Hmm, so it's either setting up a totally new workspace or replacing with
OMPI_LINK_IFELSE would get me the right configure check. I think the
latter is the fix to my problem. I assume make all should work now
unless I'll tell you otherwise...

I am trying Jeff's suggestion to replace OMPI_COMPILE_IFELSE to
OMPI_LINK_IFELSE. Will let you know.

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
For me it seems to be running with 1.2.5.

No rmda_get_peer_addr or rmda_get_local_addr in these .so's, assumingly
they are coming from there.

And I don't see rdma_get_peer_addr appeared in the
/opt/ofed/include/rdma/rdma_cma.h either. Not knowing how it actually
know about the interface (and it's not inline) there.
Outside of all the configure complexity, can you write a simple
program that calls that function and have it compile and link properly?
These are the references of rmda_get_peer_addr from the config.log:
47858 configure:120941: checking for rdma_get_peer_addr

Here's my program, not sure if it's doing it correctly. I am no m4
expert, so how do I run the ompi_check_openib.m4 independently and see
the conftest.c??
login3% cat mytest.c
#include "rdma/rdma_cma.h"
int main (void) {
void *ret = (void*) rdma_get_peer_addr((struct rdma_cm_id*)0);
return 0;
}
It gives me a warning if I just try to create an object, which is what I
see in the config.log.
login3% pgcc -c -g -D_REENTRANT -I/opt/ofed/include mytest.c
PGC-W-0155-Pointer value created from a nonlong integral type (mytest.c: 3)

0
But trying to create an executable would give me the error.
login3% pgcc -g -D_REENTRANT -I/opt/ofed/include mytest.c -o mytest

Hmm, any clues, comments?
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)...

Crud. Can you send me your config.log? I don't know why it's able
to find rdma_get_peer_addr() in configure, but then later not able
to find it during the build - I'd like to see what happened
during configure.

Hi Jeff,
It seems that the cpc3 merge causes my Ranger build to break. I
believe it is using OFED 1.2 but I don't know how to check. It
passes the ompi_check_openib.m4 that you added in for the
rdma_get_peer_addr. Is there a missing #include for openib/ofed
related somewhere?
