dnl Process this file with autoconf to produce a configure script.
dnl
dnl aclocal_cache.m4, included by sowing/confdb/aclocal.m4, fixes
dnl bugs in autoconf caching.
dnl
dnl This is a large configure script and it is important to keep it
dnl clearly organized. In addition, this script must coordinate with
dnl the other modules that can be used to construct MPICH, such as
dnl the communication device and the process manager. Each of these
dnl may have special features or limitations that other modules or
dnl this configure may need to take into account. To handle this, there
dnl are xx major steps in this configure script:
dnl
dnl 1. Identify major modules and source any prerequisite scripts
dnl 2. Determine compiler characteristics
dnl 3. Setup and configure the other modules
dnl 4. Determine MPI features and characteristics (such as datatype values)
dnl
dnl Each of these is described in more detail below.
dnl
dnl 1. Identify the modules (most are specified by
dnl --with-<modulename>=instance,
dnl for example, --with-pm=hydra or --with-device=ch3:nemesis).
dnl For each module, source the file mpichprereq if present (in the
dnl module's top-level directory). This
dnl must be a bourne (sh) shell script; it can access any of the variables
dnl in the configure script. In addition, there are a few variables that
dnl are defined and provided to allow the modules to communicate their
dnl needs or limitations to the other modules. These are:
dnl MPID_MAX_THREAD_LEVEL - thread level supported by device.
dnl if unset, is MPI_THREAD_FUNNELED
dnl MPID_NO_LONG_LONG - if yes, the device does not support the
dnl long long integer type
dnl MPID_NO_LONG_DOUBLE - if yes, the device does not support the
dnl long double type
dnl MPID_PM_NAMESERVER - if set, provides the name of the nameserver
dnl that the process manager supports.
dnl This name server will be used if the
dnl default name server is selected.
dnl MPID_NO_PM - If yes, the device does not require any
dnl PM implementation.
dnl MPID_MAX_PROCESSOR_NAME - The maximum number of character in a processor
dnl name. If not set, 128 will be used.
dnl MPID_MAX_ERROR_STRING - The maximum number of character in an error
dnl string. If not set, 1024 will be used.
dnl PM_REQUIRES_PMI - if set, provides the name of the PMI
dnl interface implementation. If not set,
dnl the "simple" PMI implementation is used.
dnl A process manager that needs a particular
dnl process manager should check that this is
dnl not set to an incompatible value.
dnl MPID_NO_SPAWN - if yes, the device does not support the
dnl dynamic process routines (spawn, connect
dnl attach, join, plus port and publish
dnl routines). The major effect of this
dnl is to let the test codes know that
dnl spawn is not implemented.
dnl MPID_NO_RMA - if yes, the device does not support the
dnl MPI RMA routines (MPI_Win_create and
dnl MPI_Put etc.). The major effect of this
dnl is to let the test codes know that
dnl RMA is not implemented.
dnl
dnl Note that the meanings of these variables are defined so that an
dnl undefined value gives the default. This makes it easy to expand
dnl the set of such variables, since only modules that need the new
dnl variable will need to be changed.
dnl
dnl 2. Determine compiler characteristics
dnl Here is where features of the compilers are determined, including
dnl support for shared libraries and sizes of the basic datatype types.
dnl
dnl 3. Setup and configure the other modules
dnl Before each module configure is executed, the script setup_<module>
dnl is run if present. This is a bourne (sh) shell script and may
dnl access configure variables. It should not make any changes to the
dnl compiler name or flags (e.g., do not add -D_XOPEN_SOURCE to CFLAGS here,
dnl because that may invalidate the determination of the compiler
dnl characteristics in the prior step).
dnl
dnl 4. Determine MPI features
dnl
dnl
dnl Special environment variables
dnl To let other scripts and in particular the configure in test/mpi
dnl know that they are being invoked from within the MPICH configure,
dnl the following environment variables are set and exported:
dnl FROM_MPICH
dnl MPICH_ENABLE_F77
dnl MPICH_ENABLE_FC
dnl MPICH_ENABLE_CXX
dnl
dnl Note that no executable statements are allowed (and any are silently
dnl dropped) before AC_INIT.

# We use an #include strategy here because all of the alternative strategies for
# quashing these variables have various drawbacks. The alternatives are listed
# here to avoid rediscovery of these problems by someone else in the future:
#
# 1) Strategy: Rewrite mpichconf.h.in with sed at autogen.sh time.
# Problem: Automatic remaking of config.status and friends will re-run
# autoheader and blow away our sed changes without an opportunity to
# patch the resulting file again.
# 2) Strategy: Add literal "#undef PACKAGE" lines to the AH_BOTTOM text.
# Problem: These lines get rewritten by config.status to be "#define" lines,
# so the intended quashing never actually occurs.
# 3) Strategy: Use AC_CONFIG_COMMANDS to run a sed rewrite command on
# mpichconf.h at config.status time.
# Problem: Causes mpichconf.h to always be rewritten, first by the normal
# config.status commands and then by sed. This can cause
# unnecessary remaking of object files since nearly every C source
# file includes this header (see the Autoconf Manual, "Automatic
# Remaking")
#
# The only other plausible strategy would seem to be rewriting config.status
# itself via AC_CONFIG_COMMANDS_POST, but that seems error prone. The best
# solution would be to stop all subconfigures from including config.h headers
# from other packages. Then all of this nonsense can be eliminated.
