| zzarr | hello! | 10:29 |
|---|---|---|
| zzarr | if there is a Vulkan driver for a GPU, would that matter to MIR (could I get MIR running with the help of it in the future?) | 10:46 |

| suebt | Hey there, I'm trying to get kivy (https://kivy.org/) running on Ubuntu Touch. The Python stuff part is working but I have issues with SDL and (maybe) MIR. It would be super cool if you could look into this whether you have an idea what's causing the error. | 13:00 |
| suebt | So, the program is starting and segfaulting when loading sdl | 13:01 |
| anpok_ | sdl2 that is? | 13:01 |
| suebt | yes | 13:01 |
| anpok_ | what sdl2 library are you using | 13:02 |
| suebt | Custom builds (SDL2-2.0.4) | 13:02 |
| anpok_ | hm bschaeffer is not around | 13:02 |
| suebt | I tried with packaged versions as well. | 13:02 |
| suebt | Both resulting to the same error | 13:02 |
| anpok_ | he would know better.. the symptoms sound familiar | 13:03 |
| suebt | okay, thanks, I'll just drop some links to the logs in case they're useful? | 13:03 |
| suebt | https://drive.google.com/folderview?id=0B4EyY4wSGSyjNWwzVGo1eHBUc1k&usp=sharing Here are some stack traces. "kivy_log" is the output from python. | 13:05 |
| === alan_g|lunch is now known as alan_g | ||
| greyback | suebt: hey, those are "syscall traces" - you used strace, right? That tool reports all the calls the app makes to the kernel. This doc shows how to get stacktraces: https://wiki.ubuntu.com/Backtrace which would help us more | 13:13 |
| suebt | greyback: okay, thanks. Yes, those where strace logs. Here is a gdb log: https://drive.google.com/folderview?id=0B4EyY4wSGSyjMFhlRDh6V2NrNjg&usp=sharing | 13:19 |
| suebt | or better http://paste.ubuntu.com/15551628/ | 13:20 |
| greyback | suebt: ok, looking, it's not a useful backtrace, as you only have 2 frames of the stack. __GI_raise indicates an exception was thrown. | 13:21 |
| suebt | hmm, is there anything I can do to provide more useful information about this? | 13:22 |
| greyback | suebt: suggest you install the debug packages for mir, and libc6-dbg, and then try again | 13:22 |
| suebt | okay, libc6-dbg is installed. Will install mir debug packages | 13:23 |
| greyback | suebt: in gdb, also do "catch throw" before running | 13:23 |
| suebt | okay, will do, thanks! | 13:23 |
| greyback | thank you | 13:23 |
| suebt | greyback: can you possibly point me on which mir debug packages you mean? | 13:25 |
| greyback | suebt: probably libmirclient9-dbgsym | 13:27 |
| suebt | greyback okay, thanks, let's see... | 13:28 |
| suebt | Hmm... it's not in vivid repos, is there a ppa for it? | 13:39 |
| greyback | suebt: you probably need this: https://wiki.ubuntu.com/DebuggingProgramCrash#Non-built-in_debug_symbol_packages_.28.2A-dbgsym.29 | 13:44 |
| suebt | greyback: It throws a lot of "W: Failed to fetch ..." errors if I try this … | 13:51 |
| greyback | suebt: can you pastebin me what you see and the commands you used? | 13:52 |
| greyback | and also the contents of /etc/apt/sources.list.d/ddebs.list | 13:53 |
| suebt | greyback: This is what I did: http://paste.ubuntu.com/15551845/ and here is my /etc/apt/sources.list.d/ddebs.list: http://paste.ubuntu.com/15551853/ | 13:55 |
| greyback | suebt: oh, you're working on the phone | 13:56 |
| suebt | yeah sure :) | 13:56 |
| greyback | suebt: ok, I need to change the advice (sorry, I thought you were developing on your desktop) | 13:56 |
| suebt | oh np :) | 13:56 |
| suebt | I don't have mir on the desktop | 13:57 |
| greyback | suebt: please edit the ddebs.list file to just contain this: | 13:57 |
| greyback | deb http://ppa.launchpad.net/ci-train-ppa-service/stable-phone-overlay/ubuntu vivid main/debug | 13:57 |
| suebt | okay | 13:57 |
| suebt | (I'm on rc-proposed tho, not sure if that changes something) | 13:57 |
| greyback | explanation: the phone uses a PPA to deliver software newer than vivid (which is about a year old now). So you need a special place to find debug packages for that PPA (which is what I gave you) | 13:58 |
| greyback | suebt: nah, perfect. Best place for developing | 13:59 |
| suebt | ah okay :) | 13:59 |
| suebt | meh it doesn't want to write to that file oO | 13:59 |
| greyback | I think you're nearly out of disk space too | 13:59 |
| suebt | yep xD | 14:00 |
| suebt | nano doesn't work properly ... Or is it normal i can't save that file? | 14:00 |
| greyback | are you root? | 14:01 |
| suebt | I am. | 14:01 |
| greyback | I suspect nano and "adb shell" don't work well together | 14:01 |
| greyback | the return key seems to disappear | 14:02 |
| suebt | yeah, I'll move the file manually ... | 14:02 |
| greyback | delete it and do | 14:02 |
| greyback | echo "deb http://ppa.launchpad.net/ci-train-ppa-service/stable-phone-overlay/ubuntu vivid main/debug" | sudo tee -a /etc/apt/sources.list.d/ddebs.list | 14:02 |
| suebt | oh that would've been faster :) | 14:03 |
| suebt | done | 14:03 |
| greyback | now after apt update you should be able to find the mir debug packages | 14:04 |
| suebt | phablet@ubuntu-phablet:~/Documents$ sudo apt-cache policy libmirclient | 14:05 |
| suebt | E: Write error - write (28: No space left on device) | 14:05 |
| suebt | ha /0\ | 14:06 |
| greyback | sudo apt-get clean | 14:06 |
| greyback | might help | 14:06 |
| suebt | done, took a second to run :) | 14:07 |
| suebt | will delete some picture | 14:07 |
| suebt | *s | 14:07 |
| suebt | meh, still no space left | 14:08 |
| suebt | Think, I'd better do a clean reset, should I? | 14:08 |
| greyback | suebt: from experience, you'll hit this again & again | 14:16 |
| greyback | you'd be better developing in a chroot. Let me try find a link to a handy email | 14:17 |
| suebt | greyback: Okay, that'd be super nice :) | 14:20 |
| greyback | suebt: http://pastebin.ubuntu.com/15552039/ | 14:24 |
| greyback | oh, "sagu" should be "sudo apt update" | 14:25 |
| greyback | oh, "sagy" should be "sudo apt install" | 14:25 |
| suebt | greyback: really nice, thanks, I'll look into it. Just finish resetting my device up ... | 14:26 |
| greyback | suebt: fixed: http://pastebin.ubuntu.com/15552049/ | 14:26 |
| greyback | http://pastebin.ubuntu.com/15552056/ | 14:26 |
| greyback | is better | 14:27 |
| suebt | greyback: cool, I'm back (with a fresh ubuntu phone)! | 14:57 |
| suebt | So this is to be setup on the phone? | 14:57 |
| suebt | I'll try | 14:57 |
| greyback | suebt: let's see | 14:58 |
| suebt | hah, need to enable developer mode first :) | 14:59 |
| suebt | whut? "E: Write error - write (28: No space left on device)" | 15:05 |
| suebt | What does this "reset" actually do xD ... let me reflash | 15:05 |

