./configure --with-platform=contrib/platform/$name will apply all patches
found in contrib/platform/$name.patches/ directory during "configure" phase.
It allows vendors to distribute not-accepted or vendor-specific patches as

The Intel 2016 compiler suite apparently only partially supports the
!GCC pragmas (prior versions either didn't support it at all, or our
existing configure test was sufficient to disqualify !GCC pragma
support when compiling with the Intel compiler).
With the existing configure test, the Intel 2016 compiler suite would
*pass* the test and therefore think that it could use !GCC as the
"ignore TKR" pragma. However, the "!GCC ATTRIBUTES NO_ARG_CHECK"
pragma doesn't work with scalar integers (although it seems to work
for the other types in this test).
This commit adds a scalar integer test to the ignore TKR pragma
configure test, which is enough to make the Intel 2016 compiler suite
fail with !GCC (this then allows configure to advance on to trying the
!DEC pragma, which *does* work properly with the Intel 2016 compiler
suite).
Thanks to Fabrice Roy for reporting the problem.

As of v15.7, the PGI Fortran compiler does not properly support how
Open MPI uses the "USE ... ONLY" Fortran syntax to include modules
with conflicting symbol definitions (interestingly, pgfortran only has
a problem with this when compiling with -g).
In short, OMPI uses "USE :: module_aaa, ONLY: foo" and "USE ::
module_bbb, ONLY: bar" to use modules aaa and bbb, even though they
contain conflicting definitions for some symbols. However, the use of
the ONLY clause should preclude the inclusion of the conflicting
symbols -- as the word implies, it should direct the compiler to
*only* use the symbols identified by the clause (i.e., foo and bar, in
this example).
This commit adds a configure test for this capability. If the
compiler fails to build a simple test that mimics this behavior, then
disable the mpi_f08 bindings.
Fixesopen-mpi/ompi#857
Only set OMPI_FORTRAN_BUILD_SIZEOF to 1 if $ompi_fortran_happy is also
1 (i.e., we're building the Fortran interface). This prevents
building [p]size_f.f90 and trying to compile it if there is no Fortran
compiler, for example.
This commit removes alpha asm support. No current processor
manufacturer makes chips compatible with DEC alpha and no
participating organization has alpha processors. This makes it
difficult to support alpha via assembly.
This doesn't mean Open MPI will no longer build/work on alpha
processors. It should continue to work with gcc's builtin sync
atomics.

Fortran uses objects (ompi_f08_mpi_comm_world, mpi_fortran_bottom,, ...) that are defined in C.
Some compilers have different requirements on how these objects should be aligned.
Smaller alignment in C can lead to several confusing warnings from the linker, so try to
find the alignment expected by Fortran compiler, and inform the C compiler.

their C bindings header file is generated.

@ggouaillardet is likely offline for the weekend, but master is broken

the liberty of revering this commit; I'm guessing Gilles will fixup
and re-commit next week.

