In Windows it works, but not in Linux.

I had to add to the source code in zabstractrodataset.pas
Had to add ftUnknown.

{$IFEND CompilerVersion >= 21}
{$IFEND CompilerVersion >= 20}
{$IFEND CompilerVersion >= 18}
{$ENDIF FPC}
,ftUnknown{ftObject},ftUnknown{ftObject},ftUnknown{ftObject},ftUnknown
{ftObject},ftUnknown{ftObject},ftUnknown{ftObject},ftUnknown{ftObject}
);

I didn't know what to use other than ftUnknown, and i don't know why
these elements is missing when using it in Linux.
I also know this is not correct using only unknown, but i don't know
what to use here.

I used the latest Zeos and Lazarus 3.

I thought this may be good info for other that cannot get Zeos to work
on Linux because of this.

Use fpc-3.2.2 instead of fpc-3.2.3 or trunk.

But don't forget, fpc-322 will not work with openssl 3 and most up to
date systems have openssl 3 now.

One (very ugly) solution to that is to create a symlink called
libssl.so from libssl.so.3. Usually works but no guarantee !

Ohh!!!
Then i just will have it like i have done. i use this.
I don't need these "unknown" elements i created in my app. I really
don't know what they should be, but i only need the string type, so it
is working good after i added it.
I could go deeper in the source and figure out maybe, but it's
working.

Thanks for this info, very useful indeed.
