Introduction

This is a guide to write a Qt program on one virtual PC, and deploy and debug it on another virtual PC. As a first step, both virtual PC's are running linux. this guide assumes a windows 7 host system, but this should work on each platform that can run Virtualbox.

Setting up the virtual machines

download needed files

Download Virtual box and VirtualBox Extension Pack from this site: http://dlc-cdn.sun.com/virtualbox/4.3.28/index.html This tutorial has been tested with virtualbox 4.3.28. Next download Ubuntu from this site: http://www.ubuntu.com/download/desktop This tutorial has been tested with 15.04 32bit.

Install Virtualbox

In windows, open VirtualBox-4.3.28-100309-Win.exe, and accept the defaults. Also accept the 4 prompts about device software installation. Then install Oracle_VM_VirtualBox_Extension_Pack-4.3.28-100309.vbox-extpack by double-clicking the file. Then click install, scroll down the PUEL, and click 'I agree'

Create the virtual machines, with a virtual network between them

Start Virtualbox, click file-preferences-general. Set the default Machine Folder to a spacious location. Next click machine-new, set the name to Ubuntu-master, type linux, version Ubuntu (32 bit), next Set memory size to 1024MB, next, create a virtual hard drive now, create, VDI, next, Dynamically allocated, next, select size: 50BG. Select Ubuntu master, then click Settings-storage-CD icon-choose a virtual CD/DVD file... Then browse to ubuntu-15.04-desktop-i386.iso, and click open. Select Network, Adapter2, enable adapter, attached to internal network, name "virtualLAN". click OK. Select Ubuntu-master, click machine-clone. New machine name: Ubuntu-target, next clone type=Full clone, clone

Master

This PC will be running the Qt IDE. This is where you will write the Qt program.

Target

This PC will be the target. This is where the Qt program will run. This PC has almost nothing installed, no IDE, no compilers, just a runtime
