To build erlsass on Windows 64bit you need to provide GNU gcc and g++ compilers. Follow the steps below:

1. Download MinGW64 for Windows 64bit , and unzip to C:\mingw64.

2. Add C:\mingw64 to your Path environment variable. ( On Windows 10: Open the Start menu, type environment in the results click on Edit environment variables for your account. Select the Path entry and click on Edit. )

3. Open CMD or Powershell and execute gcc --version. It should show you the gcc version that is present. Do the same for g++. You are now done, please see the section Install to continue.
