C++14 was enabled in PCH file but is currently disabled

ROOT

Dear ROOT-Team,
I’m trying to learn ROOT and I would like to install it with c++14 support,
unfortunately it doesn’t seems to get activated. Its a build from source and
AFAIK all dependencies needed for c++14 are installed (?):

OS-System is a Debian Stretch:
ci@r5:~/Prog/ROOT6/root$ uname -a
Linux r5 4.0.0-2-rt-amd64 #1 SMP PREEMPT RT Debian 4.0.8-1 (2015-07-11) x86_64 GNU/Linux

gcc:
ci@r5:~/Prog/ROOT6/root$ gcc --version
gcc (Debian 4.9.3-1) 4.9.3

clang:
ci@r5:~/Prog/ROOT6/root$ clang --version
clang version 3.7.0 (root.cern.ch/git/llvm.git 4f6e66a29b11d6c6398f7e8cfa90356d07c1036a)
Target: x86_64-unknown-linux-gnu

ROOT-config (see ‘configure.output.txt’ and ‘config.log.txt’ ):

ROOT-build (see ‘make.output.txt’):
make -j6

Some more info (after checking ‘make.output.txt’). There are errors during compilation:

Try with CMake. You can enable c++14 with -Dcxx14=ON
