### Windows

To build SourceKit-LSP on Windows, the swift-syntax libraries need to be built as dynamic libraries so we do not exceed the maximum symbol limit in a single binary. Additionally, the equivalent search paths to the linux build need to be passed. Run the following in Command Prompt.
To build SourceKit-LSP on Windows, the swift-syntax libraries need to be built as dynamic libraries so we do not exceed the maximum symbol limit in a single binary. Additionally, the equivalent search paths to the linux build need to be passed. Run the following in PowerShell.

```cmd
> set SWIFTSYNTAX_BUILD_DYNAMIC_LIBRARY=1
> swift build -Xcc -I%SDKROOT%\usr\include -Xcc -I%SDKROOT%\usr\include\Block
```ps
> $env:SWIFTSYNTAX_BUILD_DYNAMIC_LIBRARIES = 1; swift test -Xcc -I -Xcc $env:SDKROOT\usr\include -Xcc -I -Xcc $env:SDKROOT\usr\include\Block
```

To work on SourceKit-LSP in VS Code, add the following to your `settings.json`, for other editors ensure that the `SWIFTSYNTAX_BUILD_DYNAMIC_LIBRARY` environment variable is set when launching `sourcekit-lsp`.
