# 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_portals.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_portals.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. Libtool sorts this all
# out and it all works out in the end.
#
# Note that building this common component statically and linking
# against other dynamic components is *not* supported!

EXTRA_DIST = common_portals_crayxt3.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.
