我需要使用C和CUnit编写一个程序来测试一些简单的堆栈函数并使用“Makefile”但是当我尝试编译它时,我总是得到相同的错误。当我写“make”命令时,ubuntu上的终端显示了这个:

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'

我写的.h是:

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);

带主代码的.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函数:

    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);

    }

基本功能,push,pop等都是写的,但它们没有问题。它们以前用于我的另一个程序。

gcc -o编译并链接您的源代码,因此要么添加.c来实现函数,要么使用gcc -c单独编译,这不会链接源文件。
