Cross Compilation from Windows to Linux: A Step-by-Step Guide

For those seeking to cross-compile Go programs from a Windows environment to a Linux target, encountering the "runtime: linux/amd64 must be bootstrapped using make.bat" error can be puzzling. This message indicates that the necessary tools for cross-compilation have yet to be built.

To address this issue, you can utilize the following steps:

1. Specify the Target Environment:

set GOARCH=amd64
set GOOS=linux

These commands set the target architecture to AMD64 and the target operating system to Linux.

2. Build the Essential Tools:

go tool dist install -v pkg/runtime
go install -v -a std

These commands will build the runtime tools and standard library for the specified target.

3. Avoid Case Sensitivity:

Ensure that the target architecture is set to "amd64" (all lowercase), as the commands are case-sensitive.

Alternatively, if your Windows GOARCH is 386, you will need to build 386 tools first, which requires downloading MinGW gcc. Refer to the instructions provided by user2714852 for this approach.
