Dear friends,
This is my first cpp module working with mySQL.
It looks like the error is located in
MYSQL *m=mysql_real_connect(myDB, host, user, passwd, ...
There is a way to find out step by step which parameters is wrong?
I am working with Fedora core 3
and MySQL 3.23.58
Thanks,
MT

both your host _and_ unix_socket are null, this could not work if I
understand well the doc. Use either "127.0.0.1" for host if networking
is enable in mysql, or the full path to the unix socket (defaut
/var/lib/mysql/mysql.sock)
