08:40 < tri> hi rxr
08:40 < tri> (07:59:54) tri: i have problems building cdrkit
08:40 < tri> (08:00:15) tri: Found shared files with outher packages:
08:42 < tri> (08:00:52) tri: ...cdda2ogg.1: cdrkit cdrtools and cdrecord.1: cdrkit cdrtools - how to solve this ?
08:43 < rxr> ah, I thought you already "read this" solution
08:43 < rxr> http://www.t2-project.org/handbook/html/t2.build.troubleshooting.html#t2.build.troubleshooting.shared-files
08:44 < tri> ok but where is the solution ?
08:44 < rxr> in this case deseelect of of them
08:44 < rxr> I would go for the moder, dvd writing cdrkit
08:45 < rxr> do you build a own selection? or are both of the packages selected in some predefined T2 selection ?
08:47 < CIA-9> rene * r24159 /trunk/package/x86/powertop/powertop.desc: * updated powertop (1.1 -> 1.2)
08:47 -!- write_erase [n=olivier@bon13-2-82-237-125-220.fbx.proxad.net] has quit ["Leaving"]
08:49 < tri> ah so i should deselect cdrtools ? i have my own config with the predefined t2 selection "basic desktop"
08:53 < CIA-9> rene * r24160 /trunk/target/generic/pkgsel/00-minimal.in: * exchanged cdrtools with cdrkit in the 00-minimal selection
08:58 < tri> ah ok
08:59 < tri> i uninstalled cdrtools with mine and now i was able to emerge-pkg cdrkit without problems
08:59 < tri> thx
09:04 < tri> i which package is mkisofs ?
09:04 < tri> ^/i/in
09:07 < rxr> huestel, cdrtools has it, but cdrkit should do a compat link
09:07 < rxr> cdrkit names it genisofs

09:30 < tri> i just found genisoimage - if i try to use "Create-Iso" it wants the mkisofs - should i just create a symlink ?
09:34 < rxr> quick fix: yes
09:34 < rxr> real fix: we should improve Create-ISO to search for one of them :-)
09:36 < rxr> I work on the real fix right now
09:42 < CIA-9> rene * r24163 /trunk/scripts/Create-ISO: * improved Create-ISO to search for a compatible "mkisofs", currently either mkisofs or genisoimage
09:42 < rxr> ^- date to test?
09:45 < CIA-9> susan * r24164 /trunk/package/gnome2/bluez-gnome/bluez-gnome.desc: * updated bluez-gnome (0.6 -> 0.7)

14:18 < rxr> sepp: I pulled the gcc xorg-server (and other's) related backport
14:19 < rxr> while the last time xorg-server built on the reference builder, this time I stopped it after building from 7:00 till now
14:21 < sepp> gcc crashed my box with latest xorg 1st (with 2 jobs) with 1 i gave up after 2h on *pci.c
14:21 < sepp> used -O0 ...
14:22 < sepp> with 2 jobs it was trashing swap like mad and i was unable to get to vc1 and kill it
14:22 < rxr> http://mac360.com/index.php/mac360/comments/did_apple_steal_the_iphone_design_from_lg/
14:22 < rxr> sepp: did you try that patch ?
14:22 < sepp> no :/
14:22 < sepp> used -O0
14:22 < rxr> ok - I pulled the patch and checking
14:22 < sepp> :)
14:23 < sepp> hope it does not cause new regressions
14:25 < sepp> when gcc builds objective it is just some runtime library?
14:26 < sepp> objective c
14:26 < rxr> hm?
14:26 < rxr> objective c has two parts, compiler and runtime
14:27 < CIA-9> rene * r24168 /trunk/package/network/pound/pound.desc: * updated pound (2.3.1 -> 2.3.2)
14:27 < sepp> ok
14:28 < sepp> is there anything beside gnustep that needs objc ?
14:29 < rxr> some opengroupware and some other fun toys
14:29 < rxr> of course all the old NeXT applications and when you want to port Mac applications to Linux or so
14:30 < sepp> i think i will disable that next time :p

