Hi All,

Using openmpi-1.1.3b3, I've been attempting to build Open-MPI in
64-bit bit mode on a Mac Pro (dual Xeon 5150 2.66GHz with 1G RAM).
Using the following configuration options:

./configure --prefix=/usr/local/openmpi-1.1.3b3 \
--build=x86_64-apple-darwin \
CFLAGS=-m64 CXXFLAGS=-m64 \
LDFLAGS=-m64

The make goes fine, but in "make check" it hits an error in the "opal_if" test.

Searching the source code in opal/util/if.c shows that the error is
occuring with the
   ioctl(sd, SIOCGIFCONF, &ifconf)
call never returning a valid result (I tried increasing
MAX_IFCONF_SIZE, but that didn't help). There's a comment at the top
of the file that mentions some compiler magic (align=power, etc.) for
the 64-bit PPC version, but I'm at a loss about using it on a 64-bit
Intel platform.

Has anyone else had any experience with this?

(Note that 32-bit binaries compile and pass make check.)

Thanks,
jason
