Why aren't you just using the Ubuntu 20.04 packaged version instead?

Also, did you install the headers for libmysqlclient properly as

well?

What does /test/core/mariadb/includes/ or

/test/core/includes/... show?

Hi John,

i just want to manage all the software manually, use own directorie-structur and have all the programs in one place, deepen my understanding how these programs work and build these programs only with the components i need.

The content of "/test/core/mariadb/include/mysql" is:

errmsg.h ma_list.h ma_pvio.h mariadb/ mariadb/ma_io.h mariadb_com.h mariadb_ctype.h mariadb_dyncol.h mariadb_rpl.h mariadb_stmt.h mariadb_version.h ma_tls.h my_config.h my_global.h mysql/ mysql/client_plugin.h mysql/plugin_auth_common.h mysql/plugin_auth.h mysql_com.h mysqld_error.h mysql.h mysql_version.h my_sys.h server/...
