squid的configure 配置选项

`configure' configures Squid Web Proxy 3.2.3 to adapt to many kinds of systems.


Usage: ./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/squid]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]


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


For better control, use the options below.

  --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


System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]


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-maintainer-mode  enable make rules and dependencies not useful
 (and sometimes confusing) to the casual installer
  --disable-dependency-tracking  speeds up one-time build
  --enable-dependency-tracking   do not reject slow dependency extractors
  --disable-strict-error-checking
                          By default squid is compiled with all possible
                          static compiler error-checks enabled. This flag
                          disables the behavior
  --disable-loadable-modules
                          do not support loadable modules
  --enable-shared[=PKGS]  build shared libraries [default=yes]
  --enable-static[=PKGS]  build static libraries [default=yes]
  --enable-fast-install[=PKGS]
                          optimize for fast installation [default=yes]
  --disable-libtool-lock  avoid locking (might break parallel builds)
  --enable-ltdl-install   install libltdl
  --enable-build-info="build info string"
                          Add an additional string in the output of "squid
                          -v". Default is not to add anything. If the string
                          is not specified, tries to determine nick and
                          revision number of the current bazaar branch
  --disable-optimizations Do not compile Squid with compiler optimizations
                          enabled. Optimization is good for production builds,
                          but not good for debugging. During development, use
                          --disable-optimizations to reduce compilation times
                          and allow easier debugging. This option implies
                          --disable-inline
  --disable-inline        Do not compile trivial methods as inline. Squid is
                          coded with much of the code able to be inlined.
                          Inlining is good for production builds, but not good
                          for development. During development, use
                          --disable-inline to reduce compilation times and
                          allow incremental builds to be quick. For production
                          builds, or load tests, use --enable-inline to have
                          squid make all trivial methods inlinable by the
                          compiler.
  --enable-debug-cbdata   Provide some debug information in cbdata
  --enable-xmalloc-statistics
                          Show malloc statistics in status page
  --enable-disk-io="list of modules"
                          Build support for the list of disk I/O modules. Set
                          without a value or omitted, all available modules

                          available modules, or Programmers Guide section on
                          DiskIO for details on how to build your custom disk
                          module
  --enable-storeio="list of modules"
                          Build support for the list of store I/O modules. The
                          default is only to build the "ufs" module. See
                          src/fs for a list of available modules, or
                          Programmers Guide section <not yet written> for
                          details on how to build your custom store module
  --enable-removal-policies="list of policies"
                          Build support for the list of removal policies. The
                          default is only to build the "lru" module. See
                          src/repl for a list of available modules, or
                          Programmers Guide section 9.9 for details on how to
                          build your custom policy

  --enable-leakfinder     Enable Leak Finding code. Enabling this alone does
                          nothing; you also have to modify the source code to
                          use the leak finding functions. Probably Useful for
                          hackers only.
  --enable-follow-x-forwarded-for
                          Enable support for following the X-Forwarded-For
                          HTTP header to try to find the IP address of the

  --enable-auth-basic="list of helpers"
                          Enable the basic authentication scheme, and build
                          the specified helpers. Not providing an explicit
                          list of helpers will attempt build of all possible
                          helpers. Default is to do so. To disable the basic
                          authentication scheme, use --disable-auth-basic. To
                          enable but build no helpers, specify "none". To see
                          available helpers, see the helpers/basic_auth
                          directory.

                          possible helpers. Default is to do so. To disable
                          the Negotiate authentication scheme, use
                          --disable-auth-negotiate. To enable but build no
                          helpers, specify "none". To see available helpers,
                          see the helpers/negotiate_auth directory.
  --enable-auth-digest="list of helpers"
                          Enable the Digest authentication scheme, and build
                          the specified helpers. Not providing an explicit
                          list of helpers will attempt build of all possible

                          This option selects which logging daemon helpers to
                          build and install as part of the normal build
                          process For a list of available helpers see the
                          helpers/log_daemon directory.
  --enable-ntlm-fail-open Enable NTLM fail open, where a helper that fails one
                          of the Authentication steps can allow squid to still
                          authenticate the user. This has security
                          implications, and is deprecated
  --enable-external-acl-helpers="list of helpers"
                          Enable external_acl helpers support and thelpers
                          themselves. Default is to build all buildable
                          helpers and enable support. To disable support, use
                          --disable-external-acl-helpers. To build no helpers,

  --enable-stacktraces    Enable automatic call backtrace on fatal errors
  --enable-cpu-profiling  Enable instrumentation to try and understand how CPU
                          power is spent by squid, by enabling specific probes
                          in selected functions. New probes can only be added
                          by modifying the source code. It is meant to help
                          developers in optimizing performance of Squid
                          internal functions. If you are not developer you
                          should not enable this, as it slows squid down
                          somewhat. See lib/Profiler.c for more details.
  --enable-x-accelerator-vary
                          Enable support for the X-Accelerator-Vary HTTP
                          header. Can be used to indicate variance within an
                          accelerator setup. Typically used together with
                          other code that adds custom HTTP headers to the
                          requests.
  --disable-ipv6          Disable IPv6 support. The default is to probe system
                          capabilities on startup.
  --enable-zph-qos        Enable ZPH QOS support
  --enable-gnuregex       Compile GNUregex. Unless you have reason to use this
                          option, you should not enable it. This library file
                          is usually only required on Windows and very old
                          Unix boxes which do not have their own regex library
                          built in.
  --disable-translation   Prevent Squid generating localized error page
                          templates and manuals. Which is usually tried, but
                          may not be needed.
  --disable-auto-locale   This prevents Squid providing localized error pages
                          based on the clients request headers. When disabled
                          Squid requires explicit language configuration.
