Description Luigi Baldoni 2019-07-22 12:38:16 UTC

This is what I see:
   clang-8.0: error: unsupported argument '1' to option 'flto='
rpm --eval %optflags shows in fact:
   -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection -flto=1 -g

Comment 1 Alynx Zhou 2019-07-23 01:43:16 UTC

I am not sure to which this bug belongs, `-flto` seems a new flag, maybe clang package has no support to it current? Anyway, please reassign if incorrect.

Comment 2 Richard Biener 2019-07-23 07:33:47 UTC

All packages are built with GCC.

That is, if you insist building things with clang just do

%define _lto_cflags %{nil}

in your %build section.
