A GitHub Action to set up a Developer Command Prompt for Microsoft Visual C++.

This project was forked from https://github.com/ilammy/msvc-dev-cmd to support additional use-cases and to experiment further with GitHub Actions.

steps: - uses: TheMrMilchmann/setup-msvc-dev@v4 with: arch: x64

• arch – target architecture (required if at least one is set: sdk, toolselt, uwp, spectre)
  • native compilation:
    • x64
    • x86
  • cross-compilation: x86_amd64, x86_arm, x86_arm64, amd64_x86, amd64_arm, amd64_arm64
  • Check the Microsoft documentation for all possible options
• vs-path – the path to the Visual Studio installation
  • do not specify to use the latest installation
• 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 a VC++ compiler toolset
  • 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.YYYY for a specific full version number (e.g. 14.11.25503)
• uwp – set to true to build for Universal Windows Platform (i.e., for Windows Store)
• spectre – set to true to use Visual Studio libraries with spectre mitigations
• export-path-to-vcvarsall – the environment variable to store the path to vcvarsall.bat in
• export-path-to-vs – the environment variable to store the path to the Visual Studio installation in

This action is strictly following SemVer 2.0.0. Thus, it is recommended to pin the action against specific MAJOR version. This can be achieved by using the v${MAJOR} branch.

To get an overview about the action's versions, see the changelog.
