hello Eric, thanks for the response. I'd like to solve the Array issue first, then the boost because I have a feeling it is a different one because when I disable the relevant code it doesn't generates the error even when other parts of the program (such as the threadpool). here are the array files content: http://codepad.org/klDWMowB beside a strange typo that I've done, I don't thing I've miss configured it somehow.
