rid of that display?

Forget the display; it sounds like you don't want emerge building in
parallel. In that event, don't pass "-j" to emerge. The display will
go away.

I'm making an educated guess. >.>

I figure that the optimal number of simultaneous CPU-consuming
processes is going to be the number of CPU cores, plus enough to keep
the CPU occupied while others are blocked on I/O. That's the same
reasoning that drives the selection of a -j number, really.

If I read make's man page correctly, -l acts as a threshold, choosing
not to spawn an additional child process if the system load average is
above a certain value Since system load is a count of actively running
and ready-to-run processes, you want it to be very close to your
number of logical cores[1].

Since it's going to be a spot decision for Make as to whether or not
to spawn another child (if it hits its limit, it's not going to check
again until after one of its children returns), there will be many
race cases where the load average is high when it looks, but some
other processes will return shortly afterward.[2] That means adding a
process or two for a fudge factor.

That's a lot of guess, though, and it still comes down to guess-and-check.

emerge -j8 @world # MAKEOPTS="-j16 -l10"

Was the first combination I tried. This completed in 89 minutes.

emerge -j8 @world # MAKEOPT="-j16 -l8"

Was the second. This took significantly longer.

I haven't tried higher than -l10; I needed this box to do be able to
do things, which meant installing more software. I've gone from 177
packages to 466.

[1] I don't have a hyperthreading system available, but I suspect that
this is also going to be true of logical cores; It's my understanding
that the overhead from overcommitting CPU comes primarily from context
switching between processors, and hyperthreading adds CPU hardware
specifically to reduce the need to context-switch in splitting
physical CPU resources between threads/processes. So while you'd lose
a little speed for an individual thread, you would gain it back in
aggregate over both threads.

[2] There would also be cases where the load average is low, such as
if a Make recipe calls for a significant bit of I/O before it consumes
a great deal of CPU, but a simple 7200rpm SATA disk appears to be
sufficiently fast that this case is less frequent.

I assumed that /dev/sda5 is large enough and has free space that is not
being used for logical volumes. The lvcreate -L 10G step creates a
logical volume of 10 GB size, the rest of the volume group (that is using
the physical volume /dev/sda5) is being unused. You can create other
logical volumes with lvcreate, or extend existing ones, until all of that
space is being used. Then, you need to make something smaller of course
(which can be done), or you can extend your volume group by another
partition. Which may be on the same drive, or even on another one.

Thanks for sharing!  How do you determine the optimum value for -l?

The 1G is taken from the free pool of unused extents. This assumes you
have free extents, if not, then you do need to free some up somwehere
else first.

Using LVM is a lot like using a SAN - don't allocate everything right
at the beginning, rather give each lv what it needs today and grow it
as space needs change. This way you always have free extents available
for use.

Of course, just using /dev/sda5 for /usr is simpler. But what if this
turns out to be too small? With so many partitions I would think this
is very likely to happen sooner or later. With LVM, all you'd have to
do is:

   lvresize -L +1G /dev/myvg/usr
   resize2fs /dev/myvg/usr

Here I do not understand from where this +1G is taken?  Don't you have

Nope.  Not if you have 1Gb of space that is not used yet.  Here is a 
example:


root@fireball / # vgdisplay
  --- Volume group ---
  VG Name   data
  System ID
  Formatlvm2
  Metadata Areas1
  Metadata Sequence No  9
  VG Access read/write
  VG Status resizable
  MAX LV0
  Cur LV1
  Open LV   1
  Max PV0
  Cur PV1
  Act PV1
  VG Size   698.63 GiB
  PE Size   4.00 MiB
  Total PE  178850
  Alloc PE / Size   102400 / 400.00 GiB
  Free  PE / Size   76450 / 298.63 GiB
  VG UUID   eNF7B0-3BDb-qe1W-5FTH-4Uah-wRe1-xD7Xa8

root@fireball / #

Right now there is 400Gbs of space used.  I have 298Gbs of free space.  
If I wanted to add some space to something, lvresize -L +1G /dev/to lv here> would get it added then just resize the file system.


That help?

Here I do not understand from where this +1G is taken?  Don't you have
to make something smaller by 1G first?
