cmd/link: system linker warnings on OSX 1.14 when using cgo #36025

tjamet · 2019-12-06T20:29:11Z

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

$ go version
go version go1.13.5 darwin/amd64

Does this issue reproduce with the latest release?

yes, in fact, is has been introduced by the latest release

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

What did you do?

Install go 1.13.5 from official release using the installer. This replaced my previously installed version

Then, I ran a program, I had previously run using go 1.13.1 using go run main.go, importing the sqlite package, using CGO

Here is the snippet that reproduces the problem:

package main

import (
	"database/sql"
	"log"

	_ "github.com/mattn/go-sqlite3"
)

func main() {
	db, err := sql.Open("sqlite3", "test.db")
	if err != nil {
		log.Fatalln("could not open database:", err)
	}
	defer db.Close()
}

What did you expect to see?

No output on stdout/stderr.
This output was not shown with my system (10.14.6 (18G95)) using go 1.13.1
I am unsure the issue is linked to go or to go-sqlite3

What did you see instead?

When running the run command, or the go build command, I have the following output:

CC @andybons @dmitshur

Is anybody else seeing this? Did we build the 1.13.5 release on macOS 10.15?

@tjamet Do you see this problem with other Go programs?

andybons · 2019-12-06T22:03:47Z

@ianlancetaylor the release is built on 10.15, yes. It may be that we need to explicitly set a target of macOS when building. See #35459.

@cagedmantis @toothrot

andybons · 2019-12-06T22:13:00Z

@tjamet can you provide the output of go build -x?

networkimprov · 2019-12-07T08:57:58Z

Looks like a dup of #22281 & #35193 & #33968

@eliasnaur @odeke-em

tjamet · 2019-12-08T16:17:26Z

indeed, it looks very much like a duplicate of those tickets. Sorry about that!
I didn't see the problem with other programs @ianlancetaylor I am not using CGO for any other program though.

here is the output of go build -x

I don't have a mac machine handy (and am just learning the x/build/cmd/release code), but is setting MACOSX_DEPLOYMENT_TARGET in x/build/dashboard/builders.go#L528 sufficient?

Edit: I'll work on answering this question

Also experiencing this on MacOS 10.14 with Go 1.13.5 with cgo on a different project. Downgrading to Go 1.13.4 makes the warnings go away.

@cagedmantis has been working on this all week, and it's a bit more involved than we first expected. We're still working on it, and will keep this thread updated.

This issue got resolved with go version go1.13.6 darwin/amd64. Thanks a lot.
