I need help to run sample code from internet

I am trying to run sample code on my PC

I have following three files taskrunner.h task.h runtask.c

Code:

---

#ifndef TASKRUNNER_H#define TASKRUNNER_H
int taskrunner(Task * TaskList, unsigned int listLen);


#endif        // TASKRUNNER_H

---

Code:

---

#ifndef TASK_H#define TASK_H


typedef int (*task_init)(int);
typedef int (*task_func)(int);


typedef struct {
        char taskName[20];
        // task_init init;
        // task_func func;
        int *        runNow;
} Task;


#endif        //TASK_H

---

Code:

---

#include "stdio.h"#include "../include/errors.h"
#include "../include/tasks.h"
#include "../include/taskrunner.h"


int doNow, doLater;


int taskrunner(Task * TaskList, unsigned int listLen)
{
        int iter;


        printf("Running Tasks, %d\n", listLen);
        for(iter = 0; iter < listLen; iter++)
        {
                if( 0 == *TaskList[iter].runNow)
                {
                        printf("%s, %d\n", TaskList[iter].taskName, *TaskList[iter].runNow);
                }
        }
        return(iter);
}


Task tasks[] = {
        {"First_Task", &doNow},
        {"Second_Task", &doLater},
        {"Third_Task", &doNow},
};


#define NUM_TASKS sizeof(tasks)/sizeof(Task)


int runAllTasks(void)
{
        int Error;
        Error = 0;
        doNow = 0;
        doLater = 0;
        while(0 == Error)
        {
                Error = taskrunner(tasks, NUM_TASKS);
                if(doLater == 0)
                        Error = 0;
                doLater = 1;
        }
        return(Error);
}


int main()
{
        int Error;
        printf("Hello world\n");
        /* Initialize task list */
        /* Run the task list using the given tasks */
        printf("Final task result = %d\n", runAllTasks());
        return(0);
}

I get following error message any help how to remove it

C:\Users\Vij\Downloads\TaskTurner-master\TaskTurner-master\tasker\src>gcc -o runtask runtask.c

You probably have to #include <windows.h> in errors.h

I did changes

Code:

---

#include<stdio.h>
//#include "../include/errors.h"
#include<windows.h>
#include "../include/tasks.h"
#include "../include/taskrunner.h"

---

error

That looks impossible: you commented out the include of errors.h, so how could the compiler still be complaining about its content? It should be complaining about code that depends on what was declared in errors.h, or nothing at all.

Furthermore, your header files should bd self-contained. Consider:

Code:

---

#ifndef TASKRUNNER_H
#define TASKRUNNER_H
int taskrunner(Task * TaskList, unsigned int listLen);
 
 
#endif  // TASKRUNNER_H

---

What's Task? It is undeclared in this header. You should either declare it, or include the header that declares it.

I am trying to run code given in the example GitHub - EmbeddedApprentice/TaskTurner: A first, very short beginning for the TaskTurner.

When I unzip folder I get only three file taskrunner.h task.h runtask.c I don't see error.h in folder

once code will run so I can try to understand what's happening

You're right. Unfortunately, what this means is that the project that you've found has a missing file. You'll have to file a bug report or otherwise contact the maintainer to have it fixed.

EDIT:
Then again, it looks like this project was last updated 3 years ago, so it might not be actively maintained. May be worth a try to open an issue (i.e., file a bug report) anyway if you're really so interested in it, but given the quality of the code I'm not sure if it is really worth it.

That code is garbage and unfinished.
Why are you interested in it?

Okay so I will leave it here

I was looking some sample to create basic scheduler in c programming.
