Paul,

can you please compress and post your config.log ?
what is the OFED version you are running ?

on master, that fix did the trick on mellanox test cluster (recent OFED version) but did not
enable XRC on lanl test clusters (my best bet is an old OFED library)

Thanks

Gilles

Preliminary report:

1) I find that "ConnectX XRC support" is still not detected as it was in 1.8.4 and earlier:

    $ grep  'ConnectX XRC support'
    openmpi-1.*-icc-14/LOG/configure.log|  sort -u
    openmpi-1.8-linux-x86_64-icc-14/LOG/configure.log:checking if

    openmpi-1.8.7rc1-linux-x86_64-icc-14/LOG/configure.log:checking if
    ConnectX XRC support is enabled... no



2) I noticed a cosmetic "glitch" in the configure output:

    checking for working epoll library interface... checking if epoll can 
build... yes

    yes

This just means AC_MSG_{CHECKING,RESULT} macros are nested when they shouldn't be. There is nothing to suggest that the results of the configure probes are incorrect.

    Please test and let me know of any issues that surface. My intent
    is to release this next week.
