Intel® oneAPI Base Toolkit
Note
If you have not already configured your development environment, go to
Configure Your System then return to this page. If you have already completed the steps to configure your system, continue with the steps below.
Command line development can be done with a terminal window or done through Visual Studio Code*. Some tasks can be automated using extensions. To learn more, see
Using Visual Studio Code with Intel® oneAPI Toolkits.
To compile and run a sample:
- Locate a sample project using the oneAPI CLI Samples Browser.
- Build and run a sample project using
Microsoft Build*.
Download Samples using the oneAPI CLI Samples Browser
Use the oneAPI CLI Samples Browser to browse the collection of online oneAPI samples. As you browse the oneAPI samples, you can copy them to your local disk as buildable sample projects. Most oneAPI sample projects are built using Make or CMake, so the build instructions are included as part of the sample in a README file. The oneAPI CLI utility is a single-file, stand-alone executable that has no dependencies on dynamic runtime libraries.
To see a list of components that support CMake, see
Use CMake to with oneAPI Applications .
An internet connection is required to download the samples for oneAPI toolkits. For information on how to use this toolkit offline, see
Developing with Offline Systems in the
Troubleshooting section.
To watch a video presentation of how to create a project with the command line, see
Exploring Intel® oneAPI Samples from the Command Line.
Note
The oneAPI CLI Samples Browser does not work with system proxy settings and does not support WPAD proxy. If you have trouble connecting from behind a proxy, please see
Troubleshooting.
- Create a folder where you want to store your sample. For example,
C:\samples\vector-add
- Open a
command
window.
- Set system variables by
running setvars:
"C:\Program Files (x86)\Intel\oneAPI\setvars.bat"
Note
For Windows PowerShell* users, execute this command:
cmd.exe "/K" '"C:\Program Files (x86)\Intel\oneAPI\setvars.bat" && powershell'
The command above assumes you installed to the default folder. If you customized the installation folder,
setvars.bat is in your custom folder.
- In the same
command
window, run the application
:
oneapi-cli.exe
The oneAPI CLI menu appears:

- Use the up and down arrow keys to select
Create a project, then press
Enter
- Move the arrow key down to select
Create a project, then press
Enter. The language selection will appear. If you want to run samples from a toolkit other than the
Intel® oneAPI Base Toolkit, install the domain-specific toolkit before proceeding.

- Select the language for your sample. For your first project, select
cpp, then press
Enter. The toolkit samples list appears.
- Select the
Vector Add sample. Vector Add is a simple test application that will help verify that the tools are setup correctly and can access your system's GPU:

After you select a sample, press
Enter.
- Specify the location for the project. The default location includes the path from where the utility was run and the name of the project.
Press
Tab to select Create, then press
Enter:

Build and Run a CPU or GPU Sample Using Microsoft Build*
- Using the same command prompt window where you ran
setvars.bat, navigate to the folder where you downloaded the sample.
- Configure the project to use the buffer-based implementation (first box) or the Unified Shared Memory (USM) based implementation (second box):
mkdir build
cd build
cmake -G "NMake Makefiles" ..
mkdir build
cd build
cmake -G "NMake Makefiles" .. -DUSM=1
- Build the program.
nmake cpu-gpu
- Clean the program.
nmake clean
- Navigate to the output directory (example:
x64/Release)
- Run the program:
vector-add-usm.exe
vector-add-buffers.exe
A
success message will appear:

If
Running on Device shows a GPU and an error occurs, see the Troubleshooting tip for fixing a
SPIRV Error.
Compile and run a sample for FPGA
You can run the
vector-add sample (or any FPGA SYCL* code) in the following modes:
- Emulation: Verifies the code correctness. Compilation completes in few seconds. Use this mode if you are using the
Intel® oneAPI Base Toolkit
- Report: Generates a static optimization report for design analysis. Compilation can take a few minutes to complete. When completed, you can find the reports in
<project_name>.prj\reports\report.html. This can be used with the
Intel® oneAPI Base Toolkit. For more information about the reports, refer to the
FPGA Optimization Guide for Intel® oneAPI Toolkits.
- Hardware:
Generates the actual bitstream on an FPGA device. Compilation can take few hours to complete. Use this mode to measure performance. To use this mode, download the Intel® Quartus® Prime Pro Edition software and third-party vendor-provided BSPs separately. For more information, refer to the
Intel® FPGA Add-On for oneAPI Base Toolkit web page.
- Using the same command prompt window where you ran
setvars.bat, navigate to the folder where you downloaded the sample.
cd <vector-add directory on the same system>
- View the
README.md file in the sample folder for instructions on how to build and run the sample.
