How to Cross-Compile Go Programs from Windows to Linux?

Cross Compiling from Windows to Linux

Envision running a program compiled on a Windows machine flawlessly on a Linux system. Cross-compiling makes this scenario a reality. However, certain challenges arise when attempting to cross-compile from Windows to Linux.

Problem: Attempting to compile a program with "go build" while specifying a Linux target on Windows results in an error: "runtime: linux/amd64 must be bootstrapped using make.bat".

Answer: This error indicates a lack of necessary tools for cross-compilation. To resolve this issue, follow these steps:

1. Ensure that your Windows GOARCH is set to "amd64".

2. Execute the following batch script to build the required tools:

   set GOARCH=amd64
   set GOOS=linux
   go tool dist install -v pkg/runtime
   go install -v -a std

Note: If your Windows GOARCH is "386", you will need to download mingw gcc and follow the instructions provided by user2714852.

For additional guidance, refer to the tutorial available at https://golang.org/wiki/WindowsCrossCompiling for instructions on cross-compiling from Linux.
