`configure' configures Squid Web Proxy 5.6 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.
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]

the -march=native parameter. This flag disables the
optimization. The default is to auto-detect compiler
support and use where available.

static compiler error-checks enabled. This flag
disables the behavior

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.

HTTP header to try to find the IP address of the
original or indirect client when a request has been
forwarded through other proxies.

--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.

header. Can be used to indicate variance within an
accelerator setup. Typically used together with
other code that adds custom HTTP headers to the

capabilities on startup.
--enable-zph-qos Enable ZPH QOS support

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.
--enable-translation Generate the localized error page templates and
manuals. Which can also be downloaded from
http://www.squid-cache.org/Versions/langpack/.
--disable-auto-locale This prevents Squid providing localized error pages
based on the clients request headers. When disabled
Squid requires explicit language configuration.
