[The static build of binutils is what gets the lto involved.] On 2018-Apr-7, at 5:29 PM, Mark Millard <marklmi26-fbsd at yahoo.com> wrote:

I had forgotten but I'd analyzed this once before: https://lists.freebsd.org/pipermail/freebsd-ports/2017-August/109769.html and it traced back to: STATIC=on: Build static executables and/or libraries for aarch64-binutils. (Static was at the time required for a poudriere/qemu mix that used aarch64-binutils.) (I do-not/did-not see such problems for powerpc64 targeted cross builds using xtoolchain material, such as powerpc64-binutils and powerpc64-gcc. This is specific to aarch64 for some reason.) So I'll see about turning STATIC off to enable buildworld. === Mark Millard marklmi26-fbsd at yahoo.com ( dsl-only.net went away in early 2018-Mar) _______________________________________________ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
