I try to create an udf written in delphi, but I always get the same error:

invalid request BLR at offset 60 function TESTECHO is not defined module name or entrypoint could not be found

I use Delphi 2010. The function is declared like this:

function TESTECHO(AValue: Integer): Integer; cdecl; export;


and in my database I declare it like this:

DECLARE EXTERNAL FUNCTION TESTECHO
INTEGER
RETURNS INTEGER BY VALUE
ENTRY_POINT 'TESTECHO' MODULE_NAME 'Rankings5Firebird';


My server is on Windows: "WI-V6.3.0.26074 Firebird 2.5", 32bit version.

The DLL file is in the fbserver.exe directory.

Are there any special options I have to check when I compile my DLL with Delphi?

Or what else could be wrong?
