[arch-general] RFC on a WIP detailed class outline on static typing
by Sam Stuewe 08 Dec '14

08 Dec '14

Hello everyone! I have been working on "A Gentle Introduction to Static Typing" to be taught in the Arch Classroom for a little while now, and I am hoping to get some more feedback on the detailed outline I have before we set a date for the class. The class is meant to only be an hour or two long (but I would not be inherently against it splitting into two sessions as-needed if those attending feel it is needed), and so the material covered is fairly basic. In fact, this class, though it is a general introduction, is meant to be a basic groundwork lead-in to an Intro to C class I intend to teach later on. The outline may be found here (https://gist.github.com/HalosGhost/aaf5ea068ef0f2854a3c), and all comments, questions, concerns and suggestions are welcome. I will be monitoring this thread, as well as the related BBS thread (https://bbs.archlinux.org/viewtopic.php?id=190788) and the comments on the Gist itself. Feel free to reply wherever you are most comfortable. -- All the best, Sam Stuewe (HalosGhost) All the best, --- Sam Stuewe

[arch-general] Java Problem
by Hunter Jozwiak 08 Dec '14

08 Dec '14

Hello: I have come accross an interesting issue with Java. Let's say I fashion a simple Hello World app, and entitle it hello.java The code would be: class hello { public void main(String[] args) { System.out.println("Hello World!"); } } Then, I compile the code as a regular user, with javac hello.java Here's the odd part: I type java hello, and I get unable to find main class hello But, if I run sudo java bhello, it works fine. What is the solution to not having to run Java software as sudo?

[arch-general] Official policy on beta releases in mainline repos
by Troy Engel 06 Dec '14

06 Dec '14

If this is on the wiki or elsewhere I've missed it, please feel free to direct me there. What is the official policy on beta releases in the mainline repositories? Is there one? $ pacman -Ss | grep ^[a-z] | grep beta core/grub 1:2.02.beta2-5 extra/foobillard++ 3.42beta-5 extra/frozen-bubble 2.2.1beta1-6 extra/hddtemp 0.3.beta15.52-2 extra/libcaca 0.99.beta18-2 [installed] extra/libunicodenames 1.1.0_beta1-1 extra/tsocks 1.8beta5-7 extra/ttf-tibetan-machine 1.901-6 community/echat 0.04beta1-4 community/fatrat 1.2.0_beta2-14 community/freerdp 1.2.0_beta1+android9-1 community/krecipes 2.0beta2-6 community/krusader 2.4.0beta3-5 community/sniffit 0.3.7.beta-15 community/vbindiff 3.0_beta4-4 community/wqy-microhei 0.2.0_beta-6 community/wqy-microhei-lite 0.2.0_beta-6 community/xmove 2.0beta2-6 I'm specifically concerned about the choice to release betas of freerdp into mainline and was trying to find out what the policy was and when it was deemed OK to release betas. (as with grub). I am not finding the reason for a freerdp upgrade documented to use the betas, a lot of us use this tool for work and can't afford to deal with the hits of beta software in a critical utility. thx, -te [1] https://bbs.archlinux.org/viewtopic.php?id=190317 [2] https://bugs.archlinux.org/task/42890

[arch-general] mpv in [community] compiled against different version of ffmpeg than in [testing]
by Savya 06 Dec '14

06 Dec '14

I was running mpv from the terminal today, and I got an unexpected message: "Warning: mpv was compiled against a different version of ffmpeg than the shared library it is linked against. This can expose subtle ABI compatibility issues and can lead to misbehaviour and crashes." Installed versions of packages: [testing]/ffmpeg: 1:2.5-1 [community]/mpv: 0.7.1-1 I would request (if possible, of course), that mpv in community be compiled against the version of ffmpeg in [testing] and put in the [community-testing] repo whenever ffmpeg is in [testing]. Thanks! -- Cheers! Savya

[arch-general] ibus
by Ralf Mardorf 05 Dec '14

05 Dec '14

Hi, I'm surprised why ibus is installed on my machine. Is ibus needed for anything on my machine? The package claims that it was "Installed as a dependency for another package", but no package seems to need it. $ pacman -Qi ibus Name : ibus Version : 1.5.9-4 Required By : None Optional For : None Conflicts With : None Replaces : None Install Reason : Installed as a dependency for another package $ pactree -r ibus ibus I replaced two packages with dummy packages, non of the "original" packages does need ibus. $ pacman -Si pulseaudio gvfs | grep ibus Has got ibus any effect, when no other package requires it? Regards, Ralf

[arch-general] Built packages of GCC 5
by Kalrish Bäakjen 02 Dec '14

02 Dec '14

Hello, I am working on a nasty machine that is slow and sporadically freezes, which makes it unable to compile anything that takes a bit of effort. I would like to try GCC's development version, but it's not possible to build it locally. Do you know of any (unofficial) respository that offers i686 packages of GCC 5? By the way, would there be any problems with system libs if a development version was installed (in place of the stable one, which is 4.9.1)? Thanks, Kalrish
