Yeah, looks as if I missed a line when I pasted line-by-line from my
history (without the command numbers). The last sed should have
been
sed -e '/core.h/ {
a #include <opencv2/imgproc/imgproc_c.h>
a #include <opencv2/imgproc/imgproc.hpp>
}' \
-i modules/video_filter/opencv_example.cpp
and I'm fairly sure that is what is in the book.

Moving to a new version of gcc is always interesting ;-)
