Set up MinGW-w64
================

[![Test](https://github.com/egor-tensin/setup-mingw/actions/workflows/test.yml/badge.svg)](https://github.com/egor-tensin/setup-mingw/actions/workflows/test.yml)

This GitHub action sets up MinGW-w64 in your workflow run.

1. Installs MinGW-w64 on either Ubuntu or Windows.
2. Fixes the infamous libwinpthread-1.dll [static linking issue].

[static linking issue]: https://stackoverflow.com/q/13768515/514684

Use it in your workflow like this:

    - name: Set up MinGW
      uses: egor-tensin/setup-mingw@v2
      with:
        platform: x64

* `x64` is the default value for the `platform` parameter and can be omitted.
Use `x86` if you want to build 32-bit binaries.
* Set the `cygwin` parameter to `1` to set up MinGW inside an existing Cygwin
installation (see [my other action] for setting up Cygwin itself).
* `cc` and `c++` executables are set up, pointing to the `*-gcc` and `*-g++`
executables.
Disable this by setting the `cc` parameter to `0`.
