I upgraded to sys-devel/gcc-4.6.0_alpha20110219 and emerged system+world with it. Only compilation errors I got were with sys-apps/diffutils, sys-libs/glibc, app-arch/arj, sys-apps/net-tools, media-gfx/exiv2 but after an update of these packages compilation went fine (sys-apps/diffutils-3.0, sys-libs/glibc-2.13-r1, app-arch/arj-3.10.22-r3, sys-apps/net-tools-1.60_p20100815160931, media-gfx/exiv2-0.21-r1 compile with no issues with gcc-4.6.0). Once it was xulrunner's turn the compilation failed with a couple of trivial errors. Reproducible: Always Steps to Reproduce: 1.Get the latest gcc-4.6.0 alpha (I have the sys-devel/gcc-4.6.0_alpha20110219) 2.Emerge system+world with it (optional maybe?) 3.Emerge net-libs/xulrunner-1.9.2.13 or newer. Actual Results: net-libs/xulrunner-1.9.2.13 fails with an 'uninitialized const' and other. Expected Results: net-libs/xulrunner should have compiled and installed without issues. But it didn't. emerge --info Portage 2.2.0_alpha25 (default/linux/amd64/10.0/desktop, gcc-4.6.0-alpha20110219, glibc-2.13-r1, 2.6.37-tuxonice x86_64) ================================================================= System uname: Linux-2.6.37-tuxonice-x86_64-Intel-R-_Core-TM-_i7-2600K_CPU_@_3.40GHz-with-gentoo-1.12.14 Timestamp of tree: Tue, 01 Mar 2011 19:45:01 +0000 app-shells/bash: 4.1_p9 dev-java/java-config: 2.1.11-r3 dev-lang/python: 2.6.6-r2, 3.1.3-r1 dev-util/cmake: 2.8.1-r2 sys-apps/baselayout: 1.12.14-r1 sys-apps/sandbox: 2.4 sys-devel/autoconf: 2.13, 2.65-r1 sys-devel/automake: 1.9.6-r3, 1.10.3, 1.11.1 sys-devel/binutils: 2.20.1-r1 sys-devel/gcc: 4.6.0_alpha20110219::toolchain sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.10 sys-devel/make: 3.81-r2 virtual/os-headers: 2.6.36.1 (sys-kernel/linux-headers) Repositories: gentoo toolchain mozilla local_overlay Installed sets: ACCEPT_KEYWORDS="amd64" ACCEPT_LICENSE="* -@EULA" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=native -O2 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo" CXXFLAGS="-march=native -O2 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="assume-digests binpkg-logs distlocks fixlafiles fixpackages news parallel-fetch preserve-libs protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch" FFLAGS="" GENTOO_MIRRORS="http://mirrors.linuxant.fr/distfiles.gentoo.org/ ftp://mirrors.linuxant.fr/distfiles.gentoo.org/ ftp://mirror.ovh.net/gentoo-distfiles/ http://mirror.ovh.net/gentoo-distfiles/" LANG="en_GB.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" LINGUAS="en_GB en_US en de fr" MAKEOPTS="-j8" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/var/lib/layman/toolchain /var/lib/layman/mozilla /usr/local/portage" SYNC="rsync://rsync.fr.gentoo.org/gentoo-portage" USE="X a52 aac acl acpi alsa amd64 apm atm avahi bash-completion berkdb branding bzip2 cairo cdda cddb cdr cli consolekit cracklib crypt css cups cxx dbus dri dts dv dvd dvdr emboss encode exif fam fbcon ffmpeg firefox flac fontconfig fortran gdbm gdu gif gimp gmp gnutls gpm gstreamer gtk gzip iconv ieee1394 ipv6 jpeg jpeg2k lcms ldap libnotify lm_sensors lock lzma lzo mad matroska mikmod mmx mng modules mp3 mp4 mpeg mudflap multilib musepack musicbrainz ncurses networkmanager nls nptl nptlonly nvidia ogg openal opengl openmp pam pango pcre pdf perl pmu png policykit posix ppds pppd python qt3support raw readline samba sdl session slp smp speex spell sse sse2 sse3 ssl ssse3 startup-notification svg sysfs szip tcpd theora threads thunar tiff truetype udev unicode usb vdpau vorbis wavpack wmf x264 xattr xcb xcomposite xinerama xml xorg xpm xscreensaver xv xvid zeroconf zlib zsh-completion" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" ALSA_PCM_PLUGINS="adpcm alaw asym copy dmix dshare dsnoop empty extplug file hooks iec958 ioplug ladspa lfloat linear meter mmap_emul mulaw multi null plug rate route share shm softvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" CAMERAS="ptp2" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ubx" INPUT_DEVICES="evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="en_GB en_US en de fr" PHP_TARGETS="php5-3" RUBY_TARGETS="ruby18" USERLAND="GNU" VIDEO_CARDS="nvidia" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
Created attachment 264539 [details] The build.log with the error
Created attachment 264541 [details, diff] A Patch I created and that fixed the errors for me. Goes into net-libs/xulrunner/files/ This post: http://lists.fedoraproject.org/pipermail/devel/2011-February/148523.html was very helpful in determining the cause quickly. I just added default constructors to the classes gcc complained about and included <cstddef> in one file. GCC-4.6.0 seems to be stricter about those. With the patch the package emerged fine.
Created attachment 264543 [details] The original ebuild with just the patch line added. I added a single line for the patch to be used.
When 4.6.0 is officially released we will worry about this.
