README - Fast Light Tool Kit (FLTK) Version 1.4.0 ------------------------------------------------- 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 Mac OS 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". To install additional files and icons to be used by the main desktop environments such as KDE, GNOME and XFCE, you will also need to run "make install-desktop" as root. SVN USERS If you've just checked out a fresh copy of FLTK from SVN, you'll need to generate an initial version of 'configure' by running 'make makeinclude'. (We don't include a copy of configure in svn) MAKE TARGETS make -- builds the library + test programs (does not install) make install -- builds and installs make clean -- clean for a rebuild make distclean -- like 'clean', but also removes docs, configure, fltk-config ( cd src; make ) -- builds just the fltk libraries BUILDING FLTK UNDER MICROSOFT WINDOWS There are two ways to build FLTK under Microsoft Windows. The first is to use the Visual C++ project files under the "ide/" directory. See the file ide/README.IDE for more info. The second method is to use a GNU-based development tool. To build with the Cygwin or MinGW tools, use the supplied configure script as specified in the UNIX section above: sh configure ...options... BUILDING HTML DOCUMENTATION If you want to build the HTML documentation: ( cd documentation && make html ) If you want to build the PDF documentation: ( cd documentation && make pdf ) FLTK uses doxygen for documentation, so you'll at least need doxygen installed for creating html docs, and LaTeX for creating PDF docs.
