    not able to compile the kernel client module


      we have mellanox HCA connected with Server. We have installed OFED distribution in our Server . i am trying to write kernel client module to access the infiniband device using the RDMA stack. but i am getting some error  while insmod my module. please help me anyone who already worked in this error.




      insmod: ERROR: could not insert module Client.ko: Invalid parameters

      Dmesg :


      [16266.034500] Client: disagrees about version of symbol ib_unregister_client

      [16266.034508] Client: Unknown symbol ib_unregister_client (err -22)

      [16266.034520] Client: disagrees about version of symbol ib_register_client

      [16266.034523] Client: Unknown symbol ib_register_client (err -22)


      i have searched in this error in internet. they mentioned like compilation with improper header problem. i am not able to understand properly.

      Please clarify me more and provide me the sample makefile to compile this
