Witam,
Mam problem z kompilacją kodu zawartego w break-short.c.
Korzystam ze środowiska Linux WSL (Ubuntu 16.04 zainstalowanego na Windows Server 2019) z GCC 7.3.0
Kompilacje przeprowadzam poniższą komendą, która przeprowadza kompilację bezproblemowo w przypadku gdzie część kodu to #define GSTEP (1<<25) ):
gcc -o break-short.exe -O2 -I secp256k1/src/ -I secp256k1/ break_short.c -lgmp
Przy zmianie tej części na #define GSTEP (1UL<<60) cały kod wygląda tak jak poniżej:
#include "libsecp256k1-config.h"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include "include/secp256k1.h"
#include "secp256k1.c"
/* giant steps are 2^25 */
#define GSTEP (1UL<<59)
#define NUMPUBKEYS 60
unsigned char rawpubkeys[NUMPUBKEYS][33] = {

Kompilacja jest niemożliwa a otrzymany wynik błędu to
break-short.c:92:17: error: size of array ‘table’ is too large
hashtable_entry table[HASH_SIZE];
Moje pytanie brzmi - w jaki sposób mogę skutecznie to skompilować? i/lub ewentualnie jak edytować kod w inny sposób żeby możliwe było jego finalne wykonanie?
