So I'm happy with the new USE flag dep thing, where portage bombs out if a depended package doesn't have the correct USE flag enabled _before_ it tries to compile. However, today I did my usual: $ sudo emerge -vauDN world but got this: These are the packages that would be merged, in order: Calculating dependencies... done! emerge: there are no ebuilds built with USE flags to satisfy ">=media-libs/win32codecs-20071007-r4[real]". !!! One of the following packages is required to complete your request: - media-libs/win32codecs-20071007-r4 (Change USE: +real) (dependency required by "media-libs/realcodecs-11.0.1.1056" [ebuild]) * GNU info directory index is up-to-date. Hm, ok great, so realcodecs wants win32codecs compiled with the real USE flag. Well, what is pulling in realcodecs? Oh, I can't tell anymore because emerge just displays this error and exits! `emerge -uva world` works, `emerge -uvaD world` doesn't... Ideally it should still display the emerge list and error, like it does for a blockage... How else do I know what is pulling in realcodecs? (Without out using other tools). Thanks for taking the time to read my suggestion :) $ emerge --info Portage 2.2_rc12 (default/linux/x86/2008.0, gcc-4.1.2, glibc-2.8_p20080602-r0, 2.6.26-tuxonice i686) ================================================================= System uname: Linux-2.6.26-tuxonice-i686-Intel-R-_Core-TM-2_Duo_CPU_T9500_@_2.60GHz-with-glibc2.0 Timestamp of tree: Mon, 03 Nov 2008 03:20:01 +0000 ccache version 2.4 [disabled] app-shells/bash: 3.2_p39 dev-java/java-config: 1.3.7, 2.1.6-r1 dev-lang/python: 2.4.4-r6, 2.5.2-r8 dev-python/pycrypto: 2.0.1-r6 dev-util/ccache: 2.4-r8 dev-util/cmake: 2.6.2 sys-apps/baselayout: 2.0.0 sys-apps/openrc: 0.3.0-r1 sys-apps/sandbox: 1.2.18.1-r3 sys-devel/autoconf: 2.13, 2.63 sys-devel/automake: 1.4_p6, 1.5, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10.1-r1 sys-devel/binutils: 2.18-r4 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 2.2.6a virtual/os-headers: 2.6.27-r2 ACCEPT_KEYWORDS="x86 ~x86" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -march=i686 -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/share/config" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/php/apache2-php5/ext-active/ /etc/php/cgi-php5/ext-active/ /etc/php/cli-php5/ext-active/ /etc/revdep-rebuild /etc/splash /etc/terminfo /etc/texmf/web2c /etc/udev/rules.d" CXXFLAGS="-O2 -march=i686 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="distlocks fixpackages parallel-fetch preserve-libs protect-owned sandbox sfperms strict unmerge-orphans userfetch userpriv usersandbox" GENTOO_MIRRORS="ftp://morpheus.pcorp.com.au/pub/gentoo-portage/ http://mirror.internode.on.net/pub/gentoo/ http://ftp.swin.edu.au/gentoo/" LANG="en_AU" LC_ALL="en_AU" LDFLAGS="-Wl,-O1" LINGUAS="en_AU en en_GB en_US" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" 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="/usr/local/portage/layman/desktop-effects /usr/local/portage /usr/local/portage-synce-overlay" SYNC="rsync://rsync.au.gentoo.org/gentoo-portage" USE="X aac acl acpi aiglx alsa avahi berkdb bzip2 cli cracklib crypt cups dbus dri esd ffmpeg fortran gdbm gnome gpm gtk hal iconv ipv6 isdnlog jpeg libnotify midi mpeg mudflap ncurses nls nptl nptlonly opengl openmp pam pcre perl pppd python readline reflection samba session smb spl ssl sysfs tcpd unicode x86 xcb xinerama xorg zlib" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1 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 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" ELIBC="glibc" INPUT_DEVICES="keyboard mouse synaptics evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="en_AU en en_GB en_US" USERLAND="GNU" VIDEO_CARDS="nv nvidia vesa fbdev" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, FFLAGS, INSTALL_MASK, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS

whoa, thanks for the fast one! Hm, the output is slightly different, but not what I would expect.

For more information about Blocked Packages, please refer to the following section of the Gentoo Linux x86 Handbook (architecture is irrelevant): http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?full=1#blocked IMHO it would make sense to show the list of packages to install, with some sort of blocker-like message against (in this case) "media-libs/realcodecs-11.0.1.1056" as realcodecs is blocked by a USE flag dependancy. thoughts? thanks.

But you guys know that...
Now I see what you want. We can do that by pruning off the part of the graph with unsatisfied dependencies, and continuing to build the rest of the graph. For example, due to the unsatisfied ">=media-libs/win32codecs-20071007-r4[real]" dependency, the final graph would exclude realcodecs, realplayer, and mplayer since they would all have unsatisfied dependencies.

It would be nice to see part of the graph, but I guess the point of showing the graph was so that one could see the whole dependency pull for win32codecs[real]. I guess though that your original patch from comment 1 does this, so perhaps I'm only being fussy with wanting to see the graph :) At least your current patch seems to look the same as when version dependencies aren't met (ie. I'm too aggressive in package.mask) - in which case the graph isn't shown either. So the patch works, some graph would be a bonus, but not necessary!
This is fixed in 2.2_rc14. (In reply to comment #5) > So the patch works, some graph would be a bonus, but not necessary! Ok, marking as fixed. You can file a separate feature enhancement but for the other thing if you want.
