X11-Basic is a dialect of the BASIC programming language with graphics capability that integrates features like shell scripting, CGI-Programming, and full graphical visualization into the easy to learn the basic language on modern computers.

The structure of the language is similar to the ATARI-ST GFA-BASIC.

This package includes the basic interpreter named XBasic and a set of different compilers. A compiler manager (XBC) is included, which makes standalone binaries out of the BASIC programs, which run more than ten times faster than the interpreted code. X11-Basic programs can also be compiled into bytecode (see XBBC). This bytecode can be understood by a virtual machine (see XBVM). Finally, the bytecode can be converted to C source files (see xb2c) which can be compiled with the GNU C compiler (or the tiny C compiler) to native executables.

Ancient ANSI-Basic programs (with line numbers) can be converted to X11-Basic with the bas2x11basic program (see the man page bas2x11basic(1) ).

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.

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/x11-basic]
--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

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-cryptography enable cryptographic features [default=no]
--enable-static only produce static libraries [default=no]
--enable-smallram make version siutable for systems with small RAM
[default=no]
--enable-german make german version [default=no]

Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-bluetooth support blutooth [default=yes]
--with-usb support USB [default=yes]
--with-readline support readline library [default=yes]
--with-framebuffer support framebuffer [default=no]
--with-sdl support SDL library [default=no]
--with-x use the X Window System [default=yes]
--with-x use the X Window System

Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, i.e., -L if you have libraries in a
nonstandard directory
LIBS libraries to pass to the linker, e.g. -l
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if
you have headers in a nonstandard directory
CPP C preprocessor
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.
