*** MichaelWu has joined #mer06:59
davidqiUsually, the files are in the /srv/mer/sdks/sdk/tmp/ path07:00
davidqibut that directory of mine is empty07:00
kulveyou can create some kickstarts by:07:01
kulvesudo zypper install mer-kickstarter mer-kickstarter-configs07:01
kulvecd /usr/share/kickstarter-configs07:01
kulvemer-kickstarter -o /tmp/out-ks -c mer-reference-images/00reference.yaml07:01
kulvebut I don't remember if that includes those SDK kickstarts..07:02
zengweitottyhi, Kulve.07:05
zengweitottyI meet a problem. I transplanting Mer filesystem to S3C6410 board. My kernel can boot the filesystem that I create by myself.but I can not boot Mer fileSystem. kernel prints devtmpfs: mounted07:06
zengweitottyFreeing init memory: 168K07:06
zengweitottyKernel panic - not syncing: Attempted to kill init!07:06
*** zalan has quit IRC07:06
zengweitottyKulve, Could you help me about this problem? thank you very very much07:07
chriadam|busyyep07:08
chriadam|busygrargh.  wrong window07:08
kulveunfortunately I can't remember why that error would be happening..07:08
zengweitottyhi chriadam. could you make it more clearly07:09
kulvezengweitotty: did you create the mer filesystem yourself?07:09
chriadam|busyzengweitotty: sorry, I don't know what causes that either.  I just accidentally pressed "up + enter" while focus was on my IRC client, instead of my terminal ;-)07:10
chriadam|busyand apparently "yep" was the last thing I said.07:10
Stskeepszengweitotty: are you using mer armv6 port?07:10
zengweitottyhi Stskeeps. yes07:10
zengweitottyI think the problem is my kernel config07:11
Stskeepszengweitotty: kernel version?07:11
zengweitottyMy kernel version is linux-3.0.107:11
kulvezengweitotty: make sure your kernel config matches these: https://github.com/lbt/mer-kernel-check/blob/master/mer_verify_kernel_config#L12807:12
zengweitottycan Mer do not match some other kernel version07:12
kulvezengweitotty: also make sure your rootfs really is ARMv6 and not ARMv707:12
zengweitottyyes ,I do07:13
zengweitottyKulve,I checked my kernel config as the link says last night07:14
*** plfiorini has quit IRC07:14
zengweitottybut The problem still has07:14
Stskeepszengweitotty: how do you make your image? mic cr -A armv6l ?07:14
zengweitottyyes07:14
Stskeepshmm07:15
davidqithanks Kulve07:16
davidqiI have recreated them.07:16
zengweitottyStskeeps,is there any another important things I might miss07:17
Stskeepszengweitotty: does init=/bin/sh work?07:18
Stskeepsas command line07:18
zengweitottyset bootargs "noinitrd root=179:2 rw init=/bin/bash console=ttySAC0,115200"07:19
zengweitottythis is my command line args07:19
Stskeepsok, and it doesn't work?07:19
Stskeepscan you readelf -A bin/bash    on your root filesystem?07:20
zengweitottyset bootargs "noinitrd root=179:2 rw init=/sbin/init console=ttySAC0,115200"07:20
Stskeepsjust to be sure07:20

Stskeepsyou may have to use mer/rootme10:59
Stskeepsand then su to root10:59
lbtdavidqi: OK, I updated the wiki to prevent other people hitting that - I think it relies on users having run mic in the host at some point11:00
zengweitottyhi, Stskeeps, thank you for your help11:01

zengweitottyand how Can I run GUI11:01
Stskeepszengweitotty: you can maybe try to install xorg with fbdev and qmlviewer11:01
lbtdavidqi: well, you had to manually make  /parentroot/var/tmp/mic/cache - mic would have done that11:02
zengweitottyStill I can not see the Qt logo on touchScreen11:02
lbtin the SDK /parentroot is a bind mount to 'outside' the SDK11:02
Stskeepszengweitotty: what .ks did you use?11:02

