No, I get that undefined symbol error too but I thought it should be the fact that I compiled with different qt (madde, 4.6.3) than that on the device (4.7.4). However, as with the repos down it's impossible for now to set up a working thumb scratchbox target, I compiled it with desktop Qt for the simulator, and installed them in the simulator. However I'm getting the same error when importing. This new finding, and the fact that this happens to you too probably invalidates the above assumption. I'll try to find what causes that undefined symbol.
