Question

我有这些简单的源文件：

标头文件

//header.h
#ifndef HEADER_H
#define HEADER_H

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

void test_uint_to_mpz();

#endif

实施档案

//src.c
#include "header.h"

void test_uint_to_mpz() {

   char hex_string[200];
   uint64_t var;
   mpz_t mpz_var;
   mpz_init(mpz_var);

   printf("Please enter a hex string that fits a variable uint64_t : ");
   scanf("%s",hex_string);

   var = (uint64_t)strtol(hex_string,NULL,16);
   mpz_set_ui(mpz_var,var);

   printf("Your input value was: %llx\n",var);
   printf("The mpz equivalent is: ");
   mpz_out_str(stdout,16,mpz_var);
   printf("\n");

   mpz_clear(mpz_var);

}

主要

//main.c
#include "header.h"

int main(int argc, char** argv) {
   test_uint_to_mpz();

   return 0;
}

然后我尝试使用这个简单的行进行编译：

gcc src.c main.c -L/user/lcg/lib -o numericalTest -I./ -lgmp -O3 -static

因为我想使用静态链接。对我来说很好，我很确定gmp的安装很好（参见命令行中的-L选项）。

然而，我有：

哪里可能是问题？

更新：我发布了makefile

CC=gcc
SRCS=src.c main.c
HEADER=header.h
OBJ_FILES=$(addsuffix ./,(basename $(SRCS)))
INCLUDES=-I./
FLAG=-lgmp -O3
output : $(SRCS) $(HEADER)
    $(CC) $(SRCS) -L/user/lcg/lib -o numericalTest $(INCLUDES) $(FLAG) -static
clean :
    rm *.o

GMP，功能的多重定义
