I’ve recently installed the Tizen SDK for Wearables (Samsung Gear) onto Windows 7 64-bit, and overall, the install seemed to go OK. However, I’m unable to open a wearable emulator instance, and this has pretty well halted my development effort.

My emulator setup is basically the default for Gear (x86, 320×320, 316ppi, 512MB RAM), most of which I can’t seem to change anyway. I’ve tried all combinations of CPU virtualization and GPU on/off, with no difference in outcome.

And that outcome is: absolutely nothing happens. I can hear my CPU cooling fan kick on, and if I’m watching my Task Manager I can see a QEMU process spin for a few seconds, but nothing at all happens on-screen. The only other clue I have is in emulator.log, where I have the following error message:

Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.swt.widgets.Display
    at org.tizen.emulator.skin.EmulatorSkinMain.main(EmulatorSkinMain.java:318)

Anyone have any thoughts on this? I was rather hoping to port my app to Gear, but without an emulator, it’s DOA.
