How To Install GLIBC and GLIBCXX on Lubuntu 20.04 for Visual Studio Code

Ubuntu 15

In this article, we will guide you through the process of installing GLIBC and GLIBCXX on Lubuntu 20.04 for Visual Studio Code. These libraries are crucial for many applications, including Visual Studio Code, to function correctly.

Quick Answer

To install GLIBC and GLIBCXX on Lubuntu 20.04 for Visual Studio Code, you need to install the build-essential package using the command "sudo apt install build-essential". After installation, you can verify the versions of GLIBC and GLIBCXX using the commands "ldd –version" and "strings /usr/lib/x86_64-linux-gnu/ | grep GLIBCXX", respectively.


GLIBC is the GNU C Library that provides the system calls and basic functions of the C library, such as malloc, printf, and getpid. GLIBCXX, on the other hand, is a part of the libstdc++6 package, which is the GNU Standard C++ Library. This library includes everything from basic string handling to complex data structures.


Before we start, ensure you have administrative (sudo) privileges on your Lubuntu 20.04 system.

Step 1: Open a Terminal

Press Ctrl + Alt + T or search for “Terminal” in the application menu to open a terminal.

Step 2: Update the Package Lists

Before installing any new packages on your system, it’s a good practice to update the package lists. This ensures that you are downloading the latest version of the package. You can do this by running the following command:

sudo apt update

The sudo command is used to run the following command with superuser privileges. apt is the package handling utility in Ubuntu, and update is the command to refresh the package lists.

Step 3: Install the build-essential Package

The build-essential package includes a range of tools and libraries, including GLIBC and GLIBCXX. To install this package, run the following command:

sudo apt install build-essential

The install command is used to install a new package. build-essential is the name of the package we are installing.

Step 4: Verify the Installation

After the installation is complete, you can verify the versions of GLIBC and GLIBCXX by running the following commands:

To check the version of GLIBC, run:

ldd --version

The ldd command is a utility to print the shared libraries required by each program. The --version flag is used to display the version information.

To check the version of GLIBCXX, run:

strings /usr/lib/x86_64-linux-gnu/ | grep GLIBCXX

The strings command displays printable strings from files. /usr/lib/x86_64-linux-gnu/ is the file we are checking. The grep command is used to search for the term GLIBCXX in the output.


By following these steps, you should now have GLIBC and GLIBCXX installed on your Lubuntu 20.04 system, and you’re ready to install Visual Studio Code. If you already had the build-essential package installed, you should already meet the requirements for Visual Studio Code installation.

If you encounter any issues or errors during the installation, it’s recommended to seek further assistance or consult the official Lubuntu documentation.

Remember, the installation process may vary depending on your specific system configuration. Always ensure you have the latest updates for your system and packages to ensure a smooth installation process.

Can I install GLIBC and GLIBCXX on other Ubuntu-based distributions?

Yes, you can install GLIBC and GLIBCXX on other Ubuntu-based distributions by following similar steps. However, the package names or locations may vary slightly. It’s recommended to refer to the documentation specific to your distribution for accurate instructions.

Do I need to install GLIBC and GLIBCXX separately for Visual Studio Code?

No, GLIBC and GLIBCXX are included in the build-essential package, which is a prerequisite for Visual Studio Code installation. When you install build-essential, GLIBC and GLIBCXX will be installed automatically.

Can I use a different package manager instead of apt?

While apt is the default package manager for Ubuntu-based distributions, you can use other package managers like aptitude or Synaptic Package Manager. The package names and installation commands may differ slightly, so it’s important to consult the documentation for your specific package manager.

How can I update GLIBC and GLIBCXX to the latest version?

GLIBC and GLIBCXX are closely tied to the system and are usually updated through system updates. To update them, you can run the following command:

sudo apt update && sudo apt upgrade

This command will update all the packages on your system, including GLIBC and GLIBCXX, to the latest available versions.

Can I uninstall GLIBC and GLIBCXX?
