The ompi libfabric/Makefile.am to build the libmca_component_libfabric
lib was missing a recently added psmx_eq.c in the list of source
files for the psm provider.
Fixes#569
Signed-off-by: Howard Pritchard <howardp@lanl.gov>
When configured --with-devel-headers, there's now 2 "osd.h" header
files in libfabric (in different dirs). Automake's "install" target
didn't like this, and errored out.
Since embedding libfabric is a temporary measure, just avoid the
problem by not installing any libfabric headers.
Properly test for some dependent libraries; don't just assume
elsewhere in Open MPI's configury will find those libraries. Also
consolidate some CPPFLAGS and clarify some comments.
1. Ensure to override CFLAGS properly. Move the setting of CFLAGS outside the AM_CONDITIONAL so that Automake doesn't get confused (because CFLAGS is already set inside an AM_CONDITIONAL -- moving it outside the conditional ensure that this local CFLAGS override trumps all other CFLAGS overrides).
2. Only build libfabric on Linux. Add a little more configury to ensure that we only try to build libfabric on Linux.
3. Remove a dead/unused file
4. Fix typo in condition check
5. Use "false", not "/bin/false"
This commit represents the conversion of the usnic BTL from verbs to
libfabric.
For the moment, libfabric is embedded in Open MPI (currently in the
usnic BTL). This is because the libfabric API is still changing, and
also has not yet been released. Ultimately, this embedded copy of
libfabric will likely disappear and the usnic BTL will rely on an
external installation of libfabric.
New configure options:
* --with-libfabric: will cause configure to fail if libfabric support
cannot be built
* --without-libfabric: will prevent libfabric support from being built
* --with-libfabric=DIR: use an external libfabric installation
* --with-libfabric-libdir=LIBDIR: when paired with --with-libfabric=DIR,
use LIBDIR for the libfabric installation library dir
The --with-libnl3[-libdir] arguments are now gone.
