2078 \`configure' configures this package to adapt to many kinds of systems.
2079
2080 Usage: $0 [OPTION]... [VAR=VALUE]...
2081
2082 To assign environment variables (e.g., CC, CFLAGS...), specify them as
2083 VAR=VALUE.  See below for descriptions of some of the useful variables.
2084
2085 Defaults for the options are specified in brackets.
2086
2087 Configuration:
2088   -h, --help              display this help and exit
2089       --help=short        display options specific to this package
2090       --help=recursive    display the short help of all the included packages
2091   -V, --version           display version information and exit
2092   -q, --quiet, --silent   do not print \`checking...' messages
2093       --cache-file=FILE   cache test results in FILE [disabled]
2094   -C, --config-cache      alias for \`--cache-file=config.cache'
2095   -n, --no-create         do not create output files
2096       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
2097
2098 Installation directories:
2099   --prefix=PREFIX         install architecture-independent files in PREFIX
2100                           [$ac_default_prefix]
2101   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
2102                           [PREFIX]
2103
2104 By default, \`make install' will install all the files in
2105 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2106 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2107 for instance \`--prefix=\$HOME'.
2108
2109 For better control, use the options below.
2110
2111 Fine tuning of the installation directories:
2112   --bindir=DIR            user executables [EPREFIX/bin]
2113   --sbindir=DIR           system admin executables [EPREFIX/sbin]
2114   --libexecdir=DIR        program executables [EPREFIX/libexec]
2115   --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]

2117   --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
2118   --libdir=DIR            object code libraries [EPREFIX/lib]
2119   --includedir=DIR        C header files [PREFIX/include]
2120   --oldincludedir=DIR     C header files for non-gcc [/usr/include]
2121   --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
2122   --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]

2135 Program names:

2137   --program-suffix=SUFFIX            append SUFFIX to installed program names
2138   --program-transform-name=PROGRAM   run sed PROGRAM on installed program names
2139
2140 System types:
2141   --build=BUILD     configure for building on BUILD [guessed]
2142   --host=HOST       cross-compile to build programs to run on HOST [BUILD]
2143   --target=TARGET   configure for building compilers for TARGET [HOST]

2151 Optional Features:
2152   --disable-option-checking  ignore unrecognized --enable/--with options
2153   --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
2154   --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
2155   --enable-maintainer-mode  enable make rules and dependencies not useful
2156                           (and sometimes confusing) to the casual installer
2157   --disable-largefile     omit support for large files
2158   --disable-dependency-tracking  speeds up one-time build
2159   --enable-dependency-tracking   do not reject slow dependency extractors
2160
2161 Some influential environment variables:
2162   CC          C compiler command
2163   CFLAGS      C compiler flags
2164   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
2165               nonstandard directory <lib dir>
2166   LIBS        libraries to pass to the linker, e.g. -l<library>
2167   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
2168               you have headers in a nonstandard directory <include dir>
2169   CPP         C preprocessor
2170
2171 Use these variables to override the choices made by `configure' or to help
2172 it to find libraries and programs with nonstandard names/locations.