*** merder has quit IRC18:39
shmerlbtw, I spoke to some VP8 folks, and they said that libvpx is software decoding (though it can use Neon if available).18:40
shmerlSo for anything to use hardware decoding - will require to use vendor provided APIs and such18:41
Stskeepsmakes sense18:41
Stskeepsthat's why you have stuff like gst :P18:41
*** faenil has quit IRC18:41
shmerlWell, gst uses the same libvpx underneath for VP8 (unless you provide some other backend)18:42
Stskeepssure18:42
shmerlAlso they said that their own wiki is misleading.18:43
shmerlAnd for example tegra3 most likely doesn't have hardware decoding.18:44
shmerlSo to package libvpx I don't think you need any specific configuration for each target and it might work OK to package it generically in Mer for each arch.18:44
Stskeepsis there any good analysis on the legal situation revolving it?18:45
shmerlI doubt you can ever get a "good" analysis in a sense of 100% security from trolls.18:45
shmerlSo far there are no known patents asserted against it (if that's what you mean)18:46
shmerlGoogle has legal statement about the licensing (that's it's free)18:47

shmerlIt's also free, but there are 2 claims of patents against it, though in this case the patents are known and according to opus devs they are not applicable.18:51

[ol]Stskeeps: Do you remember how you were building libtool for ARM architecture?19:47
Stskeepsthat one really should be easy19:47
Stskeepswhere are you at by now?19:47
*** thopiekar has joined #mer19:48
[ol]Stskeeps: That's easy, but later other packages built with this easy libtool have problems with rpath pointing to /opt/cross.19:49
Stskeepsthat rings a bell..19:49
[ol]Stskeeps: I was busy last week, but now when Christmas approaching it's quiet time, so I've made some progress.19:49
Stskeeps[ol]: was this built with sb2?19:50
[ol]Stskeeps: Yes, that rings the bell: configure from libtool dist takes libraries from compiler flags, and sb2 uses native cross-compiler.19:51
*** tilgovi has joined #mer19:51
Stskeepsnow i'm actually wondering if there's a problem in mer's libtool19:51
Stskeepslet me just check something19:52
*** yashshah has quit IRC19:52
[ol]Stskeeps: There's no problem with libtool in SDK.19:53
Stskeepsyeah, but on arm targets19:53
[ol]You can just diff /usr/bin/libtool from SDK with the one for target.19:53
*** cristi has joined #mer19:54
[ol]There are not so much different lines.19:54
Stskeepsso, the reason why this rings a bell is that as part of the sb2 enablement for mer, i did comparisons between our old approach and our new approach (sb2 one)19:54
Stskeepsie, down to package contents19:54
Stskeepsare you talking about sys_lib_search_path_spec="/opt/cross/lib/gcc/armv7l-meego-linux-gnueabi/4.6.4 /opt/cross/armv7l-meego-linux-gnueabi/lib /lib /usr/lib "19:55
Stskeeps ?19:55
[ol]Stskeeps: Yes, exactly.19:55
Stskeepsokay, give me an example of where this ends up in a binary?19:56
*** jstaniek has joined #mer19:58
[ol]Stskeeps: I've found that when libtool builds C++ shared libraries, it runs g++ with "-Wl,-rpath -Wl,/opt/cross/x86_64-meego-linux-gnu/lib/../lib" options. I've encountered this with libdb_cxx from db4 and with libasprintf from gettext.19:59
*** Sfiet_Konstantin has joined #mer20:01
Stskeepsokay, that doesn't sound good to me20:04
Stskeepsand the rpath ends up in the actual binary?20:04
*** spangles has quit IRC20:06
[ol]Stskeeps: Yes. But it leads to error in "/usr/lib/rpm/check-rpaths" which aborts packaging.20:07
Stskeepsthat's weird, why doesn't that happen on arm..20:07
[ol]So far I'm trying to find configure args which make it to use specified compiler flags, not ones autodetected from compiler's verbose output. But if I fail, there's another way: to post-process libtool program after buld.20:09
Stskeeps[ol]: show me the sb2-init output for your target?20:10
*** faenil has joined #mer20:11
[ol]I did sb2-init several reboots ago, so I don't have its output. But I have the flags used in my sb2 config.20:11
[ol]SBOX_INIT_ORIG_ARGS="-d -L --sysroot=/ -C --sysroot=/ -m sdk-build -n -N -t / mer-core /opt/cross/bin/x86_64-meego-linux-gnu-gcc"20:11
Stskeepsokay20:11
Stskeepsthere goes my first hunch, hmm20:12
[ol]OK, so there's a difference how sb2 works for x86_64 target and arm target.20:12
*** notmart has quit IRC20:15
*** pohly has joined #mer20:15
*** phaeron has joined #mer20:15
Stskeepsyeah, i'm not getting those rpath errors, but the libtool is definately talking about /opt/cross20:17
Stskeepsand i compile db4 too there20:18
[ol]I've found that some of my fixes to sb2 are wrong because I didn't understand correctly how it works. It appears that treating x86_64 binaries on i386 host as host-native was not a bug. It treats x86_64 as host-compatible target and needs no cputransparency emulation, but it uses a directory the binary is located on to find whether it's for host or for target. In case of target binary it tries to load libsb2.so.1 installed in target root. So I've made it work by20:19
[ol]removing a couple of my patches, and built and installed libsb2 for x86_64 target.20:19
[ol]That's how I've made sb2 to build packages.20:19
*** rodrigo_golive has quit IRC20:21
*** disco_stu_droid has joined #mer20:21
[ol]But I think that accelerated build (using cross-compiler build on host instead of target native compiler) is not much different in whether cputransparency is configured or not.20:21

