Building for android: problems with Poco

Thanks for your answer Arturo.

This particular error is in the line 372 of the file ofxHTTP/libs/ofxHTTP/src/WebSocketConnection.cpp , which is the first line in this function:

std::size_t WebSocketConnection::getTotalBytesSent() const
{
    ofScopedLock lock(_mutex);
    return _totalBytesSent;
}

I have not written this function, as is part of ofxHTTP, so I am not sure if I should change it or not.