15:56 < babygor> ¡buenos días! (good morning!)
15:56 < sepp> hi babygor, write_erase :)
15:57 < babygor> this question should be simple, how do I force a particular gcc version
15:57 < babygor> to be used?
15:57 < babygor> 4.2 is too-bleeding-edge for me :-)
15:58 < write_erase> hi sepp babygor
15:59 < rxr> write_erase: as I noted I only have the STK1000 here
16:00 < rxr> our prototypes always run completey from the SD
16:00 < rxr> so there is no way to damaage the board and the progress can be versioned as SD snapshots or just moving the SD cards around
16:00 < rxr> babygor: use the 6.0 version
16:00 < rxr> T2-6.0 is about gcc-4.2.x and glibc-2.5
16:01 < write_erase> rxr, fine ... Should be the same for my board
16:01 < rxr> while trunk will soon be branched as gcc-4.2 and glibc-2.6
16:03 < write_erase> rxr, Where are the informations for preparing the SD card, and force boot on it ?
16:03 < write_erase> Is that on avrfreak's wiki ?
16:03 < babygor> ok, thanks!

17:22 < jalsot> hi
17:22 < jalsot> does anybody know what are the main differences between T2 and buildroot [maybe others like OpenEmbedded]?
17:24 < rxr> the main difference is that the T2 code base was the first in the game, created in 1998
17:25 < rxr> and the most portable, generic one and most easy to use
17:25 < rxr> in particular I find OpenEmbedded a PITA to use
17:25 < rxr> http://www.t2-project.org/faq/
17:25 < jalsot> I have some experience with buildroot - on x86, but now I need Blackfin support
17:25 < jalsot> and as I saw, T2 has it :)
17:25 < rxr> .oO
17:26 < jalsot> thx, will look for the FAQ :)
17:26 < rxr> I guess I should hurry commit all the pending local blackfin bits ...
17:26 < jalsot> oh, you are the bfin guy? :)
17:26 < rxr> yeah
17:26 < jalsot> which toolchain do you use in T2?
17:26 < rxr> gcc-4.x + patches
17:27 < rxr> the vanilly gcc has bfin but misses some "state of the art" bits to support the new shared object format commonly used
17:27 < rxr> so current uclibc versions only build with a patched gcc
17:28 < jalsot> wow
17:28 < rxr> in how many hours do you need T2 bfin support? I have quite some pending local changes that need to be added for final support
17:28 < jalsot> so T2 may be a good choice for me?
17:29 < rxr> someone except http://ExactCode.de needing bfin kinda is a reason to finally sort that into the trunk
17:29 < rxr> well - you ask the T2 founder - I probably will answer yes :-)
17:29 < jalsot> right I discovered T2 after some days of PITA with astfin, so I think I have many new things to read 1st at t2-project.org
17:29 < jalsot> hehehe :)
17:30 < jalsot> we are new in this embedded area, but are eager to learn :)
17:30 < rxr> we == a company ?
17:30 < jalsot> bfin/cross-compiling/embedded environment
17:30 < jalsot> yes and no :)
17:31 < jalsot> practically just I have to make a research for bfin compiling stuff
17:31 < jalsot> but yes, we are in a company - in a small company
17:32 < rxr> because if you need external professional support you might find http://www.exactcode.de/ useful
17:33 < jalsot> good to know!
17:33 < jalsot> it's good if an open-source project has commercial support
17:34 < rxr> In the meantime I'll try to sort the bfin bits from my work MacBook into the T2 trunk
17:34 < rxr> that's overdue anyway
