QNX 6.20 and Mysql

I have installed mysql-3.23.53-bin.tar.gz under /
Under /opt/mysql/bin i have execute mysql_install.db OK
The tables are installed under /opt/mysql/var/mysql :
host.frm user.frm etc
I launch safe_mysqld :
starting mysqld daemon with databases from /opt/mysql/var
mysql ended
The data in /opt/mysql/var/jlwager.wager.fr.err are :
31120 16:09:42 mysqld started
31120 16:09:42 /opt/mysql/libexec/mysqld: Can’t create/write to file ‘/opt/mysql/var/jlwager.wager.fr.pid’ (Errcode: 13)

31120 16:09:42 /opt/mysql/libexec/mysqld: Can’t find file: ‘./mysql/host.frm’ (errno: 13)
31120 16:09:42 /opt/mysql/libexec/mysqld: Normal shutdown

31120 16:09:42 /opt/mysql/libexec/mysqld: Error on delete of ‘/opt/mysql/var/jlwager.wager.fr.pid’ (Errcode: 2)
31120 16:09:42 mysqld ended
jlwager.wager.fr is the hostname.
Thank you for your help

make sure you create a user mysql with group mysql.
then make /opt/mysql/var owned by mysql:mysql

hm, this looks better:
