Hi, typical problem with "unable to load" is dependency on another dll.
You can create small delphi x64 application and try to load this dll into
this application.

And you will see.

Subject: [firebird-support] UDF 64 bits




Hello... I think I've posted this question before, but now can't find
the thread... Anyway I still have the problem...

An UDF that worked fine in FB 32 bits, in 64 bits doesn't work

This is the DDL:

DECLARE EXTERNAL FUNCTION SG_DES
DOUBLE PRECISION,
CSTRING(50)
RETURNS DOUBLE PRECISION BY VALUE
ENTRY_POINT 'Descuentos' MODULE_NAME 'SGUDF';

SGUDF.DLL is in C:\Program Files\Firebird\Firebird_2_5\UDF

I get this message whe I try to execute the function:

can't format message 13:896 -- message file C:\Windows\firebird.msg not
found.
invalid request BLR at offset 59.
function SG_DES is not defined.
module name or entrypoint could not be found.

The DLL was rebuilded with Delphi XE2 for 64 bits...

thanks!
