kakoune: Can't build on Ubuntu 14.04.5

I’m trying to build on Ubuntu 14.04.5. Since the available version of GCC is 4.8.4, I installed clang 3.8 and I am compiling by doing CXX=clang++-3.8 make I think I have installed all dependencies.

However, when compiling, make spits out a lot of warning: unknown attribute 'optimize' ignored [-Wunknown-attributes] and finally stops on

command_manager.cc:466:16: error: no viable overloaded '='
            it = tokens.insert(tokens.erase(it),
            ~~ ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It looks like it’s using GCC 4.8 libraries? I am confused, since I am using clang-3.8 to compile. Am I doing something wrong?

GCC 5 is not available by default on Ubuntu 14.04. I solved the issue by following this guide:

Install this (official) PPA:

$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test

Update and upgrade:

$ sudo apt-get update && sudo apt-get dselect-upgrade

Install gcc-6 and g+±6:

$ sudo apt-get install gcc-6 g++-6

Compile with:

$ CXX=g++-6 make clean all

Now it compiles fine!

Please add the version requirement for libc++: as it is now in the README, it looks like one can compile the software on Ubuntu 14.04 by using clang >=3.4 and libc++. However this is not true, and your editor cannot be compiled with software available by default on Ubuntu 14.04. I hope the steps above can help other people which have this issue.
