# A word of explanation...
|
|
#
|
|
# This library is linked against various MCA components because all
|
|
# shared-memory based components (e.g., mpool, ptl, etc.) need to
|
|
# share some common code and data. There's two cases:
|
|
#
|
|
# 1. libmca_common_sm.la is a shared library. By linking that shared
|
|
# library to all components that need it, the OS linker will
|
|
# automatically load it into the process as necessary, and there will
|
|
# only be one copy (i.e., all the components will share *one* copy of
|
|
# the code and data).
|
|
#
|
|
# 2. libmca_common_sm.la is a static library. In this case, it will
|
|
# be rolled up into the top-level libmpi.la. It will also be rolled
|
|
# into each component, but then the component will also be rolled up
|
|
# into the upper-level libmpi.la. Linkers universally know how to
|
|
# "figure this out" so that we end up with only one copy of the code
|
|
# and data.
|
|
#
|
|
# Note that building this common component statically and linking
|
|
# against other dynamic components is *not* supported!
|
|
|
|
# Use the top-level Makefile.options
|
|
|
|
|
|
|
|
# Header files
|
|
|
|
headers = \
|
|
common_sm_mmap.h
|
|
|
|
# Source files
|
|
|
|
sources = \
|
|
common_sm_mmap.c
|
|
|
|
# As per above, we'll either have an installable or noinst result.
|
|
# The installable one should follow the same MCA prefix naming rules
|
|
# (i.e., libmca_<type>_<name>.la). The noinst one can be named
|
|
# whatever it wants, although libmca_<type>_<name>_noinst.la is
|
|
# recommended.
|
|
|
|
# To simplify components that link to this library, we will *always*
|
|
# have an output libtool library named libmca_<type>_<name>.la -- even
|
|
# for case 2) described above (i.e., so there's no conditional logic
|
|
# necessary in component Makefile.am's that link to this library).
|
|
# Hence, if we're creating a noinst version of this library (i.e.,
|
|
# case 2), we sym link it to the libmca_<type>_<name>.la name
|
|
# (libtool will do the Right Things under the covers). See the
|
|
# all-local and clean-local rules, below, for how this is effected.
