features.h not found solus linux, what is it and how do I get it?

Question

In file included from /usr/include/c++/5.3.0/x86_64-solus-linux/bits/c++config.h:482:0,
             from /usr/include/c++/5.3.0/cstdlib:41,
             from prog1.h:4,
             from prog1.cc:1:
/usr/include/c++/5.3.0/x86_64-solus-linux/bits/os_defines.h:39:22: fatal error: features.h: No such file or directory
compilation terminated.

I'm fairly new to Linux/Unix and I'm trying just get basic c++ compiling on Solus (running on a virtual machine). I've installed gcc and g++ and as far as I can tell the standard c++ libraries are installed.

However, I am getting the error message shown above when I try to compile a program. This is my header file:

#ifndef PROG1_H
#define PROG1_H

#include<cstdlib>
#include<iostream>
#include<iomanip>
#include<vector>


const int VEC_SIZE = 250;
const int LOW = 1;
const int HIGH = 10000;
const int ITEMS_PER_LINE = 12;
const int ITEM_W = 5;
const int SEED = 1;

void genRndNums(vector<int>& v); // generates random integers and assigns them to the vector array

void printVec(const vector<int>& v); // prints the vector array, 12 numbers per line

#endif

for some reason the file features.h is missing and I don't know what it is or how to get it. If anybody can help with this I would really appreciate it.

Please install the system.devel component. Installing a compiler alone is not sufficient, you need headers and libraries too.

sudo eopkg it -c system.devel

Think of it as our equivalent to build-essential
