我在 Ubuntu 下使用 Eclipse。
我刚刚安装了 cmocka:
Install the project...
-- Install configuration: "Debug"
-- Installing: /usr/lib/pkgconfig/cmocka.pc
-- Installing: /usr/lib/cmake/cmocka/cmocka-config.cmake

-- Installing: /usr/lib/libcmocka.so.0
-- Installing: /usr/lib/libcmocka.so
当我构建一个简单的测试项目时,我得到了链接器错误。从这段代码
#include <stdarg.h>
#include <stddef.h>
#include <setjmp.h>
#include <cmocka.h>
#include "factorial.h"
static void test_factorial_zeo()
{
assert_int_equal(factorial(0), 1);
}
int main(int argc, char **argv)
{
const UnitTest tests[] =
{
unit_test(test_factorial_zeo),
};
return run_tests(tests);
}
我收到这些错误:
make all
Building target: unit_test_C_code_example_project
Invoking: GCC C Linker
gcc -o "unit_test_C_code_example_project" ./test_scripts/test_factorial.o ./software_under_test/factorial.o

所以,看来我应该将 cmocka 库添加到链接器路径中。但后来我得到
make all
Building target: unit_test_C_code_example_project
Invoking: GCC C Linker
gcc -o "unit_test_C_code_example_project" ./test_scripts/test_factorial.o ./software_under_test/factorial.o -llibcmocka.so.0.3.1
/usr/bin/ld: cannot find -llibcmocka.so.0.3.1
collect2: ld returned 1 exit status
make: *** [unit_test_C_code_example_project] Error 1
**** Build Finished ****
我使用 libcmocka.so.0.3.1、libcmocka.so.0 和 libcmocka.so 得到相同的结果
显然,我做错了一些非常基本的事情,但是什么?
