Go: relocation target main.main not defined

[dennismuturia]

Please answer these questions before submitting your issue. Thanks!

What did you do?

I was trying to out put some String "This is less" below is the program

package main

func main() {
    i := 3
    if i < 3 {
        println("This is less")
    }
}

What did you expect to see?

The output should be "This is less"

What did you see instead?

Each time it tells me that my main has not been defined. Yet I have already defined it. Here is a complete error message:

# command-line-arguments
runtime.main_main·f: relocation target main.main not defined
runtime.main_main·f: undefined: "main.main"

It seems like your installation is somehow broken - I cannot reproduce this issue. Does it happen with all Go programs and packages?

If you think this is a bug in Go, please provide a self-contained Go package that you are building, and exactly what commands you ran to encounter the failure.

[ianlancetaylor]

Please run your go build command with the -x option and post the output here.

Something is broken with your installation or with how you are running the go command, but I don't know what.

[jaytaylor]

I'm also running into this running from master built on March 24 2018.

Also just pulled latest go tip code and rebuilt, and still getting the same error.

@jaytaylor Please show us the complete contents of cmd/html2text.go. Thanks.

[jaytaylor]

Hi Ian,

https://github.com/jaytaylor/html2text/blob/jay/markdown/cmd/html2text.go

[ianlancetaylor]

@jaytaylor There is no main function in that file, so the error is normal and expected.

Whether this is the same problem as @dennismuturia I do not know.

[jaytaylor]

Doh.. okay. Sorry for the noise then.

[ianlancetaylor]

@dennismuturia Is this still a problem for you?

[dennismuturia]

Yeah @ianlancetaylor.

[ianlancetaylor]

@dennismuturia Above I asked for go build -x output showing the problem. Would it be possible to provide that? Thanks.

[bradfitz]

ETIMEOUT.

[VojtechVitek]

I hit this error when I accidentally defined func Main() instead of func main().

[klingerf]

I encountered this issue after upgrading my operating system to macOS 10.13.

$ go build -v -i -o kltest ./cli
github.com/linkerd/linkerd2/vendor/k8s.io/client-go/discovery/fake.init: call to external function
github.com/linkerd/linkerd2/vendor/k8s.io/client-go/kubernetes/fake.init: relocation target github.com/linkerd/linkerd2/vendor/k8s.io/client-go/discovery/fake.init not defined
github.com/linkerd/linkerd2/vendor/k8s.io/client-go/kubernetes/fake.init: undefined: "github.com/linkerd/linkerd2/vendor/k8s.io/client-go/discovery/fake.init"

Interestingly, the build succeeds if I add the -race flag. For posterity, the full -x output for the failing build is available here:

https://gist.github.com/klingerf/57e0f6dd46f3951fb6ddcea2f4674a42

After removing my go pkg dir (rm -r $GOPATH/pkg), the rebuild succeeds, and the issue is fixed. There's probably a better way to go about this than blowing away the whole pkg dir, however.

[dennismuturia]

No lance. Had reinstall the package.

@klingerf Have you tried go clean -i -r -cache ?

[klingerf]

@agnivade Ah, thanks! I hadn't seen the clean subcommand before.
