I do not understand this error. Any ideas? Its from a firebird 1.5
database on windows i am trying to open it in linux:



matt@rr4linux /etc/init.d $ /opt/firebird/bin/isql -user sysdba -password ******
Use CONNECT or CREATE DATABASE to specify a database
SQL> connect /home/matt/opsim/branches/sysdata.fdb;
Statement failed, SQLCODE = -820

unsupported on-disk structure for file
/home/matt/opsim/branches/sysdata.fdb; found 32779, support 10

Many Thanks!
Matt
