'configure' configures R 4.6.0 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print 'checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for '--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or '..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, 'make install' will install all the files in
'$ac_default_prefix/bin', '$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than '$ac_default_prefix' using '--prefix',
for instance '--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]

  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/R]
  --htmldir=DIR           html documentation [DOCDIR]

### ** DLL stuff.

## We need to determine the following:
##
## MAIN_LD, MAIN_LDFLAGS
##   command and flags for loading the main binary so that it will load
##   shared objects (DLLs) at runtime, also for profiling.
## CPICFLAGS, CXXPICFLAGS, FPICFLAGS
##   flags for compiling C, C++, and Fortran library code.
## SHLIB_LD, SHLIB_LDFLAGS
##   command and flags for creating DLLs (which contain object files
##   from a C or Fortran compiler).
## DYLIB_LD, DYLIB_LDFLAGS
##   ditto for dynamic libraries (where different.)
## SHLIB_CXXLD, SHLIB_CXXLDFLAGS
##   command and flags for creating DLLs which contain object files from
##   a C++ compiler.  According to Autoconf, the C++ compiler/linker
##   must be used for linking in this case (since special C++-ish things
##   need to happen at link time like calling global constructors,
##   instantiating templates, enabling exception support, etc.).
##
## The procedure is as follows.
##
## * We use applicable values from imake in case its CC is ours.
## * Irrespective of that, we think we know what to do with GNU tools
##   (GNU C, Fortran, and C++ compilers).
## * Then, use platform specific overrides.
## * As a final safeguard, values from the environment (as specified in
##   one of the configuration files or at the configure command line)
##   override anything we figure out in the case of compiler flags; for
##   linker flags (*LDFLAGS), environment settings override our results
##   if the corresponding *LD variable was set, and add otherwise.
##
## NOTE: We do not provide defaults for the *LDFLAGS, taking a defensive
## approach.  In case we cannot figure out {MAIN,SHLIB}_LDFLAGS and the
## user did not provide defaults, an error results.  A warning is given
## if nothing was obtained for SHLIB_CXXLDFLAGS.
##
## Note also that some systems (formerly AIX) do not allow for unresolved
## symbols at link time.  For such systems, we link against -lm (in case
## it exists) when building a shlib module via SHLIB_LIBADD.

### OpenMP.

## The basic checking is performed via AC_OPENMP added in Autoconf 2.62,
## which we already called for determining the appropriate flags for the
## C, C++, Fortran compiler/linker.  Note that this gives
## variables OPENMP_CFLAGS etc., which are meant to be used for *both*
## compiling and linking.  So we can really only used them provided that
## we use the respective compilers for linking as well (or we need a
## different mechanism for determining what is needed).
##
## For compiling R itself, we use MAIN_LD and DYLIB_LD for linking, both
## defaulting to CC.  Hence:
##
##    If both MAIN_LD and DYLIB_LD were not specified by the user and
##    equal CC and this was determined to support OpenMP, then we (try
##    to) provide OpenMP support by adding OPENMP_CFLAGS to the linker
##    flags and OPENMP_CFLAGS and OPENMP_FFLAGS to the C and Fortran
##    compiler flags, and defining HAVE_OPENMP.
##
## (The fixed-form Fortran compiler is never used for linking by default.)

## For compiling package code, we use SHLIB_FCLD, SHLIB_CXXLD or
## SHLIB_LD for linking, depending on whether the package contains
## free-form Fortran code, C++ (or ObjC) code, or "just" C and fixed-form Fortran.
## However, we (currently) do not conditionalize compilation flags.  So
## the only "safe" thing we can do for now is:
##
##    If none of SHLIB_LD, SHLIB_CXXLD and SHLIB_FCLD were specified by
##    the user and equal CC, CXX and FC, respectively, and these were
##    determined to support OpenMP, the we try to provide OpenMP support
##    for packages by adding OPENMP_FCFLAGS, OPENMP_CXXFLAGS and
##    OPENMP_CFLAGS to the respective linker flags, and add the OPENMP
##    flags to all (C, C++ and Fortran) compiler flags.

  ## We have two ways of doing that:
  ## * Recording whether '-Wl,' is needed for the C or C++ compilers,
  ##   and getting this info into the TCLTK_LIBS make variable ... mess!
  ## * Protecting all entries in TCLTK_LIBS that do not start with '-l'
  ##   or '-L' with '-Wl,' (hoping that all compilers understand this).

	mmap shared not fixed
	mmap shared fixed at somewhere currently unmapped

   implemented like the infamous i386 svr4.0, and systems where the
   VM page cache was not coherent with the file system buffer cache
   like early versions of FreeBSD and possibly contemporary NetBSD.)
   For shared mappings, we should conversely verify that changes get
   propagated back to all the places they're supposed to be.  */
