Ben and Paul,
Thanks for the report !
it looks like a simple typo (e.g. ')' instead of ','
the attached patch is for v1.8
in order to use it, you need recent autotools (see
http://www.open-mpi.org/source/building.php)
apply the patch, run autogen.pl, and then configure, make, make install
i am now double checking this
Cheers,
Gilles

I just gave the whole 1.8 series a spin and it looks like "ConnectX
XRC" configure logic has been broken since 1.8.5, but worked in 1.8.4:

In addition to fixing the error in the configure logic, I wonder if
anyone has thought on mechanisms to detect regressions of this sort?

Hi,
I just finished building 1.8.6 and master on our cluster and
noticed that
for both, XRC support wasn't being detected because it didn't
detect the
IBV_SRQT_XRC declaration:
checking whether IBV_SRQT_XRC is declared... (cached) no
...
checking if ConnectX XRC support is enabled... no
checking if ConnectIB XRC support is enabled... no
Both of these builds had --enable-openib-connectx-xrc. Having a
look in the
config.log, I found this:
configure:191690: checking whether IBV_SRQT_XRC is declared

configure:191690: $? = 1
If you have a look at the test program, the failure is because it
forgets to
include the infiniband/verbs.h header, and sure enough the
configure script
bears this out:
ac_fn_c_check_decl "$LINENO" "IBV_SRQT_XRC"
"ac_cv_have_decl_IBV_SRQT_XRC" "$ac_includes_default"
Changing "$ac_includes_default" to "#include <infiniband/verbs.h>" and
reconfiguring allows it to detect this declaration and then enable
support
for XRC:
checking whether IBV_SRQT_XRC is declared... (cached) yes
...
checking if ConnectX XRC support is enabled... yes
checking if ConnectIB XRC support is enabled... yes
Cheers,
Ben
