Ubuntu 16.04 / gcc 5.4.0 - errors generated inside system include files
by Stewart C. Russell 08 Aug '16

08 Aug '16

I'm hitting unexpected problems building some old-ish code (UCB Logo 6, after hearing Seymour Papert went PENUP last week). gcc seems to be choking on its own header file, mathcalls.h: gcc -g -O -O0 -DUSE_OLD_TTY -c -o coms.o coms.c In file included from coms.c:30:0: /usr/include/x86_64-linux-gnu/bits/mathcalls.h:100:1: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘extern’ __MATHCALL_VEC (exp,, (_Mdouble_ __x)); ^ /usr/include/x86_64-linux-gnu/bits/mathcalls.h:100:1: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘extern’ __MATHCALL_VEC (exp,, (_Mdouble_ __x)); ^ /usr/include/x86_64-linux-gnu/bits/mathcalls.h:100:1: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘extern’ __MATHCALL_VEC (exp,, (_Mdouble_ __x)); ^ <builtin>: recipe for target 'coms.o' failed make: *** [coms.o] Error 1 (this on Ubuntu 16.04, gcc 5.4.0, x86_64) I can build other code that includes math.h, the source of the mathcalls.h inclusion. The package builds fine on a Raspberry Pi (Raspbian, gcc 4.9.2, armv7l). The package even built on x86_64 under Ubuntu 15.10. Is this just Canonical mucking about with the compiler settings again? cheers, Stewart

cheap Raspberry Pi, today only
by D. Hugh Redelmeier 05 Aug '16

05 Aug '16

Newegg.ca has two or three "Shell Shocker(TM)" deals each day. Sometimes they are pretty good. Today, one is a Raspberry Pi 3 Model B for $42.90 + shipping and tax. Ground shipping is $7.99 but you can probably use "InPost" shipping which should be free. InPost will ship it to a locker of your choosing. For me, the locker is very convenient (in a Loblaws site a short walk from home). Canada Robotix (a store in Markham) sells the RPi3 for $53.99. Creatron on College sells it for $53.50.

Re: [GTALUG] [gta-bb-group] How to Install and Use the Linux Bash Shell on Windows 10
by James Knott 04 Aug '16

04 Aug '16

One thing, you may want to create a regular user, for just starting the shell and root when you run in administrator mode. That way the privileges follow the user.

GUI for Ubuntu 16.04
by Stephen 04 Aug '16

04 Aug '16

I have been running 14.04 and have no reason to upgrade. But I am being prompted when updates are performed. I prefer the tradition Gnome interface with a menu bar at the top. I dislike tile based stuff. I have Googled trying to find if I can get my preferred interface in 16.04 but I cannot see the topic addressed. All I see are demos for the new interface. So I am turning here and hope someone can me find out if/how I can use the traditional menu bar. Cheers -- Stephen

FCC "forces" TP-Link to enable open source on their router(s)
by D. Hugh Redelmeier 03 Aug '16

03 Aug '16

<http://arstechnica.com/information-technology/2016/08/fcc-forces-tp-link-to…> I don't quite get it. The FCC made a rule that was easy to comply with if the manufacturers prevented loading of third party firmware. (The rule: don't let you user set the router to use too much signal strength.) TP-Link's new firmware "could not" be replaced by 3rd party firmware. That firmware also allowed out-of-spec signal strength. As a settlement, FCC required TP-Link to pay a fine, to allow third party software, and to update the firmware to not allow the user to specify (through the GUI) too much signal strength. So the original problem remains: how can TP-Link prevent existing hardware from generating too strong signals if it cannot control the firmware?

