Subject: android-platform-frameworks-native: FTBFS with GCC 6: redeclaration of C++ built-in type

Date: Tue, 19 Jan 2016 17:38:18 -0800

Package: android-platform-frameworks-native
Version: 21-3
Severity: important
User: debian-gcc@lists.debian.org
Usertags: ftbfs-gcc-6 gcc-6-redeclaration-builtin

This package fails to build with GCC 6.  GCC 6 has not been released
yet, but it's expected that GCC 6 will become the default compiler for
stretch.

Note that only the first error is reported; there might be more.  You
can find a snapshot of GCC 6 in experimental.  To build with GCC 6,
you can set CC=gcc-6 CXX=g++-6 explicitly.

You may be able to find out more about this issue at
https://gcc.gnu.org/gcc-6/changes.html

Control: tags + moreinfo

libutils is already moved to src:android-platform-system-core hence I
reassign this bug. However I haven't tested GCC 6 for the latest
libutils, but I guess it will fail too because I haven't use
"-fpermissive".

Subject: fixed upstream

This was fixed upstream, so the latest version of
android-platform-system-core fixed this.
