[arch-general] gcc: loop do not terminate

I have just been hit by something: lano1106@hpmini ~/dev/gcc-test $ g++ --version g++ (GCC) 4.8.0 20130502 (prerelease) Copyright (C) 2013 Free Software Foundation, Inc.

For example int SATD (int* diff, int use_hadamard) { int k, satd = 0, m[16], dd, d[16]; ... for (dd=d[k=0]; k<16; dd=d[++k]) satd += (dd < 0 ? -dd : dd); accesses d[16] before the loop is exited with the k<16 check. This causes the compiler to optimize away the exit test because the new value of k must be in the range [0, 15] according to ISO C. GCC starting with version 4.8 has a new option -fno-aggressive-loop-optimizations that may help here. If it does, then this is a clear sign that your code is not conforming to ISO C and it is not a GCC bug. I am surprised that I didn't hit the problem before but I am seriously considering using '-fno-aggressive-loop-optimizations' in my own makepkg.conf. I just want to test others feeling on this discovery to see if it wouldn't be a good idea to make the switch standard in Arch... ________________________________ CONFIDENTIALITY : This e-mail and any attachments are confidential and may be privileged.

[arch-general] libvirtd - save shutdown and systemd
by Guus Snijders 14 May '13

14 May '13

Hey all, I'm pretty sure this is a fairly basic question, but i am a bit confused on systemd targets. It has been a while since i converted my systems to systemd and most of it seems to be working ok. Now i am looking for a way to automatically save my VM's to disk in case i forget to shutdown/save one before shutting down the host. After some searching, i stumbled upon this in man systemd-halt.service: " Immediately before executing the actual system halt/poweroff/reboot/kexec systemd-shutdown will run all executables in /usr/lib/systemd/system-shutdown/ and pass one arguments to them: either "halt", "poweroff", "reboot" or "kexec", depending on the chosen action. All executables in this directory are executed in parallel, and execution of the action is not continued before all executables finished. " So at least one way would be place a script that calls "/etc/rc.d/libvirtd-guests stop" (or equivalent, it's not hard to replace) in /etc/systemd/system-shutdown/ . My main question is if this would be a "correct" way or that i could better write some custom unit file to do this? The tricky part is that i am /not/ interested in an automatic resume of previously running guests, only saving them in case i forgot. I'd be very interested in hearing opinions. mvg, Guus

[arch-general] gtkmm and VMware Workstation
by Guillermo Leira 13 May '13

13 May '13

Hello! An advice for VMware Workstation users: upgrading to gtkmm 2.24.3-1 on x86_64 makes VMware Workstation 8.0.6 crash on start or after a few seconds. I don't know about other versions. It happens with kernel 3.8.11 and 3.9.2. Downgrading to gtkmm 2.24.2-2 solves it (after an hour of trial and error). I'll create a bug report tomorrow. Too late for me now. Best Regards, Guillermo Leira

[arch-general] Linux 3.9.2-1-ARCH cures blank screen
by Whiskers 13 May '13

13 May '13

The blank screen I first reported in January with Linux-3.7.3-1-i686 seems to have been cured by the latest update to Linux-3.9.2-1-i686 (and/or other updates that have happened at the same time). (Using the nouveau graphics driver). But the desktop and mouse settings in XFCe4 aren't all working. -- -- ^^^^^^^^^^ -- Whiskers -- ~~~~~~~~~~

[arch-general] RME cards: How to show board revision and the loaded firmware version?
by Ralf Mardorf 13 May '13

13 May '13

Preliminary question and regarding to this question multiposted: Does anybody still use a RME HDSPe AIO ;)? Hi, since the issues I get for my RME HDSPe AIO didn't became less, but more within the last two years, I cleaned a primary partition to install XP, just to test, if there are issues caused by the mobo, that will appear, even when not using a *nix driver, but the proprietary driver and latest RME firmware. I'm a Linux only user, so sometime ago I installed FreeBSD, just to test, if the RME card isn't borked, since on Linux only 2 ADAT channels do work, fortunately all 8 ADAT channels work, using the FreeBSD driver (no TotalMix). I bought the card, because it was recommended by members of the Linux audio community. Don't get me wrong, the blame is on me, I decided to buy the card and had no time to use it within the first weeks, I only want to point out, that I did research before I bought the card. I wonder, if there are different revisions of the RME board? I know I've written this several times, but somebody might not have read it and it's a while ago since I ask for the situation of this card on other machines. Is there a command that shows the board revision and used firmware version? I run my Arch install without the alsa-firmware package and installed it now. $ uname -r 3.8.11-rt8-1-rt $ pacman -Q alsa-firmware error: package 'alsa-firmware' was not found $ sudo pacman -Syu alsa-firmware warning: ardour: ignoring package upgrade (2.8.16-1 => 3.1-1) alsa-firmware-1.0.27-2 $ pacman -Q alsa-firmware alsa-firmware 1.0.27-2 Can anybody use a HDSPe AIO on Linux with all available sample rates? Store alsamixer settings? Does hdspeconf run? Use latency <= 10.7 ms? Use any latency even => 10.7 ms with getting absolutely no xruns? Use all ADAT channels?

