Possibly, but the last time I tried the Debian Hurd install was a pain.  And I should be able to cross-compile from any Unix like OS... it is the whole point of all the complexity in the toolchain and I want to do so!  tongue

Re: The Arch Hurd Project

I was trying to be cleaver and prevent redownloading sources I already had so that was not so well tested...   tongue

Change lines 49 and 53 to:

  wget http://ftp.gnu.org/gnu/gcc/gcc-$GCC_VER/<...>

Not literally.... but you should get the idea.

It doesn't support x86_64 ? Which CHOST target should I choose ?

Re: The Arch Hurd Project

No idea if you can even get a 64-bit hurd.   I have never seen one.  Try and see but I am not hopeful...  You can build for 32-bit hurd.

Re: The Arch Hurd Project

gcc-4.2/4.3 do not build for hurd:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28102

gcc-4.4 fails linking in stage2 (it can not find libc for some weird reason...  it definitely is right there).

So updating gcc to a newer version is not so fun.

Edit: I can get glibc building against binutils-2.20 with a sed to the configure but then I end up with linking errors.  I guess we would need a newer glibc/gcc version for the new binutils...

So, I am going to get this building for i686-pc-gnu and move on.

Re: The Arch Hurd Project

And that fails.  Building for i686-pc-gnu results in this failure in glibc:

/home/allan/hurd/build/glibc/rt/librt_pic.a(clock_settime.os): In function `clock_settime':
clock_settime.c:(.text+0x3c): undefined reference to `CPUCLOCK_WHICH'
clock_settime.c:(.text+0x4c): undefined reference to `CPUCLOCK_WHICH'
collect2: ld returned 1 exit status
make[2]: *** [/home/allan/hurd/build/glibc/rt/librt.so] Error 1

I can not find a fix for that.  So this cross-compile environment is about as good as it will get.

Re: The Arch Hurd Project

Made a couple of small updates to the script.  I noticed some errors in how I handled downloading the sources only once.


Edit: looking at the next step, we can reuse the gnumach-headers, hurd-headers, libpthread and glibc if we install them in a different directory.  CLFS uses "cross-tools" for native binaries and "tools" for cross binaries.  We should try something like that too.  The current script produces a cross compiler that is too naive to use for building a final system...

But after the packages already built, we only really need to build gnumach, hurd, coreutils and bash to boot our system tongue   Of course, we need a lot more for that system to be useful for packaging...

Re: The Arch Hurd Project

Another day...  more progress:
http://allanmcrae.com/scripts/crosshurd.tar.gz

Changes:
- directory layout
    $ROOT/cross - cross compiler (host system) binaries
    $ROOT/hurd - GNU system install
- scripts
    separated into individual scripts to build individual parts
- started building more of the GNU system (gnumach kernel success, hurd fail...)

The hurd build fails due to needing a newer glibc.  But given the patchset is only for glibc-2.7....    I could revert the relevant commit but I have sent a message to the hurd mailing list to find out if there is a better way.

Re: The Arch Hurd Project

BIG UPDATE!

Changes 20100111:

updates:
  glibc 2.7 -> 2.10.1
  gcc 4.1.2 -> 4.4.2

new cross compiles:
  hurd (from git)
  coreutils-8.3 added
  bash-4.1 added
the last two before those packages make Arch!  (I am waiting on coreutils-8.4...).


If people want to help, what they could do is:
- try update to binutils-2.20 (uncomment the sed in glibc-pass1) - I anticipate no issues.
- try rebuilding for i686-pc-gnu adding this patch in glibc-pass1: http://patch-tracker.debian.org/patch/s … ttime.diff
- create a script to cross compile grub (0.97? - may be easier to deal with initially trying to get a booting system).
- and if you are really, really, really brave...  try glibc-2.11.1 (update patches, look to Debian Sid eglibc package for new ones)

If you are trying to update binutils or the target, it is easier to source the files in the script directory one at a time to catch errors rather that using the makeall script.


I will now put all tarballs in http://allanmcrae.com/hurd/ with a date so just download the latest.

Re: The Arch Hurd Project

Grub 0.97 build script:

#!/bin/bash

cd $SOURCE_DIR
if [ ! -f grub-$GRUB_VER.tar.gz ]; then
  wget ftp://alpha.gnu.org/gnu/grub/grub-$GRUB_VER.tar.gz
fi

cd $BUILD_DIR
rm -rf grub-$GRUB_VER
tar -xf $SOURCE_DIR/grub-$GRUB_VER.tar.gz

rm -rf grub-build
mkdir -p grub-build
cd grub-build

../grub-$GRUB_VER/autogen.sh
../grub-$GRUB_VER/configure \
  --host=$TARGET \
  --prefix=/usr
make DESTDIR=$HURD_DIR install

cd $ROOT

Also, add a line to ./scripts/prepare:

GRUB_VER=0.97

edit: Works! Anybody feel like working on GRUB2? tongue

That tells me the failure is really in gcc-pass2.   Comment everything from the make statements down in the gcc-pass2 script and then run those  commented commands manually to see the real breakage.

Re: The Arch Hurd Project

Update: 20100112

Changes:
- Build for i686-pc-gnu.  Thanks to Samuel Thibault on the bug-hurd mailing list for providing part of a patch to allow this.
- Added grub(-legacy).

I think we actually have enough packages for a bootable system now...  but there are still a lot of config files missing (and maybe a text editor would be nice!). You can get some idea of what is needed from here (in French) .  Also the Debian install page provides info on setting up the partition.

I do not have a spare partition at the moment so I will be using a qemu image. It seem it will be essentially make the image, make filesystem on image, mount image to $ROOT/hurd, build...  The image has to be in .img format for the mounting but I think it can be converted to the smaller .qcow2 format after the install.  I guess we can provide an image as our first step into a real Arch Hurd!
