Are you using SDK 12 here as well, like in the other case you posted? app_trace is not part of SDK 12. Is this a clean project, or an old project you are trying to migrate from an older SDK version?

I ran into the same problem and was able to solve it by making sure the Thingy SDK location does not include any spaces in the containing directory names. For example, "~/Test_It/thingy_sdk" works using Eclipse but "~/Test It/thingy_sdk" does not an you get an error similar to yours.
