README - Fast Light Tool Kit (FLTK) Version 1.0.10
--------------------------------------------------

WHAT IS FLTK?

    The Fast Light Tool Kit ("FLTK", pronounced "fulltick") is a
    LGPL'd C++ graphical user interface toolkit for X (UNIX(r)),
    OpenGL(r), and Microsoft(r) Windows(r) NT 4.0, 95, or 98. It
    was originally developed by Mr. Bill Spitzak and is
    currently maintained by a small group of developers across
    the world with a central repository in the US.


LICENSING

    FLTK comes with complete free source code. FLTK is available
    under the terms of the GNU Library General Public License.
    Contrary to popular belief, it can be used in commercial
    software! (Even Bill Gates could use it.) 


ON-LINE DOCUMENTATION

    All of the documentation is in HTML in the subdirectory
    "documentation". The "index.html" file should be your
    starting point.  PostScript(tm) and PDF versions of this
    documentation is also available from the FLTK web site at:

        http://fltk.easysw.com/documentation.html


BUILDING AND INSTALLING FLTK UNDER UNIX

    In most cases you can just type "make".  This will run
    configure with the default (no) options and then compile
    everything.

    FLTK uses GNU autoconf to configure itself for your UNIX
    platform. The main things that the configure script will
    look for are the X11, OpenGL (or Mesa), and JPEG header and
    library files.  Make sure that they are in the standard
    include/library locations.  If they aren't you need to
    define the CFLAGS, CXXFLAGS, and LDFLAGS environment
    variables.

    If you aren't using "gcc", "g++", "c++", or "CC" for your
    C++ compiler, you'll also need to set the CXX environment
    variable. Similarly, if you aren't using "gcc" or "cc" for
    your C compiler you'll need to set the CC environment
    variable.

    You can run configure yourself to get the exact setup you
    need. Type "./configure <options>".  Options include:

	--enable-debug          - Enable debugging code & symbols
	--enable-shared         - Enable generation of shared libraries

	--bindir=/path          - Set the location for executables
                        	  [default = /usr/local/bin]
	--libdir=/path          - Set the location for libraries
                        	  [default = /usr/local/lib]
	--includedir=/path      - Set the location for include files.
                        	  [default = /usr/local/include]
	--prefix=/dir           - Set the directory prefix for files
                        	  [default = /usr/local]

    When the configure script is done you can just run the
    "make" command. This will build the library, FLUID tool, and
    all of the test programs.

    To install the library, become root and type "make
    install".  This will copy the "fluid" executable to
    "bindir", the header files to "includedir", and the library
    files to "libdir".


BUILDING FLTK UNDER MICROSOFT WINDOWS

    There are two ways to build FLTK under Microsoft Windows. 
    The first is to use the 5.0 project files under the
    "visualc" directory.  Just open (or double-click on) the
    "fltk.dsw" file to get the whole shebang.

    The second method is to use a GNU-based development tool
    with the files in the "makefiles" directory.  To build using
    one of these tools simply copy the appropriate makeinclude
    and config files to the main directory and do a make:

	copy makefiles\Makefile.<env> Makefile
	make


BUILDING FLTK UNDER OS/2

    The current OS/2 build requires XFree86 for OS/2 to work.  A
    native Presentation Manager version has not been implemented
    yet (volunteers are welcome!).

    To build the XFree86 version of FLTK for OS/2, copy the
    appropriate makeinclude and config files to the main
    directory and do a make:

        copy makefiles\Makefile.os2x Makefile
	make


INTERNET RESOURCES

    FLTK is available on the 'net in a bunch of locations:

	- WWW:   http://www.fltk.org
	         http://fltk.sourceforge.net

	- EMail: fltk@fltk.org [see instructions below]
        	 fltk-bugs@fltk.org [for reporting bugs]

    To send a message to the FLTK mailing list ("fltk@fltk.org")
    you must first join the list.  Non-member submissions are
    blocked to avoid problems with SPAM.

    To join the FLTK mailing list, send a message to
    "majordomo@fltk.org" with "subscribe fltk" in the message
    body.  A digest of this list is available by subscribing to
    the "fltk-digest" mailing list.


REPORTING BUGS

    To report a bug in FLTK, send an email to
    "fltk-bugs@fltk.org". Please include the FLTK version,
    operating system & version, and compiler that you are using
    when describing the bug or problem.

    For general support and questions, please use the FLTK
    mailing list at "fltk@fltk.org".


MESA

    Currently the best way to get OpenGL on your Linux system is
    to use Mesa.  FLTK has been tested with Mesa on several
    machines (and also with "real" OpenGL on SGI machines). Mesa
    is available at:

        http://www.mesa3d.org

    The configure script will not see Mesa unless it is
    installed as either libGL or libMesaGL.  If you don't want
    to do this you will have to edit config.h (set HAVE_GL to 1)
    and makeinclude (add the libraries).
