我需要用C和CUnit編寫一個程序來測試一些簡單的堆棧函數,並使用「Makefile」,但是當我嘗試編譯它時,我總是會得到相同的錯誤。在Ubuntu終端顯示這個時候我寫了 「make」 命令:CUnit(undefined reference)
gcc -o Pilhaa_teste.o Pilhaa_teste.c -lcunit
/tmp/ccLqNqAx.o: In function `main':
Pilhaa_teste.c:(.text+0x21): undefined reference to `clean_suite1'
Pilhaa_teste.c:(.text+0x26): undefined reference to `init_suite1'
Pilhaa_teste.c:(.text+0x50): undefined reference to `testaTOP'
,我寫的是.H:
typedef struct No {
struct No *prox;
int info;
}no;
typedef struct pilha {
no *topo;
}Pilha;
int init_suite1(void);
int clean_suite1(void);
void testaTOP(void);
/*create empty stack*/
Pilha *cria_pilha(void);
/*add one element to the stack*/
void push (Pilha *p, int valor);
/*free first element of stack*/
void pop (Pilha *p);
/*print and find first element*/
int top (Pilha *p);
/*free stack*/
void libera(Pilha *p);
/*print stack*/
void imprime(Pilha *p);
與主代碼.C:
#include <stdlib.h>
#include <stdio.h>
#include "pilha.h"
#include "CUnit/Basic.h"
int main(){
CU_pSuite pSuite = NULL;
if (CUE_SUCCESS != CU_initialize_registry())
return CU_get_error();
pSuite = CU_add_suite("Suite_1", init_suite1, clean_suite1);
if(NULL == pSuite){
CU_cleanup_registry();
return CU_get_error();
}
if(NULL == CU_add_test(pSuite, "test of top()", testaTOP)){
CU_cleanup_registry();
return CU_get_error();
}
CU_basic_set_mode(CU_BRM_VERBOSE);
CU_basic_run_tests();
CU_cleanup_registry();
return CU_get_error();
}
和clean_suite1,init_suite1和testaTOP功能:
static Pilha *p = NULL;
int init_suite1(void){
push(p, 6);
if(p!=NULL)
return 0;
else
return 1;
}
int clean_suite1(void){
pop(p);
if (p == NULL)
return 0;
else
return 1;
}
void testaTOP(void){
Pilha *p = NULL;
push (p, 6);
if (p != NULL){
CU_ASSERT(top(p) == 6);
push (p, 7);
if (p != NULL)
CU_ASSERT(top(p) ==7);
}
no *aux = p->topo->prox;
free(p);
free(aux);
}
的基本功能,推,流行等寫入,但沒有與他們的問題。他們以前用於我的另一個程序。
