Debian > Debian GNU > Debian GNU/Hurd

This page attempts to be a reference for all resources related to Debian GNU/Hurd that can be useful for users and developers. Feel free to add more stuff as you see fit.

"In a discussion with the Debian Hurd porters it was decided that the Hurd port stays on FTPMaster until Wheezy is released. Should they have managed to get the port into a state that it is released together with all the others (probably as a technology preview), it is kept in the archive. Should they not manage this the port will be removed from the main archive and move fully to debian-ports.org."¹

What is Debian GNU/Hurd ?

Debian GNU/Hurd is an operating system from Debian, but which uses GNU Hurd, which a set of servers, running on top of the GNU Mach microkernel instead of the kernel named Linux (thus the name Debian GNU/Hurd). Some day, most applications will exist both in Debian GNU/Hurd and in Debian GNU/Linux.

Basic info

• Official port site

• GNU's GNU Hurd

• Installation and testing:

  • http://www.debian.org/ports/hurd/hurd-install

    • Debian "Sid" debian-installer images available http://people.debian.org/~sthibault/hurd-i386/installer/cdimage/.

    • This is the prefered method of install.

  • Cross Hurd

  • Pre-build image files (*.img.*) at http://people.debian.org/~sthibault/hurd-i386/

• ?Debian_GNU/Hurd_FAQ

• TheHurd page. (Merge?)

• User/developer discussion mailing list

• Last bits from the project

• IRC channel: http://www.gnu.org/software/hurd/irc.html

  • #hurd on irc.freenode.net

  • #debian-hurd on irc.debian.org

Goals for releasing in wheezy

  • DSA
• proper dhcp support in installed system
  • use ifup/ifdown instead of translators entry?
• debian-ports packages need to be integrated in the main archive.
  • binutils

    • 629866

    • Not critical, can live without
  • cardmgr-gnumach
    • wifi, can live without

    • we should probably just integrate it in the hurd package
    • See the concerns on the mailing list archive (bug-hurd, "XKB's keymaps for the Hurd console")
  • gcc-4.4 gcc-4.6

    • 629866

  • guile-1.8

    • linked with -lpthread, to avoid dlopen(lpthread) bug, 646544

    • 630415 shows that guile-2.0 will have pthread enabled anyway.

• Integrate DDE to get nowadays' network support.
• Get Xorg + gnome/kde/xfce (xfce should work, kde is missing working dbus (due to local socket auth and bugs in select() cornercases)) + some webbrowser working (iceweasel 9 works, though not https).

Make sure to use the same path in the host and in the target for the compilation.

For the triplet, use i386-unknown-gnu. Better cross-build from an i386 host.

Don't use perl boot: the package is already "booted".

After having run make in the host and transferred the files to the target, fixes are needed in files libraries/unix/dist-install/build/System/Posix/*.hs, basically all lines postfixed by {-# LINE 334 "librari...}

Notably: the offsets in ./libraries/unix/dist-install/build/System/Posix/Files.hs, use the following instead, and fix allocation from 96 to 128.
