Stringer complains about invalid archive header

Question

I am trying to use go generate / stringer ( golang.org/x/tools/cmd/stringer) to create String () methods for enumerations. I have problems that I think are related to a slightly different .a package format on different systems. I have this file:

package main

import (
    "math/rand"
)

//go:generate stringer -type=Foo
type Foo int;

const (
    FooPrime Foo = iota
    FooBis
)

func main() {
    //Just use rand anywhere, otherwise we get a compiler error
    rand.Seed(1)
}

Now, if I run go, generate example.go on my machine, everything will be fine: foo_string.go is created. However, on the test machine, I get:

stringer: checking package: example.go:4:2: could not import math/rand (reading export data: /usr/lib64/go/pkg/linux_amd64/math/rand.a: go archive is missing __.PKGDEF)

Now, after some digging in the code, I think I'm getting this error, because on my machine rand.a has the following header:

!<arch>
__.PKGDEF       0           0     0     644     2051   

`while on the test machine it has the following heading:

!<arch>
__.PKGDEF/      0           399   399   100644  2051  

`

I think the crucial difference is reset after PKGDEFF. gcimporter refuses to process the .a file if it does not contain __. PKGDEF header.

, gcimporter/exportdata.go :

if name != "__.PKGDEF"

:

if name != "__.PKGDEF" && name != "__.PKGDEF\"

( ) go generate example.go.
