\`configure' configures this package 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]

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-manager=ARG    memory managers: no, builtin, memwatch, dmalloc,

                          gcollect, bcheck (defaults to builtin)

  --enable-packetver=ARG  Sets the PACKETVER define of the map-server. (see

                          src/map/clif.h)

  --enable-debug[=ARG]    Compiles extra debug code. (disabled by default)

                          (available options: yes, no, gdb)

  --enable-buildbot[=ARG] (available options: yes, no)

  --enable-rdtsc          Uses rdtsc as timing source (disabled by default)

                          Enable it when you've timing issues. (For example:

                          in conjunction with XEN or Other Virtualization

                          mechanisms) Note: Please ensure that you've disabled

                          dynamic CPU-Frequencys, such as power saving

                          options. (On the most modern Dedicated Servers

                          cpufreq is preconfigured, see your distribution's

                          manual how to disable it)

  --enable-profiler=ARG   Profilers: no, gprof (disabled by default)

  --disable-64bit         Enforce 32bit output on x86_64 systems.

  --enable-lto            Enables or Disables Linktime Code Optimization (LTO

                          is enabled by default)

Optional Packages:

  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]

  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)

  --with-mysql[=ARG]      optionally specify the path to the mysql_config

                          executable

  --with-MYSQL_CFLAGS=ARG specify MYSQL_CFLAGS manually (instead of using

                          "mysql_config --include")

  --with-MYSQL_LIBS=ARG   specify MYSQL_LIBS manually (instead of using

                          "mysql_config --libs")

  --with-pcre[=ARG]       use PCRE library, optionally specify the full path

                          of pcre installation directory (by default pcre is

                          used if found)

  --with-zlib=DIR         root directory path of zlib installation (defaults

                          to /usr/local or /usr if not found in /usr/local).

                          Assumes that the header files are in DIR/include and

                          the library files are in DIR/lib

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

Use these variables to override the choices made by `configure' or to help

it to find libraries and programs with nonstandard names/locations.

Report bugs to the package provider.
