First application

if you don't have the SDK installed and running yet, follow the "installation guide.":/wiki/SailfishOS_SDK_Installation

1.Launch Sailfish OS IDE

You can launch from the 'SailfishOS IDE' entry in the system menu (or from ~/SailfishOS/bin/qtcreator if you're a linux terminal person).

As an example, on Ubuntu, open the dash, type in 'sailfish'. Click on the 'SailfishOS IDE' icon to launch the IDE.

2. Create a Sailfish UI project

The SDK comes with a Sailfish UI template project that makes it very easy to get started. Dialog windows shown in screenshots may vary between diffrent versions/systems so treat them as a example.

1. In the IDE, click on File→New File or Project
2. Select Applications→SailfishOS Qt Quick Application.

What's the diffrence? Generally MerSDK-SailfishOS-i486-x86 kit is used when deploying your application on emulator, the second kit is used when deploying application on Mer ARM device. Select kit screenshot

1. You can edit the short description of your project or just click Next

3. Launch the Mer build machine and Emulator

The SailfishOS SDK uses a Mer build machine to compile your code and another virtual machine to run an emulator. If these are not running when you attempt to build or deploy an application you will be asked to start them.

Note: The Mer build machine needs access to your source code to compile it and by default your home directory is shared - this is why the project should be in your home.

When a Sailfish OS project is open, the SDK automatically displays two control buttons in the left toolbar for starting/stopping the Mer build machine and Emulator. Mer build toolbar screenshot

3.1. Click on the launch Mer Build Engine icon screenshot icon to launch Mer Build Engine.

The Mer Build Engine is started in the background and the icon will turn gray until the machine has booted up.

3.2.— Click on the launch the emulator icon screenshot icon to launch the emulator.

A new VirtualBox window opens and boots up the emulator. working emulator screenshot

4. Successful connection

When the QtCreator can successfully connect to both the emulator and Mer build machine, the icons are updated as shown below.

Connection established: Connection established screenshot

5. Build and Deploy the app

Press the play/run button screenshot play/run button in the toolbar to compile and run the project on the emulator.
