Please answer these questions before submitting your issue. Thanks!

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

go version go1.10.3 linux/arm

Does this issue reproduce with the latest release?

Yes, tested with go1.10.1 and then upgraded to go1.10.3

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

What did you do?

Created a simple package called github.com/triztian/carchive that imports a Binary Only Package

The packages source:

github.com/triztian/carchive/main.go:

package main

import (
	"C"
	"encoding/json"
	"fmt"

	"github.com/triztian/bop"
)

func main() {}

//export Stringify
func Stringify(n C.int) {
       p := bop.Properties{
		"n": int(n),
	}

	data, err := json.Marshal(p)
	if err != nil {
            bop.Error(err.Error())
            return
	}

	fmt.Println(string(data))
}

github.com/triztian/bop-src/props.go:

package bop

import "fmt"

type Properties map[string]interface{}

func Error(str string) {
	fmt.Println("ERROR: ", str)
}

And the sources of the BOP go file:

//go:binary-only-package

package bop

import "fmt"

And finally my $GOPATH tree before running the build command:

/home/pi/Workspace/c-archive-go/go

            └── carchive
                ├── main.go
                └── Makefile

The command used to do the build

go build -buildmode=c-archive -o libcarchive.a github.com/triztian/carchive

What did you expect to see?

A libcarchive.a file in my current directory

What did you see instead?

The following output:

go build -v -buildmode=c-archive -o libcarchive.a github.com/triztian/carchive
runtime/cgo
github.com/triztian/bop
go build github.com/triztian/bop: missing or invalid binary-only package

Exit status:

echo $?
1

And the command output of go build (-x):

I have just tested with the latest (https://golang.org/doc/install?download=go1.10.3.linux-armv6l.tar.gz), and it seems like the c-archive is produced:

go version && go build -v -o libcarchive.a github.com/triztian/carchive && ls
go version go1.10.3 linux/arm
github.com/triztian/bop
libcarchive.a  main.go  Makefile

Ok, so after the update it seems to have only worked once, now if I try to rebuild it I get the same error:

go build -v -buildmode=c-archive -o libcarchive.a github.com/triztian/carchive
runtime/cgo
github.com/triztian/bop
go build github.com/triztian/bop: missing or invalid binary-only package
Makefile:2: recipe for target 'build' failed

Is there a way to get more information with regards of what could be causing the message:

github.com/triztian/bop
go build github.com/triztian/bop: missing or invalid binary-only package

If I try to build the package on it's own it succeeds:

pi@rpi-tristian:~/Workspace/c-archive-go/go/src/github.com/triztian/carchive $ go build -v -x -n -work github.com/triztian/bop

Change https://golang.org/cl/125818 mentions this issue: cmd/go: for missing binary-only package, say where it should be

I would guess that the package is expected to be in linux_arm_shared, because using -buildmode=c-archive implies building with -fPIC. I sent CL 125818 so that the error messages indicates where the package is expected.

@ianlancetaylor and @andybons, thank you for the quick reply and for the patch. I can confirm that after moving the BOP archive into $GOPATH/pkg/linux_arm_shared the sample test case builds.
