I should also point out that no released SDK version includes functions for the multi-touch interface. @DmitryZ uploaded a newer version of the inkview.h header file, which includes descriptions of the multi-touch functions. It is impossible to link a program with those functions using the SDK's libinkview.so library file, though. I got around it in the pbimageviewer application by dynamically linking those functions only when the program is being run on a Touch device. You can get the source code for the application in the relevant thread and see how that's done, or take a look at this thread:
https://www.mobileread.com/forums/sho...d.php?t=197207. I think you could also try copying the libinkview.so file from your device and linking against that when building your application. The application would not work on the other non-Touch devices, but you probably don't care about that.