17:34 < rxr> actually you are the fist to ask for bfin in T2
17:34 < jalsot> right I downloadad trunk, as I see, there is no bfin yet
17:34 < jalsot> so you are going to add the initial bfin support?
17:34 < rxr> so far we only used it in in-house stuff and with the usual work-load those bits often keep lingering before they are cleaned up for the T2/trunk
17:35 < rxr> blackfin support is already in trunk
17:35 < rxr> but it will not produce perfect binaries
17:35 < rxr> http://svn.exactcode.de/t2/trunk/architecture/blackfin/
17:35 < jalsot> oh, yep
17:35 < rxr> but that are just some defines
17:35 < jalsot> I was checking in target/
17:36 < rxr> other marks are in packages, in form of per-package packages or tag marks like "supports blackfin" or "doesn't"
17:36 < rxr> e.g. dietlibc is marked to not support blackfin, while uclibc does and the like
17:36 < jalsot> nice
17:37 < jalsot> how hard is to add a new application into the toolchain?
17:37 < jalsot> which uses autotools, libtool,...
17:38 < rxr> very easy
17:38 < jalsot> I was trying to add CallWeaver into AstFin but all the time the cross-compiler did something wrong :) ...yes, I could make something wrong - not an expert in this field, yet ;)
17:38 < rxr> just fill out some $name.desc file tags and of you go
17:39 < rxr> t2 has a currently re-review and filled book that goes into print soon
17:39 < rxr> http://www.t2-project.org/documentation/
17:39 < rxr> how to package note:
17:39 < jalsot> wow, excellent
17:39 -!- write_erase [n=olivier@81.80.156.36] has quit ["Leaving"]
17:39 < rxr> http://www.t2-project.org/handbook/html/t2.pacakge.html
17:39 < rxr> oh - that section id has a typo :-)
17:39 * rxr fixing
17:42 < rxr> http://www.t2-project.org/handbook/html/t2.package.html
17:43 < jalsot> thx, I'm full of materials now :)
17:44 < rxr> your welcome
17:44 < rxr> I try to sort the lacal blackfin bits into the trunk so we have full blackfin support in the 7.0 release
17:45 < jalsot> so the current bfin support is buggy, right? but good enough for playing with
17:46 < rxr> ouh ouh
17:46 < rxr> would be better if you start playing with it tomorrow :-)
17:47 < rxr> the current trunk state is my first pass, more bare bone than not ...
17:47 < jalsot> ok, I will check the manuals than :)
17:47 < rxr> but fixing that is mostly just pulling in some overlay patches that update gcc and binutils
17:47 < rxr> depending on your knowledge that takes less than an hour
17:48 < rxr> but I guess you are more a starter, so just browsing the docu and checking it out tomorrow would be better
17:48 < jalsot> my "knowledge" is very weak in this area at the moment, so I need to learn :)
17:49 < rxr> heh, heise featuring D: http://www.heise.de/newsticker/meldung/89975
17:50 < jalsot> but as I see the amount of docs, I will have to read a lot before starting practical experience :)
17:50 < rxr> well - the handbook also covers basics, and classic Unix textual installation you can fastworward skip those parts ...
17:51 < jalsot> :)
17:51 < jalsot> to be honest, I tryed to compile ;)
17:51 < jalsot> according to http://www.t2-project.org/documentation/buildintro.html
17:52 < jalsot> ./scripts/Download -cfg system -required gave an error: ./scripts/Download: line 806: /dev/fd/62: No such file or directory
