Header.h: No such file or directory

I'm trying to link my c files and header files in compilation, but get the following error: fatal error: header1.h: No such file or directory #include <header1.h>

The problem is, I have included the header file using #include <header1.h> in each c file, and compiled using the command gcc header1.h file1.c file2.c main.c -Wall -std=c99 But still gives me the error in every c file. I've included the top of my code from each file below.

header1.h:

#include <stdio.h>
#include <stdlib.h>
#include <string.h> 

typedef struct microtreat{
    int id;                 
    char user[51];          
    char text[141];         
   
    struct microtreat*next;  
}treat;

main.c:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <header1.h>

file 1:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <header1.h>

file 2:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <header1.h>

How do I fix this error? Thanks

try

#include "header1.h"

when you use the <> include. the pre processor search's for the header in certain paths but if you want to include file in the directory of your c files you should use include ""

if you want to include header file in other directory you can compile it with the directory which the header is in like so:

gcc some_compilation_flags name_of_c_file_to_compile.c -iquote /path/to/the/header/directory

the flag -iquote say to the compiler to include this directory to find the include file in it

There are two ways of including headers in C/C++.
#include <header.h> looks for the header in the system path
#include "header.h" starts looking from the local folder of the file including the header

Here there is a much more detailed explanation
What is the difference between #include <filename> and #include "filename"?