This new MTL runs over PSM2 for Omni Path. PSM2 is a descendant of PSM
with changes to support more ranks and some MPI-3 features like mprobe.
PSM2 will only support Omni Path networks; PSM only supports True Scale.
Likewise, the existing PSM MTL will continue to be maintained for True
Scale, while the PSM2 MTL is developed and maintained for Omni Path.
* Add a few minor comments
* Rename $OMPI_WANT_FORTRAN_BINDINGS -> $OMPI_MIN_REQUIRED_FORTRAN_BINDINGS
* Minor whitespace cleanups
* Change an "if ..." to an AS_IF
Fujitsu compilers used with the GNU compatibility option (-Xg)
do not yet support all the gnu flags (e.g. -pedantic) and that can
cause the linker (and hence configure) crash.
Fujitsu compilers are identified by the __FUJITSU macro.
This adds a check at `make install` time to look for common symbols. It
attempts to ignore "Fortran-shaped" symbols by default. It also will
look in the source tree for any files named "common_sym_whitelist" and
will ignore any symbols listed in that file (one per line, comments
allowed).
See open-mpi/ompi#375 for more background.
== Short version
Do not export special variables into the environment (e.g., LIBS,
LDFLAGS, etc.) when invoking subdir configure scripts. This prevents
problems described in open-mpi/ompi#471.
== More detail
Exporing special env variables before invoking a subdir configure
script causes problems in some cases. E.g., in open-mpi/ompi#471,
when the user configures with `--with-hwloc=/path/to/hwloc`, and that
directory is *not* in a default linker search location will cause the
libevent subdir configuration to fail.
This happens because:
1. We'll pass LIBS="-L/path/to/hwloc/lib -lhwloc" to the libevent
configure script
1. Meaning: configure-generated executables will link successfully
1. But unless LD_LIBRARY_PATH (or some other
tell-the-linker-where-to-find-things mechanism) includes
/path/to/hwloc/lib, the executable can't run.
Specifically, the libevent "hey, does the compiler generate proper
executables?" check will fail, and configure will abort (because OMPI
needs libevent).
I checked the history: exporting these vars dates all the way back to
LAM/MPI. I can't think of a reason why we need to export these
variables -- AC_CONFIG_SUBDIRs doesn't do it; subdir configure scripts
should be orthogonal from the upper-layer configure script (and its
variables). So let's remove these export statements and see if
anything breaks.
Some versions of clang (at least >= 3.5 -- perhaps older versions,
too?) will *warn* about -finline-functions, but still allow it. This
is very annoying, so check for that warning, too.
Per discussion on devel
(http://www.open-mpi.org/community/lists/devel/2015/02/17030.php), and
per Autoconf 2.69 docs, use the recommended AC_SEARCH_LIBS instead of
AC_CHECK_LIB (e.g., for functions that appear in libc on some
platforms and in a specific library on other platforms).
Use of this configuration option can cause crashing, hanging, and
(worse) incorrect results when btl/sm, btl/scif, or btl/vader are
in use. We discussed this at the January 2015 developers meeting
and it was decided to remove the option entirely. This commit does
just that. All usage of OPAL_WANT_SMP_LOCKS has been removed.
Honestly, a bunch of this code could use similar treatment (i.e.,
AC_DEFUN a template that can be used for OPAL/ORTE/OMPI). However, I
don't quite have time for this today. Exercise left for the future reader...
The RPATH support added a @{libdir} token into
<package>_WRAPPER_EXTRA_LDFLAGS. However, these flags are also
substituted into the pkg-config data files, and they don't understand
the @{foo} notation. So convert @{libdir} into ${libdir}, which
pkg-config *does* understand.
Thanks to Christoph Junghans (@junghans) for notifying us of the issue.
Fixes#406.
It used to be important to get the latest config.sub and config.guess
from upstream because architectures were changing rapidly, and the GNU
Autotools released super-slowly.
However, architectures have not been changing nearly as fast -- the
versions of config.guess and config.sub that ship in the GNU Autotools
are fine. So let's stop getting upstream config.guess|sub from
upstream as part of "make dist".
per several reports on the devel ML, the opal_lifo test hangs
with intel icc 14.0.0.080 (aka 2013sp1) and intel icc 14.0.1.106 (aka 2013sp1u1).
/* older and more recents compilers work fine

Some systems have XRC symbols in their libibverbs libraries, but do
not have the appropriate XRC bits in their devel headers (cough cough
RHEL 6.5 libibverbs-rocee-*.x86-64.rpm cough cough).
So expand the XRC config checks to ensure that we can actually find
one of the XRC constants that we need to compile XRC code before
ruling that we can actually build XRC support.
Use the pkg-config related m4 functions to find out where
Cray's xpmem.h and libxpmem are located on a system.
With this commit, there is no longer any need to have to
explicitly indicate an xpmem install location on the configure
line, at least for Cray systems running CLE 4.X and 5.X.
Turns out the OPAL_FLAGS_UNIQ function was chopping
off multiple instances of --param when set in the
CFLAGS. This can happen when -mnative or other machine
target is specified as part of CFLAGS.
Thanks to QuesarVII for reporting this and supplying a patch.
Fixes#324
Before this commit we checked if the compiler supported compare-and-exchange
on 128-bit values. This turned out to be insufficient. This commit strengthens
the check to see if the processor supports the instruction (or built-in). This
check will not work when cross-compiling (will always disable the 128-bit
atomic) so overrides have been added for this case.
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.
Some versions of gcc require this flag to be set before the __sync
builtin atomic compare and swap will support 128-bit values. If the
flag is required this check adds the flag to the CFLAGS.
A 128-bit compare-and-swap will enable a better atomic lifo implementation
that uses the pointer + counter method to avoid ABA issues. This commit
adds configury to check for the instruction (cmpxchg16b) and adds an
implementation that uses the __int128 type available in C99.
Clean up the orte_check_alps.m4. There was a little of
unnecesary stuff for handling cle 5, since it wasn't actually
doing the right thing, which would be to use pkg-config to
find dependencies both for dynamic and static linking.
Decouple the searching for alps libs, etc. from cray pmi.
Switch the alps ess and alps odls components' config files
to use the ALPS m4 macro.
alps configury fixes
Improve a check for detecting CLE release.
Improve an error message.
Currently only shows whether opal_mca.m4 decides whether to build a
component or not. This will be helpful in debugging a remote user's
setup that somehow, mysteriously decides not to build a specific
component.
Change the CPPFLAGS to just -I$srcdir, and change the include file to
check to be just opal/libltdl/ltdl.h. Do this because the CPPFLAGS
are passed to the preprocessor, and the C program that is passed
through the preprocessor is basically:
#include <opal/libltdl/ltdl.h>
Using the proper -I covers both VPATH and non-VPATH cases.
