[ofa-general] makefile problem in using librdmacm and libverbs

[yangdong]

I have some troubles when i was use libverbs and rdmacm. I make a
makefile for my amp subsystem,
you can see my makefile as follows. The key is LDFLAGS = -lm -lpthread
-libverbs -lrdmacm, i make
my makefile following Makefile in perftest, this is different from
makefile in librdmacm
(~/OFED-1.2/SOURCES/ofa_user-1.2/src/userspace/librdmacm). I adopt this
style, but my problem came,
that is after i do:
rdma_create_event_channel,rdma_create_id, rdma_resolve_addr,
rdma_resolve_route, ibv_alloc_pd, ibv_create_cq,
when i invoke ibv_req_notify_cq, Segmentation fault occur, because
cm_id->verbs->ops.req_notify_c is not exist.

who can give me some advice, how write my makefile to use librdmacm and
libverbs correctly, thanks a lot!
