[arch-general] makepkg.conf CFLAGS
by Yamakaky 02 Jun '14

02 Jun '14

Hi I just discovered the gcc option march=native. It enables all the local-supported optimizations, without downsides except the non-portability of the binaries. Is there a reason why it isn't enabled by default, as cross platform compilation isn't used by most of the users (I think) ? Yamakaky

[arch-general] [Classroom] new class: A First Look at the Linux Kernel - Saturday, May 31 at 16:00 UTC
by fsckd 02 Jun '14

02 Jun '14

Hello, jy2wong will be teaching a class called, "A First Look at the Linux Kernel". The class will cover the role of kernels in a system, why you might want to consider compiling your own, and tips for not getting lost in the configuration process during your first Linux kernel compile. Prerequisites: While not necessary, it is useful to be familiar with ABS [1] before taking the class. If you are unfamiliar with PKGBUILDs, logs from past classes make an excellent primer. [2] The class will be Saturday, May 31, 2014 at 16:00 UTC in the IRC channel #archlinux-classroom on the Freenode network. If there is enough interest, the class may also be held a second time on that day for people from East Asia and Oceania. If you want the class being held again for those timezones, please reply to this email indicating so. About jy2wong in her own words: I'm a university student from Canada, studying/doing research in something involving signal processing (that lies somewhere between math and computers). I've installed Arch Linux on my laptop about 4 times now, and the first 3 times were in my first week of using Arch Linux (that was about 5 years ago). I've been compiling my own kernel for the last 3 or 4 years. I think I'm allergic to cats.

[arch-general] Linphone TLS cannot start on Port 50656
by Mark Lee 01 Jun '14

01 Jun '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Salutations, I recently installed linphone and found I would get an error on startup: - ----- Could not start tls transport on port 50656, maybe this port is already used. - ----- Several things there, I thought SIP with TLS usually used port 5061. Furthermore, upon inspection the linphone is not compiled with the flag "with-ssl" in the PKGBUILD. I added that flag myself, but still get the same error. Any idea what's going on with the TLS transport?

[arch-general] After gnutls update on 30-05-2014 `M-x gnus' crashes Emacs
by Thorsten Jolitz 31 May '14

31 May '14

Hi List, the gnutls version created at Fr 30 May 2014 15:25:49 makes Gnus unusable for me, since calling `M-x gnus' crashes Emacs with a Segfault (not immediately, but in the process of updating groups). I experience this after updating at 22:42:03 yesterday. Otherwise, Emacs works fine. Since Gnus is such a vital tool, it would be nice if this is addressed soon. Thanks. -- cheers, Thorsten

[arch-general] Recommended reading for Shell expansion mechanism
by Heiko Becker 31 May '14

31 May '14

Hi all, as I'm trying to give shell programming and things like that a start, I have a short question related to the shell expansion: I heard that it is possible to exclude things after using a wildcard like ./* for every file in the current directory. Am I right or did I misunderstand something? Is there some place on the internet where I can find things about expansions and such operations of the shell? Thanks in advance, Heiko

[arch-general] CA certifcates
by Eduardo Machado 30 May '14

30 May '14

Hi, some months ago i needed to setup a Certificate Authority and add it's root certificate to the client machines, so i figured out and added the CA certificate to /usr/share/ca-certificates, edited the /etc/ca-certificates.conf to reflect this and them run "update-ca-certificates --fresh --verbose". this added the CA to the SSL certs and generated the file with all the certificates in /etc/ssl/certs/ca-certificates.crt So when i used Firefox and Chrome, it reflected this and the server certificate was validated. But... This week, after a system upgrade both Firefox and Chrome, stopped to reflect this, even after i did all the above process again. Firefox and Chrome are not using the ca-certificates package? Is there a way to do what i'm trying to do (a central point to manage certificates for all apps, especially browsers)? And, a last question, is there a way to run a script after a specific package upgrade? Thanks, --- Eduardo M. Machado

[arch-general] qt3 PKGBUILD
by Denis Gagnon 29 May '14

29 May '14

Hello everybody It seems qt3 (https://www.archlinux.org/packages/?q=qt3) has been removed from the [extra] repository. Some packages in the AUR still depend on it though, such as https://aur.archlinux.org/packages/pdfedit/. Would it be possible to get the latest PKGBUILD so that qt3 can be uploaded on the AUR ? Thanks! -- Denis G. <gagnon88(a)gmail.com>

[arch-general] libpng warning - qt application
by Guus Snijders 28 May '14

28 May '14

I know this is hardly a new problem, and I know how to fix a 'broken' png file. The problem is finding that file. Here's the case; i recently started using a application ppqt[1], which shows this warning on startup. Displaying PNGs is a major part of this application and that doesn't work atm. To investigate, i did an strace, but that didn't turn out to be very helpful; the only png's mentioned are icons that are /not/ found. Does anybody here have some advice on how to find out which file could be the culprit in this? Or how to troubleshoot better? [1] https://github.com/tallforasmurf/PPQT mvg, Guus
