# 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:
|
||
- `x64` (default) or its synonyms: `amd64`, `win64`
|
||
- `x86` or its synonyms: `win32`
|
||
- 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
|
||
# ...
|
||
```
|
||
|
||
## Caveats
|
||
|
||
### Name conflicts with `shell: bash`
|
||
|
||
Using `shell: bash` in Actions may shadow some of the paths added by MSVC.
|
||
In particular, `link.exe` (Microsoft C linker) is prone to be shadowed by `/usr/bin/link` (GNU filesystem link tool).
|
||
|
||
Unfortunately, this happens because GitHub Actions unconditionally *prepend* GNU paths when `shell: bash` is used,
|
||
on top of any paths set by `msvc-dev-cmd`, every time at the start of each new step.
|
||
Hence, there aren't many non-destructive options here.
|
||
|
||
If you experience compilation errors where `link` complains about unreasonable command-line arguments,
|
||
“extra operand *something-something*” – that's probably it.
|
||
Recommended workaround is to remove `/usr/bin/link` if that interferes with your builds.
|
||
If this is not acceptable, please file an issue, then we'll figure out something better.
