11:03 < mtr> rxr: thanks, things are still developing :) but not as fast and well as expected ...
11:06 < mtr> rxr: and on your side? btw, I noticed your articles in the LM, about cross-compiling, c-libs et.al.
11:07 < mtr> unfortunately spare time for T2 is getting less every month :(
11:12 < DeeKey> Hello
11:13 < DeeKey> I am writing an article about T2 in the light of compilation and cross compilation of RTAI hard real time linux patch...
11:14 < DeeKey> For the conference held in Tallinn.
11:14 < rxr> DeeKey: nice :-)!
11:14 < rxr> mtr: yeah - sort of same here
11:14 < rxr> mtr: though I try to do the morning updates ... :-)
11:15 < rxr> mtr: and I'll probably have to rearrange some cross build staging for gcc-4.3 on trunk sometime soon
11:17 < DeeKey> I also hope that my article and my two rtai targets (one for cross-compilation and the other for chroot compilation) would be of help to the RTAI community.
11:17 < DeeKey> There are tons of mails in RTAI user group starting with "HOW to Compile"
11:17 < DeeKey> almost every day...
11:22 -!- valentin [n=ziegler@luxus.informatik.hu-berlin.de] has joined #t2
11:41 < DeeKey> rxr: just to clarify. It is not possible to cross compile in stage 5? Mean to compile for other architecture?
11:45 < rxr> the stages are exactly for that, defining in which stage it should be
11:46 < rxr> stage 5 is native
11:46 < rxr> stage 1 is cross
11:46 < rxr> if the Cross build option is enabled in the Config all but stage 0-1 is disabled, and all packages marked CROSS in the Flags tag in the .desc are enabled for stage 1 as well
11:47 < rxr> http://www.t2-project.org/handbook/html/t2.build-auto.html#t2.build-stages
11:57 < DeeKey> So It mean, that if I want to create distributive that can both cross compile and natively compile, I need to create two targets?
11:58 < DeeKey> That is the way I am heading now.
12:00 < DeeKey> I have created the second rtai target to natively compile RTAI for x86. That will be the most needed target i suppose. The original rtai target could be used for cross compilation (rtai supports different arch)
12:07 < rxr> nope
12:07 < rxr> if all packages of your distributions to cross build you could of course always just cross build
12:08 < rxr> however, otherwise the Config Cross option would allow to select whether to Cross or Native build
12:08 < rxr> for Native builds just the basic stuff would be cross build then, and then "sort of all the rest" build in the chroot, natively. ...
12:27 -!- Enqlave [n=stealth@sourcemage/guru/stealth] has joined #t2
13:14 < DeeKey> hmm... But the problem is that for cross build the busybox is sufficient, For native it is not. I had to include all the GNU common stuff
13:47 < rxr> hm - indeed
13:47 < rxr> actually we either try to do pure cross builds in our company anyway, for various reasons
13:47 < rxr> and only do native builds if we have to due to packages that do not yet cross build
14:06 < DeeKey> seems that rta-xml wont cross compile...
14:07 < DeeKey> rxr: forget to ask you. What is the conclusion about patch for Python?
14:14 < CIA-4> rene * r28608 /trunk/package/audio/mpg123/mpg123.desc: * updated mpg123 (1.4.0 -> 1.4.1)
14:14 < CIA-4> rene * r28610 /trunk/package/gnustep/gorm/gorm.desc: * updated gorm (1.2.2 -> 1.2.4)
14:14 < CIA-4> rene * r28609 /trunk/package/develop/cln/cln.desc: * updated cln (1.1.13 -> 1.2.2)
14:15 < rxr> DeeKey: rediff and merge :-(
14:15 < rxr> DeeKey: I know that is ugly work ...
14:16 < rxr> DeeKey: regarding rtai-xml, everything can be patched, however, indeed sometimes it can be quite some work and/or ugly
14:16 < rxr> so - gotta lunch - cu soon
14:16 < DeeKey> cu

20:32 < Ragnar|away> rxr: do you get an error when building findutils recently?
20:35 < DeeKey> i dont get any errors.
20:35 < DeeKey> or there was an update?
20:38 < rxr> Ragnar|away: a 1- cross build error, yes :-(
20:44 < rxr> Ragnar|away: do you get the same?
20:47 < Ragnar|away> yea
21:00 < mtr> I posted a findutils patch some days ago to this channel, but have not commited until now
21:00 < mtr> Ragnar|away: you may try http://rafb.net/p/BobJZS48.html
21:02 -!- hoss10123 [n=hoss1012@pix-osh-primary.oracular.com] has joined #t2
21:03 < Ragnar|away> Ill try
21:03 -!- hoss10123 is now known as kb9qwc
21:06 < Ragnar|away> mtr: that works
21:06 < Ragnar|away> wanna commit?
21:08 < mtr> yeah, cross-compiling works, but I did not verify the native stage and the binary yet
21:09 < Ragnar|away> ah ok
21:13 < Ragnar|away> what should it break if it doesn't work?
21:13 * Ragnar|away just emerged it, and the resulting find seems to work
21:16 < mtr> ok, if the native build works, I'll commit as .patch.cross
21:17 < Ragnar|away> ok :)
21:20 < mtr> this gnulib stuff is rather confusing, a local "wchar.h" and and the "#define _GL_WCHAR_H" ...
21:35 < CIA-4> mtr * r28611 /trunk/package/base/findutils/gnulib-wchar.patch.cross: * fixed finutils cross build: added patch for gnulib wchar defines

21:54 < rxr> we also already have base/texinfo/wchar-mbstate-definition.patch
22:20 < |beowulf|> what do I have to do to build a system into a clean chroot?
22:21 < rxr> |beowulf|: just run a Build-Target?
22:22 < |beowulf|> where do I tell it where it should install to? scripts/Config?
22:23 < rxr> a Build-Target always installs into build/$cfg-$UUID.../
22:24 < |beowulf|> so that's where I should mount the partitions I want to install to...
22:24 < rxr> I hope no script gets in your way with such a setup
22:25 < rxr> so in theory, yes
22:25 < |beowulf|> ok, thanks :)
22:25 < rxr> though so far I and probably most people copyed (rsynced etc.) the content after the build somewher,e like on a dedicated partition
22:26 < rxr> sorry for the interim typos, my 3G conection doe snot make fixing typos too easy ...
22:26 < rxr> with like 200ms lag ...
22:26 < |beowulf|> in that case I'll do that
