c - "undefined reference to `_cmocka_run_group_tests'" when running sample CMocka test -


i installed cmocka testing framework , tried sample code:

#include <stdarg.h> #include <stddef.h> #include <setjmp.h> #include <cmocka.h>  /* test case nothing , succeeds. */ static void null_test_success(void **state) {     (void) state; /* unused */ } int main(void) {     const struct cmunittest tests[] = {             cmocka_unit_test(null_test_success),     };     return cmocka_run_group_tests(tests, null, null); }

but when try compile following error:

$ gcc -o tests tests.c     /tmp/ccbwaxrr.o: in function `main':     tests.c:(.text+0x5e): undefined reference `_cmocka_run_group_tests'     collect2: error: ld returned 1 exit status

what missing?

including header files provides forward declaration of functions. function definitions, need link library.

you can use -l option gcc link required libarary. may need use -l option provide path library.
