Maybe your project is wrong and you spelt the file name wrongly (the file where "srt.h" is supposed to be is called something else)?

I took your code, copy-pasted it into main.c and srt.h and I do not have the same compilation error.

I have 20+ errors, such as undefined symbols, functions being called with the wrong number of arguments, etc.

When I separate the two source files of main.c and srt.h. I don't get that error. But in srtheap.c file, I have to include the preprocessor command #include "srt.h". I did use the command in srtheap.c file. But it gives me error of compilation terminated.
Here is the code:

/*
 *
 *  srt.h file
 *
 */



#include <string.h>
#include "srt.h"

#define MAX_BUF 256

#define swap(qx,qy,sz)                                              
do {                                                                
    char buf[MAX_BUF];                                              
    char *q1 = qx;                                                  
    char *q2 = qy;                                                  
    for (size_t m, ms = sz; ms > 0; ms -= m, q1 += m, q2 += m) {    
        m = ms < sizeof(buf) ? ms : sizeof(buf);                    
        memcpy(buf, q1, m);                                         
        memcpy(q1, q2, m);                                          
        memcpy(q2, buf, m);                                         
    }                                                               
} while (0)

void srtheap(void *, size_t, size_t, int (*)(const void *, const void *)){
    for(int i = nelem/2-1; i>=0; i--)
    srtheap(a, nelem, sizeof(TYPE), compare);

    for(int i = nelem - 1; i>=0; i--){
        swap(&arr[0], &arr[i]);
        srtheap(a, nelem, sizeof(TYPE), compare);
    }
}

void srtheap(int arr[], int nelem, int i){
    int largest = i;
    int left = 2 * i + 1;
    int right = 2 * i + 2;
    if(left < nelem &&arr[left] > arr[largest])
    largest = left;
    if(right < nelem &&arr[right] > arr[largest])
    largest = right;
    if(largest! = i){
        swap(&arr[i], &arr[largest])
        srtheap(arr[], nelem, largest);
    }
}
