# msvc-dev-cmd [GitHub Action](https://github.com/features/actions) for configuring Developer Command Prompt for Microsoft Visual C++. This sets up the environment for compiling C/C++ code from command line. Supports Windows. Does nothing on Linux and macOS. ## Inputs - `arch` – target architecture - native compilation: `x86`, `x64` (default), `amd64` (synonym for x64) - cross-compilation: `x86_amd64`, `x86_arm`, `x86_arm64`, `amd64_x86`, `amd64_arm`, `amd64_arm64` - `sdk` – Windows SDK to use - do not specify to use the default SDK - or specify full Windows 10 SDK number (e.g, `10.0.10240.0`) - or write `8.1` to use Windows 8.1 SDK - `toolset` – select VC++ compiler toolset version - do not specify to use the default toolset - `14.0` for VC++ 2015 Compiler Toolset - `14.XX` for the latest 14.XX toolset installed (e.g, `14.11`) - `14.XX.YYYYY` for a specific full version number (e.g, `14.11.25503`) - `uwp` – set `true` to build for Universal Windows Platform (i.e., for Windows Store) - `spectre` – set `true` to use Visual Studio libraries with [Spectre](https://meltdownattack.com) mitigations ## Example usage ```yaml jobs: test: - uses: actions/checkout@v1 - uses: ilammy/msvc-dev-cmd@v1 - name: Build something requiring CL.EXE run: | cmake -G "NMake Makefiles" . nmake # ... ``` ## License MIT, see [LICENSE](LICENSE).
