What version of Go are you using (go version)?

go version go1.9.4 linux/amd64

Does this issue reproduce with the latest release?

No, go1.10 is fine.

What operating system and processor architecture are you using (go env)?

GOARCH="amd64"
GOBIN=""
GOEXE=""

GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/ncw/go"
GORACE=""
GOROOT="/opt/go/go1.9"

What did you do?

goroot/src/golang.org/x/sys/unix/zsyscall_solaris_amd64.go:22:3: too many errors

Note that with go1.10 it works correctly.

$ go version
go version go1.10 linux/amd64
$ rm -rf /tmp/goroot ; mkdir /tmp/goroot ; export GOPATH=/tmp/goroot
$ go get golang.org/x/sys/unix
$ GOOS=solaris GOARCH=amd64 go install golang.org/x/sys/unix

I suspect this might need d1fbe07 from the 1.10 branch.

Fix is already on tip in CL 93836 and CL 94896.

This doesn't appear to be fixed in go1.9.5 :-(

@andybons Can we re-open?

We would need to also backport CL 94018. Sorry for forgetting about that one.

I don't know whether we are doing a 1.9.6 release or not. @andybons

I have no issue with doing a 1.9.6 release

Change https://golang.org/cl/110077 mentions this issue: [release-branch.go1.9] cmd/compile: permit go:cgo_import_dynamic anywhere

…here

It's used on Solaris to import symbols from shared libraries, e.g., in
golang.org/x/sys/unix and golang.org/x/net/internal/socket.
We could use a different directive but that would require build tags
in all the places that use it.

Fixes #23939
