```
configure: No compiler with C++11 support was found
configure: error: Either upgrade your compiler, or use ZNC 1.4
```
Recommending 1.4 is not a good idea as it's old and unsupported version, doesn't check SSL certificates (https://github.com/znc/znc/issues/156) and is vulnerable (https://github.com/znc/znc/issues/621) to [POODLE](https://en.wikipedia.org/wiki/POODLE) and [FREAK](https://en.wikipedia.org/wiki/FREAK).

2015-04-17 12:06:11+0300 < Mikaela> gcc isn't the only compiler, I use clang by default

I have no idea on other compilers, but as far as I am aware, gcc and clang are the most popular ones.
> Clang 3.3 and later implement all of the ISO C++ 2011 standard.
