cmd/link: system linker warnings on macOS 10.14 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.

@gopherbot please open a backport for 1.12 and 1.13 since the linker warnings are appearing in both versions.

@sc0Vu could you file a new issue to report that, and describe how you upgraded Go and any other applicable config of your machine?

sc0Vu · 2020-09-22T07:01:55Z

It seems go version was hardcoded in https://go-review.googlesource.com/c/build/+/216304/5/cmd/release/release.go#367, which is prefixed with 1.14.

And I can remove these warning with the CGO_CFLAGS=-mmacosx-version-min=10.12 (found in the commit)

@einthusan how did you install Go on your Mac? This has been an issue when installing via homebrew.

einthusan · 2021-01-06T04:21:33Z

I downloaded it from https://golang.org/dl/ site itself. I was building a simple Ebiten (2D game engine in Go) game. I managed to prevent these warnings from showing when I used a flag to bypass "Metal" on OSX and use OpenGL. e.g. go build -tags=ebitengl main.go

@einthusan Go 1.14 is supposed to require macOS 10.11 as the oldest version, not 10.12. (See here.) You're right that this is not very high priority by now, as it'll stop being supported when Go 1.16 is out. However, if this is reproducible for you and if you don't mind, it can still be helpful to file an issue in case it helps us understand this better and ensure it doesn't happen in the future for newer versions.

I just upgraded to go1.14.3 (using brew upgrade go) and I see the same warning when running the test suite for my project as I did before. I have also tried cleaning the build cache with go clean -cache -modcache -testcache, but that seemed to have no effect. I am still seeing:

Is there something I have to do more than upgrade go to get the fix for this?

forzap · 2021-07-02T09:51:19Z

I suspect it somehow is similar to Julia issue (JuliaLang/julia#14182), where there's a mix-up during make caused by DARWINVER. My issue starts happening when I upgrade my Xcode from 11.5 to 12.4.

I tried all the above suggestions but it never worked (brew install / uninstall go, clean go cache, use latest Go, use Go v1.14, etc). My solution, is to install Command Line Tools version 11.5 and execute "xcode-select -s /Library/Developer/CommandLineTools" so that it points to CLT v11.5 instead of CLT v12.4 residing inside my Xcode. After that no more warning message showing.

Here's my solution:
Golang version will not change
Upgrade reinstalled protobuf proto-go-gen
The most important thing is to restart your computer
- if useless about above!!!!!!
- reinstalled xcode-select
```
sudo rm -rf /Library/Developer/CommandLineTools
xcode-select --install

Change https://golang.org/cl/381854 mentions this issue: cmd/go: rewrite TestScript/cgo_stale_precompiled to be agnostic to staleness

…aleness The configuration set by x/build/cmd/releasebot causes runtime/cgo to be stale in the darwin/amd64 release (see #36025, #35459). That staleness is mostly benign because we can reasonably assume that users on macOS will either disable CGO entirely or have a C compiler installed to rebuild (and cache) the stale packages if needed.
