Bug ID: 28122
Summary: [gold] Use of deleted constructor with latest GCC
Product: binutils
Version: 2.38 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: msc at linux dot ibm.com
CC: ian at airs dot com
Target Milestone: ---
Building binutils with latest GCC causes issues when building gold.
Reproduced with:
arch: ppc64le
Using GCC: 8bf5b49ebd2176b8c535147377381dd07fbdd643
binutils: f878836265702be977ad9d1ea6d4fbdc4dac64cf
Steps to reproduce:
$ cd ~/build/gcc
$ ~/src/gcc/configure --prefix=/home/mscastanho/usr --enable-languages=c,c++
--with-glibc-version=2.33 --disable-bootstrap CC=gcc-11 CXX=g++-11 && make -j20
&> _make; make install
$ cd ~/build/binutils
$ myusr=/home/mscastanho/usr/; CC=${myusr}/bin/gcc CXX=${myusr}/bin/g++
CFLAGS="-g -O2 -Wno-error=array-bounds" CXXFLAGS="-g -O2"
~/src/binutils-gdb/configure --prefix=${myusr} --disable-gdb
--disable-gdbserver --disable-readline --disable-libdecnumber --disable-sim
--disable-nls --enable-shared --enable-plugins --enable-install-libiberty=./
--enable-gold --enable-follow-debug-links=no && make -j16
