Building for android: problems with Poco

Hi,

I am trying to build an openframeworks application for android and I am having multiple problems with Poco. This is the last error I have:

error: no matching function for call to 'std::unique_lock<std::mutex>::unique_lock(Poco::FastMutex&)'
         ofScopedLock lock(_mutex);

How could I fix this?
I also believe that there is something wrong with my poco linking because I've been having a lots of problems related to poco, what can I do to solve it?

Thanks
