Hi Go nuts,

We think this is pretty close to Go 1.5 Release Candidate 1, which we hope to issue next week.
The final version of Go 1.5 should be out by mid-August.

I am unsure what I'm doing wrong at this point.

I can cross-build on go1.4.2 from Linux to FreeBSD ok.  Also on 1.4.2 I can cross-build for linux/arm (raspberry pi).

But in this beta I get weird messages about environment variables that were never set 
"go install: cannot install cross-compiled binaries when GOBIN is set:

GOBIN is not set.

Also, is buildmode=shared not supported for anything but linux? That's a complete showstopper for me (we've got a ridiculously tight image to put things on by today's standards on some of our platforms)

I should have mentioned I'm trying to cross build today from OS X.

In this release -buildmode=shared is only supported on amd64 GNU/Linux
(if you can use gccgo it should work for most platforms). It would be
great to have people work on extending the support, but that work
won't go into this release.

Ah, understood.  Well I might even be able to do this at work eventually if someone doesn't beat me to it! :-)

(we have special days set aside for pet projects, but they only occur about 2 times/year)

Thanks for the speedy reply!

FWIW, I'll be working on supporting other architectures on Linux early
in 1.6. But not other OSes.

Cheers,
