An experimental port of Go is available for the Plan 9 from Bell Labs operating system.
The Plan 9 port of Go is available for the following architectures:
The current Go distribution has been tested successfully on:
Plan 9 requires a kernel providing the following system calls:
A fix to the pread system call is required, so pread will not update the channel offset when reading a file:
If you‘re running Plan 9 on Raspberry Pi, you’ll require the latest bcm kernel from Richard Miller.
Since Go is written in Go, you may want to bootstrap Go with Go 1.4.3, which is the latest release of Go written in C.
However, since the Go 1.4 runtime wasn't mature enough on Plan 9, we recommend you to bootstrap from a more recent version of Go, using another operating system.
First, install Go 1.4:
cd /tmp git clone -b go1.4.3 https://go.googlesource.com/go go1.4 cd go1.4/src hget http://9legacy.org/go/patch/syscall-exec.diff | ape/patch -p2 make.rc
The syscall-exec patch is required if you're running a machine with SMP enabled.
Then, set the GOROOT_BOOTSTRAP environment variable:
GOROOT_BOOTSTRAP=/tmp/go1.4
Finally, install the latest version of Go:
cd /tmp git clone https://go.googlesource.com/go cd go/src all.rc bind -a /tmp/go/bin /bin
Go is now ready to use.
First, you must have installed Go on this operating system, following the Go installation instructions.
Then, you can cross-compile a Go toolchain for Plan 9:
cd $GOROOT/src GOOS=plan9 GOARCH=386 ./bootstrap.bash
Then, the bootstrap toolchain will be available in ../../go-plan9-386-bootstrap.tbz.
Finally, you can extract this archive to your Plan 9 machine.
For example:
cd /tmp tar xzf go-plan9-386-bootstrap.tbz bind -a /tmp/go-plan9-386-bootstrap/bin /bin
Go is now ready to use.
You'll be able to use this installation of Go to bootstrap future Go releases, by setting the GOROOT_BOOTSTRAP environment variable:
GOROOT_BOOTSTRAP=/tmp/go-plan9-386-bootstrap
A binary package for plan9/386 is available.
This binary package is used to bootstrap Go on the plan9/386 builder.
cd /tmp hget -o gobootstrap-plan9-386.tar.gz https://storage.googleapis.com/go-builder-data/gobootstrap-plan9-386.tar.gz mkdir gobootstrap-plan9-386 cd gobootstrap-plan9-386 tar xzf ../gobootstrap-plan9-386.tar.gz
You'll be able to use this binary package of Go to bootstrap Go, by setting the GOROOT_BOOTSTRAP environment variable:
GOROOT_BOOTSTRAP=/tmp/gobootstrap-plan9-386
Git is not available on Plan 9. However a Git wrapper is available as a simple rc script. It includes everything you need to use the go tool.
Three Plan 9 builders are currently running and reporting the results to the Go Dashboard:
The Plan 9 port of Go is considered experimental and is still a work-in-progress. There is a number of known issues available on the Go issue tracker.
Many issues are currently open on the Go issue tracker with the OS-Plan9 label.
The most important issue is probably the lack of support for asynchronous cancellable I/O (issue 11932). An experimental implementation has been tried in CL 3231, but getting rid of the remaining race conditions would likely require runtime support.
The Plan 9 port of Go is a community-driven port. Any help to improve the Go port on Plan 9 would be highly appreciated.
Many people have contributed to the Plan 9 port of Go. Since December 2013, the Plan 9 port of Go is maintained by David du Colombier.
