cddb and mci produce an ImportError

[flupke]

Hi,

i am in search of a cddb module for Python on windows. I stumbled upon 
http://sourceforge.net/projects/cddb-py but couldn't use it since the 
mci.dll is compiled against Python2.0.
So i'm trying to rebuild it using Dev-C++. I've succeeded in building a 
dll but when i try a test program it get this error:
http://sourceforge.net/projects/cddb-py

Traceback (most recent call last):
   File "cddtest.py", line 1, in ?
     import CDDB, DiscID
   File "C:\Python24\lib\DiscID.py", line 15, in ?
     import cdrom, sys
   File "C:\Python24\lib\cdrom.py", line 8, in ?
     import mci
ImportError: dynamic module does not define init function (initmci)

I had already some problems with the CDDB.py program since it used 
os.geteuid() and python gave an error for that too. These are the files 
i'm using and i'm not sure the content is correct. I used a dll project 
and copied and pasted the content of the original files from the cddb 
project in there in the hopes of getting it to work.

test program
========================================================================
import CDDB, DiscID

cdrom = DiscID.open()
disc_id = DiscID.disc_id(cdrom)

(query_status, query_info) = CDDB.query(disc_id)
(read_status, read_info) = CDDB.read(query_info['category'], 
query_info['disc_id'])

for i in range(disc_id[1]):
     print "Track %.02d: %s" % (i, read_info['TTITLE' + `i`])

I've included these libraries (linker options):
--no-export-all-symbols --add-stdcall-alias
C:/Dev-Cpp/lib/libwinmm.a
C:/Python24/libs/python24.lib
C:/Python24/libs/libpython24.a

It compiles fine and makes a mci.dll but as i said, i get the 
ImportError when i run it.

Any ideas?

Thanks,
Benedict
