7 Example 5: Using a Shared or Static Library.6 Example 4: Building a Static Library (.a).5 Example 3: Building a Shared Library (.so).4 Example 2: A Project with Directories.How does make utility work internally? It creates a dependency graph of tasks and uses Topological Sorting algorithm to find a valid sequence that follows all of the given dependencies. Remember this should be done only after the makefile command is executedĮxamples: Output : hey there, welcome to geeksforgeeks

This is the syntax to run the makefile after typing this press enter the code will compile and that will create an executable file named “a” (in windows), “a.out”(in linux). Now all things we need is ready, the makefile code is complete now. The gcc compiler will compile the server.c file to get the server.o file The last thing we need is server.o file to get that file we need server.o object file and the server.h header file Now lets move to the third line here the client.o is needed(because this is used in first line of code)so the pre-requisites for that file are client.o and server.h file the gcc command will compile the client.c to get the client.o file. See the first line of the code in that “a” represents the object file which contains all the code that we wrote till now, after “a” there are two more object file they are client.o and server.o these are the object files which are required to make the object file “a”, in the next line there is gcc command remember this there should be 1 Tab space before writing the gcc command( if you forgot to put the tab this program will not run), the gcc command compiles the files given to it and stores in the name of its object files.

This is in windows so the object file is “a” if you are using the Linux, you replace “a” by “a.out”(without quotes)

Now read this carefully here i will show you how to write makefile, The third file which is server.h header file which calls the user defined functions in the server.c file and the fourth file which is makefile.mk which contains set of all the commands with their variable names. The client.c file contains the main function, the server.c file contains the user defined function, Make utility : This is a command line utility and used to process the instructions written in the Makefile. The main idea of this file is to specify the dependencies.

You can compile your project (program) any number of times by using Makefile. In a single make file we can create multiple targets to compile and to remove object, binary files. Makefile is a set of commands (similar to terminal commands) with variable names and targets to create object file and to remove them. Let us name the files as client.c and server.c and server.h and makefile.mk First we need to create 4 files in which 2 of them are. In this article, we are going to see how make utility can help us in making this simple.

There might be many dependencies in a project and manually following these dependencies and compiling files one by one becomes difficult. For example, there might be a file a.c that calls a function from b.c. When we build projects in C/C++, we have dependencies among files.
