Subject: Re: [OMPI devel] undefined references for rdma_get_peer_addr & rdma_get_local_addr

Jon / Steve -- can you comment?

I tested with OFED 1.2.5 (which is what I assume you meant) and got:

checking for rdma_get_peer_addr... no

Because that function is not defined in OFED 1.2.5. Running with OFED
1.3 (where the function does exist), I get:

checking for rdma_get_peer_addr... yes

Outside of all the configure complexity, can you write a simple
program that calls that function and have it compile and link properly?

I suppose we could change the AC_COMPILE_IFELSE in config/
ompi_check_openib.m4 to OMPI_LINK_IFELSE, but I'm a little confused as
to why it would compile successfully if the symbol rdma_get_peer_addr
is not declared anywhere (which it shouldn't be in OFED 1.2 or 1.2.5,
AFAIK)...
