first code won't run

[Brian Beuken]

Oh and for future reference, the VS error list is sometimes too concise and does not give a lot of info on the errors, much better to switch your tab view to the output, which would give a more easy to follow error (well easy for some )

here I was able to read a more complex error and noticed that pthread was at fault. The errors don't always make sense but they give more information that can lead to the cause.
