Apr 30 13:03:31 <chouimat|work> morning
Apr 30 17:45:31 <cheshair> hi all of guys!
Apr 30 19:43:55 <cheshair> could you kindly tell me if i can build applications for my arm9 target by means of the open source version of qt/embedded?
Apr 30 19:46:18 <ljp> yes
Apr 30 19:51:41 <cheshair> ljp: thank you very much
Apr 30 19:52:39 <ljp> no worries
Apr 30 19:54:11 <cheshair> ljp: you should be worried: i'll come back in a while with a good deal of questions :-D
Apr 30 19:55:06 <ljp> no worries, I am heading for Hawaii today for two weeks
Apr 30 19:55:38 <cheshair> that's good! where do you come from?
Apr 30 19:56:00 <ljp> originally?
Apr 30 19:56:16 <ljp> i am from the us living in australia
Apr 30 19:56:23 <cheshair> i see
Apr 30 19:56:38 <cheshair> working in the it area?
Apr 30 19:57:01 <ljp> nope. my parents own a time share condo near waikiki beach.
Apr 30 19:57:38 <cheshair> that's real luck! :-)
Apr 30 19:57:57 <ljp> naaa. strategy :)
Apr 30 19:58:24 <cheshair> eh eh :-) i hope you'll enjoy your stay and surf big waves
Apr 30 19:59:20 <ljp> ok. i will try
Apr 30 20:00:00 <cheshair> ljp: i downloaded, configured and compiled this source: qtopia-core-opensource-src-4.3.3.tar.gz
Apr 30 20:00:32 <chouimat|work> ljp: have fun and enjoy your vacations :)
Apr 30 20:00:51 <cheshair> is that enough to build applications for my arm9 devices?
Apr 30 20:01:14 <ljp> chouimat|work: thanks. i will
Apr 30 20:01:21 <cheshair> (i also have qvfb from debian repos)
Apr 30 20:01:30 <ljp> cheshair: as long as you have the proper toolchain
Apr 30 20:01:34 <chouimat|work> ljp: I doubt I will be able to take any vacations before november 
Apr 30 20:02:20 <cheshair> ljp: i have a normal toolchain, the one i usually use to crosscompile things from my pc to my arm9 devices
Apr 30 20:02:49 <cheshair> ljp: "normal" toolchain... i mean... a toolchain not related to qt
Apr 30 20:04:27 <ljp> yep. you should be good to go!
Apr 30 20:04:33 <cheshair> ljp: to build qtopia i typed "./configured -qvfb -prefix /my/path" without "-embedded arm": was i wrong?
Apr 30 20:05:41 <ljp> probably
Apr 30 20:05:56 <ljp> might also need to set -xplatform
Apr 30 20:06:18 <cheshair> i see
Apr 30 20:07:06 <cheshair> so i'll add -embedded and -xplatform
Apr 30 20:11:28 <cheshair> ljp: could you be so kind and patient to give me some hint with regard to the cross compilation? given that i have my qtopia properly installed (with -embedded etc), how do i crosscompile my code?
Apr 30 20:21:13 <cheshair> in order to build qtopia, i'm told to run "./configure -embedded [architecture]". i don't know whether using "arm" or "x86"... (qtopia will run on my x86 pc, but i will use it to generate arm binaries...)
Apr 30 20:34:01 <ljp> if your target is arm you must tell it that.
Apr 30 20:34:08 <ljp> sorry, but I must go now. 
Apr 30 20:34:22 <cheshair> hi ljp
Apr 30 20:34:41 <cheshair> you've been so helpful, thank you!
Apr 30 20:34:45 <chouimat|work> ljp_hawaii: have fun
Apr 30 20:34:51 <cheshair> and good vacations!
Apr 30 20:35:30 <cheshair> guys, did i miss something while my connection was down?
Apr 30 20:39:12 <cheshair> i only got "ljp: if your target is arm you must tell it that.", because i had a system failure
Apr 30 21:00:53 <cheshair> hi guys: this file seems to be from 2006 http://doc.trolltech.com/qtopia4.1/new-user-guide.html ... should i rely on it or look for somenew stuff?
Apr 30 21:18:57 <rohanpm> cheshair: http://doc.trolltech.com/qtopia4.3-snapshot/building-guide.html
Apr 30 21:19:44 <cheshair> rohanpm: thank you very much
Apr 30 21:21:33 <cheshair> rohanpm: could you shed some light on terminology? what's the difference between qt/embedded, qtopia and qtopia phone and what am i supposed to build or deal with (given that i need to build arm applications on my x86 pc)
Apr 30 21:22:18 <rohanpm> cheshair: qt/embedded is just another platform for Qt, like Qt/X11, Qt for OSX or Qt for Windows
Apr 30 21:23:45 <rohanpm> cheshair: Qtopia is a whole bunch of libraries, applications and services for embedded (mostly phone-like) devices, originally built on top of Qt/Embedded (but much of it now works on any Qt platform)
Apr 30 21:24:15 <cheshair> rohanpm: i see
Apr 30 21:24:30 <rohanpm> cheshair: Qtopia Phone is the edition of Qtopia intended for use on phones, which happens to be the most maintained and featureful edition
Apr 30 21:25:39 <cheshair> rohanpm: i just wish to become acquainted with qt by building a very simple app for an arm9 device i own
Apr 30 21:25:52 <cheshair> rohanpm: what's your advice?
