x/crypto/sha3: When compiling for all platforms undefined: cpu.S390X

[mjarkk]

What version of Go are you using (go version)?

My laptop:
$ go version
go version go1.10.4 linux/amd64

In docker container:
$ go version:
go version go1.12 linux/amd64

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

go env Output

What did you do?

Code on play.golang.org: https://play.golang.org/p/oUY0D25kCzz
Code:

package main

import (
	"fmt"

	"golang.org/x/crypto/sha3"
)

func main() {
	fmt.Println(sha3.New256().Sum(nil))
}

How i compiled the code:

$ GOARCH=s390x GOOS=linux go get
# golang.org/x/crypto/sha3
../../../golang.org/x/crypto/sha3/sha3_s390x.go:235:5: undefined: cpu.S390X

What did you expect to see?

$ GOARCH=s390x GOOS=linux go get
$ GOARCH=s390x GOOS=linux go build

What did you see instead?

For some reason while trying to compile a docker container after a while it did just compile but i'm not sure why it did that. After i removed the compiled binary it showed the same error again.

Hmmm, not sure what is happening here. I just tried that command sequence on my laptop and it worked fine.

One thing you could try is adding '-u' to your go get command line options. That will download dependencies automatically:

GOARCH=s390x GOOS=linux go get -u

That didn't work.
But i think that I've found it,
What i did:

• removed ~/go/src/golang.org/
• ran go get
• ran GOARCH=s390x GOOS=linux go build
• no errors

This doesn't explain why docker also didn't compile but it works.
I'm going to close this issue.
