mjg59fabbione: I just got an oops in inotify01:12
mjg59I tried unmounting an ntfs partition01:12
mjg59(this is 2.6.12 as of Wednesday)01:13
jbaileyThere's no __NR_sigaction on x86_64.  Does the 32-bit emulation on amd64 promise to do all to 32bit syscalls?01:14
Mithrandirjbailey: I would think so, yes.01:15
Mithrandirit's supposed to be a 100% emulation01:16
jbaileyOh good. =)01:16
jbaileySo now all we need is glibc headers that DTRT.01:16
jbaileyMithrandir: Is there any hope of us doing multiarch at least a little bit for Breezy? =)01:16

Mithrandirjbailey: you mean "a little bit more"? :)  I'm hoping to get some time allocated for actually coding up a bit once I'm done with my thesis01:17
Mithrandirdoing binutils + gcc support should either already be there or easily fixed.01:17
jbaileyMithrandir: I'd love to see at a base just have gcc look in the multiarch directories for -m64 and -m32 as well as the standard directories.01:18
jbaileyWe can then take the current biarch packages and have it put things in the right places.01:18
jbaileyIncluding all the header files and such.01:18
Mithrandirjbailey: get doko to apply a set of fixes from http://arch.err.no/index.cgi/tfheen@idi.ntnu.no--2005/gcc-debian--multiarch--3.4 and you're set.01:18
jbaileyNothing from dpkg would need to be touched, basically just gcc, glibc, lkh, ncurses and zlib.01:18
jbaileyAnd it's all stuff we could do in our sleep today.01:18
Mithrandirthat's easy enough to do, sure.01:19
jbaileyI suspect that doko's current libjava on 32 bit arch problem will give him incentive to say yes. =)01:19
Mithrandirheh :)01:19
Mithrandirthis won't give you coinstallability until dpkg is fixed, though01:20
jbaileyHe's running into the fact that i386 and amd64 aren't like ppc, sparc and s390 in glibc.01:20
Mithrandiroh, fun01:20
jbaileyNoone in glibc land ever intended it to be a biarch arch AFAICT.01:20
jbaileySo the headers don't seem to easily cope with each system.01:20
Mithrandirwhich is the reason for the crack in amd64-libs-dev to divert headers and such?01:21
jbaileyPartly, but mostly amd64-libs crack is due to the fact that Sarge wasn't shipping with amd64.01:21
Mithrandirthat too01:21
jbaileySo no compiler support, so no way to make proper biarch packages.01:21
Mithrandirtrue01:22
Mithrandirit's also aiming for a bit more than ia32-libs-dev which is "this is enough to give you a crosscompiler"01:22
jbaileyRight. =)01:33
jbaileySo assuming doko agrees, that patch is all that needs to be applied to 3.4 to make it look in /usr/include/${GNU_ARCH} and /usr/lib/${GNU_ARCH} before the regular search paths?01:34
Mithrandiryou need to fix up binutils too, but yes.01:36
jbaileyRight - for ls/.01:37
jbaileyld.01:37
Mithrandirin the cases of people calling ld directly, for instance.01:37
Mithrandirgcc DTRT and passes the right parameters, but it's not always enough01:37

jbaileyCan the ia64 kernels run i386 binaries if the appropriate libraries are hanging around?11:40
dokojbailey, they should11:41
jbaileydoko: I'm just wondering how many multiarch setups we'll need.  I imagine the trouble you're running over with OOo is going to have to be repeated for ia64 at some point.11:42
dokohmm, who does run OOo on ia64? ;-)11:46
Mithrandirdoko: insane people.  That means, everybody who uses ia64.11:46
jbaileyMithrandir: That's not fair.  I don't use OOo anywhere, much less on my ia64. =)11:47
Mithrandirjbailey: well, you're a glibc hacker so you're insane, hands down. :-)11:48
jbailey;P11:48
Mithrandiractually, I didn't say that everybody with an ia64 used ooo, just that they were insane.11:49
dokoMithrandir: amu reports 100% CPU usage when installing the new bash package on amd64, can you confirm that?11:49
Mithrandirdoko: just installing it?11:49
dokono, using it11:49
Mithrandirgive me a few secs11:49
Mithrandirjust by launching it and running some commands?11:51
Mithrandirif so, can't duplicate.11:51
dokohmm, strange, maybe you could ask amu tomorrow11:52
MithrandirI'll try to remember.11:52
dokothanks11:54