17:52 < rxr> hm - what system is that ?
17:52 < jalsot> ubuntu dapper in chroot
17:52 < jalsot> x86_64 host
17:53 < rxr> hm
17:53 < rxr> did you manaully chroot before the build ?=
17:55 < jalsot> yes
17:55 < jalsot> the /proc fs is mounted
17:56 < jalsot> http://pastebin.ca/500379
17:57 < rxr> you need a /dev/fd link to /proc/self or so
17:57 < rxr> self/fd
17:57 < rxr> but that is not due T2, that is due Linux Posix FD setup and co
18:00 < jalsot> ln -s /proc/self/fd /dev/fd done.
18:00 < jalsot> it is downloading now :)
18:00 < jalsot> it seems, debootstrap doesn't make this link by itself...
18:06 < jalsot> as I see, you have asterisk package as well, amazing :)
18:06 < jalsot> do you know wether it compiles for bfin?
18:07 < rxr> we reach 3000 packages, soon
18:07 < rxr> including all the fancy stuff like gnome, kde, gpe, eligthenment 16, 17 OpenOffice
18:07 < jalsot> is it possible to add platform dependant patches?
18:07 < rxr> but not all of this cross builds
18:08 < rxr> yes adding patches is very easy
18:08 < rxr> also storing your build-target config permanently
18:08 < rxr> .oO(http://www.tux500.com/)
18:08 < rxr> permanent target config: http://www.t2-project.org/handbook/html/t2.target.html
18:09 < jalsot> thx
18:09 < jalsot> I don't know how could I live without T2 - and with buildroot :)
18:12 < rxr> sepp: despite CIA lagging right now the gcc-4.2 memory hog patch went into trunk some hours ago
18:12 < jalsot> oops, build stopped - I'll wait for new commits than :)
18:13 < jalsot> for bfin, will you use linux-2.6.22-rc2? as it has bfin support now
18:13 < jalsot> or uclinux?
18:13 < jalsot> http://pastebin.ca/500412
18:13 < rxr> I have the former add-on patches in use here
18:14 < rxr> I guess the .22-rc2 suppoort will still have gaps, so some additional feature and driver patches would be needed anyway
18:14 < rxr> but in t2 you can change this all easily as well
18:14 < rxr> e.g. even in your target
18:15 < jalsot> sounds cool
18:21 < jalsot> how many developers are working on T2 usually?
18:22 < rxr> over 20 have write access we have a pretty, fresh worldmap also:
18:22 < rxr> http://www.t2-project.org/startpage/
18:22 < rxr> formerly we had a frappr map with even more pins, but they require flash now
18:23 < rxr> our map uses an own DB, and uses google maps, not all pins we had in frappr flash map are theere yet
18:23 < rxr> but you can get a feeling :-)
18:23 < rxr> also: http://www.t2-project.org/developer/people.html
18:24 < jalsot> oh, nobody from Hungary :)
18:24 < rxr> add yourself, be the first :_)
18:24 < jalsot> ok, I will - tomorrow ;)
18:25 < jalsot> do you add things from blackfin.uclinux.org like SPI kernel driver and libdsp as well?
18:25 < rxr> well - I'll add the last good uclibc kerne patchset
18:25 < rxr> I do not yet have libdsp here
18:25 < CIA-9> rene * r24171 /trunk/package/base/mdadm/ (mdadm.conf mdadm.desc): * updated mdadm (2.6.1 -> 2.6.2)
18:26 < rxr> but that can usually be added easily
18:26 < rxr> which blackfin cpu will you use? custom board ?
18:26 * jalsot is happy to found T2
18:26 < jalsot> custom board in future, currebtly BF537-STAMP
18:27 < CIA-9> rene * r24172 /trunk/package/emulators/pearpc/ (. pearpc.cache pearpc.desc): * added pearpc (0.4) - A PowerPC architecture emulator

