README - Fast Light Tool Kit (FLTK) Version 1.1.3
-------------------------------------------------
WHAT IS FLTK?
The Fast Light Tool Kit ("FLTK", pronounced "fulltick") is a
a cross-platform C++ GUI toolkit for UNIX(r)/Linux(r) (X11),
Microsoft(r) Windows(r), and MacOS(r) X. FLTK provides
modern GUI functionality without the bloat and supports 3D
graphics via OpenGL(r) and its built-in GLUT emulation. 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://www.fltk.org/documentation.php
BUILDING AND INSTALLING FLTK UNDER UNIX AND MacOS X
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-cygwin - Enable the Cygwin libraries (WIN32)
--enable-debug - Enable debugging code & symbols
--disable-gl - Disable OpenGL support
--enable-shared - Enable generation of shared libraries
--enable-threads - Enable multithreading support
--enable-xdbe - Enable the X double-buffer extension
--enable-xft - Enable the Xft library (anti-aliased fonts)
--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 VC++ 6.0 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
with the CygWin tools, use the supplied configure script
as specified in the UNIX section above:
sh configure ...options...
To build using other 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:

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. You can also submit a
bug on the SourceForge pages.
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).
