SDK/Setup/Debugging MeeGo Applications

In Qt Creator you setup MeeGo device configurations to deploy your application to either a real hardware device or to a virtual machine, such as QEMU, running on your host. Qt Creator treats these configurations in the same way. When you start to debug your application Qt Creator will package your applications as an RPM, deploy it to the device you've selected in your project settings, install it, and run the executable. The mad-developer package must be installed on the target OS.

Create a MeeGo Device Configuration

Open Tools > Options > Projects > MeeGo Device Configurations

Create a hardware device configuration: In the dialog box, create a new Device Configuration by clicking on Add. Give the new Device Configuration a name in the Configuration Name text field, and add the following settings in the other test fields: Device type: Remote device Authentication type: Password Host name: <IP Address of remote device> Ports, SSH: 6666 Note that the emulator is setup with a redirect from port 6666 on localhost to the SSH port (22) of the emulated device. Ports, Gdb Server: 13219 (the default) Note: If this port is not free, you can select another one. Connection Timeout: 30 User Name: root Password: meego Click Apply

Create a QEMU virtual machine device configuration: In the dialog box, create a new Device Configuration by clicking on Add. Give the new Device Configuration a name in the Configuration Name text field, and add the following settings in the other test fields: Device type: MeeGo emulator Authentication type: Password Host name: 127.0.0.1 Ports, SSH: 6666 Note that the emulator is setup with a redirect from port 6666 on localhost to the SSH port (22) of the emulated device. Ports, Gdb Server: 13219 (the default) Note: If this port is not free, you can select another one. Connection Timeout: 30s User Name: root Password: meego Click Apply

Test the settings
To test the settings, ensure that the emulated device is running, then click Test. If successful, you'll see a dialog box with the message "Device configuration successful". If the message "Could not connect to host" is displayed, check your setting selections and make sure that the network is connected.

Set Run Configuration

Click "Projects" on the left side. Select "Run" in the MeeGo Build/Run box at the top. Set the "Deploy to device" to the configuration created in the previous step.

Start the device (boot the hardware or virtual machine)

If you are debugging with a remote device, boot the device. If you are debugging with QEMU VM, start the virtual machine. You can do this from Qt Creator by clicking the "Start MeeGo Emulator" icon near the bottom left corner of the IDE.

(Optional) Set breakpoints in your code

It is easy to create breakpoints by clicking to the left of the line you wish to break on.

Start debugging the application

Click the "Run" or "Debug" icon to start your application. Qt Creator will package and deploy your application to QEMU or tablet device and start it on the target. Your application UI should appear on the remote device or virtual machine. The IDE will change to debug mode where you can view variables and software stack. You can view/step-through the code in the IDE while your application runs on the remote device or virtual machine.
