This failure is most likely related to all your unsafe CFLAGS and LTO stuff: lto1: fatal error: bytecode stream in file '/usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../lib64/libiberty.a' generated with LTO version 8.0 instead of the expected 8.1 compilation terminated. lto-wrapper: fatal error: x86_64-pc-linux-gnu-gcc returned 1 exit status compilation terminated. /usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: error: lto-wrapper failed collect2: error: ld returned 1 exit status
Try rebuilding gcc then. And probably your whole system.
I have the same on two out of four boxes; they're quite identical afaik - one of the boxes work as a binhost and gcc on the three others is actually a binpkg from the binhost. Distcc builds on the binhost and on one of the others, on the two remaining I have same error: Cannot find libiberty. I've tried diff'ing the enviroment-log from a working and non-working machine. tor ~ # diff work_environ fail_environ 56d55 < declare -x DCC_EMAILLOG_WHOM_TO_BLAME="" 82d80 < declare -- ECONF_SOURCE="." 144d141 < declare -x NCURSES_NO_UTF8_ACS="1" 207c204 < declare -x SANDBOX_PREDICT="/var/tmp/portage/sys-devel/distcc-3.3.3/homedir:/dev/crypto" --- > declare -x SANDBOX_PREDICT="/var/tmp/portage/sys-devel/distcc-3.3.3/homedir:/dev/crypto:/var/cache/fontconfig" 215,217c212,214 < declare -x SSH_CLIENT="2001:470:28:4a6:7560:3a1a:f8cf:260f 61497 22" < declare -x SSH_CONNECTION="2001:470:28:4a6:7560:3a1a:f8cf:260f 61497 2001:470:28:4a6::7 22" < declare -x SSH_TTY="/dev/pts/0" --- > declare -x SSH_CLIENT="2001:470:28:4a6:7560:3a1a:f8cf:260f 61466 22" > declare -x SSH_CONNECTION="2001:470:28:4a6:7560:3a1a:f8cf:260f 61466 2001:470:28:4a6::6 22" > declare -x SSH_TTY="/dev/pts/1" 221d217 < declare -x UNCACHED_ERR_FD=""
Fixed for me by rebuilding sys-libs/binutils-libs.
This happend to me to today with sys-devel/distcc-3.3.3-r1 and Fixed for me by rebuilding sys-libs/binutils-libs. I have quite the same setup as Vladi but sys-devel/gcc/gcc-10.0.1_pre9999.
*** Bug 680248 has been marked as a duplicate of this bug. ***
I found this one trying install distcc on one of my LTO enabled 23.0 profile machines. It only seems to effect sys-devel/distcc when GCC has been updated but sys-libs/binutils-libs hasn't been rebuilt with that version when LTO is enabled on both packages. Best solution I have for this is to add a section to the wiki page as from testing it seems very rare to hit however all I have included all my findings in case anyone has a better solution or notices a wider issue this could cause. https://wiki.gentoo.org/wiki/Distcc#configure:_error:_Cannot_find_libiberty
