C - Makefiles

In this project, I practiced writing Makefiles.

Tests ✔️

• tests: Folder of test files.

Helper Files 🙌

• school.c: C function that displays a seahorse in text. Used for Makefile practice purposes throughout project.

• main.c: Main C function that runs the function defined in school.c.

Header File 📁

• m.h: Header file defining the function prototype used in school.c.

Tasks 📃

• 0. make -f 0-Makefile

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

• 1. make -f 1-Makefile

  • 1-Makefile: Makefile that creates an executable school based on school.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 school based on school.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 school based on school.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 school based on school.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 school based on school.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.
