## Initialize configure.
##
AC_PREREQ([2.69])
## AC_INIT takes the name of the package, the version number, and an
## email address to report bugs. AC_CONFIG_SRCDIR takes a unique file
## as its argument.
##
## NOTE: Do not forget to change the version number here when we do a
## release!!!
##
AC_INIT([HDF5], [1.13.0-7], [[email protected]])
AC_CONFIG_SRCDIR([src/H5.c])
AC_CONFIG_HEADERS([src/H5config.h])
AC_CONFIG_AUX_DIR([bin])
AC_CONFIG_MACRO_DIR([m4])
## AM_INIT_AUTOMAKE takes a list of options that should be applied to
## every Makefile.am when automake is run.
AM_INIT_AUTOMAKE([foreign subdir-objects])
m4_ifdef([AM_SILENT_RULES], [AM_SILENT_RULES([yes])]) # use silent rules where available - automake 1.11
## AM_MAINTAINER_MODE determines the behavior of "rebuild rules" that contain
## dependencies for Makefile.in files, configure, src/H5config.h, etc. If
## AM_MAINTAINER_MODE is enabled, these files will be rebuilt if out of date.
## When disabled, the autotools build files can get out of sync and the build
## system will not complain or try to regenerate downstream files.
##
## The AM_MAINTAINER_MODE macro also determines whether the
## --(enable|disable)-maintainer-mode configure option is available. When the
## macro is present, with or without a parameter, the option will be added
## to the generated configure script.
##
## In summary:
##
## AM_MAINTAINER_MODE([enable])
## - Build dependencies ON by default
## - Configure option exists
##
## AM_MAINTAINER_MODE([disable])
## - Build dependencies OFF by default
## - Configure option exists
##
## AM_MAINTAINER_MODE
## - Build dependencies OFF by default
## - Configure option exists
##
## No AM_MAINTAINER_MODE macro
## - Build dependencies ON by default
## - No configure option to control build dependencies
##
## The biggest concern for us is that version control systems like git
## usually don't preserve dependencies between timestamps, so the build
## system will often think that upstream build files like Makefile.am are
## dirty and that rebuilding needs to occur when it doesn't. This is a problem
## in release branches where we provide the autotools-generated files. Users
## who don't have autoconf, automake, etc. will then have difficulty building
## release branches checked out from git.
##
## By default, maintainer mode is enabled in development branches and disabled
## in release branches.

## The solution on Cygwin is not to record execution time for tests.

## Note: This is still true as of Cygwin 1.7.32 (Aug 2014) on both 32-
## and 64-bit platforms. Given how long this has been true, it seems
## unlikely to change, but we should probably re-test this periodically.

## The following variables are used to distinguish between building a
## serial and parallel library.
##
## HAVE_PARALLEL -- defined in H5config.h if we are building
## a parallel library even if configure wasn't
## able to find some header file or library that
## might be required. This is defined if the
## user explicitly states
## that a parallel library is being built by supplying
## the `--enable-parallel' configure switch.
##
## PARALLEL -- This variable is set to a non-null value if
## we're building a parallel version of the library.
##
## RUNSERIAL -- This is a command which will be prepended to
## the executable name to run the executable using
## a single process. For serial versions of the
## library this will normally be empty. For parallel
## versions it might be something like `mpiexec -n 1'.
## The value of this variable is substituted in *.in
## files.
##
## RUNPARALLEL -- This is a command which will be prepended to
## the executable name to run the executable on
## multiple processors. For the serial library the
## value will normally be the empty string. For
## parallel library it should be something like
## "mpiexec -n \$\${NPROCS:=6}" where NPROCS will
## eventually contain the number of processors on which
## to run the executable (the double dollarsigns are to
## protect the expansion until make executes the
## command). The value of this variable is
## substituted in *.in files.
