[08:42:43] <cradek> seb_kuzminsky: http://article.gmane.org/gmane.linux.distributions.emc.user/51828
[08:43:21] <cradek> it isn't really our package's job to install this, is it? I have a working x-www-browser on my debian machine(s) and I don't recall doing anything special to get it. I wonder if it's gnome breakage or something?
[09:09:24] <seb_kuzminsky> i saw that last night, and like you i verified that my freshly installed debian 7 VM has x-www-browser
[09:09:38] <seb_kuzminsky> i foolishly decided to ignore the OP :-(
[09:11:16] <seb_kuzminsky> it's probably our package's job to Depend on something that provides a browser, and to call the system browser by some generic name
[09:11:28] <seb_kuzminsky> i had thought that the generic name to use was 'x-www-browser', but now i'm not sure
[09:11:39] <seb_kuzminsky> there's no virtual package named x-www-browser in debian 7
[09:11:57] <seb_kuzminsky> there is 'gnome-www-browser' and 'browser'
[09:12:14] <seb_kuzminsky> 'browser' can be satisfied by the text-mode browsers like links
[09:12:47] <seb_kuzminsky> i think (on debian 7 at least) depending on and calling gnome-www-browser is maybe more correct that x-www-browser?
[09:28:58] <cradek> weird. I have gnome-www-browser but I don't really have (much of?) gnome
[09:47:10] <skunkworks_> I can't belive you have any gnome... isn't that against your religion? ;)
[09:48:33] <cradek> you get some of the gnome bits whether or not you want the gnome desktop, I think because common applications need those bits
[09:49:09] <cradek> I don't know how it all works
[09:49:18] <skunkworks_> heh
[09:53:03] <skunkworks_> I installed 2.7 on my laptop last night - everything runs (sim on 14.04) I forgot to try it after you actually merged it to master.
[09:53:43] <skunkworks_> I did have halscope crash on me one while doing all the testing.. (would not launch again saying that it was already running) will keep an eye out for it
[09:53:49] <skunkworks_> once
[09:53:59] <cradek> hmm...
[09:54:37] <skunkworks_> I think I was changing the number of channels - poof - disapeared.
[09:54:57] <skunkworks_> but like I say - first time that has ever happened to me.
[09:55:18] <cradek> was it a sim or realtime build?
[09:55:21] <skunkworks_> sim
[09:55:27] <skunkworks_> my laptop
[09:55:42] <cradek> if you do "ulimit -c unlimited" before you run linuxcnc, a crash will give you a core dump, which is useful
[09:55:52] <cradek> if you can ever reproduce it, of course :-(
[09:55:53] <skunkworks_> ok
[09:55:57] <skunkworks_> right
[09:56:34] <skunkworks_> I use halscope all the time but don't change the number of channels very ofthen. I will beat on it when I gat a chance)
[09:56:38] <skunkworks_> get
[09:57:05] <skunkworks_> ofthen? this is my 3rd cup...
[10:22:13] <seb_kuzminsky> cradek: gnome-www-browser is a virtual package, meaning it doesn't exist but other packages Provide: it
[10:22:54] <seb_kuzminsky> epiphany, iceeasel, and chromium all provide it
[10:24:52] <seb_kuzminsky> there's also a 'www-browser' virtual package
[10:25:30] <seb_kuzminsky> Precise has the same two virtual browser packages
[10:26:46] <seb_kuzminsky> on my laptop, gnome-www-browser points to chrome, but www-browser points to links
[10:27:05] <seb_kuzminsky> i wonder what happens on kubuntu... konqueror doesn't provide gnome-www-browser, obviously
[10:27:54] <seb_kuzminsky> konqueror provides www-browser
[10:27:55] <skunkworks__> this is where you are trying to call the default browser?
[10:28:01] <seb_kuzminsky> yeah
[10:28:17] <seb_kuzminsky> frmo the system menu items that lead to our html docs
[10:28:29] <pcw_home> skunkworks_: I've had HALScope up for 50 days 24/7 now on my
[10:28:31] <pcw_home> Ethernet test rig (12.04 Preemt-RT) with no problems, but I'm not poking at it
[10:28:31] <cradek> and x-www-browser is none of those
[10:29:15] <seb_kuzminsky> maybe it was back in like 2005 when someone added that line
[10:29:31] <seb_kuzminsky> chromium Provides www-browser, i wonder why my system picked links instead?
[10:30:52] <skunkworks__> pcw_home: nice!
[10:31:00] <skunkworks__> I have not set back up yet..
[10:31:10] <seb_kuzminsky> chromium doesn't appear to have registered itself as a target for www-browser with update-alternatives
[10:31:16] * seb_kuzminsky is confused...
[10:31:44] <seb_kuzminsky> i'm going to ignore this issue for now and work on the rtai kernel instead
[10:32:10] <seb_kuzminsky> if no one else is going to pick it up, let's ask the OP to open a bug for it
[10:34:29] <cradek> by all means, the kernel is more important
[10:51:50] <pcw_home> seb_kuzminsky is cooking up a new RTAI kernel?
[10:57:51] <seb_kuzminsky> trying to
[10:58:29] <seb_kuzminsky> the 3.4.55-rtai kernel we have is a little out of date, and the packaging is kind of ... amateurish
[11:02:10] <pcw_home> another 3.4.x kernel?
[11:11:14] <CaptHindsight> probably has to see what works
[11:11:44] <seb_kuzminsky> yeah, 3.4.87 (that's the latest 3.4 LTS kernel supported by Shabby's RTAI)
[11:12:01] <seb_kuzminsky> i spoke iwth shabby and he said he thinks it works for both 32-bit and 64-bit
[11:12:34] <seb_kuzminsky> i'll know in a couple of days hopefully
[11:15:00] <skunkworks_> A couple of days!! ;)
[11:18:22] <seb_kuzminsky> uh oh
[11:52:52] <CaptHindsight> memleak said that if somebody fixes the scheduler then even 3.13 should work
[11:53:25] <CaptHindsight> 1) fix the scheduler in RTAI
[11:54:09] <CaptHindsight> 2) math support in kernel kconfig has changed and no options seem to work with Linuxcnc
[11:54:44] <CaptHindsight> 3) Linuxcnc needs to fix /proc in order for any 3.10 or newer RTAI kernels to work
[11:57:42] <CaptHindsight> One workaround for the broken scheduler is with isocpu= you need to leave the last cpu core out of the list. For example isolcpus=1,2,3 for a 4 core and it should work or a single core cpu should work fine.
[11:58:24] <CaptHindsight> that's the scoop for RTAI :)
[12:27:25] <IchGuckLive> hi all how do i compile a module sutch as a new kinetics for gantry homing
[12:27:35] <IchGuckLive> its a c file
[12:29:14] <IchGuckLive> ok done
