At the moment I'm trying to run some of the code from the extracted firmware image inside my emulator image. However, only some files work while others just crash. I'm pretty certain that this comes from the memory mapping. Do you guys have any experience with that ? Is it possible to re-define memory-mappings ? |

| 21:20.37 | landley | Not Especially Morning. |
| 21:27.32 | slashbeast | landley: yo, did you tried to build lvm2 under Aboriginal? |
| 21:27.49 | landley | slashbeast: not yet. I'd be interested to see what happens. |
| 21:28.13 | slashbeast | landley: I needed to replace busybox with mine supporting -exec to find, then: http://paste.pocoo.org/show/HwhLdY358Zu394smvtUN/ |
| 21:28.36 | slashbeast | and of course the autoconf/install-sh is there. |
| 21:31.13 | slashbeast | landley: any idea whats going on? I wanted run autoconf on it, but it does need perl which I am not able to compile under aboriginal too. |
| 21:31.35 | landley | slashbeast: I need to replace busybox with toybox. :) |
| 21:31.59 | landley | Although you can try the Linux From Scratch root filesystems, which have all those gnu packages installed, as an easier starting point for some stuff... |
| 21:32.34 | landley | slashbeast: look at autoconf/install-sh |
| 21:32.54 | landley | It might be a shell script wanting a #!/not/there file. |
| 21:33.11 | landley | I compiled perl. |
| 21:33.17 | landley | It's part of the linux from scratch build. |
| 21:33.41 | slashbeast | it does start with #! |
| 21:33.55 | slashbeast | and I need to bootstrap lvm2 for the initramfs usage. |
| 21:34.10 | landley | http://landley.net/http://landley.net/hg/control-images/file/tip/images/lfs-bootstrap/mnt/build/perl.sh |
| 21:34.36 | landley | You have to hit the perl build in the head with a brick, but then it builds. |
| 21:34.44 | landley | Might need some of the earlier things as prerequisites, the sequence is in... |
| 21:34.58 | landley | http://landley.net/hg/control-images/file/73b8cbdef3b5/images/lfs-bootstrap/mnt/package-list |
| 21:35.31 | landley | I have no idea why "landley.net" is in that first link twice, my bad. |
| 21:35.48 | landley | slashbeast: initramfs usage...? |
| 21:37.38 | slashbeast | landley: I have rootfs on lvm. |
| 21:37.44 | slashbeast | thus I need to setup it on initramfs. |
| 21:38.04 | slashbeast | Checking for GNU C Library... |
| 21:38.04 | slashbeast | try.c:12:41: error: gnu/libc-version.h: No such file or directory |
| 21:38.11 | slashbeast | then it failing to check with ar the /lib/libc |
| 21:43.49 | landley | Ah, I was confusing lvm with llvm. |
| 21:43.57 | landley | Logical Volume Manager, right. |
| 21:44.30 | landley | People hardwire in horrible glibc dependencies, and then never test any sort of "else" case. |
| 21:44.37 | landley | Why the bother using autoconf, I couldn't tell ya... |
| 21:44.51 | landley | "Our configuration system supports exactly one case". So... what's it for, then? |
| 21:44.58 | slashbeast | I thought I could build autoconf and run it, thatshould fix the configure via configure.ac |
| 21:45.07 | landley | shrugs. Maybe? |
| 21:45.20 | landley | I think the linux from scratch bootstrap stuff natively builds autoconf... |
| 21:45.40 | landley | http://landley.net/hg/control-images/file/tip/images/lfs-bootstrap/mnt/build |
| 21:45.45 | slashbeast | so I need to build a lfs via aboriginal to build lvm and few things |
| 21:45.53 | landley | http://landley.net/aboriginal/control-images |
| 21:46.03 | landley | I need to cut a control images release this weekend to go with 1.1.1. |
| 21:46.12 | slashbeast | all I wanted was a uclibc-enabled chroot, argh. |
| 21:46.13 | landley | I think the old ones are still LFS 6.7, and I upgraded to 6.8. (And 7.0 is out...) |
| 21:46.20 | slashbeast | (╯°□°）╯︵ ┻━┻ |
| 21:46.32 | landley | slashbeast: possibly you can chop out the crap llvm shoudn't be doing? |
| 21:46.54 | slashbeast | I am unable to find what exacly is wrong with the lvm configure |
| 21:46.54 | landley | That's generally the best approach when confronted with GNU/FSF/Dammit contamination: chop it out and cauterize the stump. |
| 21:47.00 | slashbeast | well. configure is okey, the make failing |
| 21:47.18 | landley | The make is complaining that install-sh is calling a #!/thingy that isn't there? |
| 21:47.25 | landley | what specific #! line does it start with? |
| 21:47.27 | slashbeast | #!/bin/sh |
| 21:47.35 | landley | I'm pretty sure there's a /bin/sh... |
| 21:47.39 | landley | I symlinked it to bash, I think? |
