Configurations | Running a C++ FLTK Program on Windows 11 Using Premake 5

The Fast Light Tool Kit (“FLTK”) is a cross-platform C++ GUI toolkit for different operation systems.

Step 0: Download The FILT Library And Compile It

In the official link, download the latest library source code.

In the directory ide/VisualC2010/ , open up the fltk.sln file, and compile it. Build the solution both in the debug and release mode. It will generate static libraries.

Step 1: Create a project using premake 5

Use the lua file below to generate the project.

workspace "FltkDemo"
configurations { "Debug", "Release", "Dist" }
 platforms "x86"
 architecture "x86"
 startproject "Sandbox"
 location "project-files"
 configurations
 {
  "Debug",
  "Release",
  "Dist",
 }
 filter "configurations:Debug"
  defines { "DEBUG" }
  runtime "Debug"
  symbols "on"
 filter "configurations:Release or Dist"
  defines { "NDEBUG" }
  runtime "Release"
  optimize "on"
  symbols "off"

 outputdir = "%{cfg.buildcfg}-%{cfg.system}-%{cfg.architecture}"

project "Sandbox"
 location "Sandbox"
 kind "ConsoleApp"
 language "C++"
 cppdialect "C++latest"
 staticruntime "off"
 targetdir ("bin/%{outputdir}/%{prj.name}")
 objdir ("bin-int/%{outputdir}/%{prj.name}")
 
 files
 {
  "%{prj.name}/src/**.h",
  "%{prj.name}/src/**.cpp",
 }
 
 includedirs
 {
  "./vendor/fltk-release-1.3.9/",
 }
 
 libdirs {
  "./vendor/fltk-release-1.3.9/lib/"
 }
 
 filter "configurations:Debug"
  links
  {
   "fltkd.lib",
   "fltkformsd.lib",
   "fltkgld.lib",
   "fltkimagesd.lib",
   "fltkjpegd.lib",
   "fltkpngd.lib",
   "fltkzlibd.lib",
  }
 filter "configurations:Release or Dist"
  links
  {
   "fltk.lib",
   "fltkforms.lib",
   "fltkgl.lib",
   "fltkimages.lib",
   "fltkjpeg.lib",
   "fltkpng.lib",
   "fltkzlib.lib",
  }

Step2: Write an Application

#include <FL/Fl.H>
#include <FL/Fl_Window.H>
#include <FL/Fl_Box.H>

int main(int argc, char** argv) {
 Fl_Window* window = new Fl_Window(340, 180);
 Fl_Box* box = new Fl_Box(20, 40, 300, 100, "Hello, World!");
 box->box(FL_UP_BOX);
 box->labelfont(FL_BOLD + FL_ITALIC);
 box->labelsize(36);
 box->labeltype(FL_SHADOW_LABEL);
 window->end();
 window->show(argc, argv);
 return Fl::run();
}

This code will create a new window application.
