Hello guys, i have a problem with Zeus and Lazarus on Mac in an
attempt to connect to a firebird db. When you launch the program this
screen. What does it mean?

As the error describes: Your database is not available. It doesn't
exist or the path is wrong.

The second "format" issue occures, since the firebird.msg file to
format the massage couldn't be found. This happens, when the loaded
fbclient.dll/gds32.dll is not in the same directory where firebird was
installed.

Thanks, but I have installed firebird on my mac. Now where I'm going
to take the dll to put into the folder with my project?

Set the whole path of your fbclient.dll where it is installed in the
TZConnection.LibraryLocation.

E.g. On my windows machine it is:
LibraryLocation := "C:\Program
Files\Firebird\Firebird_2_5\bin\fbclient.dll"

where the messge file is located in:
C:\Program Files\Firebird\Firebird_2_5\firebird.msg

@xinyiman
First of all there is no dll under osx, secondly the firebird library
is located here:
/Library/Frameworks/Firebird.framework/Versions/A/Firebird. You should
copy the file to the user directory(/usr/local/lib/libfbclient.dylib).
This worked a few years ago(Mountain Lion), now things probably
changed, but you should give it a try anyway.

Thank you GetMem, now connection is ok, but when execute a simple
query return this error

Personally I newer saw this error before, google is not helping
either. I think it's a zeos issue, so try to connect to the database
with TIBConnection first. Just a test connection with a simple query.

I think it is a problem of Zeus. Because if I execute the query works,
but if I connect to the query a DBGrid creates the problem. Ideas?

You should ask on the zeos forum, they know the code better.