Android <--> KDE = KDE Connect
by William Park 03 Aug '16

03 Aug '16

Something I discovered recently... KDE Connect. - install "KDE Connect" app on Android phone. - modern KDE desktop should come with "KDE Connect" (System Settings | Hardware). It "pairs" Android phone and KDE desktop together, so that you can - remote control mouse/keyboard from phone. When you type on the phone or touch the screen, it shows up as keystrokes or mouse movement on desktop, respectively. - transfer files from phone to desktop. - transfer files from desktop to phone. Unfortunately, it doesn't work on Slackware, but works on Kubuntu and KaOS. -- William

Advice -- Building Debian 8 PC To Replace Win XP PC;
by Steve Petrie, P.Eng. 02 Aug '16

02 Aug '16

Warm Greetings To GTALUG, Please forgive the long email. -- have to provide some background. BACKGROUND -- BUILDING DEBIAN 8 PC TO REPLACE WIN XP PC I'm working to replace an old Dell Windows XP SP3 PC with a new PC, booting Debian Linux 8 as the primary OS, with Win 7 set up to run under QEMU / KVM vbirtualization under Debian. A multi-boot setup will allow booting Windows 7 (OEM) on bare metal, if required for occasional use. I definitely am NOT going to use MS Windows as the primary OS in my new desktop PC !! I have almost no Linux / Unix experience. Some years ago doing application programming on IBM AIX / Korn shell and now for personal and business uses, getting into Debian Linux (and DragonFlyBSD) on cloud-hosted QEMU / KVM virtualization servers. However I do have a strong IT background. (I'm a "retired" software engineer). On 7 January 2016 I sent an inquiry email to hi(a)gtalug.org and Myles Braithwaite responded instantly with helpfull suggestions for which I was very grateful. Myles also encouraged to join the talk(a)gtalug.org mailing list and so now here I am. I'm looking for advice from GTALUG members on two issues: 1. Comments on my proposed PC configuration. I have already researched components and developed a detailed hardware configuration for the new PC. Please see below. This configuration is not yet published on ca.partpicker.com. 2. Advice on how to get the PC built from components, that I will purchase retail and supply to the builder. Here, one option I propose is for a "creative" solution from GTALUG (see point 3, next section). * * * * * * HOW TO BUILD THE NEW DEBIAN 8 PC ? It seems to me that there are three approaches I could take, to get this new PC built: 1. BUILD IT MYSELF. I can handle purchasing all the components. However, although I am comfortable messing around inside the case of a computer, I've never build one from components. I would prefer to have the PC assembled by more experienced hands that have the skills and use of the right tools. So building myself is a last resort. 2. USE A COMMERCIAL PC SYSTEM BUILDER. Any suggestions from mailing list participants, on commercial PC builders would be gratefully received. However, I do not want to have to deal with import hassles, so the builder must be operating in Canada.(preferably in the GTA) Problem: It seems it will be difficult to interest commercial PC bulders in Canada to supply a competitively-priced PC configured with Linux. So if I use a commercial builder, the plan would be to get the PC built and delivered with with Windows 7 only installed, but have a multi-boot setup. After I get the PC I will install Debian 8 Linux as the primary host operating system, and then install Win 7 to run under QEMU / KVM virtualization under Debian. 3. *** CREATIVE IDEA FOR GTALUG *** Perhaps there is a member (or members) of GTALUG who would be able to build the PC from comnponents I supply. Naturally I would be happy to pay a fee for this service Or (and this would be my preference) perhaps GTALUG would be interested in taking on the buuild project as a club project. I expect I would be much more happy to pay money to GTALUG for helping with the build, and to get the pleasure of working with GTALUG, than I would be paying and dealing with a commercial builder. Since I live in Oakville in a small apartment, it would make more sense for the build to happen in Toronto. >From my casual research, there are many Win XP "orphans" like me out there. Not only older-type people stuck on Win XP and wondering what to do before their old PC dies. But also there are plenty of small businesses still running XP (in fact there are probably more small business XP users left, than consumer XP users). You could consider me in a sense, a "poster senior" for a class of people, among whom some could possibly go the Linux route as they migrate away from Win XP. If only these poster seniors (or small business Win XP "orphans") had a helping hand from e.g. GTALUG. For example, run a kind of GTALUG "clinic" that Win XP "orphans" could come to (for a fee) and there work with GTALUG members to get their Linux PC built. And later get their data (e.g. emails) converted over to e.g. Thunderbird. Just a thought, for a way that GTALUG could get more involved with the wider community. And perhaps also pull in some club revenue to support GTALUG initiatives. Perhsps this is an idea the GTALUG Board could consider. I am happy to discuss the idea of being the "guinea pig" for such a project. * * * * * * PROPOSED PC CONFIGURATION Thsi is decidedly NOT a gamer's PC.
