`configure' configures OpenJDK openjdk to adapt to many kinds of systems.

Usage: /Users/wdk/Code/openSourceCode/2_openJdk/openjdk/configure [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
                          [/usr/local]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

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

For better control, use the options below.

                          Equivalent to --host=TARGET --target=TARGET
                          --build=<current platform>, or the platform you
                          have provided if you have explicitly passed

Please be aware that, when cross-compiling, the OpenJDK configure script will
generally use 'target' where autoconf traditionally uses 'host'.

Also note that variables must be passed on the command line. Variables in the
environment will generally be ignored, unlike traditional autoconf scripts.
