Bug#812295: vtk: FTBFS with GCC 6: cmake error

[Martin Michlmayr]

Package: vtk
Version: 5.10.1+dfsg-2
Severity: normal
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-6 gcc-6-unknown

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.

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
