All the errors seem related to the old Rune size. I suspect you're running an old system and it's likely to not have nsec and tsemacquire syscalls either.

If you believe the system is up-to-date, you can cross compile a simple Go program using 1.5 or later targeting GOOS=plan9 GOARCH=386 from a Linux/OSX or Windows box and see if it runs on your system.  That might give you more info.

Hi all,

I've been getting interested in programming in Go recently and it's my understanding that at some point in time, Plan 9 was a supported environment in which one could bootstrap and use Go?

I've tried a few different versions; 1.2.2, 1.4.2, 1.5.2, just following the directions that I found on a blog somewhere, i.e:

tar xf go 1.4.2.tar
cd go-go1.4.2/src
./all.rc

But it fails almost immediately trying to bootstrap Go:

cpu% ./all.rc
# Building C bootstrap tool.
cmd/dist

# Building compilers and Go bootstrap tool for host, plan9/386.

I get a fair number of these errors for various header files, then some more worrisome output:

At that point the build fails and I drop back to the rc prompt.

While the example I cite above is for version 1.4.2, I believe the failure mode is pretty much the same for both earlier and later versions that I've tried to build.

Is my Plan 9 installation "too old"? I'm using pretty bog-standard Fourth Edition on this particular instance; 9atom doesn't seem to get along with VMware ESXi (at least, not last time I checked).

Any help greatly appreciated! I'd love to be able to use Go within Plan 9.

Thanks,

Sean
