Install Intel oneAPI DPC++/C++ Compiler on Ubuntu 24.04

Intel oneAPI DPC++/C++ Compiler is designed for C, C++, and Data Parallel C++ (DPC++) programming on Intel processor-based systems. It supports heterogeneous computing across CPUs, GPUs, and FPGAs, and is part of the Intel oneAPI initiative, which aims to deliver a unified programming model for diverse compute architectures. This tutorial explains how to install Intel oneAPI DPC++/C++ Compiler on Ubuntu.

Install Intel oneAPI DPC++/C++ Compiler

Download the oneAPI GPG key:

sudo wget -qO /etc/apt/trusted.gpg.d/intel-oneapi.asc https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB

Add the oneAPI repository:

echo "deb https://apt.repos.intel.com/oneapi all main" | sudo tee /etc/apt/sources.list.d/intel-oneapi.list

Update the package lists:

sudo apt update

Install the Intel oneAPI DPC++/C++ Compiler and related tools:

sudo apt install -y intel-oneapi-compiler-dpcpp-cpp

Create a startup script to automatically source Intel's environment setup on login:

echo 'source /opt/intel/oneapi/setvars.sh > /dev/null' | sudo tee -a /etc/profile.d/intel-oneapi.sh

To apply the changes immediately, either log out and log back in, or run the following command:

source /etc/profile

Verify the installation by checking versions:

icx --version

icpx --version

Testing Intel oneAPI DPC++/C++ Compiler

Create a main.c file:

nano main.c

Add the following code:

#include <stdio.h>

int main() {
    printf("Hello world\n");

    return 0;
}

Compile a code:

icx main.c -o test

Run the program:

./test

Uninstall Intel oneAPI DPC++/C++ Compiler

To fully uninstall the Intel oneAPI DPC++/C++ Compiler and all related dependencies, run the following command:

sudo apt purge --autoremove -y intel-oneapi-compiler-dpcpp-cpp

Delete the intel-oneapi.sh file, which was used for environment setup:

sudo rm -rf /etc/profile.d/intel-oneapi.sh

Remove GPG key and repository:

sudo rm -rf /etc/apt/trusted.gpg.d/intel-oneapi.asc

sudo rm -rf /etc/apt/sources.list.d/intel-oneapi.list
