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

Please see the attached file for program reference.

Your module is compiling against the vendor kernel sources instead of MOFED. You might take a look on the other projects that compile against MOFED, for example Lustre.