15:56 < sepp> hi babygor, write_erase :)
15:57 < babygor> this question should be simple, how do I force a particular gcc version
15:57 < babygor> to be used?
15:57 < babygor> 4.2 is too-bleeding-edge for me :-)
15:58 < write_erase> hi sepp babygor
15:59 < rxr> write_erase: as I noted I only have the STK1000 here
16:00 < rxr> our prototypes always run completey from the SD
16:00 < rxr> so there is no way to damaage the board and the progress can be versioned as SD snapshots or just moving the SD cards around
16:00 < rxr> babygor: use the 6.0 version
16:00 < rxr> T2-6.0 is about gcc-4.2.x and glibc-2.5
16:01 < write_erase> rxr, fine ... Should be the same for my board
16:01 < rxr> while trunk will soon be branched as gcc-4.2 and glibc-2.6
16:03 < write_erase> rxr, Where are the informations for preparing the SD card, and force boot on it ?
16:03 < write_erase> Is that on avrfreak's wiki ?

17:22 < jalsot> hi
17:22 < jalsot> does anybody know what are the main differences between T2 and buildroot [maybe others like OpenEmbedded]?
17:24 < rxr> the main difference is that the T2 code base was the first in the game, created in 1998
17:25 < rxr> and the most portable, generic one and most easy to use
17:25 < rxr> in particular I find OpenEmbedded a PITA to use
17:25 < rxr> http://www.t2-project.org/faq/
17:25 < jalsot> I have some experience with buildroot - on x86, but now I need Blackfin support
17:25 < jalsot> and as I saw, T2 has it :)
17:25 < rxr> .oO
17:26 < jalsot> thx, will look for the FAQ :)
17:26 < rxr> I guess I should hurry commit all the pending local blackfin bits ...
17:26 < jalsot> oh, you are the bfin guy? :)
17:26 < rxr> yeah
17:26 < jalsot> which toolchain do you use in T2?
17:26 < rxr> gcc-4.x + patches
17:27 < rxr> the vanilly gcc has bfin but misses some "state of the art" bits to support the new shared object format commonly used
17:27 < rxr> so current uclibc versions only build with a patched gcc
17:28 < jalsot> wow
17:28 < rxr> in how many hours do you need T2 bfin support? I have quite some pending local changes that need to be added for final support
17:28 < jalsot> so T2 may be a good choice for me?
17:29 < rxr> someone except http://ExactCode.de needing bfin kinda is a reason to finally sort that into the trunk
17:29 < rxr> well - you ask the T2 founder - I probably will answer yes :-)
17:29 < jalsot> right I discovered T2 after some days of PITA with astfin, so I think I have many new things to read 1st at t2-project.org
17:29 < jalsot> hehehe :)
17:30 < jalsot> we are new in this embedded area, but are eager to learn :)
17:30 < rxr> we == a company ?
17:30 < jalsot> bfin/cross-compiling/embedded environment
17:30 < jalsot> yes and no :)
17:31 < jalsot> practically just I have to make a research for bfin compiling stuff
17:31 < jalsot> but yes, we are in a company - in a small company
17:32 < rxr> because if you need external professional support you might find http://www.exactcode.de/ useful
17:33 < jalsot> good to know!
17:33 < jalsot> it's good if an open-source project has commercial support
17:34 < rxr> In the meantime I'll try to sort the bfin bits from my work MacBook into the T2 trunk
17:34 < rxr> that's overdue anyway
17:34 < rxr> actually you are the fist to ask for bfin in T2
17:34 < jalsot> right I downloadad trunk, as I see, there is no bfin yet
17:34 < jalsot> so you are going to add the initial bfin support?
17:34 < rxr> so far we only used it in in-house stuff and with the usual work-load those bits often keep lingering before they are cleaned up for the T2/trunk
17:35 < rxr> blackfin support is already in trunk
17:35 < rxr> but it will not produce perfect binaries
17:35 < rxr> http://svn.exactcode.de/t2/trunk/architecture/blackfin/
17:35 < jalsot> oh, yep
17:35 < rxr> but that are just some defines
17:35 < jalsot> I was checking in target/
17:36 < rxr> other marks are in packages, in form of per-package packages or tag marks like "supports blackfin" or "doesn't"
17:36 < rxr> e.g. dietlibc is marked to not support blackfin, while uclibc does and the like
17:36 < jalsot> nice
17:37 < jalsot> how hard is to add a new application into the toolchain?
17:37 < jalsot> which uses autotools, libtool,...
17:38 < rxr> very easy
17:38 < jalsot> I was trying to add CallWeaver into AstFin but all the time the cross-compiler did something wrong :) ...yes, I could make something wrong - not an expert in this field, yet ;)
17:38 < rxr> just fill out some $name.desc file tags and of you go
17:39 < rxr> t2 has a currently re-review and filled book that goes into print soon
17:39 < rxr> http://www.t2-project.org/documentation/

17:43 < jalsot> thx, I'm full of materials now :)
17:44 < rxr> your welcome
17:44 < rxr> I try to sort the lacal blackfin bits into the trunk so we have full blackfin support in the 7.0 release
17:45 < jalsot> so the current bfin support is buggy, right? but good enough for playing with
17:46 < rxr> ouh ouh
17:46 < rxr> would be better if you start playing with it tomorrow :-)
17:47 < rxr> the current trunk state is my first pass, more bare bone than not ...
17:47 < jalsot> ok, I will check the manuals than :)
17:47 < rxr> but fixing that is mostly just pulling in some overlay patches that update gcc and binutils
17:47 < rxr> depending on your knowledge that takes less than an hour
17:48 < rxr> but I guess you are more a starter, so just browsing the docu and checking it out tomorrow would be better
17:48 < jalsot> my "knowledge" is very weak in this area at the moment, so I need to learn :)
17:49 < rxr> heh, heise featuring D: http://www.heise.de/newsticker/meldung/89975
17:50 < jalsot> but as I see the amount of docs, I will have to read a lot before starting practical experience :)
17:50 < rxr> well - the handbook also covers basics, and classic Unix textual installation you can fastworward skip those parts ...
17:51 < jalsot> :)
17:51 < jalsot> to be honest, I tryed to compile ;)
17:51 < jalsot> according to http://www.t2-project.org/documentation/buildintro.html
17:52 < jalsot> ./scripts/Download -cfg system -required gave an error: ./scripts/Download: line 806: /dev/fd/62: No such file or directory

