Package: gcc-8 Version: 8.2.0-14 Severity: important Dear Maintainer,
Probably gcc-8 should be in conflict with binutils-x86-64-linux-gnu:i386 because of the following chain of events: - install an unstable amd64 system - enable multiarch i386 - install gcc-8 - install binutils-x86-64-linux-gnu:i386 => This will (because of a conflict) uninstall binutils-x86-64-linux-gnu Now the compiler is broken with this message: /usr/lib/gcc/x86_64-linux-gnu/8/../../../../x86_64-linux-gnu/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/8/liblto_plugin.so: error loading plugin: /usr/lib/gcc/x86_64-linux-gnu/8/liblto_plugin.so: mauvaise classe ELF : ELFCLASS64 This is because the plugin /usr/lib/gcc/x86_64-linux-gnu/8/liblto_plugin.so is installed by gcc-8 (it is an amd64 executable) but is loaded by ld. Since we can independently install the 32-bit version of the binutils, now we have a 32-bit executable loading a 64-bit library. I am not sure what is the proper fix but clearly it should be impossible to install the 32-bit version of binutils with the 64-bit version of gcc-8 because of this plugin. This probably explains bug #916603 (with gcc-6 instead of gcc-8). Note that it may be strange to install binutils-x86-64-linux-gnu:i386 but somehow APT decided to do it on its own at some point and I did not notice so this can happen automatically. -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8), LANGUAGE=fr (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages gcc-8 depends on: ii binutils 2.31.1-11 ii cpp-8 8.2.0-14 ii gcc-8-base 8.2.0-14 ii libc6 2.28-5 ii libcc1-0 8.2.0-14 ii libgcc-8-dev 8.2.0-14 ii libgcc1 1:8.2.0-14 ii libgmp10 2:6.1.2+dfsg-4 ii libisl19 0.20-2 ii libmpc3 1.1.0-1 ii libmpfr6 4.0.2~rc1-1 ii libstdc++6 8.2.0-14 ii zlib1g 1:1.2.11.dfsg-1 Versions of packages gcc-8 recommends: ii libc6-dev 2.28-5 Versions of packages gcc-8 suggests: pn gcc-8-doc <none> pn gcc-8-locales <none> ii gcc-8-multilib 8.2.0-14 pn libasan5-dbg <none> pn libatomic1-dbg <none> pn libgcc1-dbg <none> pn libgomp1-dbg <none> pn libitm1-dbg <none> pn liblsan0-dbg <none> pn libmpx2-dbg <none> pn libquadmath0-dbg <none> pn libtsan0-dbg <none> pn libubsan1-dbg <none> -- no debconf information
