# How to Build

## Windows with Visual Studio's IDE

Use the provided project file (`example_sdl3_surface.vcxproj`) or open `imgui_examples.sln`.

## Windows with Visual Studio's CLI

Use `build_win32.bat` or directly:
```bat
set SDL3_DIR=path_to_your_sdl3_folder
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL3_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl3.cpp ..\..\backends\imgui_impl_sdlsurface3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl3_surface.exe /FoDebug/ /link /libpath:%SDL3_DIR%\lib\x86 SDL3.lib /subsystem:console
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL3_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl3.cpp ..\..\backends\imgui_impl_sdlsurface3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl3_surface.exe /FoDebug/ /link /libpath:%SDL3_DIR%\lib\x64 SDL3.lib /subsystem:console
```

## Linux and similar Unixes

Use the provided `Makefile` or directly:
```sh
c++ `pkg-config --cflags sdl3` -I .. -I ../.. -I ../../backends \
  main.cpp ../../backends/imgui_impl_sdl3.cpp ../../backends/imgui_impl_sdlsurface3.cpp ../../imgui*.cpp \
  -ldl `pkg-config --libs sdl3`
```

## macOS

Use the provided `Makefile` or directly:
```sh
brew install sdl3
c++ `pkg-config --cflags sdl3` -I .. -I ../.. -I ../../backends \
  main.cpp ../../backends/imgui_impl_sdl3.cpp ../../backends/imgui_impl_sdlsurface3.cpp ../../imgui*.cpp \
  -framework Cocoa -framework IOKit -framework CoreVideo `pkg-config --libs sdl3`
```

## Emscripten

Use `Makefile.emscripten`:
```sh
source /path/to/emsdk/emsdk_env.sh
make -f Makefile.emscripten
```

This produces `web/index.html`, `web/index.js`, and `web/index.wasm`.
