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:

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?

@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

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

andybons picture andybons on 6 Dec 2019

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

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.

I've been able to reproduce this issue using the go1.12.15 release.

cagedmantis picture cagedmantis on 27 Jan 2020

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

Backport issue(s) opened: #36845 (for 1.12), #36846 (for 1.13).

Remember to create the cherry-pick CL(s) as soon as the patch is submitted to master, according to https://golang.org/wiki/MinorReleases.

I'm still seeing this, on go 1.13.6 and 1.13.7 running on macOS Catalina (10.15.2). I only see problems if I use the homebrew version of go (from brew install go or brew upgrade go).

...

...

If I compile go myself from the git tree on tag go1.13.6 on my laptop the problem does not happen; so I assume this is a mismatch between the version compiled by homebrew and my environment.

(aside: there's no tag for go1.13.7 yet)

@itsmontoya Correction, it will be the 13.9 release (estimated release month is March).

That's a bummer, but I appreciate the updated @cagedmantis! I'll probably revert my version down in the meantime.

itsmontoya picture itsmontoya on 13 Feb 2020

@cagedmantis should we close this issue and #35459, and use the backports (#36846 and #36845) for tracking the 1.13 and 1.12 releases?

Closing this issue, since it has been resolved in 1.14, makes sense to me. 馃憤

Makes sense to me. I was keeping it open until the backports were in.

cagedmantis picture cagedmantis on 18 Feb 2020

Although I'm not sure about #35459. The Mach-o headers have not been changed by the changes we made. I'm not sure that issue should be closed.

cagedmantis picture cagedmantis on 18 Feb 2020

hey so ive been reading through this now closed issue. I was seeing the same issue initially with macos 10.15.4 and golang 1.12.17. So I updated to the latest 1.14.2 and am now seeing:

Any idea what is causing this and how to resolve this?

@Anjali-Saha As you say, this issue is closed, and the problem you mention doesn't seem to have anything to do with this issue. Please open a new issue or use a forum (see https://golang.org/wiki/Questions). Thanks.

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?

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

networkimprov picture networkimprov on 22 Sep 2020

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)
