Subject: Building gcc 12 cross-compiler with --enable-lto on FreeBSD fails
Date: Wed, 15 Jun 2022 19:25:18 +1000	[thread overview]
Message-ID: <bb1b6476-d3ab-a1da-a5bb-aad8c6958260@contemporary.net.au> (raw)

Hi,

I am trying to build a cross-compiler on FreeBSD with --enable-lto because a
chip vendor is using it when building controller software that is part of a system.

The build I am using symlinks gmp, mpfr etc as source so they are built as part
of the gcc build.

The mpfr package is reporting ...

build/mpfr/config.log:configure:17408: error: Link Time Optimisation is not
supported (see config.log for details).

Should the enable option be passed to these packages?

I have assumed the enable option for LTO is for the cross compiler and not the
host gcc?

Thanks
Chris
