## ## Copyright (C) by Argonne National Laboratory ## See COPYRIGHT in top-level directory ## AC_PREREQ([2.69]) 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-=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_ 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, e.g. configure in hydra and romio, 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 dnl Note that no executable statements are allowed (and any are silently dnl dropped) before AC_INIT. m4_define([MPICH_CONFIGURE], 1) m4_include([maint/version.m4]) dnl 2nd arg is intentionally underquoted AC_INIT([MPICH], MPICH_VERSION_m4, [discuss@mpich.org], [mpich], [http://www.mpich.org/]) if test "x$prefix" != "xNONE" && test -d "$prefix"; then if test "x`(cd \"$prefix\"; echo \"$PWD\")`" = "x`(cd \"$srcdir\"; echo \"$PWD\")`" ||\ test "x`(cd \"$prefix\"; echo \"$PWD\")`" = "x$PWD" ; then AC_MSG_ERROR([The install directory (--prefix=) cannot be the same as the build or src directory.]) fi fi CONFIGURE_ARGS_CLEAN=`echo $* | tr '"' ' '` AC_SUBST(CONFIGURE_ARGS_CLEAN) # these values come from the m4_include above MPICH_VERSION=MPICH_VERSION_m4 AC_SUBST([MPICH_VERSION]) MPICH_RELEASE_DATE="MPICH_RELEASE_DATE_m4" AC_SUBST([MPICH_RELEASE_DATE]) libmpi_so_version="libmpi_so_version_m4" AC_SUBST([libmpi_so_version]) if test -z "$MPICH_VERSION" ; then AC_MSG_ERROR([MPICH_VERSION is empty, check maint/version.m4 for errors]) fi # Produce a numeric version assuming the following format: # Version: [MAJ].[MIN].[REV][EXT][EXT_NUMBER] # Example: 1.0.7rc1 has # MAJ = 1 # MIN = 0 # REV = 7 # EXT = rc # EXT_NUMBER = 1 # # Converting to numeric version will convert EXT to a format number: # ALPHA (a) = 0 # BETA (b) = 1 # RC (rc) = 2 # PATCH (p) = 3 # Regular releases are treated as patch 0 # # Numeric version will have 1 digit for MAJ, 2 digits for MIN, # 2 digits for REV, 1 digit for EXT and 2 digits for EXT_NUMBER. changequote(<<,>>) V1=`expr $MPICH_VERSION : '\([0-9]*\)\.[0-9]*\.*[0-9]*[a-zA-Z]*[0-9]*'` V2=`expr $MPICH_VERSION : '[0-9]*\.\([0-9]*\)\.*[0-9]*[a-zA-Z]*[0-9]*'` V3=`expr $MPICH_VERSION : '[0-9]*\.[0-9]*\.*\([0-9]*\)[a-zA-Z]*[0-9]*'` V4=`expr $MPICH_VERSION : '[0-9]*\.[0-9]*\.*[0-9]*\([a-zA-Z]*\)[0-9]*'` V5=`expr $MPICH_VERSION : '[0-9]*\.[0-9]*\.*[0-9]*[a-zA-Z]*\([0-9]*\)'` changequote([,]) if test "$V2" -le 9 ; then V2=0$V2 ; fi if test "$V3" = "" ; then V3=0; fi if test "$V3" -le 9 ; then V3=0$V3 ; fi if test "$V4" = "a" ; then V4=0 elif test "$V4" = "b" ; then V4=1 elif test "$V4" = "rc" ; then V4=2 elif test "$V4" = "" ; then V4=3 V5=0 elif test "$V4" = "p" ; then V4=3 fi if test "$V5" -le 9 ; then V5=0$V5 ; fi MPICH_NUMVERSION=`expr $V1$V2$V3$V4$V5 + 0` AC_SUBST(MPICH_NUMVERSION) AC_ARG_WITH(custom-version-string, AS_HELP_STRING([--with-custom-version-string], [Adds a user-specified value to the output of the mpichversion executable]),,with_custom_version_string="") MPICH_CUSTOM_STRING=$with_custom_version_string AC_SUBST(MPICH_CUSTOM_STRING) # ABIVERSION is the name used by simplemake, so we reassign the # libmpi_so_version number to it ABIVERSION=${libmpi_so_version} export ABIVERSION export libmpi_so_version AC_SUBST(ABIVERSION) # Print out the configure options CONFIGURE_ARGUMENTS="$ac_configure_args" AC_SUBST(CONFIGURE_ARGUMENTS) if test -n "$ac_configure_args" ; then echo "Configuring MPICH version $MPICH_VERSION with $ac_configure_args" else echo "Configuring MPICH version $MPICH_VERSION" fi # Add the information on the system: echo "Running on system: `uname -a`" dnl Definitions will be placed in this file rather than in the DEFS variable AC_CONFIG_HEADERS([src/include/mpichconf.h]) AH_TOP([/* * Copyright (C) by Argonne National Laboratory * See COPYRIGHT in top-level directory */ #ifndef MPICHCONF_H_INCLUDED #define MPICHCONF_H_INCLUDED ]) # We use an #include strategy here because all of the alternative strategies for # quashing these variables have various drawbacks.
