Overview

The virtualised SDK architecture supports multiple devices and emulators with a single Build Engine.

The main components are:

• Build Engine
• Qt Creator
• Virtualbox Emulator(s)
• Physical device(s)

Shared Folders

Shared folders are used for sharing:

• Configuration
• SSH keys
• Home directory
• Targets
• Other source directory trees

There are 3 shared folders.

mersdk:/etc/mersdk is mapped to the SailfishOS application areas mersdk folder and contains: configuration, targets and the ssh keys

home:/home/mersdk is mapped to the users 'home' directory

srcN:/home/srcN are each mapped to source directory areas on the host

Networking

Overview

The SDK network serves the following purposes:

• Host -> Build Engine for ssh/web
• Host -> Emulator for ssh/debugging
• Host -> Device for ssh/debugging
• Build Engine -> internet for updates and information
• Build Engine -> Device with ssh to support deployment
• Emulator -> internet for updates and information
• Build Engine -> Emulator with ssh to support deployment

To do this the Emulator and Build Engine will have 2 network adaptors. An adaptor running in NAT mode allows open outbound access and permits some incoming connections (ssh, www and gdb). This also handles Engine > Device connectivity. Another adaptor is a VirtualBox internal adaptor and supports open Build Engine <> Emulator(s) connectivity.

QtCreator and the Build Engine need to collaborate to setup the Emulator internal networking.
