Re: (Newbie question) Failed building hurd on Debian GNU Hurd

[James Clarke]

That’s an issue with the current Hurd repo on Savannah. You need this patch 
http://darnassus.sceen.net/gitweb/teythoon/packaging/hurd.git/blob/HEAD:/debian/patches/proc-task-notify-0005-proc-fix-build.patch,
 from what I gather (at least it fixes it for me).
