That's weird, 'struct ibv_exp_release_intf_param' must be defined in /usr/include/infiniband/verbs_exp.h, itself included by infiniband/verbs.h, both normally part of the libibverbs-devel package above. Make sure you don't have an old version of infiniband/verbs.h somewhere else such as in /usr/local/include after a manual compilation of libibverbs. -- Adrien Mazarguil 6WIND
