cannot insmod sculld in ldd3

[Ali Aminian]

Hello
when i try to insmod sculld insmod prints this error message:
insmod: ERROR: could not insert module ./sculld.ko: Invalid parameters

i checked dmsg and it says:
[12073.858764] sculld: no symbol version for unregister_ldd_driver
[12073.858767] sculld: Unknown symbol unregister_ldd_driver (err -22)
[12073.858780] sculld: no symbol version for register_ldd_device

[12073.858794] sculld: no symbol version for register_ldd_driver
[12073.858795] sculld: Unknown symbol register_ldd_driver (err -22)

these functions are defined in lddbus and i have insmod lddbus.

can anyone tell me what is wrong.
thank you.
