AM_INIT_AUTOMAKE, instead of the deprecated version. * Work around dumbness in modern AC_INIT that requires the version number to be set at autoconf time (instead of at configure time, as it was before). Set the version number, minus the subversion r number, at autoconf time. Override the internal variables to include the r number (if needed) at configure time. Basically, the right thing should always happen. The only place it might not is the version reported as part of configure --help will not have an r number. * Since AM_INIT_AUTOMAKE taks a list of options, no need to specify them in all the Makefile.am files. * Addes support for subdir-objects, meaning that object files are put in the directory containing source files, even if the Makefile.am is in another directory. This should start making it feasible to reduce the number of Makefile.am files we have in the tree, which will greatly reduce the time to run autogen and configure. This commit was SVN r7211.

# 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.
