what's mean about it?what can I do to install go

[Memroy91]

[root@redhat2 src]# ./make.bash

Building C bootstrap tool.

cmd/dist
go tool dist: unknown architecture: ppc64

[davecheney]

Which version of go are you using? You need go 1.5 or later for ppc64
support. (I'm assuming that your hardware is ppc64)

yes,my hardware is ppc64,but i find that if i want to install go 1.5,i need to install go1.4 first?is this a bug?

[Memroy91]

Because of go1.4 does not support ppc64, I just need to install go1.5, if installation go1.5 must install go1.4, what am I supposed to do, this is not a dead cycle

[davecheney]

Ahh, yes.

You will need a bootstrap version of Go, but you can do this.

1. Install Go 1.5 from source on an intel machine (you may also need go 1.4
   to bootstrap go 1.5)
2. cd go/src and run GOOS=linux GOARCH=ppc64 ./bootstrap.bash

This will make a .tgz two directories up, you can copy this to your ppc64
machine, unpaxk it then use that as your GO_BOOTSTRAP_ROOT.

Let me know how you go, if you have a problem will write up a blog post
with a detailed procedure.

Let me know how you go, I can write up a more comprehensive procedure if
you get stuck.

ok ,thanks

I hava installed Go 1.5 from source on an intel machine(I used go 1.4 to bootstrap go 1.5),but I don't know is properly installed.when i cd/bin ,then input go version ,it shows go version go1.4.2 linux/amd64 ?
but i see some logs shows Go version is "go1.5.1".

install logs:

../test

API check

Go version is "go1.5.1", ignoring -next /data/packages/go/api/next.txt

ALL TESTS PASSED

[davecheney]

It sounds like you may have combined the source for go1.4 and go 1.5.

Never the less, if you change to.the go 1.5 directory and run then
bootstrap script above you may be able to produce a working bootstrap go
version which will let you build go 1.5 on ppc64

I got a folder : go-linux-ppc64-bootstrap,copy the folder to ppc64 machine and then put it under the folder "/root/go1.4" ,and then use it to bootstrap go 1.5?

[davecheney]

Unpack it to /root on the target, you'll get something like
go-bootstrap-linux-ppc64, the set

GO_BOOTSTRAP_ROOT=/root/go-bootstrap-linux-ppc64 and then run ./all.bash

some error occured when i use it to bootstrap go 1.5.
Although have compiled out bin folder,but i can't execute it.report error:
-bash: /usr/local/go/bin/go: cannot execute binary file

Until there's a bug, please move this discussion to a forum of some sort.

See https://golang.org/wiki/Questions for potential venues.

Please be aware that once you get go1.5 built on ppc64, it is not
complete yet for ppc64 or ppc64le. It does not provide support for
external linking which is necessary for building applications like
Docker which link against external (non-Go) packages.

I opened an issue on this against ppc64le.
#11184.
There are CLs to add this support for ppc64le but they are waiting to be
reviewed.

@Terryshakj I have written up the procedure here http://dave.cheney.net/2015/10/16/bootstrapping-go-1-5-on-non-intel-platforms

If there are errors or omissions, please open a thread on the mailing list. Do not continue the discussion on this issue as it is closed.

Thanks
