Include header file in different directory in c++

Question

I\'ve been learning c++ and encountered the following question: I have a directory structure like:

 - current directory

  - Makefile

  - include

     - he         


        

Answer 1

You told the Makefile that include/header.h must be present, and you told the C++ source file that it needs header.h … but you did not tell the compiler where such headers live (i.e. in the "include" directory).

Do this:

CFLAGS = -c -Wall -Iinclude
