What did you do?

Nothing. Issue appeared as of 9/9/22 due to

ba1ef54

Which switches to using unsafe.Slice

What did you expect to see?

Nothing since this change should've just affected latest versions i.e. 1.17 and 1.18

What did you see instead?

1.13 fails build due to

golang.org/x/sys/unix
  | src/golang.org/x/sys/unix/syscall.go:83:16: undefined: unsafe.Slice
  | src/golang.org/x/sys/unix/syscall_unix.go:118:7: undefined: unsafe.Slice

We don't support 1.13 anymore.

[ddelbosque-bread]

Fair enough - However I do see the same error on 1.15 - 1.16

[seankhliao]

We only support the 2 most recent releases, right now 1.18 and 1.19

i'm experiencing the same issue. it looks like the go devs introduced a bug affecting older versions? does anyone have any workarounds for this? I'm a new Go developer - I've inherited a project that runs on 1.15 using GOPATH (I think rather than go.mod) and am looking to get it to build so I can release some new code.

[ddelbosque-bread]

@michael-sharethis I agree, this is a breaking change for older versions.

[ianlancetaylor]

The workaround is to use an older version of golang.org/x/sys.

[michael-sharethis]

@ianlancetaylor i've tried that but I get errors like this when trying to specify an older version, this project is in GOPATH mode

Step 15/32 : RUN go get golang.org/x/sys@0.0.0-20220909162455-aba9fc2a8ff2

i didn't see golang.org/x/sys having any version listed in it's gittags...

[Expaso]

Yep!, me affected too:

Anoyone knows a fix?

[dmgk]

Something like this might work:

go get -d golang.org/x/sys/... && git -C $(go env GOPATH)/src/golang.org/x/sys reset --hard aba9fc2a8ff2

[kartik7153]

How do we fix the for dependency which is indirect?
