fatal error in C - no such file or directory

Question

I am working through the CS50 course and downloaded the cs50.h file into the same directory as my cs50.c file.

However, I am receiving a fatal error cs50.h: No such file or directory when i include the cs50.h header in my program

#include <cs50.h>

Any suggestions, please? I'm using Code::Blocks 20.03

Cheers

Thanks, I've tried that. Irritatingly, I keep getting the same error message. I have no idea why though as the header file is in the same directory as the .c file... — john_joseph, Sep 14 '21 at 11:53

if it's not from an official lib you can't use <> you need to use "". But it's not a fatal error it doesn't really matter.
if it's in another directory you need to specify the path like so include "/file/anotherFile/cs50.h".
if it's your current directory you can write it like that it might fix the problem "./cs50.h"

hope it helped you !

what's your compiler – Tsirsuna Sep 14 '21 at 12:19

if you can try the gcc compiler it's more reliable – Tsirsuna Sep 16 '21 at 06:19
@john_joseph Code::Blocks is not a compiler, it's an IDE. – justANewb stands with Ukraine Jun 22 '22 at 00:32

Try running your file in the cs50 workspace. You would've set up a repository upon beginning the course.

for this I changed my compiler to clang and included cs50 as #include "cs50.h" instead of #include <cs50.h> and it worked fine. need to include all c files in the task, eg in vs code, tasks.json file should look like:

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: clang.exe build active file",
            "command": "C:\\mingw64\\bin\\clang.exe",
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${workspaceFolder}\\*.c",
                "-o",
                "${workspaceFolder}\\main.exe"
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "compiler: C:\\mingw64\\bin\\clang.exe"
        }
    ]
}

fatal error in C - no such file or directory
