Build and Run a Sample Project Using the Command Line

Intel® oneAPI Base Toolkit
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*. For details on how to use VS Code locally, see Basic Usage of Visual Studio Code with oneAPI on Linux*. To use VS Code remotely, see Remote Visual Studio Code Development with oneAPI on Linux*.
To compile and run a sample:
  1. Locate a sample project using the oneAPI CLI Samples Browser.
  2. Build and run a sample project using
    Make* or CMake*

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. You can find the samples browser in the
folder on your development host system.
An internet connection is required to download the samples for oneAPI toolkits. If you are using an offline system, download the samples from a system that is internet connected and transfer the sample files to your offline system. The samples can be downloaded from the code samples repository.
After you have downloaded the samples, follow the instructions in the
file. The readme file is located in the folder of the sample you are interested in.
To watch a video presentation of how to create a project with the command line, see Exploring Intel® oneAPI Samples from the Command Line.
Starting with Beta Update 8, the default installation directory has changed to
  1. Open a
  2. If you did not complete the steps in Option 2: One time set up for in the Configure Your System section,
    system variables by
    source /opt/intel/oneapi/
    The command above assumes you installed to the default folder. If you customized the installation folder,
    is in your custom folder.
    script can also be managed using a configuration file. For more details, see Using a Configuration File to Manage
  3. In the same
    window, run the application
    (it should be in your PATH)
    The oneAPI CLI menu appears:
  4. Use the up and down arrow keys to select
    Create a project
    , then press
  5. Select the language for your sample. For your first project, select
    , then press
    . The toolkit samples list appears.
  6. 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:
    To run a sample from the Intel® oneAPI DL Framework Developer Toolkit, see Build and Run an Intel® oneAPI DL Framework Developer Toolkit Sample Using the Command Line.
  7. After you select a sample, press
  8. Enter an absolute or a relative directory path to create your project. Provide a directory and project name. The Project Name is the name of the sample you chose in the previous step.
  9. Press
    to select Create, then press
    The directory path is printed below the Create button.

Build and Run a Project Using Make

  1. Open a command prompt.
  2. Navigate to the directory which you specified when creating (downloading) the project. If there is no makefile in the project, refer to the section below on how to use CMake to create a project with a makefile that you can use to run the design.
  3. Build the program using Make.
    cd vector-add && make all
  4. Run the program.
    make run
  5. Clean the program.
    make clean

Build and Run a Project Based on a oneAPI Sample using CMake

To run a different sample using CMake, where
is the name of the sample you want to run.
  1. If necessary, re-run the command-line utility and select a CMake project that contains a
    cd <sample_name>
  2. Navigate to the build directory.
    mkdir build cd build
  3. Build the program. Run CMake in the build directory to create the makefile. Use the newly created makefile to build the executable.
    cmake ../. make VERBOSE=1
  4. Run the program.
    make run
  5. Clean the program.
    make clean

Compile and run a sample for FPGA

You can run the
sample (or any FPGA Data Parallel C++ (DPC++) 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
    . This can be used with the
    Intel® oneAPI Base Toolkit
    . For more information about the reports, refer to the Intel
    oneAPI DPC++ FPGA Optimization Guide
  • Hardware:
    Generates the actual bitstream on an FPGA device. Compilation can take few hours to complete. Use this mode to measure performance. Download the Intel
    FPGA Add-On for oneAPI Base Toolkit
    to use this mode.
After downloading the vector-add design example using the oneAPI CLI Samples Browser, perform the following steps to compile and run the design:
  1. Change to the directory containing the
    design example using:
    cd <vector-add directory on the same system>
  2. Run the following
    make clean
    command before you start compiling.
    make clean -f Makefile.fpga
  3. Compile the design using one of the following options:
    • Compile for emulation using:
      make fpga_emu -f Makefile.fpga
    • Compile the report using:
      make report -f Makefile.fpga
      You can view the report at
      . This does not generate an executable.
    • Compile for hardware (takes a longer duration to complete) using:
      make hw -f Makefile.fpga
    If you compiled the hardware on a development system, copy the executable file
    to the runtime system.
  4. Run the design using one of the following options:
    • Run the design for emulation using:
      make run_emu -f Makefile.fpga
      If you are using a separate development system, perform this step on that system.
    • Run the design on FPGA hardware using:
      make run_hw -f Makefile.fpga
    To understand the command used in the Makefile, refer to the Intel® oneAPI Programming Guide.
