It also looks like firefox caches the error:

   Thanks.  I'll probably be back with a bunch of questions.  As a matter

 ...omitting /usr/libexec/gcc/x86_64-pc-linux-gnu/4.8.3/cc1 -E -quiet -v -
 I presume.  So on the 64-bit host, I would go from...
 
 CFLAGS=-O2 -march=native -mfpmath=sse -fomit-frame-pointer -pipe -fno-

   Is that correct (assuming that's my output)?

The CFLAGS on the host won't be used so you don't need to change them. Now on 
the host create scripts with the exact full name of the compiler on the target 
and make distccd can find them (either put them on /usr/bin or make sure to add 
it's path to the PATH environment var for distccd, if you're using openrc I'm 
not sure if the init scripts allow it so you may have to start it manually or 
modify the scripts) and have them exec gcc with the -m32 switch. Make sure you 
have the same version of gcc selected on both boxes.

The command not found part is because /sbin and /usr/sbin and on gentoo it's 
not on your PATH env var by default.

I think it's supposed to be a security measure but really it provides no 
security whatsoever so I always add it to my path. After that you'll be able 
to shutdown if there's no other active sessions, otherwise you should be

 I should warn you against including all of those -mno-xxx flags. This
 has been known to break the build process for packages like chromium,
 which always wants to build with SSE4 support and toggles it off at
 runtime. Passing -mno-sse4.1 causes a build failure as it tries to use
 macros that are not defined.
 

Isn't it possible that removing it for all packages would cause a more subtle 
problem with another faulty ebuild (like a program crashing due to an illegal 
instruction)?

  Either run poweroff as the superuser, or if you're running Gnome, KDE,

  I'ld say Don't : it's contrary to the principles of Unix,
  which separate the roles of sysadmin (root) from those of ordinary users.
  
  To shut down, I first exit Fluxbox via its menu,
  then 'su' + root password, then alias 'down' = 'shutdown -h now'.
  That observes the proper roles + ceremonies (smile).
 
 Interesting. But as I said ealier, I can reboot the system when I am a user 
by Ctrl+Alt+Delete. The user can reboot the system, but can't shut down? 
Strange
  

Either /sbin/poweroff or /usr/sbin/poweroff will do it from a local session (if 
there's no other users logged in locally).

Like I said, /sbin is only on the search path for root by default on gentoo.

 This way Ctrl-Alt-Del calls power off instead of reboot.
 So to shutdown I just exit from Openbox and press Ctrl-Alt-Del.

Also sysvinit specific.
On systemd you need to copy /usr/lib/systemd/system/ctrl-alt-del.target to

 Hi List,
 
 For the last few weeks i was playing around with my newly acquired
 raspberry pi 2. While it was pretty easy to setup a working gentoo
 stage3 system i failed installing anything below the basic packages.
 Generally my idea was building the arm packages on any system and
 provide them as binary packages for other raspberry pi's (yeah, i
 already bought my second rpi :D)
 
 At first, my idea was to build all the packages directly on the rpi. (with
 /var/tmp  /usr/portage on a external harddisk). However, the compile
 times are worse than i expected so i abandoned the idea.
 
 Next i've played around with crossdev. It sort of worked, but i never
 could finish compiling xorg-server. (or basic system packages) Even
 though i've started over and over with different settings, there were
 always packages which failed to compile thus doesn't let me finish
 xorg-server. I might look into it some other day but now i just wanted
 something working.
 
 Now i'm playing with using qemu-arm [1][2] in order to compile the
 packages inside a chroot. This is - so far - the most promising method
 building packages, even though the compile times are worse than with
 crossdev, but still better than directly on the rpi.
 
 So far i finally could compile xorg-server and also updated the whole
 system, which, at this point, wasn't much anyway. My next goal was kde.
 I've compiled about half of all packages which are required for
 kdebase-meta, but now i'm stuck at kdelibs and i have no idea what's
 wrong.
 
