Usage: $0 [OPTION]... [VAR=VALUE]... [TARGET]
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.
Installation directories:
--prefix=PREFIX main installation prefix [/usr/local]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--rundir=DIR pidfile and unix sockets [LOCALSTATEDIR/run]
--libdir=DIR object code libraries [EPREFIX/lib]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--mandir=DIR man documentation [DATAROOTDIR/man]
Optional features:
--enable-debug build with debugging information [disabled]
--enable-warnings build with recommended warnings flags [enabled]
--enable-werror build with -Werror [disabled]
--enable-lua build Lua client binding [disabled]
--disable-doc do not build manual pages [enabled]
--with-luapc=LUAPC build Lua client binding, using LUAPC pkg-config
package [disabled]
Some influential environment variables:
CC C compiler command [detected]
CFLAGS C compiler flags [-Os -pipe ...]
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
Use these variables to override the choices made by configure.
