C - Makefiles

In this project, I practiced writing Makefiles.

Tests ✔️

  • tests: Folder of test files. Provided by Holberton School.

Helper Files 🙌

  • holberton.c: C function that displays a seahorse in text. Used for Makefile practice purposes throughout project. Provided by Holberton School.

  • main.c: Main C function that runs the function defined in holberton.c. Provided by Holberton School.

Header File 📁

  • m.h: Header file defining the function prototype used in holberton.c. Provided by Holberton School.

Tasks 📃

  • 0. make -f 0-Makefile

    • 0-Makefile: Makefile that creates an executable holberton based on holberton.c and main.c. Includes:
      • Rule all that builds the executable.

  • 1. make -f 1-Makefile

    • 1-Makefile: Makefile that creates an executable holberton based on holberton.c and main.c. Builds on 0-Makefile with:
      • Variable CC that defines the compiler to be used.
      • Variable SRC that defines the .c files to compile.
      • The all rule only recompiles updated source files.

  • 2. make -f 2-Makefile

    • 2-Makefile: Makefile that creates an executable holberton based on holberton.c and main.c. Builds on 1-Makefile with:
      • Variable OBJ that defines the .o files to compile.
      • Variable NAME that defines the name of the executable.

  • 3. make -f 3-Makefile

    • 3-Makefile: Makefile that creates an executable holberton based on holberton.c and main.c. Builds on 2-Makefile with:
      • Rule clean that deletes all Emacs/Vim temporary files as well as the executable.
      • Rule oclean that deletes the object files.
      • Rule fclean that deltes all of the temporary files, executable, and object files.
      • Rule re that forces recompilation of all source files.
      • Variable RM that defines the command to delete files.

  • 4. A complete Makefile

    • 4-Makefile: Makefile that creates an executable holberton based on holberton.c and main.c. Builds on 3-Makefile with:
      • Variable CFLAGS that defines the compiler flags -Wall -Werror -Wextra -pedantic.

  • 5. Island Perimeter

    • 5-island_perimeter.py: Python function that returns the perimeter of an island defined in a grid.
    • Prototype: def island_perimeter(grid):
    • The parameter grid is a list of a list of integers.
      • Water is represented by 0.
      • Land is represented by 1.
      • Each element of the lists represents a cell square of side length 1.
      • Grid cells are connected horizontally/verticaly (not diagonally).
      • The grid is rectangular, with a width and height not exceeding 100.
      • The grid is completely surrounded by water, and there is either exactly one island or nothing.
      • The island does not contain lakes (water inside disconnected from surrounding land).

  • 6. make -f 100-Makefile

    • 100-Makefile: Makefile that creates an executable holberton based on holberton.c and main.c. Builds on 4-Makefile with:
      • Does not define the variable RM.
      • Never uses the string $(CFLAGS).
      • Does not compile if the header m.h is missing.
      • Works even if there are existing files of the same name as any of the Makefile rules in the current directory.
