537make

A build tool to read, validate and execute make files. Uses fork and execvp for creation of new processes and command execution.

Task List

This project is divided in the following major modules.

• Input Parser:

  • Reads the command line arguments if passed and parses them.
  • Reads the make file and parses to create a graph structure for all the targets which are to be executed.

• Target Executor:

  • Traverses through the graph (assuming no cycles) in PostOrder manner.
  • Checks if a target requires rebuilt as per the modification time of all its dependencies.
  • Executes all the commands associated with a target if target building is required.

• Entities:

  • Graph:

    • It defines all the target node in the makeFile. All the dependencies and command associates are part of this structure.
    • It also provides following functionality.
    • This also lets you create all the connections among graph Node.
    • It also has cycle detection method

  • linkedList:

    • It defines the list of dependencies associated with TargetNode.
    • All the commands node are also modeled as linkedList

  • struct_input:

    • This input structure stores the input commands like target or makefile provided in the command line.

• Utils:

  • Constants used across the program.
  • Validator used across the program.

• driver.c is the driver module for the entire project.
