Introduction

If you're new to C++ and are trying to compile code that utilizes the ONNX Runtime API, you may run into a frustrating problem: the no such file or directory error. This typically occurs when the compiler cannot locate the specified header files, which can happen for a number of reasons.

In this guide, we'll delve into this common issue and provide a detailed, step-by-step guide on how to configure Visual Studio Code (VSCode) and your environment correctly to eliminate this error.

Understanding the Problem

You might have encountered a situation where you are trying to include a header file for ONNX Runtime in your C++ project, as shown below:

This error indicates that the compiler cannot find the specified header file onnxruntime_cxx_api.h. Let's explore how to troubleshoot this problem effectively.

Step-by-Step Solution

1. Locate the ONNX Runtime Header Files

First, ensure that you have correctly downloaded and installed the ONNX Runtime library. You should be able to locate the header files in your installation directory. For instance, if they are located in:

2. Verify Your VSCode Configuration

a. Update c_cpp_properties.json

The c_cpp_properties.json file is crucial for setting the include paths that VSCode will use. Open this file and make sure it includes the path to your ONNX Runtime header files. The configuration should look similar to this:

b. Update tasks.json

Next, you need to update the tasks.json file, which defines how the build process works. You must ensure that the include paths and library paths are correctly set. Here’s a sample configuration:

Make sure to incorporate both the include path and the library path specified above.

3. Compiling Your Code

After updating your configuration files, you should be able to compile your code without encountering the no such file or directory error. To do this, simply open the terminal in VSCode and run your build task by using the command palette or simply by pressing Ctrl + Shift + B.

4. Additional Debugging Steps

If the error persists:

Check that the paths in your configuration files are pointing to the correct locations where the ONNX Runtime files are installed.

Verify that the ONNX Runtime header files, along with any required .so files, are present in the specified directories.

Conclusion

By following the steps outlined in this guide, you should be able to resolve the no such file or directory error while working with the ONNX Runtime API in C++. This process involves validating your installation paths, correctly configuring your VSCode environment, and compiling your code efficiently.

If you continue to face issues, don't hesitate to revisit your configurations or seek help from communities such as Stack Overflow or GitHub where developers often share their solutions. Happy coding!
