Installation does not succeed on Ubuntu 16.04 about mmpp HOT 4 CLOSED

As a matter of fact, it turned out that it was not too difficult to port the codebase to C++14, so now GCC 5 works as well. I though I used more of C++17 features, but apparently they are all actual C++14 features. So thanks for insisting! I have updated mmpp.po and the readme to reflect the new situation.

So, for the moment I consider C++14 the official standard for the codebase. Fortunately Ubuntu should soon ship a new LTS release with GCC 7 in it, so if there is a need for some C++17 feature I will not have to wait too much.

I usually use GCC 7 to build mmpp. I just pushed a little change to allow GCC 6, but I believe that GCC 5 is just too old in terms of supporting C++17 and it would require a lot of changes that I would like to avoid. So unfortunately I think that you need to either install a more recent GCC from the PPA, or install a little virtual machine to test mmpp, or just wait until it is safe to upgrade to 18.04.

I will write about this in the README.

Sounds good. As long as the installation instructions mention it, requiring GCC 6 is fine.

Not working on the compiler for the current long term support version seems a little strong. What functionality is it that you're really depending on?
