[16:01:14] <skunkworks> same effect - 12.04 has the missing symbol and 10.04 seems to comunicate but doesn't send the config and gets encoder errors.

[16:06:25] <pcw_home> If its a 7I80 you dont send a config
[16:06:53] <skunkworks> sorry - 7i80 - I mean the config line.
[16:07:18] <skunkworks> If I send it all 0 for pwmgen encoders and such - I still get the ecoder errors.
[16:08:28] <pcw_home> Maybe the config parsing is broken in the driver
[16:09:03] <norbert> Halo, I am working on a glade widget to load a file to linuxcnc using an IconView, so it is very touchscreen friendly. My widget do use some part of code witch is under the BSD license. I got also the permission from the author of the original code to use it. Does somebody know if it is allowed to relicense the code under GPL, or would it be a problem to include the code if it is under the BSD license?
[16:09:41] <cradek> which BSD license is it?
[16:10:18] <skunkworks> pcw_home, this is what I am seding.. loadrt hostmot2 loadrt hm2_eth ip="192.168.0.2" config="num_encoders=0 num_pwmgens=0 num_stepgens=0"
[16:10:32] <skunkworks> (other than it is the default ip address of the 7i80)
[16:11:01] <norbert> @cradek, the autor send me a mail with this information: The license for the code examples on ZetCode is BSD.
[16:11:31] <cradek> ok, that is not enough information to answer your question, because there are several licenses that people commonly call BSD.
[16:12:29] <norbert> I will than write an other Email to the author, just asking for his permission to public my code under GPL, Lets see waht he will answer.
[16:13:04] -!- PetefromTn has quit [Ping timeout: 264 seconds]
[16:13:09] <cradek> the license that gives us the most compatibility with the rest of linuxcnc is "GPL 2 or later"
[16:13:49] <cradek> but if you get clarification about which BSD license the author means, it may be just fine, since some are perfectly compatible
[16:15:32] <cradek> you might like to read

[17:11:02] <skunkworks> interesting... (I know when I first started in linux - I had a hard time figuring out where the usb drive was 'mounted'
[17:16:13] <kwallace2> We set and limit what files go where, when and how , so there is less chance for an operator to get lost. A Linux savvy person might find it too restrictive.
[17:17:13] <skunkworks> heh
[17:17:58] _BJFreeman is now known as BJfreeman
[17:18:44] <skunkworks> do you think they will put their setup in linuxcnc prime?
[17:26:20] <kwallace2> My impression is that once the lathe is released, there will be time to catch a breath, then present the software. I don't think there is a lot of motivation to push anything into LinuxCNC (only my view, Rogge knows better), but it should be available.

[19:35:25] <KimK> skunkworks: You said earlier you were trying installs. Did these have anything to do with the debs that Seb (and others?) posted before Seb left? Reason being, I have another E350N available now, and it's needing an install. So I'm wondering whether I should copy my other E350N install (the one that mhaberler and zultron posted before the fest), or is there some more recent 12.04 (or similar) install that I should try?
[19:35:29] <KimK> Any advice appreciated, and from anyone. Thanks, I'll check back.

Is he holding, perhaps not the source, but his "secret sauce" for ransom? A search did not find remaster in your UnifiedBuild link, also zero hits on the wiki. Sorry, I'm a little in the dark here. What I should learn from his frustration(?) and departure?

[21:26:11] <andypugh> However, it might effect us if we plan on making any more LiveCDs, and if remasterysys is the way that that is done.

[22:18:25] <andypugh> Ah, OK, I may have a relict webcam tab in that setup.
[22:18:44] <andypugh> This is a clean new build with a rather old config.
[22:19:49] <mhaberler> the topmost line in the trace file tells you where Python stalled; yes, remove the tab for now, probably will come up
[22:20:21] <andypugh> It will be failing to find camview-emc as it won't be on this new system.
[22:20:22] <mhaberler> does this run with master? we didnt touch anything UI related
[22:20:26] <mhaberler> ah
[22:23:35] <andypugh> And now it works. For levels of "work" which include a Resolver driver where raw-counts oscillate by several million revolutions every servo cycle...
[22:23:50] <andypugh> Which is the bug I built this system to fix
[22:24:12] <mhaberler> why dont you use gdb to poke into it
[22:24:27] <mhaberler> sudo gdb -p <pid of rtapi_app>
[22:24:37] <andypugh> I am pretty sure that I know exactly what the bug is.
[22:24:59] <mhaberler> ah, inner vision replacing debugging;)
[22:25:01] <andypugh> I just needed a real 64-bit system with real hardware to test it with.
[22:25:05] <skunkworks> oops.
[22:26:33] <mhaberler> I got me a N450 el-cheapo board to iron out the x86_64 peculiarities
[22:27:22] <skunkworks> how is the latency?
[22:27:59] <mhaberler> puh, I use it only as a build slave, but will have a look tomorrow
[22:28:41] <skunkworks> eh - don't go out of your way
[22:29:17] <mhaberler> I did not the 3.10-4rt-preempt kernel gives surprisingly good results, around 20/25us
[22:31:44] <skunkworks> wow
[22:32:20] <mhaberler> yes, a bit of a surprise, there's been a lot of work on rt-preempt
[22:32:40] <skunkworks> that would run stepping machines... (to a point)
[22:33:01] <skunkworks> Those little lathes we have are running a 50us base thread

