|Subject||64 bit UDF DLL problem on Windows|
I hope someone can help me because I'm running out of ideas.
I have an UDF collection written in C language. It works fine on the Linux server (Firebird version is: firebird-superclassic-126.96.36.199020.0-1.el7.x86_64)
I just simply compiled it with gcc, copied the output .so file to Firebird's UDF folder and it just works.
Now i want to use this UDF on my Windows development laptop as well, so testing would be faster. Firebird installed on my laptop is: 188.8.131.52050, the 64 bit version
I took the same C file, compiled it with MinGW 64 bit compiler, copied the output to Firebird's UDF folder, declared in the database like:
DECLARE EXTERNAL FUNCTION addnumbers
RETURNS INTEGER BY VALUE
ENTRY_POINT 'sum' MODULE_NAME 'sampledll';
Then i run this select:
SELECT addnumbers(5, 7) FROM rdb$database
I get this error msg:
can't format message 13:896 -- message file C:\Windows\firebird.msg not found.
invalid request BLR at offset 36.
function ADDNUMBERS is not defined.
module name or entrypoint could not be found.
I also restarted Firebird, but still no success.
Do you have ideas why it cannot find my UDFs?
How could i find more detailed information? (Like it doesn't find the file? Or there is a problem finding the function in the file? Or are there compatibility issues? Or anything else?)
