[Debichem-devel] Bug#812265: avogadro: FTBFS with GCC 6: cmake failure

[Martin Michlmayr]

Package: avogadro
Version: 1.0.3-13
Severity: normal
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-6

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

Note: openbabel has the same issue
