Bom dia!Estamos migrando banco de dados do Firebird 3 para o 5 e recebemos a mensagem:
gbak: WARNING:function STRLEN is not defined
gbak: WARNING:    module name or entrypoint could not be found
gbak: WARNING:    function SUBSTR is not defined

gbak: WARNING:    module name or entrypoint could not be found
gbak: WARNING:    function MOD is not defined
gbak: WARNING:    module name or entrypoint could not be foundExecutamos o script conforme recomendado no livro sobre migração para o Firebird 4 do Cantu:/opt/firebird/bin/isql -user sysdba -pas 4b6f4194 -i /opt/firebird/misc/upgrade/udf/udf_replace.sql banco.fdb
e isso resolve quase tudo, continua dando mensageem nas funções MOD e ABS, como posso resolver isso?
