When starting Lyx it immediately crashes with the only message "Segmentation fault". Lyx was updated from V1.4.1 to V1.4.2 this week on my weekly emerge --sync; emerge --update --deep world. The compilation produced "a million warnings" about a wrong compiler version with a ref to gcc.hpp issued by boost. Now I am at gcc V4.1.1 and it seems that the boost-system expects to compile lyx with a version <V4.0. It is a disaster for me to be without Lyx. Please advice! Reproducible: Always Steps to Reproduce: 1. qt has been compiled with the USE-flag qt3support the gcc is at V4.1.1 2. emerge lyx (compiles V1.4.2, boost is at 1.33.1-r1 3. lyx (and immediate seg fault) lyx -dbg (same result) lyx -v (same result) Actual Results: lyx crashes Expected Results: it should have worked ;-) I have tried taking lyx out. Unmerged it. Then compiled in the traditional ./configure; make; make install procedure. The results were the same. I have tried to "downgrade" to V1.4.1 but here I get the recently reported "ACCESS DENIED" bug. I have tried to find a precompiled binary of lyx in order to try that, but I haven't found any. localhost ~ # emerge info *** Deprecated use of action 'info', use '--info' instead Portage 2.1.2-r9 (default-linux/x86/2006.0, gcc-4.1.1, glibc-2.5-r0, 2.6.19-gentoo-r5 i686) ================================================================= System uname: 2.6.19-gentoo-r5 i686 Intel(R) Pentium(R) M processor 1.60GHz Gentoo Base System release 1.12.9 Timestamp of tree: Mon, 19 Feb 2007 18:00:01 +0000 dev-java/java-config: 1.3.7, 2.0.31 dev-lang/python: 2.3.5-r3, 2.4.3-r4 dev-python/pycrypto: 2.0.1-r5 sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.13, 2.61 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: 2.16.1-r3 sys-devel/gcc-config: 1.3.14 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.17-r2 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CBUILD="i686-pc-linux-gnu" CFLAGS="-march=pentium-m -O2 -pipe -fomit-frame-pointer" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.3/env /usr/kde/3.3/share/config /usr/kde/3.3/shutdown /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/share/X11/xkb /usr/share/config" CONFIG_PROTECT_MASK="/etc/env.d /etc/env.d/java/ /etc/gconf /etc/java-config/vms/ /etc/revdep-rebuild /etc/terminfo /etc/texmf/web2c" CXXFLAGS="-march=pentium-m -O2 -pipe -fomit-frame-pointer" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig distlocks metadata-transfer sandbox sfperms strict" GENTOO_MIRRORS="http://www.mirrorservice.org/sites/www.ibiblio.org/gentoo/ ftp://ftp.mirrorservice.org/sites/www.ibiblio.org/gentoo/ http://mirror.uni-c.dk/gentoo/ http://mirror.gentoo.no/" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --compress --force --whole-file --delete --delete-after --stats --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X alsa apache2 apm arts berkdb bitmap-fonts cli cracklib crypt cups dlloader dri eds emboss encode esd firebird foomaticdb fortran gdbm gnome gpm gstreamer gtk gtk2 iconv imlib ipv6 isdnlog jpeg libg++ libwww mad midi mikmod motif mp3 mpeg mysql ncurses nls nptl nsplugin ogg opengl oss pam pcre perl png postgresql pppd python qt3 qt4 quicktime readline reflection sdl session spell spl ssl tcltk tcpd truetype truetype-fonts type1-fonts vorbis x86 xml xml2 xorg xv 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 mulaw multi null plug rate route share shm softvol" ELIBC="glibc" INPUT_DEVICES="keyboard mouse" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" USERLAND="GNU" VIDEO_CARDS="fbdev radeon vesa" Unset: CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, LINGUAS, PORTAGE_RSYNC_EXTRA_OPTS, PORTDIR_OVERLAY localhost ~ #
