openmpi 2.1.0 fails to build on s390x

opoplawski commented 7 years ago

Thank you for taking the time to submit an issue!

Background information

What version of Open MPI are you using? (e.g., v1.10.3, v2.1.0, git branch name and hash, etc.)

2.1.0

Describe how Open MPI was installed (e.g., from a source/distribution tarball, from a git clone, from an operating system distribution package, etc.)

Building Fedora openmpi package

Please describe the system on which you are running

Operating system/version: Fedora rawhide

2.0.2 builds fine. With 2.0.2 I see:

checking if user requested CMA build... no

With 2.1.0 I see:

Transports
-----------------------
Cray uGNI (Gemini/Aries): no
Intel Omnipath (PSM2): no
Intel SCIF: no
Intel TrueScale (PSM): no
Mellanox MXM: no
Open UCX: no
OpenFabrics Libfabric: no
OpenFabrics Verbs: no
Portals4: no
Shared memory/copy in+copy out: yes
Shared memory/Linux CMA: yes
Shared memory/Linux KNEM: no
Shared memory/XPMEM: no
TCP: yes

I seem to be unable to disable CMA either with --without-cma or --with-cma=no.

Confirm that this is also the case with the Debian openmpi package. The configuration can be seen here: http://sources.debian.net/src/openmpi/2.1.0rc2-1/debian/rules/

(Ignore the 2.1.0rc2 version tag; it is 2.1.0)
