| fabbione | morning | 06:31 |
| desrt | fabbione; do you still need access to gorecki? | 07:21 |
| fabbione | desrt: nope.. thanks :) | 07:21 |
| desrt | awesome | 07:22 |
| === desrt resumes the crashing :) | ||
| fabbione | desrt: i am confident you did try the new headers.. didn't you? | 07:22 |
| desrt | fabbione; actually, no | 07:23 |
| desrt | fabbione; i've been avoiding too much kernel hacking so that i didn't accidentally crash the box when you needed to use it :) | 07:23 |
| fabbione | oh | 07:23 |
| fabbione | thanks :) | 07:23 |
| fabbione | well crash it and let me know :) | 07:23 |
| desrt | k. lemme check | 07:23 |
| fabbione | i need to go offline soon for approx 20 minutes | 07:24 |
| desrt | MODPOST | 07:24 |
| desrt | modpost: /home/desrt/coconet/coconet.o no symtab? | 07:24 |
| desrt | /bin/sh: line 1: 14814 Aborted scripts/mod/modpost -m -a -i /usr/src/linux-headers-2.6.12-3-powerpc64-smp/Module.symvers /home/desrt/coconet/coconet.o /home/desrt/coconet/large-page.o | 07:25 |
| desrt | very possibly my fault :) | 07:25 |
| fabbione | yes | 07:25 |
| fabbione | i saw that too | 07:25 |
| fabbione | but given that all the rest compiles... | 07:25 |
| fabbione | i sort of assumed it was a specific coconet problem | 07:26 |
| desrt | let me check | 07:26 |
| desrt | no. it's a -headers problem, i think | 07:26 |
| desrt | i'll try and find out more about it while you're offline | 07:27 |
| fabbione | i don't think it is | 07:27 |
| desrt | (compiles just fine against the full kernel source 2.6.12 with ubuntu patches) | 07:27 |
| fabbione | hmmmm | 07:27 |
| fabbione | ok... leave my account around.. | 07:27 |
| fabbione | i will look at it later | 07:27 |
| fabbione | desrt: did you actually upgrade the kernel and headers to the latest version or are you just using the one i hacked locally? | 07:28 |
| desrt | whatever is currently in /usr/src/linux-kernel-headers | 07:29 |
| fabbione | currently as in? | 07:29 |
| fabbione | currently can be that you dist-upgraded the box 2 minutes ago | 07:29 |
| fabbione | or currently is what i left there a few days back :P | 07:29 |
| desrt | i just did dist-upgrade now.. the only difference was a new yaboot | 07:29 |
| fabbione | yeah the yaboot we fixed together | 07:29 |
| desrt | nod. i'm only running ubuntu-base... so not many updates | 07:30 |
| fabbione | ok gimme a bit and i will come back | 07:30 |
| desrt | ok.. i've found the problem.. and it's one of those big sort of problems that won't easily go away | 07:43 |
| fabbione | desrt: re | 07:43 |
| desrt | /usr/src/linux-headers-2.6.12-3-powerpc64-smp/scripts is a symlink to linux-headers-2.6.12-3/scripts | 07:43 |
| desrt | ie: all the various different arch versions share the same scripts/ directory | 07:44 |
| fabbione | that's right... | 07:44 |
| desrt | the modpost script has a compile-time flag for 32bit or 64bit mode | 07:44 |
| desrt | if you run the 32bit version on a 64bit .o file you get the "missing symtab" error | 07:44 |
| desrt | it gets its settings from elfconfig.h | 07:44 |
| desrt | which contains this: #define KERNEL_ELFCLASS ELFCLASS32 | 07:45 |
| desrt | you'll basically need 2 versions of the modpost script... one for 32bit kernels and one for 64bit | 07:45 |
| fabbione | crack | 07:46 |
| fabbione | we need a completely different approach here :/ | 07:47 |
| fabbione | bah | 07:47 |
| fabbione | ok.. i got the problem thanks... | 07:47 |
| desrt | thanks again for all your work on this :) | 07:47 |
| fabbione | this is going to be a real problem | 07:48 |
| desrt | btw: there is a working version of the kernel source in /usr/src/linux-source-2.6.12 that you can use for comparison | 07:48 |
| fabbione | nah i got it thanks | 07:48 |
| desrt | if you compile coconet the top line in the Makefile is LINUX=/path/to/source | 07:48 |
| fabbione | this is going to cost me an extra amount of painful work | 07:48 |
| desrt | anything i can do to help? | 07:49 |
| fabbione | desrt: not really.. this needs to be fixed in the source package... | 07:49 |
| desrt | (just think -- you're solving the problem for biarch amd64 too) :) | 07:49 |
| fabbione | when we build the kernel on the buildd's | 07:49 |
| fabbione | that's the real problem | 07:49 |
| fabbione | desrt: nope.. ppc64 is a "special case" all over the Makefiles | 07:49 |
| desrt | ah | 07:50 |
| fabbione | because it's the only one that's cross compiled | 07:50 |
| daniels | god I hate building the monolith | 07:50 |
| daniels | even with it not building anything in programs/ except for the server and most of lib/ | 07:50 |
| daniels | hate hate hate | 07:50 |
| fabbione | don't worry.. the machine i use to build is fast :) | 07:50 |
