Building OpenSSL 1.1.0 with Microsoft VS 2015

MCCI needs OpenSSL for a Windows project (that will be cross-platform). A casual search didn't turn up either a good source for cross-platform libraries, which meant we have to build them ourselves. A deeper search found a detailed guide here, and yet the details don't match what I found when I checked out the code; and the post doesn't talk about doing it directly from GitHub (which I wanted to do).

Here's the procedure for building OpenSSL on 64-bit Windows 10, with Visual Studio 2015.

If you don't have it, please install git bash from git-scm.com.
Start a git bash window.

In the following, I'll use lines beginning with {dir} $ to designate input to a bash Window. We'll also have to use a cmd.exe Window for much of the build, and those lines will be marked {dir}>, just as on Windows..

	1027. 打印沙漏(20)

	本题要求你写个程序把给定的符号打印成沙漏的形状。例如给定17个“*”，要求按下列格式打印

	*****
	***
	*

	*****

	ln -sf /usr/share/zoneinfo/$(tzselect) /etc/localtime
	hwclock --systohc

	nano /etc/locale.gen && locale-gen
	read -p "Default LANG is? [en_US,zh_CN...]" loc
	echo "LANG=$loc.UTF-8" >> /etc/locale.conf

	read -p "Hostname is?" hn
	echo $hc > /etc/hostname
	echo "127.0.1.1\t$hc.localdomain\t$hc" > /etc/hosts

	#!/bin/bash

	#check network connection
	con=$(ping -q -w 1 -c 1 `ip r \| grep default \| cut -d ' ' -f 3` > /dev/null && echo ok \|\| echo error)
	if [ $con == "error" ]; then
	exit -1
	fi

	timedatectl set-ntp true
	lsblk

	create initial layout, this write settings to --layout dir

	D:\>vs_community.exe --layout D:\vs2017layout --lang en-US --add Microsoft.VisualStudio.Workload.NetWeb --add Microsoft.VisualStudio.Workload.ManagedDesktop --add Microsoft.VisualStudio.Workload.NativeDesktop --add Microsoft.VisualStudio.Component.CoreEditor --add Microsoft.VisualStudio.Component.NuGet --add Microsoft.VisualStudio.Component.VC.Tools.x86.x64 --add Microsoft.VisualStudio.Component.Windows10SDK.16299.Desktop --add Microsoft.VisualStudio.Component.Windows81SDK --add Microsoft.Component.VC.Runtime.UCRTSDK

	after initial layout creation, just execute this to update layout

	D:\>D:\vs2017layout\vs_community.exe --layout D:\vs2017layout

	clean old layout, after this cmd, can delete the Archive dir
