What did you do?

compile simple Hello World program to android/arm depending on this article https://rakyll.org/cross-compilation/
code:

package main
import "fmt"
func main() {
    fmt.Println("hello world")
}

GOOS=android GOARCH=arm GOARM=7 go build .

What did you expect to see?

app.apk

What did you see instead?

loadinternal: cannot find runtime/cgo
/usr/local/go/pkg/tool/linux_amd64/link: running gcc failed: exit status 1
gcc: error: unrecognized command line option ‘-marm’; did you mean ‘-mabm’?

FYI, I've deleted a comment which contained profanity and slurs. This didn't add anything to the issue itself and was in violation of the Go Community Code of Conduct.

Are the right gcc cross-compilers installed?

I think the author is trying to do a no cgo build based on what the linked article is saying.
I remember somewhere that cgo/ndk is required for android (sometime after that article was posted) but I can't find anything to link to.

yes,

yes, that's what I do @AlexRouSg

See https://github.com/golang/go/tree/master/misc/android for getting started building programs for Android. @AlexRouSg is right that the NDK is needed, and if you want to use Go in apps you'll need -buildmode c-shared to build a shared library to use through JNI. There's also GoMobile for making it easier embedding and calling of Go libraries.

app.apk

The standard toolchain will definitely not output .apk (Android app) binaries. For that you need GoMobile, or perhaps even Fyne or (shameless plug) Gio

thank you, this meaning the old implementation in the article has been changed
GOOS=android GOARCH=arm GOARM=7 go build .
