• Using SDL with Microsoft Visual C++
  ===================================
  
  ### by [Lion Kimbro](mailto:snowlion@sprynet.com) with additions by [James Turk](mailto:james@conceptofzero.net)
  
  You can either use the precompiled libraries from the [SDL](https://www.libsdl.org/download.php) web site, or you can build SDL
  yourself.
  
  ### Building SDL
  
  0. To build SDL, your machine must, at a minimum, have the DirectX9.0c SDK installed. It may or may not be retrievable from
  the [Microsoft](https://www.microsoft.com) website, so you might need to locate it [online](https://duckduckgo.com/?q=directx9.0c+sdk+download&t=h_&ia=web).
  _Editor's note: I've been able to successfully build SDL using Visual Studio 2019 **without** the DX9.0c SDK_
  
  1. Open the Visual Studio solution file at `./VisualC/SDL.sln`.
  
  2. Your IDE will likely prompt you to upgrade this solution file to whatever later version of the IDE you're using. In the `Retarget Projects` dialog,
  all of the affected project files should be checked allowing you to use the latest `Windows SDK Version` you have installed, along with
  the `Platform Toolset`.
     
  If you choose *NOT* to upgrade to use the latest `Windows SDK Version` or `Platform Toolset`, then you'll need the `Visual Studio 2010 Platform Toolset`.
  
  3. Build the `.dll` and `.lib` files by right clicking on each project in turn (Projects are listed in the _Workspace_ 
  panel in the _FileView_ tab), and selecting `Build`.
  
  You may get a few warnings, but you should not get any errors.
  
  Later, we will refer to the following `.lib` and `.dll` files that have just been generated:
  
  -   `./VisualC/Win32/Debug/SDL2.dll` or `./VisualC/Win32/Release/SDL2.dll`
  -   `./VisualC/Win32/Debug/SDL2.lib` or `./VisualC/Win32/Release/SDL2.lib`
  -   `./VisualC/Win32/Debug/SDL2main.lib` or `./VisualC/Win32/Release/SDL2main.lib`
  
  _Note for the `x64` versions, just replace `Win32` in the path with `x64`_
  
  ### Creating a Project with SDL
  
  - Create a project as a `Win32 Application`.
  
  - Create a C++ file for your project.
  
  - Set the C runtime to `Multi-threaded DLL` in the menu:
  `Project|Settings|C/C++                  tab|Code Generation|Runtime Library `.
  
  - Add the SDL `include` directory to your list of includes in the menu:
  `Project|Settings|C/C++ tab|Preprocessor|Additional include directories `
  
  *VC7 Specific: Instead of doing this, I find it easier to add the
  include and library directories to the list that VC7 keeps. Do this by
  selecting Tools|Options|Projects|VC++ Directories and under the "Show
  Directories For:" dropbox select "Include Files", and click the "New
  Directory Icon" and add the [SDLROOT]\\include directory (e.g. If you
  installed to c:\\SDL\\ add c:\\SDL\\include). Proceed to change the
  dropbox selection to "Library Files" and add [SDLROOT]\\lib.*
  
  The "include directory" I am referring to is the `./include` folder.
  
  Now we're going to use the files that we had created earlier in the *Build SDL* step.
  
  Copy the following file into your Project directory:
  
  -   `SDL2.dll`
  
  Add the following files to your project (It is not necessary to copy them to your project directory):
  
  -   `SDL2.lib`
  -   `SDL2main.lib`
  
  To add them to your project, right click on your project, and select
  `Add files to project`.
  
  **Instead of adding the files to your project, it is more desirable to add them to the linker options: Project|Properties|Linker|Command Line
  and type the names of the libraries to link with in the "Additional Options:" box. Note: This must be done for each build configuration
  (e.g. Release,Debug).**
  
  ### Hello SDL2
  
  Here's a sample SDL snippet to verify everything is setup in your IDE:
  
  ```
      #include "SDL.h"
  
      int main( int argc, char* argv[] )
      {
          const int WIDTH = 640;
          const int HEIGHT = 480;
          SDL_Window* window = NULL;
          SDL_Renderer* renderer = NULL;
  
          SDL_Init(SDL_INIT_VIDEO);
          window = SDL_CreateWindow("SDL2 Test", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, WIDTH, HEIGHT, SDL_WINDOW_SHOWN);
          renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
   
          SDL_DestroyRenderer(renderer);
          SDL_DestroyWindow(window);
          SDL_Quit();
          return 0;
      }
   ```               
  
  ### That's it!
  
  I hope that this document has helped you get through the most difficult part of using the SDL: installing it. 
  Suggestions for improvements should be posted to the [Github Issues](https://github.com/libsdl-org/SDL/issues).
