The Go Programming Language

go-legacy-win7 is a fork of the Go programming language that maintains support for Windows 7 and Windows Server 2008 R2, and allows for deprecated go get behaviour. This project aims to provide a stable Go environment for users who need to support legacy Windows systems or prefer the traditional Go workflow.

Differences from Upstream Go

1. Windows 7 and Windows Server 2008 R2 Support
   While the official Go project has dropped support for Windows 7 and Windows Server 2008 R2, this fork maintains compatibility with these legacy Windows systems.

   Tested on Windows 7 RTM (build 7600) — no updates required — through Windows 11 24H2

2. Classic go get Behaviour
   This fork allows for the deprecated go get behaviour when GO111MODULE is set to "off" or "auto". This means:

   • In GOPATH/src, go get and go install can operate in GOPATH mode.
   • Outside of GOPATH/src, these commands can use module-aware mode when appropriate.

3. Compatibility Notes
   Please be aware that some newer Go features may not be fully compatible with Windows 7 or Windows Server 2008 R2. We try to maintain as much functionality as possible, but some limitations may exist.

Changes in Each Release

Current release includes the following modifications:

• Switched back to RtlGenRandom from ProcessPrng, which breaks Win7/2008R2 (reverted 693def1)
• Added back LoadLibraryA fallback to load system libraries (reverted a17d959)
• Added back sysSocket fallback for socket syscalls (reverted 7c1157f)
• Added back Windows 7 console handle workaround (reverted 48042aa)
• Added back 5ms sleep on Windows 7/8 in (*Process).Wait (reverted f0894a0)
• Restored deprecated go get behavior for use outside modules (reverted de4d503)
• Reverted to the previous removeall_noat variant for Windows (fixed issue #2)
• Rolled back race_windows.syso to the previous compatible version (fixed issue #3)
• Includes all improvements and bug fixes from the corresponding upstream Go release

The Windows binary provided here also supports Windows 7 and Windows Server 2008 R2

Before you begin

To avoid PATH/GOROOT conflicts and mixed toolchains, uninstall any existing Go installation first.

Windows Installation

1. Download the go-legacy-win7-<version>.windows_<arch>.zip file.
2. Extract the ZIP to C:\ (or any preferred location). This will create a go-legacy-win7 folder.
3. Add the following to your system environment variables:
   • Add C:\go-legacy-win7\bin (or your chosen path) to the system PATH.
   • Set GOROOT to C:\go-legacy-win7 (or your chosen path).
4. Add the following to your user environment variables:
   • Add %USERPROFILE%\go\bin to the user PATH.
   • Set GOPATH to %USERPROFILE%\go.

macOS and Linux Installation

1. Download the appropriate go-legacy-win7-<version>.<os>_<arch>.tar.gz file.

   • For macOS: go-legacy-win7-<version>.darwin_<arch>.tar.gz
   • For Linux: go-legacy-win7-<version>.linux_<arch>.tar.gz

2. Extract the archive to /usr/local:

   sudo tar -C /usr/local -xzf go-legacy-win7-<version>.<os>_<arch>.tar.gz
   

3. Add the following to your shell configuration file:

   • For bash, add to ~/.bash_profile or ~/.bashrc
   • For zsh, add to ~/.zshrc

   export GOROOT=/usr/local/go-legacy-win7
   export GOPATH=$HOME/go
   export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
   

4. Apply the changes:

   • For bash: source ~/.bash_profile or source ~/.bashrc
   • For zsh: source ~/.zshrc

   Note:

   • On macOS Catalina and later, zsh is the default shell.
   • On most Linux distributions, bash is the default shell.

After installation, verify the installation by opening a new terminal and running:

go version
