Does this issue reproduce with the latest release?

Yes

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
../../../golang.org/x/crypto/sha3/sha3_s390x.go:244:5: undefined: cpu.S390X
../../../golang.org/x/crypto/sha3/sha3_s390x.go:253:5: undefined: cpu.S390X

../../../golang.org/x/crypto/sha3/sha3_s390x.go:280:5: 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.
