Question

我尝试使用libcheck构建一个简单的示例，但在使用pkg-config报告的标记时无法构建。

我的文件：tests / test.c

#include <stdlib.h>
#include <check.h>

START_TEST(zero)
{
        int z = 0;
        ck_assert_int_eq(0, z);
}
END_TEST

Suite* suite_zero(void)
{
    Suite* s;
    TCase* tc;
    s = suite_create("suite_zero");
    tc = tcase_create("zero");
    tcase_add_test(tc, zero);

    suite_add_tcase(s, tc);
    return s;
}

int main(void)
{
    int number_failed;
    SRunner* sr;

    Suite* s_zero = suite_zero();

    sr = srunner_create(s_zero);

    srunner_run_all(sr, CK_NORMAL);
    number_failed = srunner_ntests_failed(sr);
    srunner_free(sr);
    return (number_failed == 0) ? EXIT_SUCCESS : EXIT_FAILURE;
}

我的系统：

$ cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu 16.04 LTS"
$ gcc --version
gcc (Ubuntu 5.4.0-6ubuntu1~16.04.2) 5.4.0 20160609

$ pkg-config --version
0.29.1

当我尝试使用pkg-config报告的标志和库来构建我的测试时：

$ pkg-config --cflags --libs check
-pthread -lcheck_pic -pthread -lrt -lm -lsubunit
$ gcc -pthread -lcheck_pic -pthread -lrt -lm -lsubunit  -g tests/test.c -o tests/zero
/tmp/ccRV2kLw.o: In function `zero':

/Code/tests/test.c:33: undefined reference to `srunner_ntests_failed'
/Code/tests/test.c:34: undefined reference to `srunner_free'
collect2: error: ld returned 1 exit status

Libcheck由apt安装，库和头文件分别位于典型位置/ usr / lib和/ usr / include。但它似乎无法找到。我为什么有点难过。有什么想法吗？

感谢。

尝试在编译命令之后添加pkg-config报告的标志，如answer和pkg-config的文档所示。编译器需要知道它试图将库链接到之前的文件，以便可以适当地应用这些标志。

gcc -g test.c -o test -pthread -lcheck_pic -pthread -lrt -lm -lsubunit

或更简洁

gcc -g test.c -o test `pkg-config --cflags --libs check`

libcheck测试无法链接