[ol]So far I've built and installed the following packages: m4, gdbm, perl (needs libperl.so placed in /usr/lib to work), autoconf, automake, libtool (still has issues), db4 (db4-cxx has problems with rpath), zlib, pkgconfig, ncurses, texinfo, bison, expat.20:27
[ol]In this order.20:27
Stskeeps:nod:20:27
[ol]There were a couple of funny problems when building perl.20:28

*** SfietKonstantin has joined #mer20:29
[ol]Perl build was failing because its Cwd module uses reverse path traversal until root to find current directory (or any file's absulute path). It didn't work for my homedir because emulated root didn't have "/home".20:29
*** Jake9xx_ has joined #mer20:30
[ol]Creating an empty "home" dir inside target root is a working workaround.20:30
Stskeepsemulated root.. as in -R ?20:30

[ol]No, emulated root directory.,20:30

[ol]When sb2 treats target binaries as host-compatible, it uses binary's path to determine whether it's host or target one. And it was thinking that anything in "/home" has exec policy "Tools", not "Target".20:36
Stskeepsah..20:36
[ol]Changing the order of entries of exec_policy_selection in "/usr/share/scratchbox2/modes/sdk-build/config.lua" file ("dir = sbox_user_home_dir ..." to come before "prefix = tools_root ...") solved this problem.20:37
Stskeepsok20:37
*** pvanhoof_ is now known as pvanhoof20:37
[ol]So, here's the question: What sb2-init "-t /" means?20:38
Stskeepsmeans that the tools is the / directory20:38
[ol]I mean, what "-t /" option means?20:38
Stskeepsi -think- you can remove it20:38
[ol]What tools?20:38
Stskeepsok, so20:38
Stskeepsit's possible to have for example debian as the host os, and then /mer is the tools where it gets the tools for cross compilation20:39
Stskeepsif it causes problems, try ditching the -t /20:39

[ol]So, there's a patch for zlib which makes it use some accelerated CPU asembly language functions on popular architectures.21:02
[ol]This patch is applied to zlib when building an RPM.21:02
[ol]And as a result, RPM build fails on x86_64 with assembler complaining that some label is defined twice.21:03
[ol]But this label is defined just once in asm directive inside some function accelerated for SSE3.21:04
[ol]But it appears twice in .s file (if compiled with "-S" option).21:05
*** SfietKonstantin has quit IRC21:05
[ol]But it apperrs just once in .s file after changing "-O2" compiler flag to "-O3".21:05
Stskeeps[ol]: yeah, we see bizarre issues like that on arm too on occasion21:06
Stskeepsi think it's a gcc or assembler bug21:06
Stskeepsjust disable the patch for bootstrap21:06
[ol]So, for some reason unknown to me, gcc optimises code and inlines a part of that function twice.21:06
[ol]Marking this function with __attribute__((__noinline__, __noclone__)) doesn't help.21:07
Stskeeps:nod:21:07
Stskeepshence the bug thing21:07
[ol]But the very beginning of the patch contains the line: "Generated by cloneing https://github.com/kaffeemonster/zlib/commits/adler32_vec and merging v1.2.7 into it."21:08
Stskeepsright21:09
[ol]So, here's the solution: using the new version of the same file from github and embedding it into the patch!21:09
[ol]It did the trick.21:09
Stskeepswow, i did this back in may?21:10
Stskeeps[ol]: contribution welcome to fix :P21:10
