\`configure' configures OpenJDK jdk9 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/openjdk]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]

# Create a function/macro that takes a series of named arguments. The call is
# similar to AC_DEFUN, but the setup of the function looks like this:
# BASIC_DEFUN_NAMED([MYFUNC], [FOO *BAR], [$@], [
# ... do something
#   AC_MSG_NOTICE([Value of BAR is ARG_BAR])
# ])
# A star (*) in front of a named argument means that it is required and it's
# presence will be verified. To pass e.g. the first value as a normal indexed
# argument, use [m4_shift($@)] as the third argument instead of [$@]. These
# arguments are referenced in the function by their name prefixed by ARG_, e.g.
# "ARG_FOO".
#
# The generated function can be called like this:
# MYFUNC(FOO: [foo-val],
#     BAR: [
#         $ECHO hello world
#     ])
# Note that the argument value must start on the same line as the argument name.
#
# Argument 1: Name of the function to define
# Argument 2: List of legal named arguments, with a * prefix for required arguments
# Argument 3: Argument array to treat as named, typically $@
# Argument 4: The main function body


# Test if $1 is a valid argument to $3 (often is $JAVA passed as $3)
# If so, then append $1 to $2 \
# Also set JVM_ARG_OK to true/false depending on outcome.

# The basic idea is this:
# 1) You need an acceptable *) JDK to use as a Boot JDK
# 2) There are several ways to locate a JDK, that are mostly platform
#    dependent **)
# 3) You can have multiple JDKs installed
# 4) If possible, configure should try to dig out an acceptable JDK
#    automatically, without having to resort to command-line options
#
# *)  acceptable means e.g. JDK7 for building JDK8, a complete JDK (with
#     javac) and not a JRE, etc.
#
# **) On Windows we typically use a well-known path.
#     On MacOSX we typically use the tool java_home.
#     On Linux we typically find javac in the $PATH, and then follow a
#     chain of symlinks that often ends up in a real JDK.
#
# This leads to the code where we check in different ways to locate a
# JDK, and if one is found, check if it is acceptable. If not, we print
# our reasons for rejecting it (useful when debugging non-working
# configure situations) and continue checking the next one.
########################################################################

# Execute the check given as argument, and verify the result
# If the Boot JDK was previously found, do nothing
# $1 A command line (typically autoconf macro) to execute


# Test: Is bootjdk explicitly set by command line arguments?


# Test: Is $JAVA_HOME set?


# Test: Is there a java or javac in the PATH, which is a symlink to the JDK?


# Test: Is there a /usr/libexec/java_home? (Typically on MacOSX)
# $1: Argument to the java_home binary (optional)


# Test: On MacOS X, can we find a boot jdk using /usr/libexec/java_home?


# Look for a jdk in the given path. If there are multiple, try to select the newest.
# If found, set BOOT_JDK and BOOT_JDK_FOUND.
# $1 = Path to directory containing jdk installations.
# $2 = String to append to the found JDK directory to get the proper JDK home


# Call BOOTJDK_FIND_BEST_JDK_IN_DIRECTORY, but use the given
# environmental variable as base for where to look.
# $1 Name of an environmal variable, assumed to point to the Program Files directory.


# Test: Is there a JDK installed in default, well-known locations?


# Check that a command-line tool in the Boot JDK is correct
# $1 = name of variable to assign
# $2 = name of binary


###############################################################################

# We need a Boot JDK to bootstrap the build.
#





# BUILD_JDK: the location of the latest JDK that can run
#   on the host system and supports the target class file version
#   generated in this JDK build.  This variable should only be
#   used after the launchers are built.
#

# Execute the check given as argument, and verify the result.
# If the JDK was previously found, do nothing.
# $1 A command line (typically autoconf macro) to execute


# By default the BUILD_JDK is the JDK_OUTPUTDIR.  If the target architecture
# is different than the host system doing the build (e.g. cross-compilation),
# a special BUILD_JDK is built as part of the build process.  An external
# prebuilt BUILD_JDK can also be supplied.

The freetype library can now be build during the configure process.
Download the freetype sources and unpack them into an arbitrary directory:

wget http://download.savannah.gnu.org/releases/freetype/freetype-2.5.3.tar.gz
tar -xzf freetype-2.5.3.tar.gz

Then run configure with '--with-freetype-src=<freetype_src>'. This will
automatically build the freetype library into '<freetype_src>/lib64' for 64-bit
builds or into '<freetype_src>/lib32' for 32-bit builds.
Afterwards you can always use '--with-freetype-include=<freetype_src>/include'
and '--with-freetype-lib=<freetype_src>/lib32|64' for other builds.

Alternatively you can unpack the sources like this to use the default directory:

# Arguments:
#   VERSION:   The version string to check against the found version
#   IF_AT_LEAST:   block to run if the compiler is at least this version (>=)
#   IF_OLDER_THAN:   block to run if the compiler is older than this version (<)
#   PREFIX:   Optional variable prefix for compiler to compare version for (OPENJDK_BUILD_)




# Setup a number of variables describing how native output files are
# named on this platform/toolchain.


# Determine which toolchain type to use, and make sure it is valid for this
# platform. Setup various information about the selected toolchain.


# Before we start detecting the toolchain executables, we might need some
# special setup, e.g. additional paths etc.


# Restore path, etc


# Check if a compiler is of the toolchain type we expect, and save the version
# information from it. If the compiler does not match the expected type,
# this function will abort using AC_MSG_ERROR. If it matches, the version will
# be stored in CC_VERSION_NUMBER/CXX_VERSION_NUMBER (as a dotted number), and
# the full version string in CC_VERSION_STRING/CXX_VERSION_STRING.

# Try to locate the given C or C++ compiler in the path, or otherwise.
#
# $1 = compiler to test (CC or CXX)
# $2 = human readable name of compiler (C or C++)
# $3 = compiler name to search for


# Detect the core components of the toolchain, i.e. the compilers (CC and CXX),
# preprocessor (CPP and CXXCPP), the linker (LD), the assembler (AS) and the
# archiver (AR). Verify that the compilers are correct according to the
# toolchain type.


# Setup additional tools that is considered a part of the toolchain, but not the
# core part. Many of these are highly platform-specific and do not exist,
# and/or are not needed on all platforms.


# Setup the build tools (i.e, the compiler and linker used to build programs
# that should be run on the build platform, not the target platform, as a build
# helper). Since the non-cross-compile case uses the normal, target compilers
# for this, we can only do this after these have been setup.


# Do some additional checks on the detected tools.


# Setup the JTReg Regression Test Harness.
