Include path not working for C debugger in VSCode - Raspberry Pi

Question

I am using VS Code remote via SSH to Raspberry Pi for my first C project. The code compiles without a problem, but the debugger can't find the header files. I have reviewed existing questions but the suggested solutions are not solving my problem.

If I place the header file in the root of my project, the file is found by the debugger.

Source, line 18:

#include "mfrc522.h"

The file is available in include folder:

tasks.json:

{
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: gcc build active file",
            "command": "/usr/bin/gcc",
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}",
                "--include-directory=${fileDirname}/**",
                "--include-directory=${fileDirname}/include/**",
                "--include-directory=${fileDirname}/src/*/*.c",
                "--include-directory=${fileDirname}/*.c"
            ],
            "options": {
                "cwd": "${fileDirname}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "Task generated by Debugger."
        }
    ],
    "version": "2.0.0"
}

c_cpp_properties.json

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/include/**",
                "${workspaceFolder}/**",
                "${workspaceFolder}/src",
                "${workspaceFolder}/src/*",
                "${workspaceFolder}/src/*/*.c"
            ],
            "browse": {
                "path": [
                    "${workspaceFolder}/include/**",
                    "${workspaceFolder}/**",
                    "${workspaceFolder}/src",
                    "${workspaceFolder}/src/*",
                    "${workspaceFolder}/src/*/*.c"
                ]
            },
            "defines": [],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "c17",
            "cppStandard": "gnu++14",
            "intelliSenseMode": "linux-gcc-arm64"
        }
    ],
    "version": 4
}

Resulting error:

main.c:18:10: fatal error: mfrc522.h: No such file or directory compilation terminated.

"the debugger can't find the header files" --- what do you mean exactly? What kind of error do you see? — n. m. could be an AI, Jun 29 '23 at 04:50
Why not SSH into the raspberry pi and invoke the debugger there? — t0mm13b, Jun 29 '23 at 06:25
@n.m.willseey'allonReddit thanks, I have added the exact error. — Superman.Lopez, Jun 30 '23 at 01:08
`"--include-directory=${fileDirname}/**",` and `"--include-directory=${fileDirname}/include/**"` are wrong for gcc. This documentation explains how to add an include directory: [https://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html](https://gcc.gnu.org/onlinedocs/gcc/Directory-Options.html) — drescherjm, Jun 30 '23 at 01:29
@drescherjm thanks, I'll read the linked document! I want to include all src and header files, even if in a deeper directory. At the moment I can point the debugger only at a specific directory and contained directories are ignored. — Superman.Lopez, Jun 30 '23 at 01:31

I had not seen this answer by bko earlier, which seems to have overcome the issue of including the header files.

What solved it for me was to just type folder path without /* or /** Then it prompted me if I want to enable Intellisense for this folder and I allowed it and it worked.
