These two macros set the prefix for the OPAL and ORTE libraries, respectively. Specifically, the OPAL library will be named libPREFIXopen-pal.la and the ORTE library will be named libPREFIXopen-rte.la. These macros must be called, even if the prefix argument is empty. The intent is that Open MPI will call these macros with an empty prefix, but other projects (such as ORCM) will call these macros with a non-empty prefix. For example, ORCM libraries can be named liborcm-open-pal.la and liborcm-open-rte.la. This scheme is necessary to allow running Open MPI applications under systems that use their own versions of ORTE and OPAL. For example, when running MPI applications under ORTE, if the ORTE and OPAL libraries between OMPI and ORCM are not identical (which, because they are released at different times, are likely to be different), we need to ensure that the OMPI applications link against their ORTE and OPAL libraries, but the ORCM executables link against their ORTE and OPAL libraries.

# 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!

dist_opaldata_DATA = help-mpi-common-sm.txt
|
|
|
|
# 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.
