Build C++ code for Linux environment with Intel C++ compiler in Azure DevOps build pipeline

Question

I'm seeking advice on how to build C++ code for Linux environment with Intel C++ compiler in Azure DevOps build CI pipeline. It's a common practice if using gcc instead of Intel C++ compiler. But when it comes to Intel c++ compiler, any advice to have a license (either named user or floating) integrated into the build process?

Advice is appreciated!

For your scenario, it's recommended to use Self-hosted agent instead of Hosted agent .

Here's the list of preinstalled software in Microsoft-Ubuntu-hosted agent, we can find that it doesn't contain the Intel C++ compiler. So hosted agent doesn't have the environment to use Intel C++ compiler. Now you need to install linux self-agent in one of your local machines which has the Intel C++ compiler environment.

Note: Self-hosted agents give you more control to install dependent software needed for your builds and deployments.

Here're some steps for you:

Step 1: Download and install the Intel® Parallel Studio XE for Linux or Intel® System Studio for Linux . (Make sure you choose the correct edition and correct version)

Step 2: Download and install the Linux self-hosted agent.

Step 3: Choose your self-agent to run the pipeline. So your pipeline will execute in your local environment which has Intel C++ compiler.

Step 4: Use command-line tasks instead of normal build tasks in your pipeline like CMD task , bash task or Powershell task to invoke the compiler from the command-line. See Option 1: Use the Command Line :

• For C source files: icc helloworld.c
• For C++ source files: icpc helloworld.cc
