scons seems to ignore the CC and CXX environment variables completely.
If I build klick with gcc/g++ from experimental I can reproduce the
FTBFS.

Hi,

I'm trying fix this issue
I added gcc-6 and g++-6 as build-deps and these lines to d/rules:
export CC = gcc-6
export CXX = g++-6

Not sure if I still missing something but package build fine this way...

best regards

Bug#812034: klick: FTBFS with GCC 6: needed for in-class initialization

[Martin Michlmayr]

Package: klick
Version: 0.12.2-2
Severity: important
User: debian-...@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
