ImGuinZ

This project aims to simply and easily build Dear ImGui (CImGui) / ImPlot (CImPlot) examples in Zig language with less external dependencies.

• ImGui / CImGui version 1.92.3 dock (2025/09)

• OS: Windows and Linux

• Frontends and Backends

  	GLFW	SDL3
  OpenGL3 backend	v	v
  SDLGPU3 backend	-	v
  vulkan backend	WIP	WIP

• Features

  • Included Font Awesome Icon fonts.
    
  • Included GLFW 3.4.0 static library (for Windows)
  • Included SDL3 libraries (for Windows)
  • Included STB libraries (only stb_image) for Load / Save images
  • Available ImPlot (CImPlot) with ImDrawIdx="unsigned int"
  • Enabled Input method (IME) flag with IMGUI_ENABLE_WIN32_DEFAULT_IME_FUNCTIONS

Prerequisites

• Zig compiler version confirmed

  • Windows: zig-x86_64-windows-0.15.1.zip
  • Linux: zig-x86_64-linux-0.15.1.tar.xz

• WindowsOS

  • Windows10 or later
  • MSys2/MinGW basic commands (make, rm, cp, strip ...)

    pacman -S make mingw-w64-x86_64-{gcc,vulkan-headers,vulkan-loader}
    

• Linux OS (Ubuntu / Debian families)

   sudo apt install lib{opengl-dev,gl1-mesa-dev,glfw3,glfw3-dev,xcursor-dev,xinerama-dev,xi-dev} git make
  

  • SDL3
    If you are using Debian13, add

    sudo apt install libsdl3-dev
    

    otherwise install SDL3 manually

Build and run

git clone https://github.com/dinau/imguinz
cd imguinz/examples/glfw_opengl3              # cd one of examples
make run                                      # or  zig build --release=fast run