 The problem:
 
 The problem is, the compile doesn't fail - it just hangs/stops. At some
 point (which seems to be random - it can stop anywhere between 1% and
 100% of the compile) the compile stops and does nothing. I've waited
 hours, but nothing happened.
 So far i tried lots of things, for example:
 * MAKEOPTS=-j1 and/or FEATURES=-sandbox
 * also tried without building binary packages (-buildpkg)
 * /var/tmp on tmpfs
 * using: ebuild /usr/portage/kde-base//kdelibsebuild compile
 * using python3.3 instead of default 2.7
 * moved it on a different system and tried building it there (again with
 many different settings)
 
 Nothing worked, even though the build moved until 100% two times (-_-)
 
 I have no idea what the problem is. Even qtwebkit, which took way longer
 to compile (about 3 hours) compiled on the first try. (which should
 exclude temperate and/or resource problems)
 I also don't think it's a problem with a use flag as the build stops
 anywhere - i couldn't find a pattern. It seems to be completely random.
 
 Any ideas whats wrong or how to fix this? Any help would be much
 appreciated as i'm out of ideas :(
 
 Thx

One possibility is swap trashing (running so low in RAM that every instruction 
takes several swaps to execute), especially with /var/tmp on tmpfs! This can 
happen even if you don't have a swap partition. Try with either more RAM or 
/var/tmp on a physical filesystem.

   xorg-server. I might look into it some other day but now i just wanted
   something working.
   
   Now i'm playing with using qemu-arm [1][2] in order to compile the
   packages inside a chroot. This is - so far - the most promising method
   building packages, even though the compile times are worse than with
   crossdev, but still better than directly on the rpi.
   
   So far i finally could compile xorg-server and also updated the whole
   system, which, at this point, wasn't much anyway. My next goal was kde.
   I've compiled about half of all packages which are required for
   kdebase-meta, but now i'm stuck at kdelibs and i have no idea what's
   wrong.
   
   The problem:
   
   The problem is, the compile doesn't fail - it just hangs/stops. At some
   point (which seems to be random - it can stop anywhere between 1% and
   100% of the compile) the compile stops and does nothing. I've waited
   hours, but nothing happened.
   So far i tried lots of things, for example:
   * MAKEOPTS=-j1 and/or FEATURES=-sandbox
   * also tried without building binary packages (-buildpkg)
   * /var/tmp on tmpfs
   * using: ebuild /usr/portage/kde-base//kdelibsebuild compile
   * using python3.3 instead of default 2.7
   * moved it on a different system and tried building it there (again with
   many different settings)
   
   Nothing worked, even though the build moved until 100% two times (-_-)
   
   I have no idea what the problem is. Even qtwebkit, which took way longer
   to compile (about 3 hours) compiled on the first try. (which should
   exclude temperate and/or resource problems)
   I also don't think it's a problem with a use flag as the build stops
   anywhere - i couldn't find a pattern. It seems to be completely random.
   
   Any ideas whats wrong or how to fix this? Any help would be much
   appreciated as i'm out of ideas :(
   
   Thx

  One possibility is swap trashing (running so low in RAM that every 
instruction 
  takes several swaps to execute), especially with /var/tmp on tmpfs! This 
can 
  happen even if you don't have a swap partition. Try with either more RAM 
or 
  /var/tmp on a physical filesystem.
  
 Usually /var/tmp is on the physical filesystem anyway. I've tried it
 just once or twice because i though about a performance problem. RAM
 shouldn't be a problem too as i'm having 16GB of RAM available.
  

I would tell you to attach a debugger and see if you can tell why it's hanging 
but that may not be worth the trouble (since it'll be a child process that's 
hanging it'll be tricky to start qemu with the gdb stub just for that 
process). If you want to try it see: 
http://tinkering-is-fun.blogspot.com/2009/12/debugging-non-native-programs-with-qemu.html
 and 
search QEMU_GDB for the tricky part.

