However, when I included all the cpp files and built it, then came out this: fatal error C1083: “bool.h”: No such file or directory.
I do not know why this came out, as I checked all the steps in Dr. Mckenna's video and pdf file.

In my case it cannot find, 'tcl.h' file. Have you also encountered this error?
