I am experiencing problems with the gcc compiler. When I compiling a simple program it gives me the following error:

main.c:6:1: error: expected '=' , ',' , ';' , 'asm' or '__attribute__' before '{' token

{

^

main.c:9:1: error: expected '{" at end of input

}

^

 

I have the 3.4.112 kernel installed, when I compile and run the same program on my desktop it works, what can the problem be? Below is the code.

 

main.c

#include <stdio.h>

#include <stdlib.h>

#include "header.h"

int main(void){

    printf("%d", returnSeven());

    return 0;

}

 

source.c

int returnSeven(void){

    return 7;

}

 

header.h

int returnSeven(void);

 

not sure it can help https://en.wikipedia.org/wiki/Entry_point#C_and_C.2B.2B
