The binary I built was specifically for arm (or more accurately, for the
raspi), on which I initially spent a chunk of time trying to get 1.4
building; eventually, as suggested here, cross-compiling on my Linux box
was how I ended up getting things working. However, that process wasn't
really intuitive, and felt a good chunk like wasted time.

I figured having a binary available would save people some hassle; there's
no real reason to make everyone cross-compile the binary, especially with
as small a target platform as the pi, and for people like myself who
weren't immediately aware of exactly what to do, it's more things to figure
out for no real reason. Bandwidth is cheap, the binary's small, so I
figured having it around would help other people who install plan 9 on
their Pi to check it out.

I'm already hosting it myself, but it seems like my link got me
spam-filtered. I'm more just wondering where to make it more obvious that
it's available, so noobies like myself can just grab it and play instead of
having to spin the same wheels I did.

Thanks!

Thanks David,

These binaries are great as a starting point to compile newer versions of Go.

I almost fully automated the preparation of my 9front rpi sd card images. Cross compiling from plan9 386 to plan9 arm using the bootstrap fails with this error:

Install: './install' not found

Maybe cross compile isn't working with Go on plan9 yet?

Thanks,
Chris

I don't know about bootstrap.sh, but cross-compiling works fine on Plan 9
using make.rc.

To cross compile with make.rc do you just set GOARCH and GOOS and just run it?

Yes and you can add the --no-rebuild flag to prevent cmd/dist to remove the
existing binaries.

For example:

℅ GOOS=plan9 GOARCH=arm make.rc --no-rebuild

I tried this command with both go 1.7.3 and master branches. Both fail right after “#### Building packages and commands for host, plan9/386” with an error “install: ./install not found.”

It seems like the go bootstrap tool is trying to call a binary called “install” but there are none on my system. Is there such a command on p9bl? Maybe 9front doesn’t have it?

It works fine if I don’t try to cross compile to plan9/arm or even linux/386.

'install' is from BSD. It does not exist in Plan 9.

Thanks David, Stanley,

I managed to get the cross compile to work using the 9legacy go binaries and the git script.

The workaround for the error I received before is to create a dummy rc script called 'install' and put it into my /bin. The go make.rc script calls it and continues on seemingly fine afterwards.

Re: [9fans] Making available a pre-compiled go binary for Miller's plan-9 Pi image (Chris McGee)

I've updated the Go binary packages with the fix to make.rc:

http://9legacy.org/download/go/go1.7.3-plan9-386-bootstrap.tbz
http://9legacy.org/download/go/go1.7.3-plan9-amd64-bootstrap.tbz
http://9legacy.org/download/go/go1.7.3-plan9-arm6-bootstrap.tbz

Thanks David,

Will you add new Go releases there as they come out so that we can bootstrap from previous releases?

Also, the Git script is working quite well for me. Thanks for that too.

Yes. I've scripted the process to do that.

You're welcome :-)
