README - Fast Light Tool Kit (FLTK) Version 1.0
-----------------------------------------------
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
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.
You can run configure yourself to get the exact setup you need.
Type "./configure <options>". The "--enable-windows-style" option
will make the FLTK widgets look more like their Microsoft Windows
counterparts. Other 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:
cp makefiles/makeinclude.<env> makeinclude
cp makefiles/config.<env> config.h
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:
cp makefiles/Makefile.os2x Makefile
cp makefiles/makeinclude.os2x makeinclude
cp makefiles/config.os2x config.h
make

REPORTING BUGS
To report a bug in FLTK, send an email to "fltk-bugs@easysw.com".
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@easysw.com".
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.ssec.wisc.edu/~brianp/Mesa.html".
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).
