Found solution - add these lines to code

ex = X509V3_EXT_conf_nid(NULL, NULL, NID_subject_key_identifier, "hash");
X509_add_ext(x, ex, -1);
X509_EXTENSION_free(ex);

ex = X509V3_EXT_conf_nid(NULL, NULL, NID_authority_key_identifier, "keyid:always");
X509_add_ext(x, ex, -1);
X509_EXTENSION_free(ex);