Have you tried a different qemu version?

Did you find that documented somewhere or did you use an UI to create the file

When I started using NetworkManager I had hell trying to modify that file 
manually because plasma-nm ask for root password when modifying system wide 
connections but it doesn't save the changes (the solution was to run nm-
connection-editor manually as root). The same applies to nmtui and it only 
covers a few options. I don't remember exactly what needed to be changed in

It comes with CLI tools but it's usually used with a frontend GUI. See

For KDE I use kde-misc/plasma-nm. If you don't have a desktop it propably

If you use systemd net-misc/netctl has a nice curses UI but I've only tried on

If so it's because you're using localtime and the kernel sets it to UTC.
Either disable that option or if you need localtime for windows you can also

Even late on the boot process the OpenRC log won't catch everything. I think

There's a few things you can try.

1. Go in the bios menu and reset it to safe defaults or similar setting. If 
that don't work play with the settings, especially memory settings (try 
lowering the frequency).

2. If the motherboard is dirty, clean it real good. This may sound crazy but 
I've had success spray washing it with a hose and drying it on a warm oven.

3. Flash the bios with the latest version.

4. If you have a soldering iron and junk parts laying around replace any blown 
capacitors on the board.

 I've got a reproduce-able failure to suspend-to-ram with =3.18.x gentoo

You can use git. I believe gentoo patches are only for config options so if you 
configure it with make oldconfig it *should* be the same as using gentoo-
sources.

cd /usr/src
git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-
stable.git
cd linux-stable
git checkout v3.18.9
make oldconfig
make

You can checkout any version committed prior to your last git pull

You got me curious as to why they're there being redundant and I think I found 
out why.

I looked at the code (gcc/config/i386/driver-i386.c) and there is a very slim 
chance that the -march reported by gcc when using -march=native will not be 
the most appropriate. In some cases it's guessed based on the features 
reported by the CPU but on other cases it trusts the model number and Intel 
lists several Atom server CPUs and SoCs with no extensions at all (I have no 
idea what they report themselves like or if their specs are right). All the -
mxxx and -mno-xxx flags are determined by the features reported by the CPU so 
no chance of error there (save from a CPU bug).

I guess gcc devs are careful when using the model numbers (Intel lists 3 for 
Atoms, gcc uses only two so that may account for the models I mentioned) but 
the chance of error is there. The -mno-xxx flags would safeguard against it.

 In the case of chromium, the build system adds -msse4.1 for specific
 files (just the ones using SSE4.1 instructons). When you have
 -mno-sse4.1, this takes precedence and the build fails.

[gentoo-user] Deleted kdevelop ebuilds

2015-02-27 Thread Fernando Rodriguez


I've been using kdevelop-4.7.0 (unstable) for a while and it was working just 
fine. Then about a couple weeks ago it's ebuild got deleted from the portage 
tree and replaced with kdevelop-4.7.1 which is broken (I have issues with 
remote debugging).

Why does a good ebuild gets replaced with a broken one? Is there any way to 
make sure that packages that I'm using don't get removed from the portage tree
or at least that the package doesn't get downgraded automatically. Right now 
if I install an unstable package by keywording a specific version and it gets 
deleted you get downgraded the next time you run emerge -vauDN so you have no 
simple way of going back to your working configuration since the ebuild is 
gone.

  Try to print it from gdb cli, if it works you'll know the issue QtCreator,
  otherwise you're likely missing some symbols. You should always compile

 You don't need debug symbols for inspecting containers. They are not 
 needed. The only reason for enabling debug symbols in Qt is if you want 
 to step into Qt's code.

Thank you. You do need symbols though, just not Qts for this specific case. 
There are many reasons why you should compile your development libraries with 
symbols besides stepping into the code. Such as getting a backtrace. Even 
proprietary (closed-source) libraries often make the symbols available for 
this reason.

 these two electrons you instantaneous influence the quantum attributes 
 of the other one, regardless of its distance. But if you wanna know the
 quantum attributes of the second electron you need the information

 this information faster than light you also cannot use quantum 
 teleportation to really transmit information faster than light.

