entry point not found error

[Alan Darlington]

I created a program hellow.cob:

    id division.
       program-id. hellow.
       ENVIRONMENT DIVISION.
       CONFIGURATION SECTION.
       REPOSITORY.
           FUNCTION hello
           FUNCTION ALL INTRINSIC.
       data division.
       working-storage SECTION.
       01  ws-dummy    pic x.       
       procedure division.
           display 'calling hello'.
           call 'hello' using ws-dummy.
           display 'returned from hello'.

and a subroutine hello.cob:

       id division.
       FUNCTION-ID. hello.
       data division.
       LINKAGE SECTION.
       01 lk-dummy    pic x.
       01 lk-dummy2   pic x.        
       procedure division using lk-dummy RETURNING lk-dummy2.
           display 'from subroutine -- hello world!'.
           end FUNCTION hello.

Both compile successfully giving hellow.exe & hello.dll (using -x & -m options for cobc) in c:\ gnucobol.
When I execute hellow.exe from \gnucobol I get:

calling hello
libcob: error: entry point 'hello' not found

What have I not done or done wrong?

I installed gnucobol using Arnold Trembley's process for Windows with ISAM.

What's the FUNCTION-ID. hello. in the .dll - shouldn't that be Program-id. hello. ??.

[Simon Sobisch]

As David pointed out: either use PROGRAM-ID and CALL or FUNCTION-ID and use a function (note: in the later case: ensure that you either COB_PRE_LOAD the dll or have it all upper-case).
