Can't build in click chroot (Ubuntu 14.10 / Go 1.2)

[Chris Wayne]

Since the latest changes, I can no longer build in my click chroot, I get a bunch of the following error:

Go type not supported in export: [0]byte

[Chris Wayne (cwayne)]

Chroot was setup to build following these instructions btw: http://blog.surgut.co.uk/2014/06/cross-compile-go-code-including-cgo.html

I get the same thing when I try to build on the device, though on my host machine it builds fine

[Chris Wayne (cwayne)]

So this works fine in a vivid chroot, just not a utopic/RTM one, so seems to be dependent ont he Go vervsion

[James Henstridge (jamesh)]

It seems we broke Go 1.2 compatibility with the latest round of changes. Hopefully the needed changes to regain that compatibility won't be too big.

With the attached branch in a utopic chroot with ubuntu-sdk-14.10 framework, I get the following:

# launchpad.net/~jamesh/go-unityscopes/bug-1431534

(with libunity-scopes-dev 0.6.7+14.10.20141010.1-0ubuntu1)

Is this something different to what's in ubuntu-rtm? The current version there should be 0.6.9+15.04.20150126~rtm-0ubuntu1:

I'll double check, I must have been using a utopic chroot

[James Henstridge (jamesh)]

An update on this issue: we've branched the binding as lp:go-unityscopes/v2 as a target for changes that are not compatible with ubuntu-rtm now.

I've also verified that the lp:go-unityscopes/v1 branch is again usable to compile scopes on ubuntu-rtm on ARM.

You'll still run into problems building in a "click chroot" environment though, since it will give you an Ubuntu 14.10 environment which is not representative of what is actually on the phone. If you manually upgrade the libunity-scopes packages within the chroot, you might have some luck. It's a shame that our tools don't make this easier :-(