Apr 30 21:25:54 <rohanpm> cheshair: probably start with Qt/Embedded then
Apr 30 21:26:00 <cheshair> ok
Apr 30 21:27:28 <cheshair> rohanpm: when you say "qt/embedded is just another platform" you mean qt/embedded will be placed as an underlying layer on my arm device with qt applications over it? or i'll just manage to build "stand-alone" qt application and let them run on my arm linux system?
Apr 30 21:28:58 <cheshair> rohanpm: not to bother you too much: the link you pointed is the right starting point for qt/embedded? or is it qtopia specific?
Apr 30 21:29:19 <rohanpm> cheshair: qt/embedded is just a bunch of libraries like qt/x11.  The difference is that the "window manager" is implemented in qt/embedded itself.  But your app will still be standalone... it just happens to manage the display as well.
Apr 30 21:29:39 <rohanpm> If you have more than one app running, then one of them acts as the window manager.
Apr 30 21:29:47 <rohanpm> cheshair: that link is Qtopia specific
Apr 30 21:30:23 <cheshair> rohanpm: i see, that's very interesting
Apr 30 21:30:48 <rohanpm> cheshair: try: http://doc.trolltech.com/4.4/qt-embedded.html
Apr 30 21:31:22 <cheshair> and you're so enlightening
Apr 30 21:32:01 <rohanpm> I only understand this stuff because I work in a building surrounded by dozens of Qtopia developers :-)
Apr 30 21:32:23 <cheshair> nice place to live! :-)
Apr 30 21:32:25 <rohanpm> Took me a while to get to grips with what Qtopia really is myself
Apr 30 21:32:31 <cheshair> where do you live?
Apr 30 21:32:42 <cheshair> norway?
Apr 30 21:32:45 <rohanpm> Brisbane, Australia
Apr 30 21:32:51 <cheshair> i see
Apr 30 21:32:56 <rohanpm> That's where Qtopia (not Qt Embedded) is developed
Apr 30 21:33:39 <cheshair> rohanpm: also ljp is from australia, he was of a big help an hour ago 
Apr 30 21:34:18 <cheshair> rohanpm: what in the world keeps you far from beaches and waves?
Apr 30 21:34:20 <cheshair> :-)
Apr 30 21:34:28 <rohanpm> I know, when he's not on vacation he's working a few rooms away :-)
Apr 30 21:36:16 <cheshair> "Qtopia is a whole bunch of libraries" ... so i get libraries for gsm comunication or for my gps or stuff like that in it?
Apr 30 21:37:23 <rohanpm> Well, sort of.  Some of that stuff comes from third parties, since it may be device-specific or patent encumbered
Apr 30 21:38:01 <cheshair> i see
Apr 30 21:41:20 <cheshair> today i was working on qt/embedded. i was trying to configure and install it. first trouble: "./configure -embedded [architecture]" which arch if i want to build on my x86 pc for arm devices? have i got to specify also -platform and -xplatform?
Apr 30 21:42:35 <cheshair> on the trolltech docs i read "In general, all Linux systems which have framebuffer support can use the generic architecture."
Apr 30 21:42:55 <cheshair> so generic is ok even if i'll build arm apps?
Apr 30 21:43:22 <rohanpm> Here is an example configure line:
Apr 30 21:44:27 <rohanpm> ~/qt_source/configure -embedded arm -platform linux-g++ -xplatform ~/qt_source/mkspecs/qws/linux-arm-g++
Apr 30 21:45:04 <cheshair> veeery interesting
Apr 30 21:47:04 * rohanpm gets ready to leave for work
Apr 30 21:47:17 <cheshair> rohanpm: you have been of such a big help
Apr 30 21:47:45 <cheshair> rohanpm: i hope i'll meet you again on line
Apr 30 22:24:09 <cheshair> when compiling qtopia-core-opensource-src-4.3.3 with
Apr 30 22:24:09 <cheshair> $ ./configure -embedded arm -platform linux-g++ -xplatform mkspecs/qws/linux-arm-g++ -prefix /home/user/local -big-endian
Apr 30 22:24:09 <cheshair> $ make
Apr 30 22:24:09 <cheshair> i get
Apr 30 22:24:09 <cheshair> make: *** [sub-corelib-make_default-ordered] Error 2
Apr 30 22:24:10 <cheshair> because
Apr 30 22:24:12 <cheshair> make[1]: Makefile: No such file or directory
Apr 30 22:24:28 <cheshair> any hints on this?
