Libyang utest_plugins failed, while all remaining ones pass.

[mus19f1a]

There are a failed test case "utest_plugins" where the libyang "devel" branch directly cloned into a arm based device and build with cmake 3.18.2 and gcc 10.2.0

Any idea for the reason of the error or to solve the issue?

Thank you in advance.

Here is the test log:

I am guessing the plugin is not found because of those ?? in the path. Can you paste the paths in build/tests/tests_config.h? Can you post the output of running cmake from scratch?

[mus19f1a]

sorry for the inconvenience, ?? marks is not error or bug, I just replace the username with "??", I fixed it now.

Paths in the ../build/tests/test_config.h is as follows:

#ifndef LYTEST_CONFIG_H_
#define LYTEST_CONFIG_H_

#define TESTS_SRC "/home/st/libyang/tests"
#define TESTS_BIN "/home/st/libyang/build/tests"

#define TESTS_DIR_MODULES_YANG TESTS_SRC"/modules/yang"

/**
 * @brief Macro for support of callgrind header and macros.
 */
/* #undef HAVE_CALLGRIND */

#endif /* LYTEST_CONFIG_H_ */

There are no path related issue I think.

Here is the cmake output from scratch;

Right, try changing this macro to 0 and rerun the test, you should see the actual error message.

[mus19f1a]

I switched to another setup, as I going back to the one that error exist I will add the actual error messages as you suggest.

is it possible utest_plugins to need libsystemd which are not exists in the running operating system?

No, I do not think so.