The best laymen terms explanation I've heard of this is by Murray Gell-Mann in 
The Quark and the Jaguar. The state is really determined when the particles 
are entangled. The principle of uncertainty holds because we cannot know the 
state until we make the measurement but there's no spooky action at a 
distance.

I don't know Vala but I can tell you what's going on. It's a version mismatch

still changing. So the answer is to file a bug with gentoo.

However you can get it to compile with valac-0.24 but it looks for valac-0.26 
so:

# mv /usr/bin/valac-0.26 /usr/bin/valac-0.26.old
# cp /usr/bin/valac-0.24 /usr/bin/valac-0.26
# emerge dev-libs/granite

And then restore the original valac-0.26. This will compile successfully but 
with several warnings so it may not actually work.

Yes. Also, if you compiled with any optimizations compile again with none. 
That way the compiler will try to generate code that matches the order of your 
C statements. It doesn't guarantees that this won't happen but with 
optimizations if you try to step through the source it'll definitely be jumping 
back and forth. The first statement here is line 126 but it may be optimized 
away or out of order. Also for source code debugging it'll be much easier to

You'll have to play with the options to test my idea. It doesn't need to

if the flash player crashes. There's an update on that page that the change has 
been delayed.

The error on the link that you posted looks like cause by pump mode, this one 
I'm not so sure.

It looks like you're not using the cross compiler on the host as it would not 
generate 64 bit code. Did you add -m32 to your CFLAGS on the client box? Also 
you may need to set the custom-cflags use flag. Can you verify that it is using 
the cross compiler on the host?

I'm not sure exactly what the gentoo recommended distcc/cross compile setup 
but if you do it like I suggested on your other thread (using the host 64bit 
compiler) it should work. Look at the links you got under /usr/lib/distcc/bin. 
All you need to do is create scripts on the host with the exact same names and 
have them execute the compiler that you want with the options you want (I just 
have it execute the 64bit compiler with -m32). Then make sure that distccd (on 
host) finds them before the actual compiler by putting it in the PATH 
environment variable before anything else. For that you may need to modify the 
init script or unit file if using systemd or just start distccd manually.

A simpler hack is to just delete the c++, cc, gcc, and g++ symlinks from the 
/usr/lib/distcc/bin directory. That will force distcc to only trap the 
compiler invocations that use the full compiler name and end up using the 
cross compiler in the host, but if you do this you may end up compiling more 
stuff locally.

Why is seamonkey the only program (so far for me) that needs -m32?
  Would it need -m64 if it was being cross-compiled on a 32-bit host

  info to?
 
 It has to do with my last post. Basicly the makefiles are invoking the full 
 compiler name for the files that are meant to run on the target but it 
invokes 
 just gcc for the files that are meant to run on the host. This is in the 
 context of cross-compiling, not distcc, so the file that's failing is meant 
to 
 run locally (it's a custom build tool). If you where compiling locally (or 
in 
 two machines with the same compiler) it would not matter cause the host and 
 target compiler are the same, but when distcc comes in it builds those files 
 with the host (system) compiler on the host.
 
 Changing the c++, cc, gcc, and g++ symlinks to a wrapper script that invokes 
 the compiler by it's full name as show in the RaspberryPi wiki page *should* 
 fix it.
 

That sounds confusing cause I use host to mean distcc host at one point and 
host compiler on another. I will use server to refer to distcc host on this 
post. When you run a GNU standard configure script you can specify two 
compilers, the host and target compiler. When compiling locally they're both 
the same. But when cross-compiling the host is the system compiler and is used 
for compiling things that will be executed as part of the build process (most 
packages don't do this). On gentoo this is set from the CHOST variable on 
make.conf, but either it's not usually passed to configure scripts by portage 
or some scripts just ignore it and invoke the host compiler as cc, c++, g++, 
or gcc.