| desrt | daniels; Xc? | 07:50 |
| daniels | desrt: yeah | 07:50 |
| desrt | i really like the fd.o broken-out-everything approach with pkgconfig help | 07:51 |
| fabbione | my back is hurting a lot | 07:51 |
| fabbione | crap i must have slept really bad this night | 07:51 |
| desrt | clearly an indication that you require a mid-morning nap :) | 07:52 |
| fabbione | desrt: i am not just tired.. my back is really hurting a lot | 07:52 |
| daniels | desrt: you're telling me | 07:54 |

| mirak | hello | 04:14 |
| mirak | I am trying to cross compile | 04:14 |
| mirak | my two architectures are ppc and i386 | 04:14 |
| mirak | I tried the howto | 04:14 |
| mirak | but it both fail when I try to build gcci386 for ppc and gcc-ppc for i386 | 04:15 |
| jbailey | Which howto? | 04:16 |
| jbailey | If it was anything other than http://kegel.com/crosstool/ you'd probably do better to start for there. | 04:16 |
| mirak | jbailey /usr/share/doc/toolchain/howto | 04:49 |
| mirak | I use this how to | 04:49 |
| mirak | I already followed the http://kegel.com/crosstool/ | 04:50 |
| mirak | some month ago but it failed as well | 04:50 |
| mirak | I use tpkg-make | 04:50 |

| karim | hi | 07:04 |
| karim | how important are the glibc version and kernel version for cross compiling | 07:04 |
| karim | ? | 07:04 |
| karim | jbailey: hey | 07:05 |
| jbailey | The versions shouldn't really matter. Cross compiling on older stuff might be a bit more finicky but not much. | 07:05 |
| jbailey | You generally want to make sure your libraries that you're using for cross compiling are the same or older than the ones you'll be executing with. | 07:05 |
| jbailey | Otherwise you risk symbol mismatches and stuff. | 07:05 |
| karim | here is what I want to do | 07:08 |
| karim | I want to set up a cross compile gcc | 07:08 |
| karim | to use with distcc | 07:08 |
| karim | my goal is to use this ubuntu i386 box to help this poor ppc G3 | 07:08 |
| karim | so I don't think I need all the gdb and stuff to do that | 07:09 |
| karim | jbailey: I don't understand why toolchain tpkg-make script fails | 07:09 |
| karim | it's a pity because it's very handy | 07:09 |
| jbailey | I haven't used that script, so I don't know. | 07:10 |
| jbailey | I have some vague dreams of making it so that building cross compilers from the standard toolchain packages is trivial, but I haven't taken them past the dream stage. | 07:10 |
| karim | well it IS trivial | 07:17 |
| karim | but the compile fail | 07:17 |
| karim | a problem with some files missing it seems | 07:17 |
| karim | signal.h | 07:17 |
| jbailey | IIRC, signal.h means you don't have glibc headers in place. | 07:31 |
| zul|working | someone should start an arm port.. | 07:41 |
| jbailey | Planning on it. | 07:45 |
| === jbailey needs to get around to writing up the buntu spec. | ||
| zul|working | wasnt there a paper at debconf for porting debian to another arch? | 07:57 |
| jbailey | Dunno. I've done it twice, so wouldn't need much of a paper. | 07:57 |
| karim | jbailey: how do I put them in place ? | 08:12 |
| jbailey | karim: It depends where you've configured gcc to look for them. | 09:06 |
| jbailey | I tend to use --with-sysroot | 09:06 |
| karim | hem I am trying to use distcc | 09:09 |
| karim | I can remotely connect and compile | 09:09 |
| karim | but I don't know how to tell distccd to use the ppc gcc cross compiler | 09:09 |
| jbailey | Dunno. I've read about doing that but have never done so. | 09:13 |
| jbailey | I thought about doing that for the Debian hurd-i386 buildd. =) | 09:13 |
| === doko [~doko@a130-233-5-210.debconf5.hut.fi] has joined #ubuntu-toolchain | ||
| jbailey | Have a huge ccache tied in with distcc and cross compilers. | 09:14 |
| jbailey | Make the hurd the fastest compile farm in Debian. =) | 09:14 |
| jbailey | Of course, doko might kill me for thinking that thought out loud. =) | 09:14 |
| doko | ? | 09:14 |
| doko | so you did fix the biarch i386 builds? | 09:15 |
| doko | ;) | 09:15 |
| jbailey | karim: Or he'll play dirty. =) | 09:15 |
| karim | what ? | 09:16 |
| karim | I give up | 09:25 |
| karim | if I compile for ppc on the i386 I can execute the binary on the ppc host | 09:42 |
| karim | so cross compile work | 09:42 |
| karim | but however distcc fail | 09:42 |
| === lamont [~lamont@15.238.5.95] has joined #ubuntu-toolchain | ||
| karim | it produce a little binary | 09:42 |
| karim | that can't be executed | 09:43 |
| doko | lamont, lamont-away: 4.0 did fail on the ia64 and hppa unstable buildds | 10:02 |
| lamont | figures | 10:02 |
| jbailey | Eh? What's different than in breezy? | 10:19 |
| doko | nothing is different. the ia64 buildd looks seriously broken | 10:23 |
