我在Ubuntu下使用Eclipse。如何链接cmocka?
我刚刚安装cmocka:
Install the project...
-- Install configuration: "Debug"
-- Installing: /usr/lib/pkgconfig/cmocka.pc
-- Installing: /usr/lib/cmake/cmocka/cmocka-config.cmake
-- Installing: /usr/lib/cmake/cmocka/cmocka-config-version.cmake
-- Installing: /usr/include/cmocka.h
-- Installing: /usr/include/cmocka_pbc.h
-- Installing: /usr/lib/libcmocka.so.0.3.1
-- Installing: /usr/lib/libcmocka.so.0
-- Installing: /usr/lib/libcmocka.so
当我建立一个简单的测试项目中,我得到的链接错误。从这个代码
#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);
}
我得到这些错误:
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
./test_scripts/test_factorial.o: In function `test_factorial_zeo':
/home/me/workspace/unit_test_C_code_example_project/Debug/../test_scripts/test_factorial.c:10: undefined reference to `_assert_int_equal'
./test_scripts/test_factorial.o: In function `main':
/home/me/workspace/unit_test_C_code_example_project/Debug/../test_scripts/test_factorial.c:20: undefined reference to `_run_tests'
collect2: ld returned 1 exit status
make: *** [unit_test_C_code_example_project] Error 1
**** Build Finished ****
所以,看来我应该向cmocka库添加到链接器的路径。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 ****
我得到相同的结果与libcmocka.so.0.3.1,libcmocka.so.0和libcmocka.so
很显然,我做一些很基本的错误,但什么?
