How to Solve the Path to IAR SDK Not Found Error When Using Headless Builds in Eclipse CDT

When working with embedded C projects, leveraging the Eclipse IDE for headless builds can streamline the development and deployment processes. However, developers may run into issues such as the confusing error message indicating that the "Path to IAR SDK not found." This guide walks you through a comprehensive solution, starting from updating configurations in Eclipse to optimizing command line executions.

Understanding the Problem

Imagine you have a project built with Renesas e2studio for the Synergy platform, but you're attempting to compile it using IAR Embedded Workbench through Eclipse CDT's headless build feature from the command line. You try to execute a command designed to build your project, but it fails with an error pointing to the SDK path not being found for the IAR provider. This can halt your development process and leave you searching for answers.

Typical Error Message

You might encounter an error similar to this:

This problem usually indicates that Eclipse cannot locate your IAR SDK installation.

Step-by-Step Solution

Here’s how to resolve this error and allow Eclipse to find the IAR SDK automatically when building from the command line.

Step 1: Update Preferences in Eclipse

Open e2studio: Launch your Renesas e2studio application.

Access Preferences: Navigate to the IAR SDK plugin preferences. Look for a section where you can specify the path to the IAR installation directory.

Set IAR Path: Ensure that the path you specify correctly points to the IAR Embedded Workbench installation on your system.

Step 2: Export Your Preferences

After updating your settings:

Export Preferences: In the same preferences window, find the option at the bottom left to export preferences. Click it.

Apply and Continue: You should see a prompt to "Apply and Continue." Make sure to agree to this so that your updated settings are saved properly.

Step 3: Locate Your Preferences File

Open Your Preferences File: Look for the exported file, typically named MyPrefs.epf, and open it with a text editor.

Search for IAR Entries: Conduct a search within this file for the term "iar". You’ll want to identify lines similar to:

Step 4: Update the Plugin Customization File

Copy Relevant Lines: Copy the necessary contents of the IAR path configuration you found in the previous step, excluding the /instance/ prefix.

Navigate to the Customization File: Locate the plugin_customization.ini file generally found in the C:\Renesas\Synergy\e2studio...\eclipse\plugins directory.

Paste Changes: At the end of the plugin_customization.ini file, paste the lines you copied earlier. Be careful with formatting to ensure compatibility.

Finalizing Your Setup

With the configuration complete, e2studio should now be able to locate the IAR SDK automatically during headless builds. This removes the need for further manual adjustments when operating via the command line.

Optional Optimization Tip

To enhance the build process further:

You can invoke the --no-indexer option in your command to speed things up as you build your project. Here’s an example command with the optimization:
