How to use the make command in Linux ?

The make command is a powerful tool used to build and manage programs from source code on a Linux system. It is a fundamental building block of the Linux operating system, and is used to compile, link, and build programs from source code. 

Here at Fixwebnode, we shall look into how make command works.

 

What is the Make Command?

The make command is a program designed to automate the building of complex software projects. It reads instructions from a text file called a makefile, which contains instructions on how to build the project. The make command can be used to compile and link source code files, create object files, and build executable files.

 

How to Use the Make Command ?

Using the make command is simple. To use it, you first need to create a makefile, which contains instructions on how to build the project. Once the makefile has been created, you can then use the make command to build the project.

To use the make command, open a terminal window and type in the following command:

$ make -f [makefile_name]

where [makefile_name] is the name of the makefile. 

This will execute the instructions in the makefile and build the project.

 

Example of using Make Command

Let's look at an example of how to use the make command. 

Suppose we have a C program called hello.c, which contains the following code:

#include <stdio.h>
int main() {
printf("Hello World!
");
return 0;
}

To compile and link this program, we need to create a makefile, which contains instructions on how to build the project. The makefile should look like this:

hello: hello.c
gcc -o hello hello.c

This makefile contains instructions on how to build the hello program. It tells the make command to use the GNU C Compiler (gcc) to compile and link the hello.c source file and create an executable file called hello.

 

Now that we have created the makefile, we can use the make command to build the project. To do this, open a terminal window and type in the following command:

$ make -f hello

This will execute the instructions in the makefile and build the hello program. Once it is finished, you should have an executable file called hello in the current directory.

CONCLUSION

The make command is a powerful tool used to build and manage programs from source code on a Linux system. It is a fundamental building block of the Linux operating system, and is used to compile, link, and build programs from source code. This tutorial has provided an overview of the make command and explained how to use it through practical examples.

 

How to fix the "make command not found" error in Linux ?

If you're trying to use the make command in Linux, but you're receiving the error "make command not found," you're not alone! This is a common problem that can be easily fixed. Here's a tutorial on how to fix it. 

 

1. Check if make is installed

The first step is to check if make is actually installed on your system. You can do this with the command:

$ sudo apt-get install make 

This command will check to see if make is installed on your system and install it if it's not already. 

 

2. Check if make is installed correctly

If make is already installed, it may not be installed correctly. You can check this with the command:

$ which make 

This command will list the path of the make command, if it is installed correctly. 

 

3. Reinstall make

If the command is not found or is not installed correctly, you can reinstall make using the command:

$ sudo apt-get --reinstall install make 

This will reinstall make, ensuring that it is installed correctly. 

 

4. Check if make is in the PATH

Lastly, you should check if make is in the PATH. This is a variable that contains a list of directories where programs are located. To check if make is in the PATH, run the command:

$ echo $PATH

If make is not in the list, you can add it with the command:

$ export PATH=$PATH:/usr/bin/make

This will add the path for make to the PATH variable. 

 

That's it! You should now be able to use the make command without any errors.
