I tried both versions (relative and absolute paths) but both gave me
the same error. The files are in the default UDF directory.

I declared the UDF like this:

DECLARE EXTERNAL FUNCTION STRLEN
CSTRING(32767)
RETURNS INTEGER BY VALUE
ENTRY_POINT 'IB_UDF_strlen' MODULE_NAME 'id_udf'

I assume that's correct?

Any ideas what else it could be?
