The executable file of reef3d is not generated after following the ten videos, how to solve this problem?

Hei, could you provide a bit more context?
Did the make command fail? It usually provides an error message why it failed.

Entering the make -j 4 command brings up 'src/hypre_ ai j.h:30:9: fatal error:_hypre_utilities.h:No such file ordirectory

That looks like the installation of hypre failed (video 7). REEF3D's Makefile expects hypre to be located at /usr/local/hypre. If you installed hypre to another location you could move it to /usr/local or change the expected location in the Makefile of REEF3D.
