How to Fix Header File Inclusion Errors in Visual Studio Code?

Understanding Header File Placement in Visual Studio Code for Error Resolution

Organising your codebase by separating header and source files into distinct directories can enhance clarity and maintainability. However, Visual Studio Code (VSCode) can encounter errors if header files are placed in a directory other than the source directory.

In your specific scenario, you have organised your files as follows:

- build
- include
 |- SDL2
 |- SDL2_Image
 |- someHeaderFile1.h
 |- someHeaderFile2.h
- src
 |- main.cpp
 |- someCppFile.cpp
- Makefile

When using #include directives to import these headers, VSCode displays errors because it expects them to be in the include folder's path relative to the source files. To resolve this, you need to add the include folder's path to VSCode's Include Path option.

Step 1: Open the Edit Configurations Window

• Press Ctrl Shift P to open the command palette.
• Search for and select "Edit Configurations."

Step 2: Add Include Path to Configuration

• In the Include Path field, paste the following path to your include directory:
  /path/to/your/project/include

Step 3: Close the Window and Compile

• After adding the path, close the configuration window.
• Recompile your code. The previous errors related to header file inclusion should now be resolved.