When cross-compiling the target compiler is the one for the target 
architecture where the package will be deployed to. This is always invoked by 
the full name (on GNU compliant packages).

Distcc just traps the compiler invocations on the client and perform the same 
invokations on the server. In your case the seamonkey is trying to compile 
something with the host compiler, distcc is trapping it and compiling it with 
the host compiler on the server. Since the host compiler in the server is not 
the same as the host compiler on the server things go bad.

So you don't need -m32 unless you want to use the host compiler on the server. 
Since you want to use a cross-compiler on the server that was an ugly hack 
because you're actually using both compilers on the server. If the version of 
the cross-compiler gets out of sync with the host compiler things can go bad 
easily. So the proper fix in your scenario is to get rid of the -m32 and make 
the host compiler links a wapper script so that everything is compiled with 
the cross-compiler on the server.

On Saturday, May 02, 2015 9:10:01 PM Walter Dnes wrote:
   I ran into a couple of problems with distcc cross-compiling on a
 64-bit host for a 32-bit host.  One was with ffmpeg, and the other
 one was seamonkey (built-from-source).  There's a thread at
 http://www.gossamer-threads.com/lists/gentoo/user/298324 which mentions
 ffmpeg with symptoms identical to mine.
 
   ffmpeg is no problem doing locally.  But seamonkey built-from-source
 is a 14 hour marathon on the ancient 32-bit Atom.  It's the reason I got
 into distcc in the first place.  Fortunately, seamonkey-bin exists, and
 builds properly.  Basic Youtube videos (End Of The Line; Travelling
 Wilburys; HTML5; H264; 360-line-resolution) peg the double-core Atom
 with a cpu load of 2.75.  That's not Seamonkey's fault; what do you
 expect from an Atom, driving an un-accelerated framebuffer?  I'm happy
 that the devs went to the trouble of reverse-engineering the Poulsbo
 (bleagh) chip.
 
   The thread listed above mentions that distcc without pump can
 sometimes solve crossdev build problems.  Can it be used to build
 seamonkey from source on the host and manually push it to the client?
 
   While we're on the topic of distcc, it's update time.  The client
 shows...
 
 aa1 ~ # gcc-config -l
  [1] i686-pc-linux-gnu-4.8.4 *
 
 ...and the host shows...
 
 [d531][waltdnes][~] gcc-config -l
  [1] i686-pc-linux-gnu-4.8.3 *
 
  [2] x86_64-pc-linux-gnu-4.8.4 *
 
 According to the crossdev --help listing...
 -S, --stable Use latest stable versions as default
 -C, --clean target   Uninstall specified target
 
   This implies that on the host, I should do the following...
 
 crossdev -C -t i686-pc-linux-gnu
 crossdev -S -t i686-pc-linux-gnu
 
   Before I take the plunge, can anybody with experience confirm that
 this is the correct way to do it?
 
 

The difference is that without pump mode the source files are run through the 
preprocessor locally and a single preprocessed file is sent to the host for 
each compilation unit. With pump mode the actual source is sent to the host 
and it request the headers from the client as needed and the host caches them 
so they're only sent once. So pump mode uses less network traffic but it's not 
necessarily  faster, in fact it's much slower in some cases.

Some packages do custom preprocessing and other weird things during the build 
process that cause problems with pump mode since it caches copies of the 
unmodified headers. If you're lucky it just fails (and usually falls back on 
compiling locally), if you're not then it may succeed and you'll get runtime 
bugs. I haven't find a package yet that fails without pump mode as long as your 
CFLAGS are set properly.

As for updating, you likely don't need to. According to the distcc FAQ the 
minor version number is not as important. If you still want to, I *think* you 
can just mask the other versions using an atom like cross-i686-pc-mingw32/gcc 
to ensure that you get the version you want but I'm not sure about this and 
there may be a better way.
