MinGW-W64 GCC-8.1.0 Mirror

Official Website: MinGW-W64

Installation Instructions

1. Determine the MingGW architecture:

• Version: 8.1.0
• Architecture: i686 or x86_64
  • i686: is the 32-bit version
  • x86_64: is the 64-bit version of the OS (Recommended)
• Threads: posix or win32
  • posix: Enable C++11/C11 multithreading features. (Recommended)
    • Note: Makes libgcc depend on libwinpthreads, so that even if you don't directly call pthreads API, you'll be distributing the winpthreads DLL. There's nothing wrong with distributing one more DLL with your application.
  • win32: No C++11 multithreading features.
• Exception: dwarf or sjlj
  • seh: Available for 64-bit GCC 4.8 (x86_64) (Recommended)
    • Performance: Zero overhead exception
  • dwarf: Available for 32 bit only (i686).
    • Performance: No permanent runtime overhead.
  • sjlj: Available for 32 bit and 64 bit.
    • Performance: ~15% in exception heavy code
• Build revision: 0

Recommended for Windows 10 x64:

• Version = 8.1.0
• Architecture = x86_64 (x64 OS)
• Threads = posix (Allow threading)
• Exception = seh (Zero overhead exception)
• Build revision = 0

2. Download the appropriate 7-zip (*.7z) file to your local machine:

• ARCHITECTURE-VERSION-THREAD-EXCEPTION-*.7z

Recommended for Windows 10 x64:

• x86_64-8.1.0-release-posix-seh-rt_v6-rev0.7z

3. Unzip the 7-Zip file to C:\mingw-w64\mingw64

4. Add C:\mingw-w64\mingw64\bin to PATH

Batch File:

echo off
set PATH=C:\mingw-w64\mingw64\bin;%PATH%
rem echo %PATH%
rem cd "C:\mingw-w64\mingw64\bin"
cd "C:\"
"C:\WINDOWS\system32\cmd.exe"

5. Open a new cmd.exe and verify the GCC compiler is setup.

>>> gcc -v

Background

The mingw-w64-install.exe online installer is a minimal application that downloads the correct MingGW architecture version from SourceForge using a file lookup repository.txt here:

The installer downloads the appropriate 7-Zip MinGW file and extracts the content to C:\wingw-w64 or C:\Program Files (x86)\mingw-w64. The \mingw64\bin is then registered with PATH environment.
