goapp serve not working

[vorcigernix]

This may be something I overlooked, but when I run my app (almost helloworld) with goapp serve, it fails to build. Publishing to gae works fine though. Is this known issue?

Not sure. Let me check.

@vorcigernix I don't see anything in the github.com/google/http2preload package that would prevent building your app.

What do you mean by "almost helloworld" and what is error message. Also, why do you think it is related to http2preload package?

[vorcigernix]

It worked before I added http2preload. Might be something else though. Here is the code:

package hello

import (
	"html/template"
	"net/http"

	"github.com/google/http2preload"
)

func init() {
	m, err := http2preload.ReadManifest("push_manifest.json")
	http.Handle("/", m.Handler(handleRoot))
	if err != nil {
		panic(err)
	}

}

func handleRoot(w http.ResponseWriter, r *http.Request) {
	tmpl := template.Must(template.ParseGlob("templates/index.html"))
	if err := tmpl.Execute(w, nil); err != nil {
		http.Error(w, err.Error(), http.StatusInternalServerError)
	}
}

So, what is the actual build failure error message?

Your issue is with the local setup. The problem is here: /Users/adamsobotka/Downloads/go_appengine/goroot/pkg/darwin_amd64/github.com/google/http2preload.a: object is [darwin amd64 go1.7.1 X:framepointer] expected [darwin amd64 go1.6.3 (appengine-1.9.48) X:none]

The package was compiled with Go1.7 but App Engine is obviously using Go1.6. Try deleting /Users/adamsobotka/Downloads/go_appengine/goroot/pkg/darwin_amd64/github.com/google/http2preload.a.

Closing as this is a non-package issue.

[vorcigernix]

Yeah, thanks, works now.
