This is outdated information, though the concepts are valid. A script implmenting these concepts for OpenConnect 8 on Ubuntu 18 (bionic) and 19 (eoan) is available

Building OpenConnect 7 on Ubuntu 14 (trusty) and 15 (vivid)

The steps in this guide are available as an autobuild shell script

Why?

#!/usr/bin/env bash
## NOTE! OpenConnect is now on Version 8, and this is only for historical use
##       See https://gist.github.com/darrenpmeyer/1a56d0d4817352998fe9d7cfe5a79684 for new script

oc_ver="7.08"

echo "Autobuild OpenConnect $oc_ver"
echo " "
echo "This script uses apt-get and make install via sudo rights"
echo "To simplify this, we're going to use sudo -v to pre-authenticate you"

REM - disconnecting from RDP usually locks the console. If you don't want that,
REM - such as when running a headless Steam game server, then use this to end
REM - your sessions instead.

REM - note that it can take up to 30s to disconnect this way, such is life.

This guide helps you build OpenConnect 7.x on OS X. You might want to do this if you want a newer version than the openconnect package in homebrew provides, or if you want to use libstoken support (for having an RSA soft token on your machine be used automatically by OpenConnect).

Shortcut

The version of OpenConnect on Homebrew has been updated, and so this whole guide can now be replaced with:

1. Install Homebrew from http://brew.sh and make sure it works
2. brew install openconnect --with-stoken
3. brew install stoken (See the "Using OpenConnect" section below for information about using stoken to set up soft tokens)

(NB: adapted from this Ask Ubuntu thread -- tested to work on Ubuntu 16.04 LTS through Ubuntu 22.04 LTS (Jammy).

Unlike using VMWare Tools to enable Linux guest capabilities, the open-vm-tools package doesn't auto-mount shared VMWare folders. This can be frustrating in various ways, but there's an easy fix.

TL;DR

Install open-vm-tools and run:

sudo mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other

# run $ ./getnet.sh [iface]
# 
# defaults to first non-local interface, but you can specify an interface.
# prints IP/Network in form 0.0.0.0/0 to STDOUT, so $(./getnet.sh en0) works
#
# e.g. run $ nmap -sP $(./getnet.sh en0)
# ^ will pingscan your current wifi network on macOS

-- yes, that is an oddly specific use case; I suspect most people will just use this for
-- reference to solve their own problems ;)

tell application "Microsoft Outlook"
	set currentEvents to selected objects
	--log currentEvents
	repeat with ev in currentEvents
		try
			set theSubject to the subject of ev
			--log theSubject

Applies to OS X 10.6 (Snow Leopard) and newer; tested through MacOS 10.13 (High Sierra)

The general advice for adding particular directories to your PATH environment variable on MacOS is to add an export PATH to your ~/.bashrc or equivalent. This has some drawbacks. For one, it only affects that shell for that user.

Additionally, sometimes installed Applications modify the system's default PATH in ways that you don't want.

Understanding how MacOS generates the PATH environment variable is instructive.

TL;DR read man path_helper and be enlightened
