#
# (C) 2006 by Argonne National Laboratory.
# See COPYRIGHT in top-level directory.
#
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 MPICH2, 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=mpd or --with-device=ch3:nemesis).
dnl For each module, source the file mpich2prereq 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_NO_PMI - If yes, the device does not require any
dnl PMI implementation.
dnl EXTRA_STATUS_DECL - Any extra declarations that the device
dnl needs added to the definition of MPI_Status.
dnl MPID_MAX_PROCESSOR_NAME - The maximum number of character in a processor
dnl name. If not set, 128 will be used.
dnl PMI_REQUIRES_READABLE_TOKENS - if yes, define the C-preprocessor
dnl value USE_HUMAN_READABLE_TOKENS, which is
dnl used in src/include/mpimem.h to define token
dnl separators used in src/util/mem/argstr.c
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 MPICH2 configure,
dnl the following environment variables are set and exported:
dnl FROM_MPICH2
dnl MPICH2_ENABLE_F77
dnl MPICH2_ENABLE_FC
dnl MPICH2_ENABLE_CXX
dnl
dnl The file name here refers to a file in the source being configured
dnl In later versions of autoconf, the binding of AC_INIT changed (!!!)
dnl The original version was AC_INIT(a source file)
dnl The later version is AC_INIT(package,version,[bug-report],[tarname])
dnl Here we use the original version
dnl AC_INIT(src/include/mpiimpl.h)
dnl
dnl Note that no executable statements are allowed (and any are silently
dnl dropped) before AC_INIT.
dnl
dnl AC_INIT requires an explicit version number
dnl Args are package name, version, bug report, and tar file name
dnl All must be literals
dnl Note that AC_PACKAGE_STRING is not a command but must be defined(!)
dnl Unfortunately, setting the PACKAGE names is not compatible with
dnl AC_CONFIG_SUBDIRS, since the resulting values in the generated
dnl conf file will not be consistent.
dnl define([AC_PACKAGE_STRING],[MPICH2 1.0.6])
dnl AC_INIT(mpich2,1.0.6,mpich2-maint@mcs.anl.gov,mpich2-1.0.6)
dnl Use the oldstyle AC_INIT instead
AC_INIT(src/include/mpichconf.h.in)
