[Python-modules-team] Bug#811669: FTBFS with GCC 6: cannot convert x to y

[Martin Michlmayr]

Package: shiboken
Version: 1.2.2-2
Severity: important
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-6 gcc-6-cannot-convert

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.
