Sample appveyor.yml for Ruby C extension

I am trying to set up an appveyor.yml for a Ruby C extension. I haven't been able to figure out how to get the compile started. I've tried the build_script option but make does not seem to exist. Has anyone done this before and if so do you have an example?

    Hi Peter,

    Please try C:\Ruby23\DevKit\bin or C:\Ruby23-x64\DevKit\bin folders.

    Note that you can check software installed on build worker here and also connect to build worker with RDP to look closer.

    Thanks, that got me further but no success on the compiler. If you are willing to offer more advice here is what I have so far for

    version: 1.0.{build}-{branch}

    image: Visual Studio 2015

      APPVEYOR_RDP_PASSWORD: fixm3-wtf
      RUBY_VERSION: 23-x64
      PATH: C:\Ruby%RUBY_VERSION%\bin;C:\Ruby23-x64\DevKit\bin;C:\mingw-w64\x86_64-6.3.0-posix-seh-rt_v5-rev1;%PATH%
    build: off

      - ruby -v
      - make -v

      - cd C:\projects\oj\ext\oj
      - ruby extconf.rb
      - make

    I was able to make it work with this path in my fork:

    PATH: c:\Ruby%RUBY_VERSION%\DevKit\mingw\bin;C:\Ruby%RUBY_VERSION%\bin;C:\Ruby%RUBY_VERSION%\DevKit\bin;C:\mingw-w64\x86_64-6.3.0-posix-seh-rt_v5-rev1;%PATH%
    adding mingw\bin helps it to find way to x86_64-w64-mingw32-gcc.exe

    Awesome! It works. Time to get the AppVeyor badge set up.
