go @1.14: SIGILL: illegal instruction

OS X 10.11.6

go_bootstrap install -gcflags=all= -ldflags=all= -i cmd/asm cmd/cgo cmd/compile cmd/link: exit status 2

Ran into the same issue on macOS 10.14.6.

[andersm (Anders Montonen)]

This is probably this issue: ​https://github.com/golang/go/issues/37459. Go 1.14 introduced a dependency on the AVX instruction set, which breaks running on older hardware. The issue is set to be fixed in Go 1.14.1 (​https://github.com/golang/go/issues/37478).

I don't know when the update to 1.14.1 is supposed to come along, so here you go <​https://github.com/macports/macports-ports/pull/6470> if you want the patch now.

Fixes build for me, as expected.

[dbl001 (dbl)]

I am ok waiting for Go 1.14.1, but, for some reason, ‘uninstall’ does not remove the Go port. E.g. - $ port list go go @1.14 lang/go

How do I uninstall lang/go 1.14?

Alternatively, do you have instructions on how to apply the patch? E.g. Is this procedure?

try

port -v installed go

and see what that gives you.

I get this, at the moment, on 10.6.8:

$ port -v installed go
The following ports are currently installed:
  go @1.5.1_0 platform='darwin 10' archs='x86_64' date='2020-02-27T18:00:07-0800'
  go @1.6.3_0 platform='darwin 10' archs='x86_64' date='2020-02-27T19:35:39-0800'

$ port -v installed go
None of the specified ports are installed.

[kencu (Ken)]

yeah -- so you don't have any go installed.

port list

is not doing what you thought it was doing :>

Re: applying the patch -- have you ever patched anything? It's not too hard.

From a github PR you can do this:

wget https://patch-diff.githubusercontent.com/raw/macports/macports-ports/pull/6470.patch

and then patch -p1 < 6470.patch from the top of the ports tree.

hopefully some of what I just said makes sense to you. Otherwise ci42 could hit the "commit" button on the PR if he wants to ...

[dbl001 (dbl)]

The patch worked.

$ go version
go version go1.14 darwin/amd64

I'm curious ... after I uninstalled go 1.4 and all prior versions of the go port, then ran 'sudo port selfupdate' the, 'sudo port upgrade outdated' why did it start building the go port agin?
