由于c++17，无法编译MK实时状态

Question

我想在this insturctions之后安装MK-Livestatus来连接nagios和thruk。

当我尝试使用./configure && make进行编译时，它会提示我：

checking whether g++ supports C++17 features with -h std=c++1z... no
configure: error: *** A compiler with support for C++17 language features is required.

我一直在寻找如何编译这段代码，但我从未找到有效的方法..

需要安装“gcc-7”或“gcc-8”。我通过构建仿生而不是Xenial解决了这个问题。要在Xenial上获取gcc-7，请运行以下命令：

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-7 g++-7
gcc-7 --version
# The following commands make gcc7/g++7 the defaults.
update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-7 60
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 60

这应该会让你克服你遇到的错误。
