\`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
-V, --version display version information and exit
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX [/]
By default, \`make install' will install all the files in \'/sbin',
\`/libexec', etc. You can specify
an installation prefix other than \`/' using \`--prefix',
for instance \`--prefix=$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [PREFIX/bin]
--sbindir=DIR system admin executables [PREFIX/sbin]
--libexecdir=DIR program executables [PREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [PREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--mandir=DIR man documentation [PREFIX/man]
System types:
--build=BUILD configure for building on BUILD [guessed]
--host=HOST build programs to run on HOST [BUILD]
--target=TARGET configure for building compilers for TARGET [HOST]
Optional Features:
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
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>
CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
headers in a nonstandard directory <include dir>
CPP 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.
