How to link and use CL and TL library?

[MoFHeka]

When I link libucc_tl_self, libucc_tl_ucp, libucc_cl_hier and libucc_cl_basic to the test code, a core dump occurred.
Maybe I made a mistake. Unlink the UCX, is the program only needed to link libucc can already use CL, TL, EC, MC and other features?
When use static linking to libucc, the program raise error.

main: ucc_examples/cmake/main.cpp:9: int main(int, char**): Assertion `st == UCC_OK' failed.
Aborted (core dumped)

main.cpp

#include <ucc/api/ucc.h>
#include <cassert>

int main(int argc, char *argv[]) {
  ucc_status_t st;

  ucc_lib_config_h lib_config;
  st = ucc_lib_config_read(nullptr, nullptr, &lib_config);
  assert(st == UCC_OK);

  ucc_lib_params_t lib_params = {};
  lib_params.mask = UCC_LIB_PARAM_FIELD_THREAD_MODE;
  lib_params.thread_mode = UCC_THREAD_MULTIPLE;

  ucc_lib_h lib;
  st = ucc_init(&lib_params, lib_config, &lib);
  assert(st == UCC_OK);

  ucc_lib_config_release(lib_config);
  ucc_finalize(lib);
  return 0;
}
