Sorry form my english, I am Italian..... They are successful to install mysql-4.1.7 on o.s. solaris 8 thanks to the suggestions of Gleb Paharenko.
Now I have this problem: When start the command "mysqld_safe &" mysql start and ended immediately. In the log file I find this error: "041115 20:43:42 mysqld started 041115 20:43:42 InnoDB: Operating system error number 13 in a file operation. InnoDB: The error means mysqld does not have the access rights to InnoDB: the directory. InnoDB: File name ./ibdata1 InnoDB: File operation call: 'create'. InnoDB: Cannot continue operation. 041115 20:43:42 mysqld ended" Help me, thanks Alessio
