在Windows上编译要在Linux上部署的GO程序

Question

I would like to develop on a windows environment and have installed go 1.10.1... I need to deploy my program on a linux however. Is there a way to build the go program and specify to build for linux. I have seen tons of documentation for going from linux to windows but not the other way around.

The most promising example I have tried:

set GOOS=linux 
set GOARCH=amd64 
go build filename.go

--> which just builds an exe..

Answer 1

I can confirm that what you are trying to achieve works for me on Windows 7 and Windows 10 with go 1.10.2. To check that your go install supports your desired target, run this command:

go tool dist list | find "linux/amd64"

You should make sure that you set the environment variables without any additional or hidden spaces, set them this way:

set GOOS=linux
set GOARCH=amd64

Then verify, for example this way:

echo !%GOOS%!
echo !%GOARCH%!

If the combination is not valid, you should get this message:

cmd/go: unsupported GOOS/GOARCH pair linux /amd64

After this run your build:

go build -v -x -o foreign_linux foreign.go

Following Volkers advice you can check if the created binary really is a linux binary:

type foreign_linux

You will receive some cryptic characters, but at the beginning of the first line should be ELF. If it is an exe, you will see MZ.
