compile error

hi，i meet some errors when compile the code. After I type "make build && cd build && cmake .."

it shows:

How can i fix it? Thanks

It is likely that the current rdma_bench is not compatible with your libibverbs version. I also encountered the same problem as you. I solved it by modifying part of the code, for example: ibv_exp_modify_qp changed to ibv_modify_qp. The attachment is my code modification patch file, I hope it can help you.

Helped me when I do cmake, although there's more ERRORs poping up when I run the ./run-machine.sh later. I am considering if that's a problem with my system.
