[Pkg-acpi-devel] Bug#701236: acpid: ftbfs with GCC-4.8

[Matthias Klose]

Package: src:acpid
Version: 1:2.0.18-1
Severity: important
Tags: sid jessie
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-4.8

The package fails to build in a test rebuild on at least amd64 with
gcc-4.8/g++-4.8, but succeeds to build with gcc-4.7/g++-4.7. The
severity of this report may be raised before the jessie release.

libnetlink.c:45:23: error: argument to 'sizeof' in 'memset' call is the same expression as the destination; did you mean to dereference it? [-Werror=sizeof-pointer-memaccess]

The full build log can be found at:
http://people.debian.org/~doko/logs-20130217/gcc48/acpid_2.0.18-1_unstable_gcc48.log
The last lines of the build log are at the end of this report.

To build with GCC 4.8, either set CC=gcc-4.8 CXX=g++-4.8 explicitly,
or install the gcc, g++, gfortran, ... packages from experimental.

apt-get -t experimental install g++-4.7 g++-4.8 libc6-dev

The test rebuild was done with eglibc-2.17 and GCC-4.8, so some issues
might be caused by the updated glibc.
