Upon compiling Qt of the specified version, using distcc, there occurred fatal compilation errors ("undefined [references] to", amongst other things, sjlj related things). I have noticed the same _Unwind_SjLj_* referencing errors in at least one other compile (I believe it was libmp4v2). The interesting thing to note here, is that it is not reproducable when compiling only locally (i.e., sans distcc). Thus, perhaps it would be worth flagging such compiles, to be done without the assitance of distcc, but again, only if such is generally the case. If you would like more information, please do not hesitate to ask. (GCC version: 4.1.2 -- across all distcc nodes) Reproducible: Always Steps to Reproduce: 1. remotely, setup a distcc server -- with as much closeness, in compiler version and other things, to the setup of the node in question, as you like 2. emerge =qt-4.3.4 Actual Results: Compilation errors, as reported in the build log. Expected Results: Compilation success. emerge info: Portage 2.1.4.4 (default-linux/x86/2007.0/desktop, gcc-4.1.2, glibc-2.6.1-r0, 2. 6.22.2 i686) ================================================================= System uname: 2.6.22.2 i686 Intel(R) Pentium(R) 4 CPU 2.40GHz Timestamp of tree: Sun, 16 Mar 2008 11:00:01 +0000 distcc 2.18.3 i686-pc-linux-gnu (protocols 1 and 2) (default port 3632) [enabled ] ccache version 2.4 [enabled] app-shells/bash: 3.2_p17-r1 dev-java/java-config: 1.3.7, 2.1.5 dev-lang/python: 2.5.1-r5 dev-python/pycrypto: 2.0.1-r6 dev-util/ccache: 2.4-r7 sys-apps/baselayout: 1.12.11.1 sys-apps/sandbox: 1.2.18.1-r2 sys-devel/autoconf: 2.13, 2.61-r1 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r2, 1.10 sys-devel/binutils: 2.18-r1 sys-devel/gcc-config: 1.4.0-r4 sys-devel/libtool: 1.5.26 virtual/os-headers: 2.6.24 ACCEPT_KEYWORDS="x86" CBUILD="i686-pc-linux-gnu" CFLAGS="-O2 -mtune=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/shu tdown /usr/share/config /var/bind" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/fonts/fonts.conf /etc/gcon f /etc/init.d /etc/revdep-rebuild /etc/terminfo /etc/texmf/web2c /etc/udev/rules .d" CXXFLAGS="-O2 -mtune=i686 -pipe" DISTDIR="/home/ports/portage/distfiles" FEATURES="ccache distcc distlocks metadata-transfer sandbox sfperms strict unmer ge-orphans userfetch" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/linux/ distributions/gentoo" LINGUAS="en" MAKEOPTS="-j7" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude='/d istfiles' --exclude='/local' --exclude='/packages'" PORTAGE_TMPDIR="/home/ports/varTMP" PORTDIR="/home/ports/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X acl acpi alsa berkdb cairo caps cdr cli cracklib crypt cups dbus dri dvd dvdr dvdread eds emboss encode evo fam firefox fortran gdbm gif glitz gpm gstrea mer gtk hal iconv imap isdnlog jpeg kerberos libwww lm_sensors mad maildir midi mikmod mmx mozilla mp3 mpeg mudflap ncurses nls no-helpbrowser nptl nptlonly nsp lugin nvidia offensive ogg opengl openmp oss pam pcre pdf perl pic png pppd pyth on qt3support quicktime readline reflection sasl scanner sdl session skey spl ss e sse2 ssl svg tcpd tiff truetype unicode usb vorbis win32codecs x86 xml xorg xs creensaver xv zlib zsh" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca 0106 cmipci emu10k1 emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel 8x0 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 mulaw multi null plug rate route share shm so ftvol" APACHE2_MODULES="actions alias auth_basic authn_alias authn_anon authn_db m authn_default authn_file authz_dbm authz_default authz_groupfile authz_host au thz_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 m em_cache mime mime_magic negotiation rewrite setenvif speling status unique_id u serdir usertrack vhost_alias" ELIBC="glibc" INPUT_DEVICES="keyboard mouse" KERNE L="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LINGUAS="en" USERLAND="GNU" VIDEO_CARDS="nvidia" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFL AGS, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR _OVERLAY
Created attachment 146432 [details] Build Log for Qt-4.3.4, using distcc See attachment description, and most importantly, bug file description.
You have USE=pch enabled for QT?
(In reply to comment #2) > You have USE=pch enabled for QT? > No, I do not (I've seen the bug related to that comment -- it does not seem to apply). As an update, I'd also like to note that *any* build involving the same calls (_Unwind_SjLj_* being the most prominent), has the exact same problems, when compiling with distcc. I.e., such is true for hplip (latest stable version, as I just tried), PyQt, et al..
Created attachment 146454 [details] hplip build log showing similar errors during compilation with distcc Just an update, to show the generality of this problem. Perhaps the severity level is understated.
Building any qt-* related packages now fails using distcc feature. Quick hack to avoid compilation problems is to use: # FEATURES="-ccache -distcc" emerge qt-(remainder_of_package_name)
Is this still valid with updated systems?
Unknown here. I have yet to reinstall distcc and I try to avoid all QT/KDE related stuff.
qt metapackage is no longer in portage tree. Is this still valid with 4.8.0?
