`configure' configures this package 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]

  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX

                          [PREFIX]

By default, `make install' will install all the files in

`/usr/local/bin', `/usr/local/lib' etc.  You can specify

an installation prefix other than `/usr/local' using `--prefix',

for instance `--prefix=$HOME'.

For better control, use the options below.

                          for an Oracle Instant Client SDK.

                          For example on Linux with 11.2 RPMs use:

                            --with-pdo-oci=instantclient,/usr,11.2

                          With 10.2 RPMs use:

                          PDO: Support for 'flavour' ODBC driver.

              include and lib dirs are looked for under 'dir'.

              'flavour' can be one of:  ibm-db2, iODBC, unixODBC, generic

              If ',dir' part is omitted, default for the flavour

              you have selected will be used. e.g.:

                --with-pdo-odbc=unixODBC

              will check for unixODBC under /usr/local. You may attempt

              to use an otherwise unsupported driver using the \"generic\"

              flavour.  The syntax for generic ODBC support is:

                --with-pdo-odbc=generic,dir,libname,ldflags,cflags

              When built as 'shared' the extension filename is always pdo_odbc.so

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

  YACC        The `Yet Another C Compiler' implementation to use. Defaults to

              the first program found out of: `bison -y', `byacc', `yacc'.

  YFLAGS      The list of arguments that will be passed by default to $YACC.

              This script will default YFLAGS to the empty string to avoid a

              default value of `-d' given by some make applications.

  CXX         C++ compiler command

  CXXFLAGS    C++ compiler flags

  CXXCPP      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.
