When trying to emerge the latest gst-plugins-0.8.12, the process fails at the linking step. First, there is a warning issued: *** Warning: Linking the executable channelmixtest against the loadable module *** libgstaudioconvert.so is not portable! And then ld reports undefined references to symbols in ./../.libs/libgstaudioconvert.so: gst_audio_get_channel_positions and others. (I can reproduce the exact error if anyone actually is interested in resolving this) Disabling LDFLAGS="-Wl,-O1, -Wl,--as-needed, -Wl,--hash-style=both" in make.conf makes the problem go away. Not that this is critical, but stops e.g. the emerge world so it's a pain. Below is the output of emerge --info: Portage 2.1.2_pre3-r1 (default-linux/x86/2006.0, gcc-4.1.1, glibc-2.5-r0, 2.6.17 i686) ================================================================= System uname: 2.6.17 i686 Intel(R) Pentium(R) M processor 1600MHz Gentoo Base System version 1.12.5 Last Sync: Sat, 14 Oct 2006 16:50:01 +0000 distcc 2.18.3 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [enabled] ccache version 2.4 [enabled] app-admin/eselect-compiler: [Not Present] dev-java/java-config: 1.3.7, 2.0.30 dev-lang/python: 2.2.3-r6, 2.3.5, 2.4.3-r4 dev-python/pycrypto: 2.0.1-r5 dev-util/ccache: 2.4-r6 dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.60 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.17.50.0.5 sys-devel/gcc-config: 1.3.13-r3 sys-devel/libtool: 1.5.20-r1 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=pentium-m -O3 -msse2 -mfpmath=sse -fomit-frame-pointer -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.3/env /usr/kde/3.3/share/config /usr/kde/3.3/shutdown /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/X11/xkb /usr/share/config" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/gconf /etc/java-config/vms/ /etc/revdep-rebuild /etc/splash /etc/terminfo" CXXFLAGS="-march=pentium-m -O3 -msse2 -mfpmath=sse -fomit-frame-pointer -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig ccache distcc distlocks metadata-transfer sandbox sfperms strict" GENTOO_MIRRORS="<your_mirror_here> http://gentoo.osuosl.org http://www.ibiblio.org/pub/Linux/distributions/gentoo" LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--hash-style=both" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/overlays/qt-copy /usr/local/overlays/xgl-coffee /usr/local/portage" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="x86 X alsa apache2 apm arts berkdb bitmap-fonts cli crypt cups dlloader dri dvd eds elibc_glibc emboss encode esd fb foomaticdb fortran gdbm gif gnome gpm gstreamer gtk gtk2 hashstyle imlib input_devices_evdev input_devices_joystick input_devices_keyboard input_devices_mouse input_devices_synaptics ipv6 isdnlog jpeg kde kdeenablefinal kdehiddenvisibility kernel_linux libg++ libwww lirc_devices_imon lirc_devices_irman lirc_devices_sir mad mikmod motif mp3 mpeg ncurses nls nptl ogg opengl oss pam pcre perl png pppd python qt3 qt4 quicktime readline reflection sdl session spell spl ssl tcpd truetype truetype-fonts type1-fonts udev userland_GNU video_cards_ati video_cards_vesa video_cards_vga video_cards_vmware vorbis xinerama xml xmms xorg xv zlib" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LINGUAS, PORTAGE_RSYNC_EXTRA_OPTS
hash-style is not a supported LDFLAG, please report this upstream. Thanks.
