Hello everybody. I found ArchHurd today (I use ArchLinux). I´m a beginner in the programming world, but I´d help in everything I can. Seems great idea make real a GNU System with a Hurd kernel, specially if it´s in Arch way .
Well, I´ll try to boot ArchHurd this night .
(Sorry about my english)

Nice avatar. Gates ist der Fuhrer?

Just an update. The improved cross build method I am working on gets most of the way to booting then fails. It looks like an issue with a missing file (although I am not sure if that is correct or what file...)

I am testing whether my downgrading gcc to a "working" version and the need patches is causing the issue by rebuilding the "old" way and seeing if that boots. I will report back tomorrow.

Does it look like this?

Hurd server bootstrap: ext2fs.static[device:hd0s1] execext2fs.static: ../../hurd
/libdiskfs/boot-start.c:396: diskfs_execboot_fsys_startup: Unexpected error: No 
such file or directory.

Yes and no. that error is a missing /servers/exec file. My error is on line 278, which is something else...

Did you try:

touch /servers/exec

http://www.archhurd.org/installing.php

I guess you did

EDIT: I solved my problem with touching /servers/exec && chmod 1777 hurd/tmp

So... here is my status...

gcc-4.4 does not build a working C++ cross compiler. It gives errors such as:

<path>/lib/gcc/i586-pc-gnu/4.4.0/../../../../i586-pc-gnu/lib/libgcc_s.so: undefined reference to `__multf3'
<path>/lib/gcc/i586-pc-gnu/4.4.0/../../../../i586-pc-gnu/lib/libgcc_s.so: undefined reference to `__fixunstfsi'
<path>/lib/gcc/i586-pc-gnu/4.4.0/../../../../i586-pc-gnu/lib/libgcc_s.so: undefined reference to `__subtf3'

gcc-4.3 does not build a booting hurd. The error message is:\

Hurd server bootstrap: ext2fs.static[device:hd0s1] exec initext2fs.static: boot-start.c:278: diskfs_start_bootstrap: Unexpected error: No such file or directory.

Apart from gcc headers, there is no file difference between the gcc-4.4 and gcc-4.3 builds so that error message is misleading...

I can not find a patch for either. Taking it to the hurd-bug list.

Hey,
First of all many thanks for the great crosshurd script, great way to get started working on this fun project

I switched to gcc-4.2 for that reason and I managed to compile a booting system and even get gcc-4.4 semi-working on hurd (I am missing crtbegin.o, looking into that atm)

Another problem I am having is the login shell. When I try to login I always get rejected with:

login: Authentication Failure: Operation not permitted

I was thinking that it's somehow related to file permissions but after some testing it seems to be something else.
Anybody have any ideas?

EDIT: Solved the login problem, I was missing the /hurd/password translator at /servers/password

What patches do you use to get gcc-4.2 to build?

I only used the gcc-4.2-target-configuration.patch from http://git.savannah.gnu.org/gitweb/?p=h … c898b4df25

I didn't change anything else in your cross-gcc scripts except commenting out the 'make all-target-libgcc install-target-libgcc' line in cross-gcc-pass1

To build gcc-4.4 for hurd I had to set SYSTEM_HEADER_DIR manually when building.

Barrucadu · 2010-02-11 22:24:25

Any progress?

melpo · 2010-02-13 14:00:27

Party time \o/

Using gcc-4.2.4 as cross-compiler I managed to get gcc-4.4.3 working on hurd (only tested with very trivial programs yet)
There are some weird problems when compiling libgcc which seem to result from the Makefile not passing the CC value correctly and creating a bad libgcc. I haven't looked into it any further yet though.

I will upload my changes to the crosscript as soon as I got everything cleaned up and tested.

Allan · 2010-02-13 14:12:08

I was trying to do the CLFS approach to avoid all the issues with the toolchain.

Here is the progress: http://allanmcrae.com/hurd/crosshurd-20100213.tar.gz It will require manual intervention to get the source...

Note that with gcc-4.4 it fails to build a working C++ compiler so fails cross compiling packages needed for the toolchain. gcc-4.3 works, but I can not get the image booting. A quick test with gcc-4.2 did not boot but I have no time to look further due to work commitments.

Optln · 2010-02-14 03:20:34

Great project! I was interested in Hurd for a while but couldn't find a starting point. I'll try it right away.

By the way, http://repo.archhurd.org/crosshurd/ currently doesn't working.

Installling page fixed.

Vamp898 · 2010-02-14 10:04:57

I thought there are no sound drivers on Hurd? So i expect no much fun with flash xD

hatten · 2010-02-14 12:06:28

Uhm, they haven't got a bootable system yet, although they are close. I don't think flash is especially high on the to-do list, or gnash as it gotta be free.

melpo · 2010-02-14 14:40:47

Mh I don't seem to be able to reproduce my working system in a clean environment....

I'm also experiencing some problems booting a gcc-4.2 compiled kernel. Seems that we need gcc-4.4 to compile a booting kernel, 4.2.4 to compile the toolchain.
So any ideas? In my opinion getting the gcc-4.4 c++ compiler working would be a good solution but I haven't found time yet to work on it. I'll try to make some progress on that next weekend

brendan · 2010-02-14 19:27:07

why not dump i686 and go straight to 64bit on this?

jac · 2010-02-14 19:32:00

@brendan: That would require a bunch of coding, as right now HURD is only 32bit.

fair enough, I was thinking that might be the reason.

Allan · 2010-02-14 20:25:47

Yeah... we can not even go i686 and the kernel has issues with that.

sand_man · 2010-02-15 05:32:47

...does hurd even work?

*hides in a corner*

Allan · 2010-02-15 05:47:10

Until I saw the screenshot on this page (http://www.gnu.org/software/hurd/hurd/status.html), I thought the same thing...

Why don't build the C++ compiler with 4.3 and hurd with 4.4?

EDIT:
I get this message when compiling gnumach

/bin/sh: mig: command not found
