How to Build

  • On Windows with Visual Studio's CLI
set SDL2DIR=path_to_your_sdl2_folder
cl /Zi /MD /I %SDL2DIR%\include> /I ..\.. main.cpp imgui_impl_sdl.cpp ..\..\imgui*.cpp /link /LIBPATH:%SDL2DIR%\lib SDL2.lib SDL2main.lib
  • On Linux and similar Unixes
c++ `sdl2-config --cflags` -I ../.. main.cpp imgui_impl_sdl.cpp ../../imgui*.cpp `sdl2-config --libs` -lGL -o sdl2example
  • On Mac OS X
brew install sdl2
c++ `sdl2-config --cflags` -I ../.. main.cpp imgui_impl_sdl.cpp ../../imgui*.cpp `sdl2-config --libs` -framework OpenGl -o sdl2example
