You can use the help flag to see everything that can be done with configure.
Code:
john@cave:~/emc/src$ ./configure --help
john@cave:~/emc/src$ ./configure --help
`configure' configures LinuxCNC 2.9.0~pre1 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
[run-in-place]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, `make install' will install all the files in
`run-in-place/bin', `run-in-place/lib' etc. You can specify
an installation prefix other than `run-in-place' 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]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--runstatedir=DIR modifiable per-process data [LOCALSTATEDIR/run]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR man documentation [DATAROOTDIR/man]
--docdir=DIR documentation root [DATAROOTDIR/doc/linuxcnc]
--htmldir=DIR html documentation [DOCDIR]
--dvidir=DIR dvi documentation [DOCDIR]
--pdfdir=DIR pdf documentation [DOCDIR]
--psdir=DIR ps documentation [DOCDIR]
X features:
--x-includes=DIR X include files are in DIR
--x-libraries=DIR X library files are in DIR
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-non-distributable
To build LinuxCNC even if a license problem would
render the resulting binaries non-distributable
under the terms of the LinuxCNC license
--enable-simulator Deprecated! Use --with-realtime=uspace instead.
--enable-toolnml Use nml for tooldata, default is mmap
--disable-userspace-pci Disable userspace PCI access (use this if libudev is
unavailable).
--disable-gtk Disable the parts of LinuxCNC that depend on GTK.
--disable-gtk2 Disable the parts of LinuxCNC that depend on GTK2.
Ónly needed for classicladder)
--enable-build-documentation=FORMAT
Build documentation. FORMAT may be "Y" for both or
"pdf" or "html" if only one format is desired.
--disable-build-documentation-translation
Disable building documentation in languages other
than English.
--disable-check-runtime-deps
Skip checks for runtime requirements not needed
during the build process.
--disable-nls Don't use NLS.
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-realtime=PATH Path where RTAI is installed, or "uspace" for POSIX
userspace.
--with-kernel-headers=PATH
Location for kernel headers.
--with-libmodbus Specify whether or not to build the drivers that use
libmodbus (defaults to "yes").
--with-libusb-1.0 Specify whether or not to build the drivers that use
libusb-1.0 (defaults to "yes").
--with-kbuild Specify if your kernel uses kbuild or not.
--with-module-dir=PATH Installation directory for kernel modules.
--with-rmmod=PATH Location of the rmmod program to use.
--with-insmod=PATH Location of the insmod program to use.
--with-boost[=ARG] use Boost library from a standard location
(ARG=yes), from the specified location (ARG=<path>),
or disable it (ARG=no) [ARG=yes]
--with-boost-libdir=LIB_DIR
Force given directory for boost libraries. Note that
this will override library path detection, so use
this parameter only if default library detection
fails and you know exactly where your boost
libraries are located.
--with-boost-python specify yes/no or the boost python library or suffix
to use
--with-tclConfig=PATH Specify the path to tclConfig.
--with-tkConfig=PATH Specify the path to tkConfig.
--with-x use the X Window System
--with-locale-dir=DIR Location of the locale file(s) [DATADIR/locale].
Some influential environment variables:
CXX C++ compiler command
CXXFLAGS 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>
CC C compiler command
CFLAGS C compiler flags
CPP C preprocessor
PYTHON_VERSION
The installed Python version to use, for example '2.3'. This
string will be appended to the Python interpreter canonical
name.
XMKMF Path to xmkmf, Makefile generator for X Window System
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
