Bug ID: 32016
Summary: ld.gold error unsupported -mbss-plt code
Product: binutils
Version: 2.40
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: judge.packham+glibc at gmail dot com
CC: ian at airs dot com
Target Milestone: ---
I'm experimenting with adding ld.gold as an option to our toolchains
but I'm hitting an error. This happens to be from the lxcfs package
which tries to use ld.gold if it's available. This only seems to
affect our powerpc 32 builds. Other architectures seem fine.
I've tried with and without -mbss-plt in $CFLAGS. I'm not sure if this
is a compiler issue, linker issue or just a problem with the flags we
are passing
The error is

I don't really understand what ld.gold is complaining about. My
options right now are to not build that package for powerpc 32 or to
not have ld.gold available for powerpc 32. Both of those options
aren't too terrible but if it were a case of simply passing the right
arguments then having ld.gold available would be nicer.