| camako | zzarr, hi | 15:12 |
| camako | zzarr, do you have source access to the GPU driver you've mentioned? | 15:13 |
| camako | zzarr, you'd need to implement the Window System Integration extensions to be able to display | 15:14 |
| camako | WSI extensions for Mir, that is... using the Mir client library. | 15:14 |
| camako | We have not officially published all the headers you'd need. | 15:15 |
| camako | But they are available in our dev trunk | 15:15 |

| suebt | greyback: had to go off for some time. "sudo apt install debootstrap" doesn't work, I assume I should add the universe repo? | 18:22 |
| greyback | suebt: did you "apt update" first? | 18:23 |
| suebt | greyback no, will try | 18:24 |
| suebt | greyback: oh, it works now, thank you! | 18:25 |
| greyback | np | 18:25 |
| suebt | greyback: hhmm, I get "usermod -G sudo phablet" >> "usermod: user 'phablet' does not exist" | 18:40 |
| suebt | "sudo ./ch -r vivid-chroot/" >> "logname: no login name | 18:41 |
| suebt | logname: no login name" | 18:41 |
| greyback | suebt: what is the user of your chroot? "echo $USER" | 18:41 |
| suebt | "echo $USER root" | 18:41 |
| suebt | "echo $USER" >> "root" | 18:41 |
| greyback | suebt: if you enter the chroot as not-root, i.e. remove the "-r" switch, what is the user? | 18:42 |
| suebt | still root ... | 18:42 |
| suebt | without -r | 18:42 |
| greyback | oh, you were root when creating the chroot, weren't you? | 18:44 |
| suebt | hmm yeah, cause of sudo? | 18:44 |
| greyback | even before? | 18:45 |
| suebt | "echo $USER" > phablet -> outside of my chroot. At least now ... | 18:45 |
| greyback | ok, that's good | 18:45 |
| suebt | Does this matter? | 18:46 |
| greyback | not hugely | 18:46 |
| suebt | it also says "mount: mount point /home/phablet/vivid-chroot//home/phablet does not exist" | 18:46 |
| greyback | I'm not sure what's gone wrong. debootstrap should know about the phablet user. | 18:48 |
| suebt | can't I create it manuallyß | 18:49 |
| suebt | *? | 18:49 |
| greyback | yeah, you can | 18:49 |
| greyback | I just never have to | 18:49 |
| greyback | so I'm confused what is different | 18:50 |
| suebt | maybe I did something wrong? | 18:50 |
| * suebt double checks everything | 18:50 | |
| greyback | suebt: fyi, you can blow everything away by just deleting the $HOME/vivid-chroot directory | 18:51 |
| suebt | ok | 18:51 |
| suebt | but I think I did it exactly the same | 18:51 |
| suebt | let me try again | 18:51 |
| greyback | suebt: only difference I can think of is that usually I SSH into the device. I find adb shell sometimes causes me problems | 18:51 |
| greyback | but the instructions I gave you are exactly those I follow | 18:52 |
| suebt | Ah, okay, I can try to use ssh | 18:52 |
| === dandrader is now known as dandrader|afk | ||
| suebt | adb seems to be the issue indeed! No errors via ssh, yet | 19:10 |
| * suebt needs to go off for today soon tho, thanks for all your help, will continue tomorrow. | 19:10 | |