[22:42:10] <andypugh> That resolves back to an include of <asm/types.h> ?
[22:43:34] <KimK> skunkworks: Hi Sam, re: my earlier posts (about what to new-install on E350N #2), do you have any advice for me beyond what I have received from andypugh, memleak, and ctbenergy?
[22:44:13] <skunkworks> no... :) I have not tried the new rtai build either

[22:46:21] <andypugh> Ah, I think I am reading it backwards....
[22:46:40] <andypugh> It's a typedef not a define.
[22:49:02] <KimK> skunkworks: It sounds like the new RTAI build should work, albeit with the ethernet hiccup. So absent any contrary advice from you, I'll give it a try. More news later.
[22:51:39] <andypugh> However, reading the notes in rtapi.h it seems to suggest that my habitual use of s32 and u32 is an error. Ought I to change them all to __s32 and __u32 etc?
[22:54:34] <CaptHindsight> 64bit RTAI is still a work in progress, might done in a few weeks
[22:57:45] <memleak> Paolo and I are working on unifying the architectures in RTAI, keeping as much code interchangeable between both 32 and 64
[22:58:30] <memleak> 64 is far behind but a lot of the 32-bit code is compatible with 64, but not entirely.
[22:58:57] <memleak> takes time to over which functions are and are not compatible.
[22:59:31] <memleak> RTAI math issues though are fixed in the master github branch in the ShabbyX tree for 32 and 64 architectures.
[22:59:39] <ctbenergy> KimK: E350N use the Realtek 8111E, you to not need to build the kernel module for Realtek 8168B

[23:00:22] <memleak> ctbenergy, for 8111E doesn't it use the 8169 driver?
[23:01:38] <memleak> 8168B with a 8169 driver causes issues interrupt issues but I personally haven't had any.. i'm pretty sure my board is a 8168 based controller.
[23:03:48] <memleak> If you need 64-bit RTAI support you'll need 2.6 based kernels (vulcano branch) I've tested it and it runs great.

[23:08:18] <mhaberler> andypugh: no, just use u<size>/s<size>
[23:08:33] <mhaberler> my mistake referring to __u8
[23:08:50] <ctbenergy> KimK: Oops! you are right, it use the same driver.
[23:08:57] <andypugh> Now I am confused.
[23:09:27] <andypugh> rtapi.h cleary states that you should use the __s<size> versions.
[23:10:18] <mhaberler> ok, I guess I should actually read it first..

[23:11:29] <mhaberler> the code and the comment dont agree
[23:11:30] <KimK> oops
[23:12:18] <mhaberler> the type name is u8 etc, via a reference to __u8 wherever that comes from, and that is what Charles uses in the code
[23:12:44] <mhaberler> eg here:

[23:14:20] <memleak> KimK, for the 3.4 debs (3.4.55) they are meant to be used with precise and they can be installed via dpkg -i
[23:15:12] <memleak> i.e. sudo dpkg -i <package>.deb
[23:15:42] <memleak> as for the exact order (as there is like 4 or 5 debs) i'm not sure but dpkg will tell you what you need to install something
[23:16:08] <andypugh> I think that someone who knows this for sure needs to take a look at the code.
[23:16:11] <CaptHindsight> KimK: before seb left he posted instructions on the dev mail list
[23:16:24] <andypugh> I see a disturbing number of casts to (long)
[23:16:33] <mhaberler> right, int userland the __u* typedefs come in via /usr/include/asm-generic/int-ll64.h

[23:29:59] <andypugh> Yes, what I menat was that some of my code didn't work at all.
[23:31:12] <andypugh> The apparent resolver position oscillates by millions of revs every servo cycle. That's a bit worse than a "math error" :-)

[23:38:13] <andypugh> Then I need to spin the spindle long enough to wrap 32 bits of revs. It won't take too long as the base-resolution is 24-bits.
[23:38:17] <mhaberler> better for what?

[23:39:52] <mhaberler> it would only be relevant if you hit 32bit limit. Not aware of such a case. In absence of that, it's just overhead