17:53 < rxr> hm
17:53 < rxr> did you manaully chroot before the build ?=

17:55 < jalsot> the /proc fs is mounted
17:56 < jalsot> http://pastebin.ca/500379
17:57 < rxr> you need a /dev/fd link to /proc/self or so

18:00 < jalsot> it seems, debootstrap doesn't make this link by itself...
18:06 < jalsot> as I see, you have asterisk package as well, amazing :)
18:06 < jalsot> do you know wether it compiles for bfin?
18:07 < rxr> we reach 3000 packages, soon
18:07 < rxr> including all the fancy stuff like gnome, kde, gpe, eligthenment 16, 17 OpenOffice
18:07 < jalsot> is it possible to add platform dependant patches?
18:07 < rxr> but not all of this cross builds
18:08 < rxr> yes adding patches is very easy
18:08 < rxr> also storing your build-target config permanently
18:08 < rxr> .oO(http://www.tux500.com/)
18:08 < rxr> permanent target config: http://www.t2-project.org/handbook/html/t2.target.html
18:09 < jalsot> thx
18:09 < jalsot> I don't know how could I live without T2 - and with buildroot :)
18:12 < rxr> sepp: despite CIA lagging right now the gcc-4.2 memory hog patch went into trunk some hours ago
18:12 < jalsot> oops, build stopped - I'll wait for new commits than :)
18:13 < jalsot> for bfin, will you use linux-2.6.22-rc2? as it has bfin support now
18:13 < jalsot> or uclinux?
18:13 < jalsot>
18:13 < rxr> I have the former add-on patches in use here
18:14 < rxr> I guess the .22-rc2 suppoort will still have gaps, so some additional feature and driver patches would be needed anyway
18:14 < rxr> but in t2 you can change this all easily as well
18:14 < rxr> e.g. even in your target
18:15 < jalsot> sounds cool
18:21 < jalsot> how many developers are working on T2 usually?
18:22 < rxr> over 20 have write access we have a pretty, fresh worldmap also:
18:22 < rxr> http://www.t2-project.org/startpage/
18:22 < rxr> formerly we had a frappr map with even more pins, but they require flash now
18:23 < rxr> our map uses an own DB, and uses google maps, not all pins we had in frappr flash map are theere yet
18:23 < rxr> but you can get a feeling :-)
18:23 < rxr> also: http://www.t2-project.org/developer/people.html
18:24 < jalsot> oh, nobody from Hungary :)
18:24 < rxr> add yourself, be the first :_)
18:24 < jalsot> ok, I will - tomorrow ;)
18:25 < jalsot> do you add things from blackfin.uclinux.org like SPI kernel driver and libdsp as well?
18:25 < rxr> well - I'll add the last good uclibc kerne patchset
18:25 < rxr> I do not yet have libdsp here
18:25 < CIA-9> rene * r24171 /trunk/package/base/mdadm/ (mdadm.conf mdadm.desc): * updated mdadm (2.6.1 -> 2.6.2)
18:26 < rxr> but that can usually be added easily
18:26 < rxr> which blackfin cpu will you use? custom board ?
18:26 * jalsot is happy to found T2
18:26 < jalsot> custom board in future, currebtly BF537-STAMP
18:27 < CIA-9> rene * r24172 /trunk/package/emulators/pearpc/ (. pearpc.cache pearpc.desc): * added pearpc (0.4) - A PowerPC architecture emulator
18:58 < jalsot> rxr: for what kind of project did you use blackfin?

19:09 -!- Enqlave is now known as Stelz
20:00 < sepp> :)
20:01 < sepp> is that gcc 4.2.0 hotfix some bigger patch to overall reduce gcc's gigantic mem footprint
20:01 < sepp> maybe i could enable 2 jobs again without turning my x2 into a c64
20:01 < sepp> :p
20:46 < babygor> rxr, have a minute?
21:21 < Ragnarin> hmm just noticed .... some dirs get created with mode 700, like /opt/kde3/lib64/kde3
