How To Install Clang on Ubuntu 24.04 LTS
In this tutorial, we will show you how to install Clang on Ubuntu 24.04 LTS. Clang is an open-source compiler front-end for the LLVM compiler infrastructure project. Known for its fast compile times, helpful error messages, and excellent support for C++, Clang has gained popularity among developers worldwide. As part of the LLVM project, Clang offers a modern source- and target-independent optimizer, along with code generation support for many popular CPU architectures.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Clang on Ubuntu 24.04 (Noble Numbat). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.
Prerequisites
- A server running one of the following operating systems: Ubuntu and any other Debian-based distribution like Linux Mint.
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- Basic familiarity with the terminal and command-line interface.
- SSH access to the server (or just open Terminal if you’re on a desktop).
- An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies.
- An Ubuntu 24.04 system with root access or a user with sudo privileges.
Install Clang on Ubuntu 24.04
Step 1. Updating the Package Repository.
Before installing any new software, it’s crucial to ensure that your system is up-to-date. This step helps prevent potential conflicts and ensures that you have the latest security patches and bug fixes. Open a terminal window and run the following commands:
sudo apt update sudo apt upgrade
The first command updates the package lists, while the second upgrades all installed packages to their latest versions. If prompted, enter your password and confirm any necessary actions.
Step 2. Installing Clang.
- Installing Clang Using APT Package Manager
The simplest and most straightforward method to install Clang on Ubuntu 24.04 LTS is by using the Advanced Package Tool (APT), Ubuntu’s default package management system. Run the following command to install Clang:
sudo apt install clang
Once the installation is complete, verify the installation by checking the Clang version:
clang --version
This command should display the installed version of Clang, confirming a successful installation.
If you need a specific version of Clang, you can search for available versions using the following command:
apt search clang
To install a particular version, use the following syntax:
sudo apt install clang-<version>
Replace <version> with the desired version number. For example, to install Clang 15, you would use:
sudo apt install clang-15
- Using LLVM Repository Script to Install Clang
For those who require the latest versions of Clang or need more control over the installation process, the LLVM project provides a convenient script to install Clang and related tools. Download the LLVM installation script:
wget https://apt.llvm.org/llvm.sh
Make the script executable:
chmod +x llvm.sh
Run the script with sudo privileges, specifying the desired version:
sudo ./llvm.sh <version>
Replace <version> with the version number you want to install. For example, to install the latest version, you can use:
After the installation is complete, verify the installation by checking the Clang version:
clang --version
Step 3. Compile a simple C program to test Clang.
Create a file named hello.c with the following content:
#include
int main() {
printf("Hello idroot.us, Clang on Ubuntu 24.04 LTS!\n");
return 0;
}
Compile the program using Clang:
clang hello.c -o hello
Run the compiled program:
./hello
If everything is set up correctly, you should see the output:
Hello idroot.us, Clang on Ubuntu 24.04 LTS!
Step 4. Installing Additional LLVM Tools.
Clang is part of the larger LLVM project, which includes various tools for code analysis, optimization, and debugging. To install additional LLVM tools, you can use the following command:
sudo apt install llvm
This command will install the LLVM toolchain, including tools like llvm-ar, llvm-nm, and llvm-objdump.
Congratulations! You have successfully installed Clang. Thanks for using this tutorial for installing Clang on the Ubuntu 24.04 LTS system. For additional help or useful information, we recommend you check the official Clang website.
