Bug#658421: golang-weekly: "go build" and "go install" fail

[Justus Winter]

Hi Ondřej,

I've been seeing the same error with 2012.02.22-3 and I think it is
because the library archive is older than the go source files, hence
the archive is considered old and go install tries to rebuild it.

The following workaround solves this, dunno why the timestamps are
wrong in the first place:

find /usr/lib/go/pkg -type f -exec touch {} +

Cheers,
Justus

Ah, thanks for the hint. The timestamps are different because I copy
the source manually
from debian/rules.

That problem has easy solution, I am adding --preserve-timestamp
option to install invocation.

Could you retry it, when 2012.02.22-4 hits the debian? (Building now,
uploading in a moment.)

Yes, the new package works nicely. Thanks for the quick response :)

Hm, the issue is back:

% make
go install vgo/logic
open /usr/lib/go/pkg/linux_amd64/runtime.a: permission denied
make: *** [vgo] Error 1
% find /usr/lib/go/src/pkg/runtime -newer /usr/lib/go/pkg/linux_amd64/runtime.a
/usr/lib/go/src/pkg/runtime
/usr/lib/go/src/pkg/runtime/pprof
/usr/lib/go/src/pkg/runtime/cgo
/usr/lib/go/src/pkg/runtime/debug

But this time my workaround isn't working anymore, don't know what
triggers the rebuild this time...

That's true. They wasn't necessary in previous versions. I just cannot
understand the whole concept of "we compile everything, but we still
need the source code".

I'll include the cmd/ sources in next upload of golang-weekly.

Sorry it took so long to get back to you. I didn't have a chance to try
2012.02.22, but I'm still having problems with 2012.03.04. I get:

$ go install ./
load cmd/cgo: package cmd/cgo: no Go source files in /usr/lib/go/src/cmd/cgo

And indeed, the only source for anything under .../src/cmd/ is the
doc.go file for each command. The source for .../src/pkg/ seems to be
intact.
