cmd/link: fails on Ubuntu Xenial due to unsupported relocations on 386, amd64

[jaccarmac]

I am on the devel (xenial) channel now, but the error started popping up before the 15.10 release. Standard Linux AMD64 build. Building from master with the most recent binary release (1.5.1) as GOROOT_BOOTSTRAP.

git reset --hard origin/master
git clean -fxd
GOROOT_BOOTSTRAP=$HOME/tmp/go ./all.bash

...
many lines of successful build steps

I'll take this one, Ubuntu is partly my fault.

@jaccarmac can you please include complete instructions to reproduce your setup so I can build a replica environment. Can you also include the complete output you receive along the way.

[jaccarmac]

My sources.list:

deb http://us.archive.ubuntu.com/ubuntu/ devel main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu devel-security main restricted universe multiverse
deb http://us.archive.ubuntu.com/ubuntu/ devel-updates main restricted universe multiverse
deb http://us.archive.ubuntu.com/ubuntu/ devel-backports main restricted universe multiverse
deb http://archive.canonical.com/ubuntu devel partner

Unix piping isn't working for the build output, so I'll add it when I figure that out.

[davecheney]

Thanks. Can you also check that golang-go is not installed and that
GOROOT is not set.

[jaccarmac]

golang-go is definitely not installed. GOROOT may be the problem. Let me check.

[jaccarmac]

Same failure with unset GOROOT before the build.

[davecheney]

If you're using linux, or actually anything that isn't windows, you should never set GOROOT.

[jaccarmac]

It's my understanding that if you install the tools in a non-standard place you have to set it. Is that not the case any more?

[davecheney]

That is correct, but my recommendation is to not do that.

If you use the tarball from the website, installed to the recommended location, you don't need to set GOROOT.

If you build from source, then the correct value will be burnt in at compile time.

If you build from source, but want to have the files in a different final location, then set GOROOT_FINAL and move the contents afterwards.

Don't set GOROOT, it leads to problems 99 times out of 100.

[jaccarmac]

Thanks! Last time I was building from source the value didn't get baked in and needed to be set if the path was outside /usr/local. In any case, even with the variable permanently unset the issue continues.
