Überblick
Cross-platform C++ GUI toolkit
Verlauf
FLTK, the Fast Light Tool Kit, is a lightweight cross-platform C++ GUI toolkit for Unix/Linux, Windows, and macOS, with OpenGL support and the FLUID interface designer.
Official FLTK sources say the toolkit was originally developed by Bill Spitzak and is now maintained by a small worldwide group of developers. Its README describes it as a compact C++ GUI toolkit for Unix/Linux, Windows, and macOS that avoids bloat while supporting modern GUI functionality and OpenGL.
FLTK's public history reaches back to the late 1990s. The official README lists copyright from 1998 onward, and the 1.0 change log records the 1.0 series through 1.0.11 in May 2001. Later release branches continued through the long-lived 1.1, 1.3, and 1.4 series.
FLTK has been adopted by developers who need a small native GUI toolkit with permissive LGPL-with-exception licensing and broad platform reach. The project does not provide binary distributions, instead pointing users to source releases and operating-system package managers.
The toolkit has stayed relevant in package collections because it builds small GUI utilities and ships useful developer commands such as fltk-config and FLUID, while avoiding heavier desktop-framework dependencies.
Developers use FLTK as a C++ library for native GUI applications and use FLUID to design interfaces and generate code. The fltk-config tool reports compile and link flags for downstream builds.
Modern FLTK builds use CMake, with source releases and generated documentation published by the project. FLTK 1.5 development removes autotools support and requires a C++11-capable compiler.
FLTK is package-nerd significant because it is a tiny but long-lived GUI toolkit with stable command-line helpers, cross-platform backends, bundled image-library considerations, OpenGL integration, and many downstream packages that depend on its headers and config script.
It also illustrates a common packaging transition: older autotools workflows coexisting with, and later yielding to, CMake-only builds.
