Folks,
i made https://github.com/open-mpi/ompi/pull/1376 to fix this issue
note it also revert the changes previously introduced in
ompi/runtime/ompi_mpi_init.c
Cheers,
Gilles

Jeff,
this commit only fixes MPI_Init() and not the openib btl.
As Ralph pointed previously, there is still an abstraction violation
in MPI_Init() and it is now "under control"
as it was before.
Regarding this issue (opal_memory_linux_malloc_set_alignment), i will
extend the memory mca since
yet an other abstraction violation does not seem necessary here.
Cheers,
Gilles

FWIW, I'm unable to replicate the error on master.
Did this commit not fix it for you?
https://github.com/open-mpi/ompi/commit/7de01b347cd13544439b4eae86607a535c32489c
If it didn't, then we might as well revert that commit and PR 1351
until it's fixed properly.

Probably should - looks like this may take more thought and probably
will be handled in
discussions next week

Hi Folks,
Should we revert PR 1351 till there is a fix?

FWIW: I wouldn’t have seen that because I don’t have IB on my system.

So this seems to be still broken.
mca_btl_openib.so: undefined symbol:

It is very easy to reproduce - configure with:
enable_mem_debug=no
enable_mem_profile=no
enable_memchecker=no
with_memory_manager=no
I’m not sure which of those is required. However, your assertion
is incorrect. The
person who introduced the original violation went to great lengths
to ensure it didn’t
create a problem if the referenced component was not built. I’m not
saying it was a good
thing to do, but we spent a lot of time discussing it and figuring
out how to do it without
causing the problem.
So whatever was done missed those precautions and introduced this
symbol regardless
of the configuration.

Ralph,
this is being discussed at
https://github.com/open-mpi/ompi/pull/1351
btw, how do you get this warning ? i do not see it.
fwiw, the abstraction violation was kind of already here, so i am
surprised it pops
up now only
Cheers,
Gilles

Looks like someone broke the master build on Linux:
../../../ompi/.libs/libmpi.so: undefined reference to
`opal_memory_linux_malloc_init_hook'
I suspect it was a hard-coded reference to some component’s
variable?
