Install build essential tools on Ubuntu 22.04 or 20.04 LTS Linux

To compile programs from their source code, we need some tools and libraries available through a single package called on Build essential on Ubuntu 20.04 | 22.04 |18.04 or Debian 11 | 10 base repository. Here we learn how to install it.

Build essential is a name for a package that includes the GCC/g++ compilers and libraries and some other utilities required to compile software written in C and C++.

The Gnu Compiler Collection, GCC for short, is a collection of compilers and offers a uniform interface for creating programs in C, C ++, Objective-C, Fortran, Ada, Assembler and Go.

The original meaning of GCC was GNU C Compiler, but because several other languages ​​have been added since then, the meaning has changed to GNU Compiler Collection. Today the C compiler is called gcc in lower case to make it possible to distinguish it from the whole.

The key packages automatically installed on our Debian or Ubuntu system from Build-essentials are GCC– it is a GNU compile for C Programming; g++ for compiling C++ programming language; libc6-dev – GNU C library; Make – The traditional build system or a tool directs compiler how to work; to pack or unpack a Debian package, utility dpkg-dev is also there.

In short, by setting up build-essential we get all the required tools we need to compile software on Ubuntu/Debian systems.

What is Build Essential Package in Ubuntu? How to Install it?

Brief: This is a quick tip to inform new Ubuntu users about the build-essential package, its usefulness and the installation steps.

Installing build-essential package in Ubuntu is as simple as typing this command in the terminal:

But there are several questions around it that you may want answers to:

• What is build essential package?
• What does it contain?
• Why should you install it (if install at all)?
• How to install it?
• How to remove it?

What is build-essential package in Ubuntu?

The build-essential package actually belongs to Debian. It is not a piece of software in itself. It contains a list of packages that are required to create a Debian package (deb). These packages are libc, gcc, g++, make, dpkg-dev etc. The build-essential package contains those required packages as dependencies, so when you install build-essential, you install all those packages in one single command.

Please do NOT consider build-essential to be a super package that will magically install all kind of development tools from Ruby to Go for you in a single command. It has some development tool but not all.

Why would you want to install build-essential package?

It is used for creating DEB packages from the source code of an application. An average user does not go around creating DEB packages everyday, right?

However, some users may use their Ubuntu Linux system for software development. You want to run c program in Ubuntu, you need gcc compiler. You want to run C++ programs in Ubuntu, you need g++ compiler. If you have to use an unusual software that is only available from the source code, your system will throw make command not found error because you need to install make tool first.

All this can be installed individually, of course. However, it is much easier to take advantage of the build-essential package and install all these development tools at once. That’s the benefit you get.

Now that you know the advantage of this package, let’s see how to install it.

Installing build-essential package in Ubuntu Linux

Open a terminal in Ubuntu by pressing the Ctrl+Alt+T shortcut and enter the following command:

With sudo command, you’ll be asked to enter your account’s password. When you type it, nothing is displayed on the screen. That is fine. That’s how it works in most Linux systems. Type your password blindly and press enter.

The apt update command refreshes the local package cache. This is essential for a fresh Ubuntu install.

After that, run the following command to install build-essential tool:

It should show all the packages it is going to install. Press Y when asked for confirmation:

Wait a bit for the installation to complete. That’s it.

Removing build-essential tool from Ubuntu

Keeping those development tools won’t harm your system. but if you are running low on the disk space, you may consider removing it.

Removing software is easy in Ubuntu thanks to the apt remove command:

It will be a good idea to run the autoremove command to remove the residual dependency packages as well:

How to install build-essential? [duplicate]

I am trying to install G++ compiler in Ubuntu 13.10. It told me I needed to install the build-essential package.

I have tried the below code

It gives me this error:

Type in the Terminal sudo apt-get install build-essential and then press key TAB instead of pressing ENTER .

Enable main repository in Software & Updates.

Then run these commands in a terminal:

You have to enable the main repository in the /etc/apt/sources.list file.
To accomplish this remove the ‘#’ character in front of the following lines.

Save the file and execute
sudo apt-get update && sudo apt-get install build-essential .

Well, sometimes what happens is that if your first command fails due to some repo not responding or other network issues

Then you may not be able to install build-essential. So always ensure that apt-get update completes successfully. Once update is commpleted, issue:

Now you should be able to install it successfully.

You can also install build essentials from software center
Open it up, and search for «build essential»

These terminal commands should solve your problem:

First remove the Merge List by opening a terminal (Press Ctrl+Alt+T to launch) and run this command:

these command lines are interchangable

the options used are -v verbose

If you are ever unsure about a command line or the options being used always refer to the manual page for the command. These can be accessed on the internet by searching for man and the command for example man rm or you can access the same information by typing exactly the same command in the terminal for example man rm instructions for quitting the page will be at the bottom of the terminal like this

picture of man page options

Next, generate a new one by running a simple update:
