does zeos8 support firebird v. 2.1?

[peppepolpo]

I have a legacy application that uses firebird v. 2.1 32bits.

The application compiles and works ok using Lazarus 2.2.4 and zeos 7.2.14.

I tried to upgrade my zeos package to v. 8 because I am interested in the new ZTransaction component.

Alas! At runtime I get the error 'database driver not found'.

See

Of course the driver is there (where the old TZConnection correctly finds it)

I realized that the old 'firebirdd-2.1' protocol is no more in the picklist of the new TZConnection, so I changed it to 'firebird'.

No joy.

I set 'FirebirdAPI=legacy' in the connection properties.

No joy. The error stays.

I order to keep working, I had to go back to zeos v. 7.2.14

Any help?

"database driver not found" means exactly that. Which value do you set to the TZConnection.Protocol property?

To me it seems that you use something like the old "firebird-21" protocol. Just switch to "firebird".

property 'protocol' was set to 'firebird' (I specified that).

Anyway I update the Lazarus version and ev works ok now.

Thank you
