Hi guys, when trying to compile btrfs-progs from the unstable repo (git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs-unstable.git) via the live-ebuild (on Gentoo) it keeps on failing for me no matter what (sane) CFLAGS or LDFLAGS I use: (for reference and completeness I'll also post the ebuild here to find out if it's a ebuild-related problem): ************************************************************************************************************************************************** # Copyright 1999-2010 Gentoo Foundation # Distributed under the terms of the GNU General Public License v2 # $Header: /var/cvsroot/gentoo-x86/sys-fs/btrfs-progs/btrfs-progs-9999.ebuild,v 1.13 2010/04/06 14:46:59 lavajoe Exp $ inherit eutils git DESCRIPTION="Btrfs filesystem utilities" HOMEPAGE="http://btrfs.wiki.kernel.org/"; SRC_URI="" LICENSE="GPL-2" SLOT="0" KEYWORDS="" IUSE="acl debug-utils" DEPEND="debug-utils?

-D_FORTIFY_SOURCE=2 if I remember correctly) but switching to the vanilla-behavior of gcc and disabling fortify via -U_FORTIFY_SOURCE & the default gentoo LDFLAGS also didn't help:
