Date: Mon, 10 Aug 2020 03:45:14 +0000 [thread overview]
Message-ID: <bug-26360-131@http.sourceware.org/bugzilla/> (raw)
https://sourceware.org/bugzilla/show_bug.cgi?id=26360
Bug ID: 26360
Summary: glibc 2.32 fails to crosscompile to ppc64le-linux-gnu
using gcc 10.2.0
Product: glibc
Version: 2.32
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: build
Assignee: unassigned at sourceware dot org
Reporter: bero at lindev dot ch
CC: carlos at redhat dot com
Target Milestone: ---
Trying to crosscompile glibc 2.32 with a ppc64le-linux-gnu-gcc 10.2.0
crosscompiler on an x86_64-linux-gnu fails.
If -Werror is enabled, it errors out on:
In file included from ../argp/argp.h:23,
from ../include/argp.h:2,
from ../sysdeps/ieee754/ldbl-opt/nldbl-compat.c:25:

Without -Werror, it gets past that point, but later on errors out saying
In file included from <command-line>:
../sysdeps/ieee754/ldbl-opt/nldbl-sscanf.c:22:23: error: ‘_IO_sscanf’ aliased

Other targets, including non-le ppc64-linux-gnu, compile fine.
