\`configure' configures Valgrind 3.10.0 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]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --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/valgrind]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

  cat <<\_ACEOF

Program names:
  --program-prefix=PREFIX            prepend PREFIX to installed program names
  --program-suffix=SUFFIX            append SUFFIX to installed program names
  --program-transform-name=PROGRAM   run sed PROGRAM on installed program names

System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]

Optional Features:
  --disable-option-checking  ignore unrecognized --enable/--with options
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-maintainer-mode  enable make rules and dependencies not useful
			  (and sometimes confusing) to the casual installer
  --disable-dependency-tracking  speeds up one-time build
  --enable-dependency-tracking   do not reject slow dependency extractors
  --enable-only64bit      do a 64-bit only build
  --enable-only32bit      do a 32-bit only build
  --enable-inner          enables self-hosting
  --enable-tls            platform supports TLS

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-pagesize=        override detected page size (4, 16 or 64)
  --with-tmpdir=PATH      Specify path for temporary files
  --with-mpicc=           Specify name of MPI2-ised C compiler

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CPP         C preprocessor
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  AR          Archiver command
  CCAS        assembler compiler command (defaults to CC)
  CCASFLAGS   assembler compiler flags (defaults to CFLAGS)

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

# VGCONF_ARCH_PRI is the arch for the primary build target, eg. "amd64".  By
# default it's the same as ARCH_MAX.  But if, say, we do a build on an amd64
# machine, but --enable-only32bit has been requested, then ARCH_MAX (see
# above) will be "amd64" since that reflects the most that this cpu can do,
# but VGCONF_ARCH_PRI will be downgraded to "x86", since that reflects the
# arch corresponding to the primary build (VGCONF_PLATFORM_PRI_CAPS).  It is
# passed in to compilation of many C files via -VGA_$(VGCONF_ARCH_PRI) and
# -VGP_$(VGCONF_ARCH_PRI)_$(VGCONF_OS).


# VGCONF_ARCH_SEC is the arch for the secondary build target, eg. "x86".
# It is passed in to compilation of many C files via -VGA_$(VGCONF_ARCH_SEC)
# and -VGP_$(VGCONF_ARCH_SEC)_$(VGCONF_OS), if there is a secondary target.
# It is empty if there is no secondary target.


# VGCONF_PLATFORM_PRI_CAPS is the primary build target, eg. "AMD64_LINUX".
# The entire system, including regression and performance tests, will be
# built for this target.  The "_CAPS" indicates that the name is in capital
# letters, and it also uses '_' rather than '-' as a separator, because it's
# used to create various Makefile variables, which are all in caps by
# convention and cannot contain '-' characters.  This is in contrast to
# VGCONF_ARCH_PRI and VGCONF_OS which are not in caps.


# VGCONF_PLATFORM_SEC_CAPS is the secondary build target, if there is one.
# Valgrind and tools will also be built for this target, but not the
# regression or performance tests.
#
# By default, the primary arch is the same as the "max" arch, as commented
# above (at the definition of ARCH_MAX).  We may choose to downgrade it in
# the big case statement just below here, in the case where we're building
# on a 64 bit machine but have been requested only to do a 32 bit build.

# Platform variants?
#----------------------------------------------------------------------------

# Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
# But there are times where we need a bit more control.  The motivating
# and currently only case is Android: this is almost identical to
# {x86,arm,mips}-linux, but not quite.  So this introduces the concept of
# platform variant tags, which get passed in the compile as
# -DVGPV_<arch>_<os>_<variant> along with the main -DVGP_<arch>_<os> definition.
#
# In almost all cases, the <variant> bit is "vanilla".  But for Android
# it is "android" instead.
#
# Consequently (eg), plain arm-linux would build with
#
#   -DVGP_arm_linux -DVGPV_arm_linux_vanilla
#
# whilst an Android build would have
#
#   -DVGP_arm_linux -DVGPV_arm_linux_android
#
# Same for x86. The setup of the platform variant is pushed relatively far
# down this file in order that we can inspect any of the variables set above.

# In the normal case ..

# FIXME: do we also want to define automake variables

# VANILLA or ANDROID ?  This would be in the style of VGCONF_ARCHS_INCLUDE,
# VGCONF_PLATFORMS_INCLUDE and VGCONF_OS_IS above?  Could easily enough
# do that.  Problem is that we can't do and-ing in Makefile.am's, but
# that's what we'd need to do to use this, since what we'd want to write
# is something like
#
# VGCONF_PLATFORMS_INCLUDE_ARM_LINUX && VGCONF_PLATVARIANT_IS_ANDROID
#

# or the empty string if the compiler doesn't accept the flag. Note
# that checking is done against the warning flag itself, but the

/* Thanks to Mike Haertel and Jim Avera for this test.
   Here is a matrix of mmap possibilities:
	mmap private not fixed
	mmap private fixed at somewhere currently unmapped
	mmap private fixed at somewhere already mapped
	mmap shared not fixed
	mmap shared fixed at somewhere currently unmapped
	mmap shared fixed at somewhere already mapped
   For private mappings, we should verify that changes cannot be read()
   back from the file, nor mmap's back from the file at a different
   address.  (There have been systems where private was not correctly
   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.

   Grep wants private fixed already mapped.
   The main things grep needs to know about mmap are:
   * does it exist and is it safe to write into the mmap'd area
   * how to use it (BSD variants)  */

#----------------------------------------------------------------------------
# Other library checks
#----------------------------------------------------------------------------
# There now follow some tests for Boost, and OpenMP.  These
# tests are present because Drd has some regression tests that use
# these packages.  All regression test programs all compiled only
# for the primary target.  And so it is important that the configure
# checks that follow, use the correct -m32 or -m64 flag for the
# primary target (called $mflag_primary).  Otherwise, we can end up
# in a situation (eg) where, on amd64-linux, the test for Boost checks
# for usable 64-bit Boost facilities, but because we are doing a 32-bit
# only build (meaning, the primary target is x86-linux), the build
# of the regtest programs that use Boost fails, because they are
# build as 32-bit (IN THIS EXAMPLE).
#
# Hence: ALWAYS USE $mflag_primary FOR CONFIGURE TESTS FOR FACILITIES
# NEEDED BY THE REGRESSION TEST PROGRAMS.


# Check whether the boost library 1.35 or later has been installed.
# The Boost.Threads library has undergone a major rewrite in version 1.35.0.

# It is not useful on other systems.  If it contains results you don't
# want to keep, you may remove or edit it.

# So, we kill variables containing newlines.
