Hi Team, When using mariadb-10.3.38, after upgrading Openssl from 1.1.1 to 3.1 strange compilation errors occur. /xxxx/bin/ld: ../build/lib/libyyyy.so: undefined reference to `server_mysql_error' /xxxx/bin/ld: ../build/lib/libyyyy.so: undefined reference to `server_mysql_fetch_row' /xxxx/bin/ld: ../build/lib/libyyyy.so: undefined reference to `server_mysql_num_rows' /xxxx/bin/ld: ../build/lib/libyyyy.so: undefined reference to `server_mysql_select_db' /xxxx/bin/ld: ../build/lib/libyyyy.so: undefined reference to `server_mysql_num_fields' /xxxx/bin/ld: ../build/lib/libyyyy.so: undefined reference to `server_mysql_real_connect' /xxxx/bin/ld: ../build/lib/libyyyy.so: undefined reference to `server_mysql_close' /xxxx/bin/ld: ../build/lib/libyyyy.so: undefined reference to `server_mysql_init' /xxxx/bin/ld: ../build/lib/libyyyy.so: undefined reference to `server_mysql_free_result' /xxxx/bin/ld: ../build/lib/libyyyy.so: undefined reference to `server_mysql_store_result' collect2: error: ld returned 1 exit status make[1]: *** [../rules.Make:461: cli] Error 1 libyyyy.so uses shared library libmysqlclient.so and both of them use mysql_xxxx. I don't know why prefix "server_" is added. I found a simliar issue where valgrind is used. But in my scenario valgrind is not used. https://jira.mariadb.org/browse/MDEV-28958?page=com.atlassian.jira.plugin.sy... Any constructive suggestions are welcomed. Many thanks in advance.
