 # Visual Studio 2019 <!-- omit in toc -->

 You can use Visual Studio 2019 to examine the samples (compile them and run them in an SDL window) or to build your own apps for the 32blit API.

 See [Building & Running On 32Blit](32blit.md) if you want to compile examples/projects to run on 32Blit.

 ## Requirements

 You will need Visual Studio 2019 (preferably version 16.4).

 Make sure you install C++ desktop development support.

 You will also need to download SDL2 development libraries from the [SDL homepage](https://www.libsdl.org/download-2.0.php). Here find the latest version of the VC development libraries (at the time of this writing SDL2-devel-2.0.10-VC.zip). Additionally, download SDL2_image from [here](https://www.libsdl.org/projects/SDL_image/) (SDL2_image-devel-2.0.5-VC.zip) and SDL2_net from [here](https://www.libsdl.org/projects/SDL_net/) (SDL2_net-devel-2.0.1-VC.zip).

 Place these in the `vs\sdl\` folder. You will need to merge the include/lib directories. If you are using CMake/Open Folder, these are downloaded automatically.


 There are two methods of building with Visual Studio:

 ## Option 1: Use the solution file

 This should be the most familiar option for existing Visual Studio users.

 The solutions and projects are made to use toolset version c142.

 The solution file is located at `vs\32blit.sln`. It contains two static linked libraries, _32blit_ and _32blit-sdl_ and all the examples that will compile to .EXE.

 ## Option 2: Use Visual Studio's built-in CMake support

 This has the advantage of being closer to the build for the device.

 1. Open Visual Studio

 2. `File` > `Open` > `Folder` and open the folder where you cloned this repo. (Alternatively, if you haven't cloned the repo yet, use `File` -> `Clone or check out code`)

 3. Build!

 To find the built files use `Project` > `CMake Cache` > `Open in Explorer`.

 ### Get started with your own game

 There is also a skeleton game project created for you at https://github.com/32blit/32blit-boilerplate . This is an empty skeleton with some comments to get you started with your own game (if you do not want to start tweaking one of the examples).

 ### Building your own game

 1. Open Visual Studio

 2. `File` > `Open` > `Folder` and open the folder containing your game.

 3. `Project` > `CMake Settings`.

 4. Scroll down to the CMake variables and wait for the list to load.

 5. Press the "Browse..." button next to `32BLIT_DIR`.

 6. Browse to the folder containing the 32blit repo.

 7. To add a release configuration, press "Add a new configuration..." (the plus button under "Configurations"), select "x64-Release" and repeat steps 4-6 on the new configuration.

 8. Save. It should configure successfully.

 9. Build!

 [More info about using CMake with Visual Studio](https://docs.microsoft.com/en-us/cpp/build/cmake-projects-in-visual-studio?view=vs-2019)

 ### Building for 32Blit

 1. Make sure the "Embedded and IoT development tools" component is installed from the `Linux development with C++` VS Workload.

 2. Open the CMake Settings (see above).

 3. Press "Add a new configuration..." and select "IoT-Release".

 4. Scroll down to "CMake toolchain file" and browse to `32blit.toolchain`

 5. (Optional) Change configuration name to something like "32Blit-Release"

 6. Save.

 7. Press "Edit JSON", scroll down to the new conficuration and delete the contents of the `variables` array. The result should look like this:
 ```jsonc
     // other configs...
     {
       "name": "32Blit-Release",
       "generator": "Ninja",
       "configurationType": "Release",
       "buildRoot": "${projectDir}\\out\\build\\${name}",
       "installRoot": "${projectDir}\\out\\install\\${name}",
       "cmakeCommandArgs": "",
       "buildCommandArgs": "",
       "ctestCommandArgs": "",
       "inheritEnvironments": [ "gcc-arm" ],
       "variables": [],
       "intelliSenseMode": "linux-gcc-arm",
       "cmakeToolchain": "[path...]/32blit-sdk/32blit.toolchain"
     }
     //...
 ```

 8. Select the new config and build!

 ## Troubleshooting

 If you see errors such as `Cannot open include file: 'SDL.h': No such file or directory` and `cannot open file 'SDL2.lib'` you've probably extracted the SDL development libraries wrong. Inside your sdl folder you should have the folders docs, include and lib not SDL2-2.0.10.
