trouble swigging a library

Hi all, 

I would like to use Swig to make a Python wrapper to a library
I wrote in C. The library is installed in /usr/lib and works fine
with C. It's an access library for USB HID devices without requiring
kernel support. Now I need to use it from Python...

I thus created a .i file for the API and compiled it:

  swig -python hid.i

  cc -fpic -I/usr/include/python2.3/ -I../include \
    -DHID_INTERNAL -c -o hid_wrap.o hid_wrap.c

No errors.

I then linked it:

  ld -shared -lusb -lhid hid_wrap.o -o hid.so

Also, no errors.

Now I fire up python and try to import the module, but that fails:

  Traceback (most recent call last):
    File "./startup.py", line 3, in ?
      from hid.so import *
  ImportError: dynamic module does not define init function (inithid)

It seems that everything compiled fine though:

  $ ldd hid.so
        libusb-0.1.so.4 => /usr/lib/libusb-0.1.so.4 (0x40010000)
        libhid.so.0 => /usr/lib/libhid.so.0 (0x40019000)
        libc.so.6 => /lib/tls/libc.so.6 (0x40026000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

What am I doing wrong?

Thanks for any help!

If you want to download the library in question:

  cvs -d :pserver:anoncvs@xxxxxxxxxxxx:/home/cvs/external login
  [empty password]
  cvs -z3 -d :pserver:anoncvs@xxxxxxxxxxxx:/home/cvs/external co libhid

You can find ./swig in there...
