>>> Failed to emerge net-dns/unbound-1.4.6, Log file: >>> '/home/build/portage/net-dns/unbound-1.4.6/temp/build.log' Reproducible: Sometimes Steps to Reproduce: # emerge -v ldns unbound [ebuild R ] net-libs/ldns-1.6.5 USE="python ssl vim-syntax -doc -lib32" 0 kB [ebuild U ] net-dns/unbound-1.4.6 [1.4.5] USE="python threads -debug -lib32 -static -test" 0 kB (lib32 comes from the modified portage from the multilib overlay, please ignore it) Actual Results: Failed to emerge due to a race condition. Unfortunately, I erased the failed log while trying to determine whether the bug is reproducible, but it involved a header file being changed while copying. And in the successful build log I see: make[1]: Entering directory `/home/build/portage/net-dns/unbound-1.4.6/work/unbound-1.4.6/ldns-src' ./install-sh -c -m 644 ldns/error.h ./include/ldns/ ./install-sh -c -m 644 ldns/error.h ./include/ldns/ ./install-sh -c -m 644 ldns/error.h ./include/ldns/ ./install-sh -c -m 644 ldns/packet.h ./include/ldns/ ./install-sh -c -m 644 ldns/packet.h ./include/ldns/ i.e. some headers are indeed copied more than once, which explains this race condition. And BTW, it should not use the bundled ldns library, so please investigate why the system one is not good enough. Since the standalone ldns library build process doesn't attempt to copy headers more than once, it may be sufficient to cause it to be used again. Expected Results: Emerged successfully even with -j3, using the system ldns library. # emerge --info Portage 2.2_rc67-r8 (default/linux/amd64/10.0/desktop, gcc-4.4.4, glibc-2.11.2-r0, 2.6.34-gentoo-r2 x86_64) ================================================================= System uname: Linux-2.6.34-gentoo-r2-x86_64-Intel-R-_Core-TM-2_CPU_6420_@_2.13GHz-with-gentoo-2.0.1 Timestamp of tree: Sat, 07 Aug 2010 02:15:01 +0000 app-shells/bash: 4.1_p7 dev-java/java-config: 2.1.11 dev-lang/python: 2.6.5-r3, 3.1.2-r4 dev-util/cmake: 2.8.1-r2 sys-apps/baselayout: 2.0.1 sys-apps/openrc: 0.6.1-r1 sys-apps/sandbox: 2.2 sys-devel/autoconf: 2.13, 2.65-r1 sys-devel/automake: 1.8.5-r4, 1.9.6-r3, 1.10.3, 1.11.1 sys-devel/binutils: 2.20.1-r1 sys-devel/gcc: 4.4.4-r1 sys-devel/gcc-config: 1.4.1 sys-devel/libtool: 2.2.10 virtual/os-headers: 2.6.34 ACCEPT_KEYWORDS="amd64 ~amd64" ACCEPT_LICENSE="*" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -march=core2 -fomit-frame-pointer -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/share/X11/xkb /var/bind /var/lib/hsqldb" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/eselect/postgresql /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo /etc/texmf/language.dat.d /etc/texmf/language.def.d /etc/texmf/updmap.d /etc/texmf/web2c" CXXFLAGS="-O2 -march=core2 -fomit-frame-pointer -pipe" DISTDIR="/home/distfiles" FEATURES="assume-digests buildpkg distlocks fixpackages news parallel-fetch preserve-libs protect-owned sandbox sfperms strict unmerge-logs unmerge-orphans userfetch" GENTOO_MIRRORS="http://mirror.yandex.ru/gentoo-distfiles http://distfiles.gentoo.org http://www.ibiblio.org/pub/Linux/distributions/gentoo" LANG="ru_RU.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" MAKEOPTS="-j3" PKGDIR="/home/packages/amd64" 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="/home/build" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage /var/lib/layman/multilib /var/lib/layman/java-overlay /usr/local/portage" SYNC="rsync://mirror.yandex.ru/gentoo-portage" USE="X a52 aac acl acpi alsa amd64 amr applet archive artworkextra automount bash-completion berkdb bidi bluetooth bzip2 cairo caps cdda cddb cdr cjk cli consolekit cracklib crypt css cups cxx dbus dirac djvu dri dts dvb dvd dvdr emboss encode exif faac faad fastcgi ffmpeg firefox flac fontconfig fortran fuse gcj gdbm gif gimp glibc-omitfp gnuplot gphoto2 gsm gtk iconv icq idn ieee1394 ipod ipv6 jabber jack jack-midi jbig jingle jpeg jpeg2k ladspa lame latex lcms ldap libsamplerate mad mikmod mmx mmxext mng modules mozilla mp3 mp4 mpeg mplayer mudflap multilib musepack ncurses nls nocd nptl nptlonly nsplugin ogg opengl openmp pam pango pch pcre pdf perl png policykit ppds pppd python qt3support raw rdesktop readline reflection samba scanner schroedinger sdl session shorten smp speex spell spl sse sse2 sse3 ssl ssse3 startup-notification svg symlink sysfs tcl tcpd theora threads tiff tk truetype unicode usb v4l2 videos vim-syntax vnc vorbis vpx wifi winbind wmf x264 xattr xcb xcomposite xinerama xml xmp xorg xulrunner xv xvid zlib" 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" DVB_CARDS="tda10046lifeview" ELIBC="glibc" INPUT_DEVICES="evdev synaptics keyboard mouse" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LIRC_DEVICES="devinput audio_alsa inputlirc" RUBY_TARGETS="ruby18" SANE_BACKENDS="gt68xx" USERLAND="GNU" VIDEO_CARDS="intel" 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, FFLAGS, INSTALL_MASK, LC_ALL, LINGUAS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS
This is quite an old version and I cannot reproduce with the latest version. Mind re-opening this report if it happens on unbound-1.4.17? Thanks.
I rebuilt it several times with MAKEOPTS=-j5, no failure. So let's consider this fixed.
