As stated in a previous post, the upgrade to MariaDB made my system stop working. The reason is a missing libmysqlclient.so.15
I solved it by removing MariaDB and returning back to MySQL5
ipkg update
ipkg install mysql
set mysql root password
/opt/etc/init.d/S70mysqld stop
/opt/bin/mysqld_safe --skip-grant-tables
open a new terminal window
/opt/bin/mysql -u root
mysql> use mysql;
mysql> update user set Password=PASSWORD('newpassword') where
User='root';
mysql> exit
/opt/etc/init.d/S70mysqld stop
rm -f ~/.mysql_history
/opt/etc/init.d/S70mysqld start
Then the usual installation sequence for smatool.
