lazarus 2.x and Firebird 3 emb
lazarus / 16-Databases

I try to set up a firebird 3 embedded connection in lazarus. Firebird
has a different design than 2.5. The engine12.dll has become the new
fbembed.dll. What have I done:
- firebird 3 downloaded 64 bits
- Lazarus 64 bits installed and started up.
- engine12.dll renamed to fbclient.dll (SQLdb does not know the new
engine name)
- Placed an IBConnection and SQLTransaction on the Form.
- a database connected.
- e.v.t. username / ww entered (if that is not necessary for
embedded).

If I then set the property connected of IBconnection to true, it comes
with the message that fbclient / gds32 / fbembedded.dll is not found.

It does work with Firebird 2.5.

Can Firebird 3 emb work with Lazarus 2.x / FPC 3.04. And if so, what
should you do for it?

Nothing should be renamed, imo:
- the fbclient.so library is the network client for Firebird server on
Linux.
- the old libfbembed.so is now implemented as a plug-in library:
engine12.so (that's how it is).

I don't think renaming the Firebird 3's libraries will help you.

You're absolutely right. I had to copy the plugin directory to the
directory of my exe. And then the original fbclient.dll is used.

Hi.
I copied plugin directory as a directory then as a single files into
my bindir but still have that message.
Where I'm making a mistake?
Fedora30

Your mistake is following in Linux directions intended for Windows

For Linux, installing the Firebird libs as you would any other (for
Fedora that would be with yum, wouldn't it? or the normal package
manager) should be enough.

Thank You.
Sorry I was at work. Later is dnf. This is clean install from repos
and it does  not work

OK. Just install libfbclient devel package.
For now it has some compatibility problems with TIBConnection, so I
think I have to downgrade.
Thank You.