| 21:47.49 | landley | (It's bash 2, but should still work...) |
| 21:47.51 | slashbeast | yep it is, tried to link to to anything else like ash, still the same |
| 21:48.19 | landley | Throw a couple of "echo blah >&2" statements into the thing and see if it's complatining at the start or later in the file? |
| 21:48.55 | slashbeast | it does run install-sh with arguments, a really weird one |
| 21:49.02 | slashbeast | see the paste I linked above |
| 21:50.46 | landley | What happens if you run autoconf/install-sh with no arguments? |
| 21:51.16 | slashbeast | # autoconf/install-sh |
| 21:51.17 | slashbeast | autoconf/install-sh: no input file specified. |
| 21:51.33 | slashbeast | added -r to Configure in perl, its building. |
| 21:51.58 | landley | Try "autoconf/install-sh -c -d format1/" |
| 21:52.12 | *** join/#edev vpopov (~happylife@dyn-58-222.fttbee.kis.ru) |
| 21:52.36 | slashbeast | no output, return status 0 |

| 21:53.22 | landley | Try running it from the "lib" subdirectory? |
| 21:53.54 | slashbeast | perl installed. :d |
| 21:53.55 | landley | If there isn't a lib/autoconf/install-sh then there's probably a $PREFIX variable of somekind that make is setting wrong. |
| 21:54.12 | landley | slashbeast: there is no way a smiley is warranted about installing perl. |
| 21:54.18 | landley | That's a "destroy the village to save it" sort of thing... |
| 21:54.43 | slashbeast | landley: :o |
| 21:54.47 | slashbeast | ln -s ../autoconf did the trick |
| 21:54.49 | slashbeast | it does compiling |
| 21:55.00 | landley | slashbeast: look in the makefile to see where it's getting autoconf/install-sh from and what variable it's prepending to that pathwise, and why that variable isn't being set right. |
| 21:55.12 | landley | Or you can do the symlink, yes. :) |
| 21:55.19 | landley | You'll probably have to do it in more than one directory, though... |
| 21:55.21 | slashbeast | qI need to link autoconf dir in every subdir |
| 21:55.46 | landley | Or you could figure out what make variable is being set wrong so not calling it with the right path... |
| 21:56.34 | landley | (I have debugged _so_ much of this stuff. People write really really brittle build systems and then go "but it compiled on Red Hat Enterprise with magic versions of 630 packages installed"...) |
| 22:00.23 | MonMotha | landley: sounds like most code from various embedded chip vendors |
| 22:00.49 | MonMotha | "Well, it builds with this 10 year old version of IAR that I had laying around, with certain weird command line options turned on that I didn't document and lost 2 years ago, and I think it may have even worked." |
| 22:00.58 | landley | MonMotha: most code _everywhere_, really. |
| 22:01.22 | MonMotha | landley: sad... Maybe I'm just spoiled by the quality of major open source project code |
| 22:01.30 | landley | What open source is really good at doing, better than any other development process, is taking something that works but isn't particularly reproducible and cleaning it up. |
| 22:01.32 | MonMotha | like hacking on the Linux kernel is a dream, usually |
| 22:02.35 | landley | It takes rarified expertise to do new stuff with hardware and protocols most people have never heard of, but taking something that works and cleaning it up? Anybody can do that, they just have to put in the time and effort. |
| 22:02.35 | slashbeast | ld: unrecognized option '--no-export-dynamic' |
| 22:02.36 | MonMotha | I think I get in trouble with some of my clients initially for spending the extra 10% time-wise to make my code somewhat clean, but then if the project needs any maintenance, they easily make it back (and I'm not sure are aware of that fact) |
| 22:02.44 | slashbeast | landley: any idea whats going on here? |
| 22:02.56 | landley | Oh, somebody asked me about that... |
| 22:03.01 | slashbeast | too old gnu ld? |
| 22:03.03 | landley | I have to hack it into binutils 2.17. |
| 22:03.11 | landley | It's a musl thing, if I recall... |
| 22:03.27 | slashbeast | lvm with --enable-static does it |
| 22:03.32 | slashbeast | try to call it. |
| 22:03.34 | landley | I have a todo item for it somewhere. |
| 22:03.50 | landley | Why would --static _also_ need a --no-export-dynamic flag? |
| 22:03.53 | landley | You'd think the first would cover it... |
| 22:05.08 | landley | Looking at the man page, it restores default behavior. Wheee... |
| 22:05.30 | landley | I can hack this into the linker, email me and I'll try to get to it this weekend after the toybox release. |
