\`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 \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:安装内部使用的参数
  --bindir=DIR           user executables [EPREFIX/bin]
  --sbindir=DIR          system admin executables [EPREFIX/sbin]
  --libexecdir=DIR       program executables [EPREFIX/libexec]
  --sysconfdir=DIR       read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR   modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR    modifiable single-machine data [PREFIX/var]
  --libdir=DIR           object code libraries [EPREFIX/lib]
  --includedir=DIR       C header files [PREFIX/include]
  --oldincludedir=DIR    C header files for non-gcc [/usr/include]
  --datarootdir=DIR      read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR          read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR          info documentation [DATAROOTDIR/info]
  --localedir=DIR        locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR           man documentation [DATAROOTDIR/man]
  --docdir=DIR           documentation root [DATAROOTDIR/doc/PACKAGE]
  --htmldir=DIR          html documentation [DOCDIR]
  --dvidir=DIR           dvi documentation [DOCDIR]
  --pdfdir=DIR           pdf documentation [DOCDIR]
  --psdir=DIR            ps documentation [DOCDIR]
_ACEOF
  cat <<\_ACEOF
Program names:
  --program-prefix=PREFIX            prepend PREFIX to installed program names
  --program-suffix=SUFFIX            append SUFFIX to installed program names
  --program-transform-name=PROGRAM   run sed PROGRAM on installed program names
X features:
  --x-includes=DIR    X include files are in DIR
  --x-libraries=DIR   X library files are in DIR
System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]
_ACEOF
fi
if test -n "$ac_init_help"; then
  cat <<\_ACEOF
Optional Features:
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-shared[=PKGS]  build shared libraries [default=yes]
生成动态库.so,默认是生成的,但有些不能生成,需要在./configure时加上该选项
        ./configure --enable-shared
再make install时加上生成动态库
        make install -shared  或者  make install -shared-so
  --enable-static[=PKGS]  build static libraries [default=yes]
  --enable-fast-install[=PKGS]
                          optimize for fast installation [default=yes]
  --disable-dependency-tracking  speeds up one-time build
  --enable-dependency-tracking   do not reject slow dependency extractors
  --disable-libtool-lock  avoid locking (might break parallel builds)
  --enable-pch                 enable precompiled header (default is disabled)
  --enable-gcov                enable option for gcov coverage testing (default is disabled)
  --disable-werror            disable -Werror flag (default is enabled for non-release)
  --disable-optimization      disable optimization flags (default is enabled)
Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
  --with-pic              try to use only PIC/non-PIC objects [default=use
                          both]
  --with-tags[=TAGS]      include additional configurations [automatic]
  --with-binutils=dir  Path to binutils installation to use
  --with-gcc=dir  Path to GCC installation to use
  --with-kernel-support        Use 2.6 kernel (no kernel source tree required)
      2.6内核进行一些与内核相关的测试工具时需要内核的支持,如oprofile工具            
  --with-linux=dir             Path to Linux source tree
     指明要使用的内核树    
  --with-module-dir=dir        Path to module installation directory
  --with-java=java-home        Path to Java home directory
  --with-extra-includes=DIR    add extra include paths
     指明要链接的外部的目录    
  --with-extra-libs=DIR        add extra library paths
     指明要链接的外部的库     
  --with-x                use the X Window System
  --with-qt-dir           where the root of Qt is installed
  --with-qt-includes      where the Qt includes are.
  --with-qt-libraries     where the Qt library is installed.
  --with-target=cell-be   Check BFD support for Cell Broadband Engine SPU profiling
Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L if you have libraries in a
              nonstandard directory
  LIBS        libraries to pass to the linker, e.g. -l
  CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I if
              you have headers in a nonstandard directory
  CPP         C preprocessor
  CXX         C++ compiler command
  CXXFLAGS    C++ compiler flags
  CXXCPP      C++ preprocessor
  F77         Fortran 77 compiler command
  FFLAGS      Fortran 77 compiler flags
  XMKMF       Path to xmkmf, Makefile generator for X Window System
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

实际上configure文件是个Shell文件,其中定义了那些参数一般用 --help 选项来说明,因此如果想要查看其中某个选项的具体动作,不如直接查看configure文件本身更直接一些。 :)
