README - Fast Light Tool Kit (FLTK) Version 1.1.11 -------------------------------------------------- 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 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. 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://www.fltk.org/str.php [for reporting bugs] http://www.fltk.org/software.php [source code] - FTP: http://ftp.easysw.com/pub/fltk ftp://ftp.easysw.com/pub/fltk ftp://ftp2.easysw.com/pub/fltk ftp://ftp.funet.fi/pub/mirrors/ftp.easysw.com/pub/fltk ftp://linux.mathematik.tu-darmstadt.de/pub/linux/mirrors/misc/fltk ftp://gd.tuwien.ac.at/hci/fltk - EMail: fltk@fltk.org [see instructions below] To send a message to the FLTK mailing list ("fltk@fltk.org") you must first join the list.