[arch-general] problems while upgrading kdelibs
by Shridhar Daithankar 13 May '13

13 May '13

Hello, While upgrading kdelibs-4.10.2-4 x86_64, I am getting errors such as these.. kdelibs: /etc/dbus-1/system.d/org.kde.auth.conf exists in filesystem kdelibs: /etc/xdg/menus/kde-applications.menu exists in filesystem kdelibs: /usr/bin/checkXML exists in filesystem kdelibs: /usr/bin/kbuildsycoca4 exists in filesystem kdelibs: /usr/bin/kconfig_compiler exists in filesystem kdelibs: /usr/bin/kcookiejar4 exists in filesystem kdelibs: /usr/bin/kde4-config exists in filesystem kdelibs: /usr/bin/kded4 exists in filesystem There are total 3503 such errors, all for kdelibs only. As of now pacman reports that none of them are owned by any packages but thats a suspicious claim since it includes files like /usr/bin/kbuildsycoca4 and /usr/bin/kcookiejar4. Initially I thought it was a package sync error and any updated packages will be pushed soon. But after 4 days the situation persists. Has anybody else seen this? Should I just use --force? TIA.. Reference - generate file # pacman -Syu --noconfirm > pacman.upgrade.log 2>&1 - check error # grep -c exists pacman.upgrade.log 3503 - check conflicting packages # grep exists pacman.upgrade.log |grep -v kdelibs - check package ownership for file in $(grep exists pacman.upgrade.log|cut -f2 -d' ');do pacman -Qo $file;done 2>&1|grep -vi "No package owns" -- Regards Shridhar

[arch-general] [linux] 3.8.12 is a binary module breaker, time to get 3.9.1 into [core]
by Tobias Powalowski 08 May '13

08 May '13

Hi guys, The 3.8.12 is a binary module breaker and cannot move to [core] as it is. I'll build and upload it, but not merge into [core]: https://dev.archlinux.org/~tpowa/linux Time to get 3.9.1 into [core]. Please test and signoff 3.9.1 real soon. greetings tpowa -- Tobias Powalowski Archlinux Developer & Package Maintainer (tpowa) http://www.archlinux.org tpowa(a)archlinux.org

[arch-general] Current "CPPFLAGS=-D_FORTIFY_SOURCE=2" break some builds
by Leonid Isaev 07 May '13

07 May '13

Hi, With gcc 4.8.0-4 I can no longer build core/links package from ABS, with SSL support. The issue is _not_related to makepkg (as I originally thought), even plain ./configure fails if I export CPPFLAGS=-D_FORTIFY_SOURCE=2, regardless of the content of {C,CXX,LD}FLAGS. Here is the error: -------------------- $ ./configure --with-ssl [ ... ] checking for openssl... yes checking OPENSSL_CFLAGS... checking OPENSSL_LIBS... -lssl -lcrypto checking for OpenSSL... no checking for OpenSSL... no configure: error: OpenSSL not found $ cat config.log [ ... ] configure:8095: checking for openssl configure:8102: checking OPENSSL_CFLAGS configure:8107: checking OPENSSL_LIBS configure:8139: checking for OpenSSL configure:8150: gcc -o conftest -g -O2 -D_FORTIFY_SOURCE=2 conftest.c -lssl -lcrypto -lm 1>&5 In file included from configure:8143:0: confdefs.h:8:16: error: duplicate 'unsigned' #define size_t unsigned ^ configure: failed program was: #line 8143 "configure" #include "confdefs.h" #include <openssl/ssl.h> int main() { SSLeay_add_ssl_algorithms() ; return 0; } -------------------- With gcc 4.7.2 all builds fine with Arch's default makepkg.conf, i.e. no "duplicate unsigned error". Also, unsetting CPPFLAGS allows a successfull build. Since core/links has been successfully rebuilt, what was the gcc version? ANd can anyone else confirm the above issue? TIA, L. -- Leonid Isaev GnuPG key: 0x164B5A6D Fingerprint: C0DF 20D0 C075 C3F1 E1BE 775A A7AE F6CB 164B 5A6D

[arch-general] Kernel panic at boot after hard reset: not syncing. No init found.
by Paul Hervot 07 May '13

07 May '13

Hello, I know some people had this problem before but no solution seems to help me. I was playing Kerbal Space Program, the game filled up my RAM, my computer was no longer responding (it happens to me a few times a month if I forgot to close firefox before playing for example). I had to hard shutdown, then on the boot I get this kernel panic. (Here is a screenshot: http://dettorer.net/kernel_panic.jpg) The init= parameter given by grub is correct: /usr/lib/systemd/systemd and I double checked the root= parameter, it is by uuid but I also tried by device name (/dev/sda7) and by label. I use three partitions: sda5: /boot (sda6: swap) sda7: / sda8: /home `fdisk -l /dev/sda` http://paste.awesom.eu/ux8 `ls -l /dev/disk/by-uuid` http://paste.awesom.eu/85U Using the output of a new `grub-mkconfig` didn't fix it either. Here is my grub.cfg: http://paste.awesom.eu/aDR I tried running `mkinitcpio -v -p linux` (I use the 3.8 kernel from core but also tried the 3.9 from testing, same result) Here is my mkinitcpio.conf: http://paste.awesom.eu/yVH and the output of `mkinitcpio -v -p linux` http://paste.awesom.eu/6f3 I checked the filesystems of my / and /boot partitions with badblocks and fsck, no problem from here. (I also tried reformating my swap with mkswap as the second line of kernel panic mention swapper even though I didn't understand that line, I just gave it a try). I don't know what to do now, my guess is that the initramfs can't mount the root partition but the root= parameter is correct and everything mount well under a liveCD (this is from where I try to fix it). PS: It's my first post on arch-general, sorry if my question is off-topic or poorly presented. -- Dettorer
