--- Comment #7 from Martin Sebor <msebor at gcc dot gnu.org> ---
I also see these failures in my builds on x86_64-linux running Fedora 25 with
stock Binutils (GNU ld version 2.26.1-1.fc25
). The ld warning is the same:
/usr/bin/ld: /tmp/ccIHhHfL.lto.o: plugin needed to handle lto object
>From comment #6 it sounds like there are at least two options for how to deal
with these failures. Is there consensus on how to proceed? (I build on a
shared machine where I'm not sure I will be able to upgrade Binutils so I would
prefer some other alternative).
