Awesome! Thanks for putting these up. I wasn't aware of 9legacy, I'll have
to go looking around.

Thanks!

An alternative to building a Go 1.4.3 bootstrap environment, is to build a
Go 1.7 bootstrap environment for Plan 9 in a mainstream environment like
Linux or Mac OS X, then use it to build Go 1.7 on Plan 9.   General outline
is to:

* follow the instructions on how to clone and build Go 1.7 on, say, Linux.
* once Go is built  and installed, build a Plan 9 bootstrap
    cd $GOROOT/src
    GOOS=plan9 GOARCH=386 ./boostrap.bash

this produces the bootstrap hierarchy in ../../go-plan9-386-bootstrap.
 copy the hierarchy over to Plan  9 and set GOROOT_BOOTSTRAP to that
location, then build Go 1.7 on Plan 9.

The general explanation of bootstrapping Go is here:
https://golang.org/doc/install/source#go14

FYI, when i need to 'git clone' something on Plan 9, I mount the fs from
Linux (p9p) and do the git stuff there.

Thanks David,

I will give this a try.

You have to bootstrap from Go >= 1.4.

If you want to build the current Go source from scratch on plan9/386,
you can just do:

cd /tmp
git clone -b go1.4.3 https://go.googlesource.com/go go1.4
cd go1.4
hget http://9legacy.org/go/patch/syscall-exec.diff | ape/patch -p1
cd src
make.rc

GOROOT_BOOTSTRAP=/tmp/go1.4
cd /tmp
git clone https://go.googlesource.com/go
cd go/src
make.rc

This is documented on https://github.com/golang/go/wiki/Plan9

If you have troubles building Go on Plan 9, you can easily cross-compile
Go for plan9/arm from another operating system.

cd /usr/local/go/src
GOOS=plan9 GOARCH=arm GOARM=7 ./bootstrap.bash

Then you get /usr/local/go-plan9-arm-bootstrap.tbz, that you can extract
on your Raspberry Pi.

I was thinking about this myself. I'm more in favour of a script that downloads the go source and compiles it since it seems to be more in the spirit of plan9.

The trouble is that Go has made it harder to do now that you have to have an n-1 version of Go to compile n. This started with 1.5 but 1.5 doesn't seem to compile or run well on plan9.

Maybe a compromise would be to have tbz binaries for 1.7 and a script that takes them and uses it to compile a fresh copy from sources and cleans up the bootstrap. Otherwise, you need to cross compile from another OS. Yuck.

Hi All!

   I compiled a Go binary for use on Richard Miller's raspberry pi image in
contrib (thanks for that Richard, by the way). I threw up a link to the
binary in a previous email a week or two ago, but I think that email got
spam filtered, so I won't link it again - but, is there a good place to
make this available for ease-of-use? Woudl've been nice to just hget a tgz
and extract it when I was getting things up and running the other day,
instead of getting go set up on my linux box, compiling it, setting the
final_goroot, etc. Richard, if you're comfortable with it, I could pass it
to you to throw up on your contrib.

Thanks!

Marshall
