When emerging electricsheep-2.4 with gcc-3.3.1, the build stops with an error when compiling "video_out_x11.o". Reproducible: Always Steps to Reproduce: 1. emerge electricsheep 2.

ERROR: x11-misc/electricsheep-2.4 failed. !!! Function src_compile, Line 377, Exitcode 2 !!! emake failed Expected Results: The build should continue, possibly with warnings, but should not stop. The reason why the ebuild stops is that warnings generated by the compiler are treated as errors with the -Werror switch to gcc in the electricsheep-2.4/mpeg2dec subdirectory. When editing the configure script not to use -Werror the build completes (and electricsheep works, apparently without problems), however, not being sure whether a patch to the relevant files (electricsheep-2.4/mpeg2dec/{configure,configure.in} would be the proper solution or if this is something that should be solved upstream, I merely report the error and give the relevant information. emerge info: Portage 2.0.49-r7 (default-x86-1.4, gcc-3.3.1, glibc-2.3.2-r1, 2.4.20-gentoo-r7)================================================================= System uname: 2.4.20-gentoo-r7 i686 Pentium III (Katmai) ACCEPT_KEYWORDS="x86 ~x86" AUTOCLEAN="yes" CFLAGS="-march=pentium3 -O3 -fomit-frame-pointer -pipe" CHOST="i686-pc-linux-gnu" COMPILER="gcc3" CONFIG_PROTECT="/etc /var/qmail/control /usr/share/config /usr/kde/2/share/config /usr/kde/3/share/config /usr/X11R6/lib/X11/xkb /usr/share/texmf/tex/generic/config/ /usr/share/texmf/tex/platex/config/" CONFIG_PROTECT_MASK="/etc/afs/C /etc/afs/afsws /etc/gconf /etc/env.d" CXXFLAGS="-march=pentium3 -O3 -fomit-frame-pointer -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="ccache autoaddcvs sandbox userpriv usersandbox fixpackages" GENTOO_MIRRORS="http://trumpetti.atm.tut.fi/gentoo/ http://mirror.pudas.net/gentoo http://www.fhh.opensource-mirror.de/gentoo.org/ http://mirrors.sec.informatik.tu-darmstadt.de/gentoo http://gentoo.mirror.sdv.fr http://ftp.belnet.be/mirror/rsync.gentoo.org/gentoo/ http://ftp.snt.utwente.nl/pub/os/linux/gentoo http://ftp.gentoo.skynet.be/pub/gentoo/ http://linux.rz.ruhr-uni-bochum.de/download/gentoo-mirror/ http://gentoo.inode.at/ http://gentoo.linux.no/ http://ftp.easynet.nl/mirror/gentoo/ http://darkstar.ist.utl.pt/gentoo/ ftp://trumpetti.atm.tut.fi/gentoo/ http://adelie.polymtl.ca/ http://gentoo.noved.org/ http://mirrors.tds.net/gentoo http://ftp.rhnet.is/pub/gentoo/ ftp://ftp.fhh.opensource-mirror.de/pub/gentoo.org/ ftp://mirror.pudas.net/gentoo" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="x86 oss avi crypt cups encode foomaticdb gif jpeg libg++ mad mikmod mmx mpeg ncurses nls pdflib png quicktime spell truetype xml2 xmms xv zlib directfb alsa gdbm berkdb slang readline tetex aalib bonobo svga ggi tcltk java guile ruby mysql X sdl gpm tcpd pam libwww ssl perl python esd imlib oggvorbis gnome gtk qt motif opengl mozilla ldap cdr 3ds acl acpi acpi4linux afs autofs clamav cscope curl dga dnd doc dv dvb dvd emacs ethereal faad fbcon fbdev flash fltk fluidsynth gd gnomedb gphoto2 gstreamer gtk2 gtkhtml imap ipv6 jack jack-tmpfs junit ladcca lcms libgda maildir mbox mcal md5sum memlimit mng moznocompose moznoirc mozsvg mpi music oav objc odbc offensive openal plotutils rage128 rplay samba sasl snmp socks5 sox sse tiff transcode type1 usb v4l vim-with-x wmf wxwindows X509 Xaw3d xfs xinerama xvid -apm -arts -kde"
fixed in cvs ... i just ended up sed-ing out Werror from the configure script and sending an e-mail to the upstream author (i've talked to him before so it shouldnt be a problem there)
