Go: cmd/go: cross compile failed without useful error message

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

go version go1.9.2 darwin/amd64

Does this issue reproduce with the latest release?

What did you do?

I've ran GOOS=linux GOARCH=amd64 go build -v -o appname on macOS Sierra

What did you expect to see?

Successful linux cross compilation

What did you see instead?

The cross compile have been failed without any useful error messages. Just return the error code 2. But there are no any problems with go build -v -o appname.

How can I debug it?

I can't reproduce on macOS Sierra.

Try adding -x to go build and post the results.

[mingrammer]

@bradfitz Thanks for letting me know -x option.

There is a clear error message as follow:

Sorry for that I did not check carefully. Yes I got an error, this is not a problem of build command.

Thanks :)

@mingrammer have you fix the cross compilation of go-sqlite3 ?
I encounter this problem too, but can not fix it
